I am new to structs... I has an application in that there is drop down list with in a form like this..
<%#taglib uri="/WEB-INF/struts-html.tld" prefix="prefix1" %>
<prefix1:form action="formaction">
<prefix1:select property="choose">
<prefix1:option value="1">1</prefix1:option>
<prefix1:option value="2">2</prefix1:option>
<prefix1:option value="3">3</prefix1:option>
<prefix1:option value="4">4</prefix1:option>
</prefix1:select>
Now my problem is, i want to submit the form upon onchange() event instead of having a submit button. i.e, when ever a value from drop down list selected the form has to submit..
How can i do it??
Edit: As mentioned in Quentin comment, you shouldn't submit your form onchange of drop down selection. Read here
But if you still want to do it then, A simple javascript will do the trick, Provided javascript is allowed to use in your application.
Add a name to your form tag, <prefix1:form action="formaction" styleId="formAction">
Add below function inside <script> tag in your jsp
Add an onchange event handler to the select element, <prefix1:select property="choose" onchange="submitForm()">
function submitForm () {
document.getElementById("formAction").submit();
}
I got my solution..Its looks like this
<prefix1:form action="sample">
<prefix1:select property="choose" onchange="this.form.submit()">
<prefix1:option value="1">1</prefix1:option>
<prefix1:option value="2">2</prefix1:option>
<prefix1:option value="3">3</prefix1:option>
<prefix1:option value="4">4</prefix1:option>
</prefix1:select>
</prefix1:form>

How do I make an AJAX call or submit form in ATG. Here's the code I'm using:
document.getElementById("myP").style.visibility = "hidden";
Will this work in the sense of ATG?
For ajax calls, in applications like spring and standard J2EE, you do a GET or POST call using AJAX for the form's action URL.
In ATG, you dont have action URLs. Rather, you have bean references, somewhat like
<dsp:form id="myForm">
<dsp:input type="myField1" bean="ABCFormHandler.myField1" />
<dsp:input type="myField2" bean="ABCFormHandler.myField2" />
<dsp:input type="submit" bean="ABCFormHandler.myProcess" style="display:none"/>
<dsp:input type="button" id="formSubmitter" value="Submit"/>
</dsp:form>
Here, we have defined a method called handleMyProcess in the ABCFormHandler, which also contains the properties myField1 and myField2.
Notice that the form tag has the id "myForm".
Next, there are two fields viz. "myField1" and "myField2".
There is a submit button which is hidden, by setting the style to "display:none"
Lastly, we have a normal button, for which we have simply set an id called "formSubmitter".
Now, we will use this normal button to submit the form with id "myForm".
We just need to call the form's submit() method using jQuery, which can be done simply as:
$('#formSubmitter').on('click', function(){
$form = $('#myForm');
$form.submit();
});
Hope this helps!
I have read multiple posts on similar issue but did not work.
I have fixed footer buttons and facing issue in calling "Post" version Edit action in Project controller. Here is what I'm trying to do
Let me know if question needs further explaination.
(I tried using Ajax.ActionLink which is suggested in multiple posts too but did not work out.
Similar Question
Finally I managed to fix it by some workarounds. Posting solution here to help someone.
Like I said earlier, I tried using Ajax.ActionLink but I was not able to achieve the same. Instead I looked for Calling Form Submit action from outside of form that's what I actually need here.
Form: Name your Form something, say "editProjDetailsForm"
#using (Html.BeginForm(null, null, FormMethod.Post,
new { #class = "form-horizontal",
name = "editProjDetailsForm" }))
Footer: Call this method from the footer button.
<input type="button" onclick="document.editProjDetailsForm.submit();"
class="btn btn-primary"
value="Save Changes" />
I tried this one too in footer but it did not workout:
#Ajax.ActionLink("Save Changes", "Edit", new { id = Model.ProjectId },
new AjaxOptions { HttpMethod = "POST" })

Fix: Found that it is a known issue and there is one suggested solution but did not work out much for me (i.e. for Internet Explorer).
input type=submit and anchor button in btn-group appear as different sizes
Solution: add .btn { line-height:normal!important; } or if you want to do only for a specific button lets say the above input button then do this:
<input type="button" onclick="document.editProjDetailsForm.submit();"
class="btn btn-primary"
value="Save Changes"
style="line-height:normal!important;" />
Sorry but I am new to C# and ASP.NET and I saw alot of posts about this problem but I quite didn't get it. I am trying to understand how to pass a GET parameter to an action thru HTML.ActionLink:
here is the the URL:
http://localhost:36896/Movies/SearchIndex?searchString=the
and my CSHTML page should look like this:
<input type="Text" id="searchString" name="searchString" />
#Html.ActionLink("Search Existing", "SearchIndex", new { searchString = "the"})
this hard coded parameter "the" is actually working, but how can I select the input element with id=searchString, with something like document.getElementById("searchString").value
Thanks,
If the value you want to send as GET parameter is not known on the server you cannot use the Html.ActionLink helper to add it. You need to use javascript to manipulate the existing link and append the parameter.
It looks like you have an input field that contains a search string and you want to send the value entered in this field to the server. A better way to handle this scenario is to use an HTML form with method="GET" instead of an ActionLink. This way you don't need to use any javascript - it's part of the HTML specification:
#using (Html.BeginForm("SearchIndex", "Movies", FormMethod.Get))
{
#Html.EditorFor(x => x.SearchString)
<button type="submit">Search</button>
}
Now when you click on the Search button the value entered in the SearchString field will automatically be sent to the SearchIndex action:
http://localhost:36896/Movies/SearchIndex?searchString=the
But if you absolutely insist on using an ActionLink you will have to write javascript to manipulate the href of the existing link when this link is clicked in order to append the value to the url. It's an approach I wouldn't recommend though because the HTML specification already provides you this functionality throughout HTML forms.
This makes the #Html.EditorFor refer to the Title field of the object, kinda in a random way but it works!
#using (Html.BeginForm ("SearchIndex", "Movies", FormMethod.Get))
{
#Html.EditorFor( x => x.ElementAt(0).Title)
<button type="submit">Search</button>
}
Still couldn't pass input parameter to the URL in the GET.
EDIT:
FINAL SOLUTION:
#Html.TextBox("SearchString")
<button type="submit">Filter</button>
and on the controller side, switch the input parameter. Basically it will automatically recognize the passed parameter.
public ActionResult SearchIndex(string searchString)
{
...
}
I want to show a popup dialog containing a dijit.ComboBox with data populated using ajax request or data store.
The problem I am facing is that the combobox is always disabled.
My selected code is:
<div dojoType="dojo.data.ItemFileReadStore" id="osTypeStore" data-dojo-id="osTypeStore" url="/AjaxPopulateOS.json">
</div>
<select id="osType" data-dojo-type="dijit.form.ComboBox"
data-dojo-props="
id:'osType',
store: osTypeStore,
placeHolder: 'Select a schdule type'" >
</select>
Any ideas
I believe it is because there are no items in it? Is it grayed out totally - and have the Disabled class parameter set?
Check that dijit.byId('osTypeStore') returns a store and that it has items in it.
If this is the case, change your code to
store: 'osTypeStore'
Note the quotes. This forces parser to evaluate the string into a dijit - and the store might not have been initialized correctly as a true variable at the point it is read. In other words, in combobox constructor - the javascript variable is undefined.
If this does not help, try forcing to set store after onShow has run for your dialog.
dialog.onShow = function() {
dijit.byId('osType').set('store', dijit.byId('osTypeStore'));
}
Try forcing it to enabled using the property of the combo
enabled: true,
Other than that, check it using Firebug or debug bar or something similar :)
I have a problem with this jQuery Change function:
<input type="radio" name="words" value="8" checked><span class="word">word1</span>
<input type="radio" name="words" value="6"><span class="word">word2</span>
$("input[#name='words']:checked").change(function(){
alert("test");
});
The problem is that the event gets only triggered when I click the first option (value=8) which is checked by default.
How Can I trigger the event when clicking any other option?
Please note: I have tried the above function on both Chrome and Firefox and I have the same problem.
Thanks!
should be $("input[name='words']").change(function(){
You are only binding the event handler to :checked elements. So as the first input has the checked property set, that's the only one that receives the event handler. Remove :checked and it should work fine:
$("input[name='words']").change(function(){
alert("test");
});
Here's a working example. Note that I've also removed the # character from your selector. You haven't needed it since like jQuery 1.2 or something like that.
$("input[#name='words']:checked").change(function(){
That finds all the input elements with the name words (actually, it won't work: the XPath-style # attribute selector has been removed since jQuery 1.3) that are checked and binds an event handler to them. If the elements are not checked when the selection is made, no event handlers will be bound to them.
The easiest solution is to bind to all relevant elements, and only fire code if they have been unchecked:
$('input[name="words"]').change(function() {
if (!this.checked) { // checkbox was checked, now is not
alert('unchecked');
}
});
working link
$("input[name='words']").change(function(){
alert("test");
});
$("input[#name='words']:checked").change(function(){
alert("test");
});
You've subscribed change function only to the radiobuttons whitch is checked (:checked). Remove it from selector.
$("input[name='words']").change(function(){
alert("test");
});
Code: http://jsfiddle.net/DRasw/1/
Give id property of Radio buttons
Add property of OnClick="CheckClick()" on second redio button.
In jquery CheckClick() function
if ($('#rb2').attr('checked')) {
alert('rb2 test');
}
