i'm trying to upload a file trough iframe.
i create the iframe in this way:
<iframe frameBorder="0" height="50px" width="100%" id="iframe-upload"/>
after this i append the iframe to the DOM:
$('#iframe-upload').contents().find('body').append('<form method="post" action="admin/images/upload" enctype="multipart/form-data" id="form-upload-image"><input name="data[image]" type="file" id="image-upload" /><input type="button" id="btn"></form>').appendTo("#formupload");
to submit i act like this:
$("#iframe-upload").contents().find('#btn').bind('click', function(){
$("#iframe-upload").contents().find('#form-upload-image').submit()
})
now, i cannot figure out WHEN i have to call:
console.log($("#iframe-upload").contents());
to get the content.
The problem is sync between my contents() request and iframe refresh, actually jquery goes first, and AFTER the iframe refreshes. In this way i cannot reach the real response.
p.s.
i've tried live(), on(), change() con the frame content, but all these events fires up only one time ( when i select the file before submitting the form ) and so are useless
thank you in advice
You should be able to grab the contents from the iframe before submitting the form. To achieve this, you can bind a function to the form's onSubmit event.
$('#form-upload-image').bind('submit', function (event) {
event.preventDefault();
console.log($("#iframe-upload").contents());
this.submit();
});
or possibly
$('#form-upload-image').submit( function () {
console.log($("#iframe-upload").contents());
});
This is just off the top of my head.
Check the contents after the iframe is loaded.
$('#iframe').load(function () {
$(this).contents();
});

Hi I am printing the ajax html response to div element and giving radio input option to select the file. after selecting the specific file the another div should show the message. but the ajax html response is not working
Jquery script:
$(document).ready(function()
{
$('#upload').ajaxForm({
beforeSubmit: function() {
$('#Analysis').show();
$('#Content_column').hide();
$('#file_list').show();
$('#trait').show();
$('#trait').html('Submitting...');
},
success: function(data) {
var $out = $('#file_list');
$out.html('       File list:');
$out.append('<div id="list">');
$('#list').html(data);
$out.append('</div>');
}
});
});
The output of this script is
<ul class="php-file-tree"><li class="pft-directory">Genotypic<ul><input id="Penotypic" type="radio" name="uploads/Genotypic/" value="uploads/Genotypic/jquery.txt" />jquery.txt<br><input id="Penotypic" type="radio" name="uploads/Genotypic/" value="uploads/Genotypic/marker.csv" />marker.csv<br></ul></li><li class="pft-directory">Other</li><li class="pft-directory">Penotypic<ul><input id="Penotypic" type="radio" name="uploads/Penotypic/" value="uploads/Penotypic/namPheno.csv" />namPheno.csv<br><input id="Penotypic" type="radio" name="uploads/Penotypic/" value="uploads/Penotypic/perl.pl" />perl.pl<br></ul></li></ul>
Jquery script:
$('#Penotypic').click(function() {
var $out1 = $('#trait');
$('#trait').show();
$out1.append('Submitted...');
});
this is not showing anything in the div trait. may be the html response is loading as a tesxt so the #Penotypic is not recognised. please help me to fix this.
Thanku
You have many inputs of id="Penotypic". Make every id unique or use classes as function trigger.
I wouldn't use "/" in the name attribute. See: http://www.w3.org/TR/html401/types.html#type-name
Then try if your ajax script does work. If it doesn't work, try if it works from static page (don't use your first jQuery script, but it's output as a static form). You probably need to bind your event trigger. Use jQuery's on().
I have a Razor/ASP/MVC3 web application with a form and a Submit button, which results in some action on the server and then posts back to the form. There is often some delay, and it's important that users know they should wait for it to complete and confirm before closing the page or doing other things on the site, because it seems users are doing that and sometimes their work has not been processed when they assume it has.
So, I added a "Saving, Please Wait..." spinner in a hidden Div that becomes visible when they press the Submit button, which works very nicely, but I haven't been able to find a way to get the Div re-hidden when the action is complete.
My spinner Div is:
<div id="hahuloading" runat="server">
<div id="hahuloadingcontent">
<p id="hahuloadingspinner">
Saving, Please Wait...<br />
<img src="../../Content/Images/progSpin.gif" />
</p>
</div>
</div>
Its CSS is:
#hahuloading
{
display:none;
background:rgba(255,255,255,0.8);
z-index:1000;
}
I get the "please wait" spinner to appear in a JS method for the visible button, which calls the actual submit button like this:
$(document).ready(function () {
$("#submitVisibleButton").click(function () {
$(this).prop('disabled', true);
$("#myUserMessage").html("Saving...");
$("#myUserMessage").show();
$("#hahuloading").show();
document.getElementById("submitHiddenButton").click();
});
});
And my view model code gets called, does things, and returns a string which sets the usermessage content which shows up fine, but when I tried doing some code in examples I saw such as:
// Re-hide the spinner:
Response.write (hahuloading.Attributes.Add("style", "visibility:hiddden"));
It tells me "hahuloading does not exist in the current context".
Is there some way I am supposed to define a variable in the view model which will correspond to the Div in a way that I can set its visibility back from the server's action handler?
Or, can I make the div display conditional on some value, in a way that will work when the page returns from the action?
Or, in any way, could anyone help me figure out how to get my div re-hidden after the server action completes?
Thanks!
Is this done with ajax? I would assume so because the page is not being redirected. Try this:
$(document).ready(function () {
$("#submitVisibleButton").click(function () {
$(this).prop('disabled', true);
$("#myUserMessage").html("Saving...");
$("#myUserMessage").show();
$("#hahuloading").show();
document.getElementById("submitHiddenButton").click();
});
$("#hahuloading").ajaxStop(function () {
$(this).hide();
});
});
As an aside, you no longer need runat=server.
Is there a JQuery plugin that allows me to 'unhide' a form by after clicking a link? Like I have an invite link that can take me to a one text field form for an email address but I want this form to just drop down (pushing the rest of the content down also) and shows the form to submit the email. If you guys can think of a JQuery plugin that lets me do this, please let me know
Edit:
So I did this
<div class='add-link'>
<div id='invite_link'><a href=''>Invite User</a></div>
<div id='invitation_form'>
<form>
<input type='text'/>
</form>
</div>
</div>
and my jquery looks like
<script type="text/javascript">
$(function()
{
$("table").tablesorter({sortList:[[0,0],[2,1]], widgets: ['zebra']});
$('#invitation_form').hide();
}
);
$('#invite_link').click(function() {
$('#invitation_form').slideDown();
});
Do you guys see any error that causes the form not to slide down. It hides the form when the page loads but when I click the link it is not sliding down.
$('a.mylink').click(function() {
$('#MyForm').slideDown();
});
I don't think you need a jQuery plugin for this. The base jQuery library should be sufficient.
$('#showFormLink').click(function () {
$('#form').slideDown();
});
If you're looking for animation, that's possible as well by passing in a duration argument to slideDown.
Take a look at the jQuery show documentation.
I am using an iFrame with a form that return some content with an AJAX link.
I am then moving the returned content out of the iFrame into the main page.
However, then the ajax link does not work and the error "Element is null" is created once the link is clicked.
How can I move content from the iFrame and still have the AJAX link working?
Here's the code returned by the iFrame:
<span id="top">
<a id="link8" onclick=" event.returnValue = false; return false;" href="/item_pictures/delete/7">
<img src="/img/delete.bmp"/>
</a>
<script type="text/javascript">
parent.Event.observe('link8', 'click', function(event) {
new Ajax.Updater('top','/item_pictures/delete/3', {
asynchronous:true, evalScripts:true,
onCreate:function(request, xhr) {
document.getElementById("top").innerHTML = "<img src=\"/img/spinner_small.gif\">";
},
requestHeaders:['X-Update', 'top']
})
}, false);
</script>
</span>
I see two problems with your code.
First the solution (I think :-))
When your iframe loads, the javascript in it runs. Javascript attaches an observer to parent document's link8.
Inside the observer you define another function (onCreate). This function will run in iframe context, making document object refer to iframe and not to main document. When you remove link8 from iframe to move it to main document, document.getElementById("top") will become null - hence error.
Perhaps change it to:
parent.document.getElementById("top").innerHTML = "<img src=\"/img/spinner_small.gif\">";
Second problem (that is not really a problem in this particular case) is, if you move whole span (including the script) to main document, the javascript will run again in main document's context. In your case, you should see an error or warning after you move the content, stating that parent is null (or similar).
To remove the second problem, return your iframe data in two divs or similar. Then copy only div with html to main document.
What I did was move the AJAX call out to an external js file and called the function once the link was clicked. It works now.
I am using JQuery with Boxy plugin.
When a user clicks on a link on one page, I call Boxy.load to load a form onto the pop-up. The form loads and is displayed inside the pop-up without problems.
However, I can't bind the form to a submit event, since I can't select the form element.
This is the event handler:
$('#flag-link a.unflagged').click (function(e) {
url = $(e.target).attr('href');
Boxy.load(url, {behaviours: function(r) {
alert ($("#flag-form").attr('id'));
}
});
});
The alert reads "undefined" when it is displayed.
And this is the form:
<form id="flag-form" method="POST" action="somepage">
<table>
<tr><td><input type="text" name = "name"></td></tr>
<tr><td><input type="submit" value="OK"></td></tr>
</table>
</form>
What am I doing wrong?
First (a minor point, but a potential source of trouble), it should be id="flag-form" not id = "flag-form" (no spaces).
Second, you shouldn't need r.find(). Just do $("#flag-form").attr("id")
As far as I understand, live() method must be used to bind an element to an event in this case:
$("#flag-form").live("submit", function(){ ... }
Presently, live method is documented to be not supporting the submit event. However, I could work it out with Chrome and FF. On the other hand, I couldn't get it working in IE. A better way for cross-browser compatibility seems to be binding the submit button of the form to the click event.
$("#flag-form-submit").live("click", function(){
I learnt that declaring methods in behaviours: function (e) {} works, in addition to using live() methods.
E.g.:
$('#flag-link a.unflagged').click (function() {
Boxy.load(this.href, {
behaviours: function(r) {
r.find('#flag-form').bind('submit', function() {
// do on submit e.g. ajax calls etc.
});
}
});
return false;
});
Boxy opens the URL (url = $(e.target).attr('href');) in an iframe. So you cannot find the form from the opening page(parent page). Your code to bind the form should be in the child page (ie, the Boxy iframe). You can check the iframe URL using your code, url = $(e.target).attr('href');
