How To Call The Text_changed Event From Javascript
Jul 23, 2005
I ve a aspx page with a textbox.I have created the Text_Changed event
for this textbox.We know that , this will be fired when we enter any
text in that textbox and pressing the enter key.quite natural.
I am putting some text in that text box thru javascript from the
window_onfocus event.
After that , i need that the text_changed(server event) event to be
fired,so that i could perform some search operation.
Could you please tell me how can i call the Text_changed server event
from the javascript.

I need to make a $.post call on the beforeSend event of another $.ajax call.I read the documentation and I see that if the beforeSend return false the ajax call will be interrupt.So I made this code but doesn't work, because the real value of the beforesend function isn't true or false, is the value of the post.I have to do this because when you click on a link I need to verify before if you are able to do this via db permission of my webapp.I think you don't understand...This is the code:
$.ajax({
async: true,
beforeSend: function(){[code]....
});I see always the alert of success event, so the return of the beforesend is not correctly done.

I'm currently facing a weird issue with the onchange event. I have a web application where each blur event makes a call the webserver to store the value of the textfield. I only want to trigger that ajax call when something has changed, so i track the onchange event on each textfield to set a flag if something has changed.
The onchange event always fires to first time when i click outside of a textfield even if i didn't change anything in the field.
I narrowed it down to the following: A prefilled textfield always fires the onchange-event the first time you leave the textfield. An initially empty textfield does not fire the onchange event.
Sample code (IE 8 on Windows 7 computer):
script:
HTML:

I have a small portal website with some ads around. I'm in the process of creating an ads manager script with php and mysql and would like to know when an ad was clicked. I'm confused on how to do this but, the only way I can think of is by adding an onclick even to every ad img:
HTML Code:
<a onclick="callfunction('ad_id');" href="ad url"><img src="path"></a>
Now, how would I call a php function with onclick? I guess that can be done with ajax but, don't know much on how to use it?

I've got a script which is called by a keypress event, something like this:
<html>
<head>
<script type="text/javascript">
function respondToKey(e) {
keyPressed = String.fromCharCode(e.which);
if(keyPressed == 'g'){
alert('you pressed the g key');
window.open('http://google.com');
}
}
</script>
<title>Untitled</title>
</head>
<body onkeypress="respondToKey(event)">
hit the g key to open a google window
</body>
</html>
when you hit the right key, the alert appears, but the window.open() never happens. There's not even a message in the Error Console, just nothing.
Is this a security feature? Any way I can get around it? And, if it's a security feature, is the fact that it fails silently with no error message also a security feature? Because it's rather annoying.

I have an html input and when a button is clicked, that input's value is passed to a function. However, the value becomes undefined when execution gets inside the function despite NOT being undefined inside the event handler! See below code...

So I have a basic REST call to Flickr's API. This is how I'm displaying the images.
$("#flickr").append("<img src = '"+ photoURL +"' class='thumbnail' />");
Then I have this later on in the same file...
$(".thumbnail", this).bind("click", function(){
$("#display").html("<p>clicked</p>");
});
For some reason, it will not detect this selector. I've also tried $("#flickr > img") & $("img"). None of these selectors seem to trigger this event. I tested $("#flickr").bind()... and I got the expected result, so I am pretty certain it is the selector that is not working. I have done a basic "thumbnail / enlarge" model a number of times from hard coded image tags to ajax sources, but never from Flickr's API.

I have a jQuery UI slider plugin working to scroll some content. I would like to add a mousewheel event. I have this installed and have it working with a small hack. My questions is, is it possible to have the mousewheel call the event on the slider? This way, when you move it with the mousewheel, it just moves the slider which will scroll the content.

First let me describe the problem. I have an HTML form that in one
field has an onBlur call to a JavaScript function. When you exit the
field, it calls the JavaScript routine, which in turn calls a PHP
script. The PHP script runs returns the value needed. And returns to
the JavaScript. The JavaScript function is then supposed to set
alerts depending on the values returned from the PHP script. It
doesn't. If you then move the cursor into the field and exit again,
it again runs the JavaScript which calls the PHP script then
proceeds to show the alerts exactly like it is supposed to.
I did some experimenting, and if you use a button to run the
JavaScript, the exact same thing happens. Click the button and the
PHP script sends back the value, but no alert. You click the button
a second time, and the alert shows.
I am using the JavaScript monitor in FireFox v1.5 so I can see that
the PHP script is being called and returning the correct value the
first time. So what I am trying to figure out is why the routine has
to be called twice before I get my alert.
Below is the HTML, JavaScript & PHP that I am using....

Is it possible to set an html element's (created through HTML DOM's createElement() method) 'onclick' attribute's value to a Javascript function which requires a parameter, passing a variable to it at the same time?
I have the following Javascript code:
var parentDiv = document.getElementById("subscribers");
var stubSpan = document.createElement("span");
stubSpan.id = "opentok_subscriber_" + stream.streamId;
stubSpan.onclick = showStreamInFullScreenMode(stream);
parentDiv.appendChild(stubSpan);
'stream' in the bolded line is a parameter variable of the function that the above code is in, and I'm trying to pass it to another function using an onclick event.

I'm using a script (with inner HTML), to swap currencies. My onClick event calls two scripts to change the content of two cells. It works fine in IE, but Firefox... Nothing. I've run firebug, the error returned is "illegal character".

I have a few buttons on a page I'm developing and I want the onclick event to call a javascript function in an external file and execute it. I would like to be able to pass a parameter to that function and then either have the function take the user to a new URL or make changes to the webpage content.
Initially (just to test) I had inline javascript that caused an alert to popup. That worked fine. Next I took the inline code and put it in a function in an external javascript file that was referenced in the HTML:

I am trying to call a java method from within my Javascript, but cannot
seem to get it to work. All the examples I have found online and in
the forums are using Java applets. I have a method that I want to call
that does a search, and produces a message dialog displaying the
results. Also, the class file lives next to the html file. How would
I invoke this in my code? This is what I have now:
<script>
function searchStrings(){
Searcher.search();
}
</script>
<form>
<input type="button" value="Search" onclick=searchStrings()>
</form>

Does anyone know how you can test if an applet's method exists before you try and call it?
for example, if you don't have a JRE installed on your computer and try and access an applet method it shoots out a javascript error at you. I want to be able to test if the applet is operational basically before I try and use any of its methods.
