I have a page which uses dijit/form/Form to validate all of the form widgets in it.
Validation works correctly if I put widgets directly under the Form (tag).
Once I surround the widgets with a dojox/mvc/Group (within the form), Form validation stops completely and none of the widgets seem to validate when I call Form::validate().
Debugging the Dojo code shows that nested widgets are never considered validatable in the Form so when I surround widgets with Group they get excluded from validation.
Is there a workaround for this?
AFAICT from dijit/form/_FormMixin#_getDescendantFormWidgets() and dijit/_WidgetBase#getChildren(), the issue can be solved by adding data-dojo-mixins="dijit/_Container" to the element having data-dojo-type="dojox/mvc/Group".
Also (though I'm not sure if it meets your requirement), dojox/mvc/tests/test_mvc_new_loan-stateful.html example shows form validation solution with dojox/mvc.
Hope it helps.
Best, Akira
It seems like there is no easy way to solve this with dijit/form/Form. At the very least, it should be subclassed or monkey-patched to make it consider nested widgets.
However, it seems that dojox/form/Manager handles nested widgets properly, so I have switched to it.
Switching to Manager required some refactoring since it cannot be simply converted into an object with dom-form (dijit/form/Form can be converted).
HTML code before:
<div
id="_pg_detailForm"
data-dojo-type="dijit/form/Form"
encType="multipart/form-data"
action="" method=""
>
... form widgets (surrounded with MVC Groups...etc)
</div>
After:
<form id="_pg_detailForm">
<div
id="_pg_detailFormManager"
data-dojo-type="dojox/form/Manager"
>
... form widgets (surrounded with MVC Groups...etc)
</div>
</form>
I am trying to use a kendo numeric text box with angular validation (ng-required) however I'm not able to get it working. The ng-required attribute on this element has no effect on the form validation status.
From my understanding, the reason why this doesn't work is because kendo numeric text box uses k-ng-model to store it's value, whereas the angular validation works only with ng-model.
Has anyone else seen this issue, are there any workarounds?
I have found a workaround that involves using the kendo-numeric-text-box along with a hidden input field which makes use of ng-model.
<input data-kendo-numeric-text-box data-k-ng-model="numValue"/>
<input type="hidden" data-ng-model="numValue" data-ng-required="true" />
I have trouble using spring mvc checkbox tag. I have a BookmarkMapping object which in turn has List object. Inside Folder Mapping there are three attributes like id, name and isMapped (boolean). It is this isMapped property based on which I intend to show the checkbox.
So in my page I get modelAttribute as 'bookmarkMapping'. inside which there is a list of folderMapping. Each of the item inside folderMapping is isMapped set as true or false for my checkbox checked attribute.
I am trying this
<c:forEach var="folderMapping" items="${bookmarkMapping.folderMapping}" varStatus="i">
<form:checkbox path="folderMapping[${i.count-1}].isMapped" label="${folderMapping.folderName}"/>
</c:forEach>
This displays the checkboxes fine in html but when posted it is nor reflecting changes of checkboxes as true /false in posted objects. It always shows false.
Set the value attribute of the checkbox tag.
<c:forEach var="folderMapping" items="${bookmarkMapping.folderMapping}" varStatus="i">
<form:checkbox path="folderMapping[${i.count-1}].isMapped"
value = "${folderMapping[${i.count-1}].isMapped}"
label="${folderMapping.folderName}"/>
</c:forEach>
Have you tried the <form:checkboxes /> tag? I think this is what you need here, maybe could solve your problem. Try something like this, replacing your <c:forEach /> tag:
<form:checkboxes path="folderMapping" items="${allCheckboxValues}" itemLabel="folderName" itemValue="isMapped"/>
You need to prepopulate allCheckboxValues in your controller with all possible values.
Check out spring documentation about this tag for more help and the TLD documentation.
i have a form with 2 buttons let say A & B.
The required fields are depending on the button pressed.
Im using actually a DataBinder allowing me to specify requiredFields but for all actions.
How can i customize the required fields that will be depending on the button pressed ?
Thanks in advance
If you use <input type="submit" name="button1" value="Click me!" /> you can check for that button1 value in your form and then use different validation rules within your validator. You just have to extend your binding model according to these button names and to give your two buttons different names. Note that this doesn't work with <button type="submit"> in most IE versions and therefor input[type=submit] is the better choice here :-)
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.
