.click() not working in iframe in ie - javascript

My project is an asp.net project and i have a separate page named "Districting", and it's called from an iframe.
In Districting.aspx page, there is a function that fires a .click() event for a button:
The button clicked by the user:
<button id="b1" onclick="DoneClicked();">Done</button>
The function is:
function DoneClicked(){
$("#button1").click();
}
button1 is the id of an asp button, which calls a function from the server side:
<asp:Button id="button1" cssClass="invisiblebutton" OnClick="AddingDistrict" runat="server" />
The cssClass, invisiblebutton contains the property: display:none.
The problem is that $("#button1").click() event is not working only in IE, so it's not calling the function AddingDistrict() from cs page.
It is working fine in chrome and FireFox.
Can anyone help me about this issue?
Thanks in advance:)

Perhaps javascript in ie is disabled
check it

how to open an aspx page as popup on button click

I have created an aspx page "Analyse.aspx", I want to pass an argument to this page when calling it on a button click of another page say 'Master.aspx' by-
OnClientClick="javascript:window.open('Analyse.aspx?Param=');"
how to do it?
"Could not load type" can happen due to various reasons and not because of popup. Try to call Analyse.aspx directly in your browser and make sure it works. To troubleshoot read Parser Error Message: Could not load type 'webmarketing'
UPDATE
Your code is not well formed.
Instead of
OnClick="javascript:window.open(Analyse.aspx?Param=""');"
must be
OnClick="javascript:window.open('Analyse.aspx?Param=');"
UPDATE #2
To wire a js code to js onclick event you should use the OnClientClick() event
<asp:Button ID="btnDeDupCheck" runat="server"
OnClientClick="javascript:window.open('PieChart.aspx?Param=');"
Text="De-Duplication Check" Visible="False" />
The OnClick() event is used to run a .net code.
UPDATE #3
To add values from asp.net controls you need to inject asp.net code. Read How to pass a value into a javascript function within an aspx page onClientClick or OnClientClick Javascript:confirm get value in textbox?
<asp:Button ID="btnDeDupCheck" runat="server"
OnClientClick="javascript:window.open('PieChart.aspx?Param=<%=txt1.ClientID%>');"
Text="De-Duplication Check" Visible="False" />
I finally got the it,successful executed code-
OnClientClick="javascript:window.open('Analyse.aspx?Param=');"
but my new query is how to pass parameter from current page to this new page 'Analyse.aspx',
say my parameter is - "txtPwd.text"
and how to catch the argument on pageload of Analyse.aspx

Calling c# from JS via button

So what I want to do is click on a button which will cause JS code to run which will cause another button to click and button #2 will be runat="server" and cause a C# function to run onClick.
But using the below does not cause the C# function to run even though simply clicking the button2 does cause it to run.
function button1_click() {
document.getElementById('button2').click();
__doPostBack('#button2', 'onclick');
$('#button2').trigger('click');
// neither worked (tried them seperately)
}
<asp:Button runat="server" Visible="true" text="you should not see this" ClientIDMode="Static" ID="button2" onclick="button2_Click" formnovalidate />
Useful knowledge:
- button one is in a client form
- button two is in a runat="server" form
This code
$('#button2').trigger('click');
should work.
Have you checked that the ID 'button2' is not changed during runtime?
Sometimes, when using master pages or user controls, the client ID of an element with runat="server" attribute will get a prefix at run time.
Use a debug console (depends on your browser, try pressing F12) to check the effective client ID.
Also, have you checked that button1_click() function is actually called?

Unable to make ASP.NET control button fade out with JQuery

I have a simple enough problem: I have an ASP.NET control button and I want to make it fade out and then call some function (such as an alert) using JQuery. Here is what I have so far:
ASP Code for the Button:
<div id="begin">
<span id="startButtonSpan">
<asp:Button ID="startButton" class="startButton" runat="server" Text="Click Me!" OnClientClick="startButtonClick()"/>
</span>
</div>
JavaScript:
function startButtonClick()
{
$("#startButtonSpan > input").fadeOut(500, callAlert());
}
function callAlert()
{
alert("Made it here...");
}
When I click the button, the alert displays but the page does not even seem to try to perform the fadeOut. When I close the alert, the button is still there, staring at me.
Can anyone see any mistakes or does anyone have any suggestions on how I might be able to achieve the intended goal of fading out my button? Fadeout is really just my way of testing whether I can manipulate ASP controls using jQuery, so more than just the simple fadeOut, this is me trying to learn how to do that.
I tried a slightly more simple jQuery call using the code below, but it does not seem to work either:
ASP Portion:
<div id="begin">
<span id="startButtonSpan">
<asp:Button ID="startButton" class="startButton" runat="server" Text="Click Me!" OnClientClick="startButtonClick()"/>
</span>
</div>
<div id="jQueryTest" style="display:none;">
Block for testing jQuery.
<h1 id="testMessage">Child element for the ASP div.</h1>
</div>
Javascript Portion:
function startButtonClick()
{
$("#jQueryTest").css("display", "block");
$("#jQueryTest").show();
}
For this example, the text does display, but it immediately disappears again.
Any help or suggestions as to what I might be doing wrong would be greatly appreciated.
Use the class as a selector $('.startButton') instead of the ID since ASP.Net controls change their IDs dynamically when rendered by appending its Page & Control information.
$(".startButton").fadeOut(500, callAlert);
Or, if you're adamant about using the ID, here is another way to handling the selector,
$("#<%=startButton.ClientID %>")
Or, as Jacob suggested in his answer, you could ClientIDMode="Static", but this works only if your application is .Net 4.0 or above.
Also, use CssClass instead of class
<asp:Button ID="startButton" Csslass="startButton" runat="server" Text="Click Me!" />
The first example has 2 problems.
1. You should write
$("#startButton").fadeOut(500, callAlert);
and not
$("#startButton").fadeOut(500, callAlert());
2. For ASP.NET you must set ClientIDMode="Static" ortherwise asp.net will alter your id.
<asp:Button ID="startButton" ClientIDMode="Static" ... OnClientClick="startButtonClick()"/>
How about the fact that your code is fine (although other answers here should be considered) but your button is making a post back to the server and simply your browser does not have enough time to render the fade effect.
To test this, add a return false; to the OnClientClick property. This will of course cancel your action on the server but you will obtain the fade effect:
<asp: Button ... OnClientClick="startButtonClick();return false;"></asp:Button>
To work around this and still submit your request, you can try to use the ASP.NET __doPostBack method in JavaScript
ASP.NET:
<asp:Button ID="startButton" class="startButton" runat="server" Text="Click Me!" OnClientClick="startButtonClick(this);return false;"/>
JavaScript:
function startButtonClick(button)
{
$("#startButtonSpan > input").fadeOut(500, function(){__doPostBack(button.name, "")});
}
The __doPostBack method takes two arguments: the name of the control that is doing the postback and a postback argument that can be use to send more info on the server. In the case of the asp:Button, the name of the button should be sufficient to send the request without a problem.
Using this technique you will fade the button on the client and also trigger the action on the server. I cannot guarantee that this exact code will work (I don't have access to a dev environment right now) but you should get the idea.
If I could, I would like to provide another answer for those that use MasterPages and find that you can't always use $("#<%= SomeContentControl.ClientID %>") when working with Content controls.
What I do is set the MasterPage ID in my Init() like this:
protected void Page_Init( object sender, EventArgs e )
{
// this must be done in Page_Init or the controls
// will still use "ctl00_xxx", instead of "Mstr_xxx"
this.ID = "Mstr";
}
Then, you can do something like this with your jQuery:
var masterId = "Mstr",
$startButton = getContentControl("startButton"),
$message = $("#jQueryTest");
function getContentControl( ctrlId )
{
return $("#" + masterId + "_" + ctrlId);
}
function hideStartButton()
{
$startButton
.stop(true, true)
.fadeOut("slow", showMessage);
}
function showMessage()
{
$message
.stop(true, true)
.fadeIn("slow");
}
$startButton.on("click", hideStartButton);
Here is a jsFiddle that has the Mstr_ prefix already inserted as if ASP.NET rendered it.

Firefox HTTP Form Action doesn't fire

In Chrome and IE, the following code, when the Anchor tag is clicked, pops up the form (modal box ID of "modalContent", form ID of "DL") and adds an "OnSubmit" to the Form. When the Form is submitted, it will navigate to the requested PDF via Javascript, and run some ASP to send an email with their details attached.
<script language="javascript">
function downloadAnyway(link) {
$('#DL')[0].setAttribute('ONSUBMIT', 'return checkform("' + link + '")');
$('#modalContent').modal();
}
function checkform(navName) {
window.open(navName);
$.modal.close();
}
</script>
<!-- link to download a product guide -->
Product Guide
<div id="modalContent">
<form id="DL" action="contactusprocessNew2.asp" method="post" name="contact" >
<div align="center">
<input type="image" src="templates/default/images/submit_download.gif" class="imagebutton" value="submit" />
</div>
</form>
</div>
This works fine in IE and Chrome, in Firefox, the Javascript onsubmit works, but the action of the asp never fires. If I remove the javascript, the asp fires as expected.
So, the final form in FireFox, after the "onsubmit" has been dynamically added looks as below:
<form id="DL" action="contactusprocessNew2.asp" method="post" name="contact" onsubmit="return checkform("downloads/ProductGuide.pdf")">
The onsubmit fires, opening the product guide in another tab, however, the ASP Action never fires. There is more that goes on here, like we write a cookie making sure we don't ask the client for a download every time they use our downloads, however, I've trimmed off anything I think is outside the problem domain.
In the asp, I have gotten rid of all code and put a simple response.redirect to see if it fires and make sure nothing is going on in the ASP.
Any idea how I can get this to function in FireFox?
UPDATE:
I have replaced the onsubmit event wireup with a 'proper' jquery submit wireup replacing the first line below, with the second. The asp on the form still does not function.
//$('#DL')[0].setAttribute('ONSUBMIT', 'return checkform(\'' + link + '\')');
$('#DL').submit(function checkform() {
$.modal.close();
window.open(link);
return true;
});
UPDATE 2
Right, it is because to modal popup CLOSES before the ASP fires. If we comment out the line $.modal.close(); then the asp fires as expected. In Chrome and IE the javascript and the ASP must fire at the same time, in Firefox, the javascript fires which "hides" the div with the "modelContent" and the asp can no longer fire. So this is the real problem... now how to sort it out...

href link to trigger asp.net c# button event

I have a navigation bar consisting of list items. Right at the end of the nav bar I want a logout link:
//other links
...
<li>
logout
</li>
I have an event in my C# code called Logout_Click(object sender, EventArgs e) that I want to run when the user clicks the above navbar link, but obviously ordinary <a> tags don't trigger ASP.NET click events.
So I thought I'd be clever and create a HIDDEN <asp:Button> called logout that does trigger the Logout_Click function, and then get the JavaScript to click the button for me.. here is my code:
Log Out
<form runat="server">
<asp:Button ID="logout" runat="server" onclick="Logout_Click" Visible="false" />
</form>
But it still didn't work.
Can someone help me?
Try:
Log Out
Can you try without the Visible="false" on the asp:button?
And if it works hide it with css instead, style="display:none;"
I think the script needs the client side id of your asp.net control:
javascript:document.getElementById('<%=logout.ClientID').click()
Or you can use the __doPostBack function ...

Why not you are using Asp.net LinkButton ?
It's easy to do this work with LinkButton.
