I am having a strange issue in Firefox 3.5.2 with F5 refresh.
Basically, when I focus on an input field and hit f5 the contents of that input field gets copied to the next form field after the F5 refresh.
But, if you inspect the HTML source code, the values are correctly loaded.
I am not having this issue in IE8 or Safari 4.0.3.
The problem does not occur if I do a hard refresh or run window.location.refresh(true).
After F5 Refresh: http://i805.photobucket.com/albums/yy339/abepark/after.jpg
Here's an overview of what's going on.
I believe the thing you should look into is the autocomplete attribute,
you should set it to off on the input box. However be careful since this will trigger two effects.
When you refresh the page it won't remember the old values
The default dropdown of the already used values on that input box will also be disabled.
If you want to keep the second behavior you should set the autocomplete attribute back to on with JS.
Browsers can remember form field contents over a refresh. This can really throw your scripting off if it is relying on the initial value of a field matching what's in the HTML. You could try to prevent it by calling form.reset() at the start.
Different browsers have different strategies for detecting when a form or a field is the same as in the previous page. If you have clashing names, or names that change on reload, it is very possible to end up confusing them. Would have to see some code to work it out for sure.
In the backend, I am using ASP.NET MVC 1.0 with the Spark View engine. When I examine the source code after an F5 refresh in Firefox 3.5.2, the page renders correctly; however, if you look at the page visually the adjacent form field field gets populated with the value from the previous field.
I included enough code so you can just get an idea of what I'm trying to do.
Again, the rendering is fine and the final view/HTML code is fine. It's what I see on the screen that is incorrect. I am using hidden vars; but the issue occurred before using it as well.
Note in the code below, I have 2 distinct ID fields: "date_{projectTask.ProjectTaskId}" and "finishDate_{projectTask.ProjectTaskId}, which gets renders to something like "date_1" and "finishDate_2".
<table>
<for each="ProjectTask projectTask in projectTasksByProjectPhase">
<input type="hidden" value="${projectTask.ProjectTaskId}" />
<tr>
<td class="date">
<div class="box">
<div class="datefield">
<input type="text" id="date_${projectTask.ProjectTaskId}" value="${startDate}" /><button type="button" id="show_${projectTask.ProjectTaskId}" title="Show Calendar"><img src="~/Content/yui/assets/calbtn.gif" width="18" height="18" alt="Calendar" ></button>
</div>
</div>
</td>
<td>
<div class="box">
<div class="datefield">
<input type="text" id="finishDate_${projectTask.ProjectTaskId}" value="${finishDate}" /><button type="button" id="finishShow_${projectTask.ProjectTaskId}" title="Show Calendar"><img src="~/Content/yui/assets/calbtn.gif" width="18" height="18" alt="Calendar" ></button>
</div>
</div>
</td>
</tr>
</for>
</table>
FYI: ${} are used to output variables in the Spark View engine.
I am also using the YUI 2.7 Connection to make Ajax calls to update the datebase for "change" and "enter/tab key press" events. I am able to verify that the AJAX calls are made correctly and the form field values are still valid.
The problem occurs when I just do a F5 refresh; for some reason, the "finishDate_1" gets populated with the value from "date_1".
This problem occurs just by clicking on "date_1" and hitting F5; so, the adjacent field just gets populated even if there are no AJAX calls.
Here's the Javascript code I call towards the end of the body"
YAHOO.util.Event.onDOMReady(
function() {
var idList = YAHOO.util.Dom.getElementsBy(function (el) { return (el.type == 'hidden'); }, 'input');
len = idList.length;
var startDatePickers = new Array();
var finishDatePickers = new Array();
for (var i = 0; i < len; i++) {
var id = idList[i].value
startDatePickers[i] = new DatePicker("date_" + id, "show_" + id, "cal_" + id);
startDatePickers[i].valueChanged.subscribe(updateDate, 'S');
finishDatePickers[i] = new DatePicker("finishDate_" + id, "finishShow_" + id, "finishCal_" + id);
finishDatePickers[i].valueChanged.subscribe(updateDate, 'F');
}
}
}
The form field gets copied over before any Javascript code is processed because I call the Javascript code towards the end of the body after all HTML is rendered. So, I'm guessing it's a refresh issue in Firefox? What do you guys think?
As you can see above, I created my own calender date picker objects which allows you to either enter the date in the text manually or by clicking on a button to view the calendar and select a date. Once you enter or select the date, an AJAX call will be made to update the datebase in the back end.
Thanks everybody for the quick responses.
#Anonymous: whoever you are, you are awesome!
#bobince: thanks for the feedback as well.
I added a dummy form tag with the attribute autocomplete="off" and that solved the problem!
I was scratching my head because I didn't get this issue in Safari 4.0.3 or Internet Explorer 8.
<form action="" autcomplete="off">
<!-- my code -->
</form>
The values were loading correctly in the back end (ASP.NET MVC 1.0/Spark View engine) and the HTML source code reflected this, but the input field values were not getting populated correctly. I was using the YUI Connection Manager and Javascript to support edit-in-place and the date pickers.
I tried changing the XHR call to a GET call instead of POST and the same issue was happening.
Anyway, the problem was that the Firefox was not setting the correct values for the input fields for F5 refreshes.
Again, thanks so much! You guys rock!
All element id's must be unique, if two elements have same id's then that could be reason why Firefox inserts same values to elments that didn't orginally have those values entered.
I had a similar problem related to my question at Input control shows incorrect value, even 'though inspect element shows the right value is there
The problem occurred for me in Firefox, but not Chrome, for some but not all controls on the form, and when I pressed F5, but not ctrl-F5.
The "dummy form" seems to have resolved it for me.

We are re-designing a site and part of that re-design involves making the site accessible to screen readers and the like. I'm using latest version (2.8.0). Here's what's happening --- validation for all text, select and textarea fields in our forms work perfectly. In order to be accessible, checkbox and radio inputs are wrapped in tags. The html for a set of checkboxes looks like this:
<div class="form-group">
<p id="applicant_type_desc" style="margin-bottom: 6px;"><strong>I am: <span class="text-danger" aria-hidden="true">*</span><span class="sr-only">Required</span></strong> <em class="small">(check all that apply)</em></p>
<div class="checkbox">
<label id="applicant_type_patient_desc">
<input type="hidden" name="applicant_type_patient" id="" value="N">
<input type="checkbox" name="applicant_type_patient" id="applicant_type_patient" value="Y" {checked_applicant_type_patient} aria-labelledby="applicant_type_desc applicant_type_patient_desc" data-parsley-multiple="type" data-parsley-error-message="Please specify whether you are a patient, relative, employee or other.">
A patient
</label>
</div>
followed by more checkbox divs without error messages and ended with an end div for the for form-group wrapper.
If I load the form and click 'submit', all the text fields are validated properly. If I add 'required' to the checkbox above, when 'submit' is clicked nothing happens and the form is submitted with no validation at all.
The same thing happens when I try to validate a radio button set as required.
There is some custom jQuery and parsley code which creates a div to hold all the error messages and transforms the error messages into links to the field id so that a screen reader can follow them and focus on the field in error. But imho, this should have no effect on why the form validation doesn't kick in.
I'm absolutely baffled.
FYI - I tried this using an earlier version (2.0.3) of parsley and the validation actually worked, although all my custom error processing was ignored.
Any insight would be greatly appreciated.
As it turns out, parsley handles the errorswrapper element differently for text, textarea and selects then it does for checkboxes and radio buttons.
The starting wrapper element for text, textarea and select contains the parsley-data-id attribute whereas checkbox and radio button elements contain the parsley-data-multiple attribute whether that was generated by parsley or entered manually in the html.
My code was looking for parsley-data-id and, of course the jquery selector failed and generated an error. A colleague was able to spot this for me while we were looking at the page in chrome inspector. Once i saw the error, making a simple adjustment to the form:error event function allowed everything to work.
I have this problem I'm facing. I have been working on a project using Grails based on the advice from a friend. I'm still a novice in using Grails, so any down to earth explanation would be highly welcomed.
My project is a web application which scans broken or dead links and displays them on a screen. The main application is written in Java, and it displays the output (good links, bad links, pages scanned) continuously on the system console as the scan goes on. I've finished implementing my UI, controllers, views, database using Grails. Now, I will like to display actively in a section of my GSP page say forager.gsp the current link being scanned, the current number of bad links found and the current page being scanned.
The attempts I have tried in implementing this active display include storing the output my application displays on the console in a table in my database. This table has a single row which is constantly updated as the current paged scanned changes, number of good links found changes and number of bad links found changes. As this particular table is being updated constantly, I've written an action in my controller which reads this single line and renders the result to my UI. The problem I'm now facing is that I need a way of constantly updating the result being displayed after an interval of time in my UI. I want the final output to look like
scanning: This page, Bad links: 8, good links: 200
So basically here is my controller action which reads the table from the database
import groovy.sql.Sql
class PHPController {
def index() {}
def dataSource
def ajax = {
def sql = new Sql(dataSource)
def errors = sql.rows("SELECT *from links")
render (view: 'index', template:'test', model:[errors:errors])
}
}
Here is the template I render test.gsp
<table border="0">
<g:each in="${ errors }" var="error">
<tr><td>${ error.address }</td><td>${ error.error}</td><td>${ error.pageLink}</td></tr>
</g:each>
</table>
For now I'm working with a test UI, which means this is not my UI but one I use for testing purposes, say index.gsp
<html>
<body>
<div><p>Pleaseeee, update only the ones below</p></div>
<script type="text/javascript">
function ClickMe(){
setInterval('document.getElementById("auto").click()',5000);
alert("Function works");
}
</script>
<div id="dont't touch">
<g:formRemote url="[controller:'PHP', action:'ajax']" update="ajaxDiv"
asynchronous="true" name="Form" onComplete="ClickMe()" after="ClickMe()">
<div>
<input id="auto" type="button" value="Click" />
</div>
</g:formRemote>
<div id="ajaxDiv">
<g:render template="/PHP/test"/>
</div>
</body>
</html>
The div I'm trying to update is "ajaxDiv". Anyone trying to answer this question can just assume that I dont have an index.gsp and can propose a solution from scratch. This is the first time I'm using Grails in my life so far, and also the first time I'm ever dealing with ajax in any form. The aim is to dynamically fetch data from my database and display the result. Or if someone knows how to directly mirror output from the system console unto the UI, that will also be great.
It sounds like a form would be appropriate for your needs. Check out the Grails documentation on forms. You should be able to render a form with the values you would like without too much trouble. Be sure to pay attention to your mapping and let me know if you have any questions after you have set index.gsp up to render a form for your values.
I'm experiencing a problem ONLY in Chrome where an Ajax response is not being displayed. Oddly, when I hover over the page's main menu, the response shows up and also stays when I move the mouse away again from the main menu.
Here is a more specific description:
The page contains a search box that allows the user to start typing a contact name. As the user types, an ajax request is made to return a list of suggested contacts. The user can then click on a radio button corresponding to a contact in that list to display all the contact information of that one person. Up to that point everything works fine. But now if the user goes back to the search box to change his search, the previously returned list of contacts goes away, but the new one from the new search does not show up. It is the click on the radio button that causes the following search not to display any ajax responses. The odd thing now is that the response does show up if the user hovers over the main menu at the top of the page (which uses css), and it also stays if the user moves the mouse away again from the menu and everything works fine afterwards. Here is the page structure:
<div id="fixedTopBar">
<?php
include("include/mainMenu.php");
?>
</div>
<div id="pageContent">
<div id="contactListContainer">
<form>
<input id="contactSearchBox" type="text" autocomplete="off" onkeyup="showHint(this.value, 'contactList', null , 'include/ajax/getContacts.php')">
</form>
<div id="contactList">
<form>
<?php
echoAllContacts(getContactsFromDatabase());
?>
</form>
</div>
</div>
<div id="profile"></div>
The ajax request is made with the showHint() function in the id="contactSearchBox" input, and the response is displayed within the id="contactList" div.
So in short, the click on a radio button causes the problem, and hovering over the top menu solves the problem (very strange no?).
Please let me know what other code you need to track down the problem if you have any ideas, or if anything I said did not make sense.
Thanks in advance!
I was able to solve my problem with some css:
The id="contactListContainer" div was positioned: fixed ...once I positioned it absolute, the problem was gone. Now, to actually position it fixed and not have the problem, I also had to add the position:fixed or position:absolute property to the child div id="contactList".
What code would I start with? I know onChange won't work with input=hidden. Would it be best to write something to re-name the hidden fields and then build it into the existing onchange for the dropdown?
Not 100% sure what you are wanting to do. I don't believe its possible to make a tag with <input type="hidden" show on the browser unless you change its type.
Just tested this at W3Schools and worked on Chrome
<input type="hidden" value="OK">
<p id="demo">Click the button below to set the type attribute of the button above.</p>
<button onclick="myFunction()">Try it</button>
<script type="text/javascript">
function myFunction()
{
document.getElementsByTagName("INPUT")[0].setAttribute("type","button");
};
</script>
<p>Internet Explorer 8 and earlier does not support the setAttribute method.</p>
Granted this code obviously states it won't work with IE8 or earlier and it would probably be better to set the id attribute for each of the hidden fields you want and probably use something like document.getElementById(IDVALUE).setAttribute("type", "text") Though this will allow the user to change the value in the tag.
Now all that is left is to give a dropdown with an onChange function that runs a statement like above based on what was selected.
I've noticed that browsers do not store form values until the form is submitted, which means that if you're using AJAX instead of a standard form submit, your browser's auto-fill is never populated. Is there a way to force populate your browsers auto-fill/auto-complete so that I can have this convenience with forms that are submitted via AJAX? It's annoying to go to my AJAX page and have to type in the same things in the form fields every time because the browser doesn't remember them.
My question is pretty much identical to the this one, except that only a work around in FireFox is provided as the accepted answer to that question. I'm looking for a solution that works in all major browsers (at least Chrome, FF, and IE), if there is one.
Note: I am not talking about AJAX auto-complete plugins, which is what almost always pops up when googling this question. I am talking about your browser's built-in auto-complete or auto-fill that helps you fill out forms by remembering what you entered in the past.
For anyone who's still trying to solve this, seem like I've found the answer.
Chromium tries to recognize the submit event, even if you preventDefault and handle the actual submission yourself.
That's it, you need to preventDefault the submit event, not the click event.
This worked on Chrome, Edge and IE 11 at the time of writing (I'm too lazy to download and test it on Firefox).
Here's your form:
<form method="POST" id="my-form">
<label>Email</label>
<input autocomplete="email" type="email" name="email">
<button type="submit">Subscribe</button>
</form>
Notice the autocomplete attribute. These are all the possible values that you can use for autocomplete.
In JavaScript, simply do this:
$("#my-form").on("submit", function (ev) {
ev.preventDefault();
// Do AJAX stuff here
});
The browser will remember whatever email you've entered on clicking subscribe button.
I have also come across this; there doesn't seem to be a great solution, certainly not a cross browser one, but here is one for IE I haven't seen anyone mention:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<SCRIPT>
function subForm()
{
window.external.AutoCompleteSaveForm(f1);
f1.submit();
}
</script>
</HEAD>
<BODY>
<FORM id=f1>
User ID : <input type=text name=id></input><br>
Password :<input type=password name=pw></input><br>
E-mail :<input type = text VCARD_NAME = "vCard.Email"> <br>
<input type=button value=submit onclick="subForm()">
</FORM>
</BODY>
</HTML>
From: http://support.microsoft.com/kb/329156
Use this Method:
AutoCompleteSaveForm = function(form){
var iframe = document.createElement('iframe');
iframe.name = 'uniqu_asdfaf';
iframe.style.cssText = 'position:absolute; height:1px; top:-100px; left:-100px';
document.body.appendChild(iframe);
var oldTarget = form.target;
var oldAction = form.action;
form.target = 'uniqu_asdfaf';
form.action = '/favicon.ico';
form.submit();
setTimeout(function(){
form.target = oldTarget;
form.action = oldAction;
document.body.removeChild(iframe);
});
}
Tested with ie10, ff latest, chrome latest

Have you try the answer of my question that you mention?
The answer is using hidden iframe but seems he claim the idea is not working on IE and Chrome on that time.
Try to take the idea, and instead of using hidden iframe, just put the username/password/submit visible input element in a form POST, in an iframe. So user will enter login details directly into iframe. With proper Javascript you can put loading image, get success or denied from server and update the parent or the whole page. I believe it should work on any browser.
Or if you still want to use AJAX since you probably implemented the API on server side. You can make the iframe to just send a dummy POST at the same time send the real user/pass to AJAX URL.
Or back to use hidden iframe, not to hide it but move it to the invisible area like top: -1000px.
After several hours searching, I found a solution at Trigger autocomplete without submitting a form.
Basically, it uses a hidden iframe in the same page, set the action of your form to the 'src' of the iframe, and add a hidden submit button inside the form, when user clicks your button which triggers AJAX requests, you should programmatically click the hidden button before sending the AJAX request. see example below:
In your form page:
<iframe id="hidden_iframe" name="hidden_iframe" class="hidden" src="/content/blank"></iframe>
<form target="hidden_iframe" method="post" action="/content/blank" class="form-horizontal">
<input type="text" name="name">
<input type="text" name="age">
....
<button id="submit_button" type="submit" class="hidden"></button>
<button id="go_button" type="submit" class="hidden">Go</button>
</form>
Then java script:
$('#go_button').click(function(event){
//submit the form to the hidden iframe
$('#submit_button').click();
//do your business here
$.ajax(function(){
//whatever you want here
}})
);
Hope this helps.
