JavaScript - Problems With Changing Onclick Events On Buttons.

Is it possible to add an onclick event to an iframe or perhaps a DIV that holds an iframe?

In specific I am using the Facebook Open Graph like button:

Code:

<iframe src="http://www.facebook.com/plugins/like.php?layout=button_count&amp;show_faces=true&amp;width=450&amp;action=like&amp;colorscheme=light&amp;href=http://urltoshare.com/" scrolling="no" frameborder="0" allowTransparency="true" style="border:none; overflow:hidden; width:450px; height:21px"></iframe>

What I would like to do is add a simple onclick event to it so that I can run a process when the user clicks on it, at the moment I am just trying alert but cannot get it to work. By setting the iframe within a DIV with height/width specs set would an onclick event work within the DIV?

HTML TARGET:

Code:

<div id="login_link" style="margin-top:-142px;margin-left:245px;height:142px;">
		<img id="login_link" src="menu_button.png" /><a href="#"><img src="menu_button.png" /></a></div>
</div>

I'm trying to get menu_button.png to change to menu_button2.png on mouseover... I'd also like it to play a sound on click like "click.wav" I can't rename the div because it controls the slider

Heres my current project table:

http://bit.ly/dbwH23

I tried to put it in a span and have the span referance to the next tag but it didn't seem to work at least not in firefox. I'm going to keep lookin around but i'm not used to these types of code structure.

I was thinking of Embeding a flash file inside the div instead but that might be overkill. Anyone know of a solution that might work?

I am a Javascript newbie. I'm trying to code a page that has thumbnails of smaller images that when each image is clicked a larger image will load above the thumbnails, plus text within a div will change, plus more Javascript behind a shopping cart button will change. I'm not sure if this is even possible and have been searching and experimenting with the code without success.

To view the webpage I'm working on: http://toymakerpress.com/website/Fre.../TestPage.html

If you click on the dog image you can see where I'm headed (I also haven't had any luck loading the shopping cart button with it's unique Javascript code).

Here is my code so far:
The shopping cart button (I would like this code to swap out everytime I load a new image):
Code:

<a href="https://www.e-junkie.com/ecom/gb.php?c=cart&amp;i=A0085&amp;cl=82487&amp;ejc=2" rel="nofollow" target="ej_ejc" class="ec_ejc_thkbx" onclick="javascript:return EJEJC_lc(this);"><img src="../images/addtocart1.gif" border="0" alt="Add to Cart"/></a>

The code I'm working on for each thumbnail image:
Code:

<td><div align="center">
                  <a href="javascript:changeImage('../images/FreePlans/littledog-4Lg.jpg') "javascript:="javascript:"" onClick="load_content('orderform','more content') "><img src="../images/FreePlans/littledog-4.jpg" width="140" height="140" border="0" /></a></div></td>

Thanks!

I'm pretty new to Javascript and just started with some OOP concepts, so this might be an obvious one and I apologize if the question is much longer than it should be...

Basically I am trying to create a reusable class object with several internal functions, that is completely abstracted, meaning the class object itself should never have to reference the global declarations or window object. This class should be aware of itself at any point in the execution of it's own functions, and that is what I'm having trouble with at the moment.

What I'm trying to do is create reusable javascript "Apps" for my HTML web application, where multiple instances can be instantiated and used independently from one another.

My main problem is "this" loses context in the Ajax callback and onclick handlers. I'm not sure how to persist the context of "this", or at least keep a reference to prototype instance itself.

Let's set up a simple class called "App" to demonstrate what I mean...

Code:

var myApp = new App("MyFirstApp");

function App(argName) {
    this.name = argName;
    this.GetDirectory("C:\Program Files");
}

App.prototype.GetDirectory = function(argPath) {
    // "this" equals the App object instance (good!), meaning this.name should equal "MyFirstApp"
    Ajax.GetDirectory(argPath, this.GetDirectoryCallback, this.GetDirectoryTimeout, this.GetDirectoryError);
}

App.prototype.GetDirectoryCallback = function(argFilePaths) {
    // "this" equals the "window" object (bad!), meaning this.name should equal a null reference
    // argFilePaths contains a string of file paths (delimited using ;) returned by the server
    var mFilePaths = split(argFilePaths, ";");
    // for each file path, add a div to the document body containing that file path, with an onclick handler
    for (var i in mFilePaths) {
        var mFilePath = mFilePaths[i];
        var mFilePathDiv = document.createElement("div");
        mFilePathDiv.innerHTML = mFilePath;
        mFilePathDiv.setAttribute("onclick", "javascript:this.FilePathDivClickHandler();return false;");
        document.getElementById("body").appendChild(mFilePathDiv);
    }
}

App.prototype.FilePathDivClickHandler = function() {
    // I need a reference to the App object instance here, but I'm not sure where to grab it...
    // what I want to do is call GetDirectory again, referencing the div's innerHTML which contains another file path, like this:
    this.GetDirectory(event.target.innerHTML);
}

The onclick handler using "this" is obviously not going to work because "this" is a reference to the "window" object which does not have a function called FilePathDivClickHandler(). So what I can do is nest the GetDirectoryCallback() function inside the GetDirectory() function so that GetDirectoryCallback() can reference the variables in the outer function (GetDirectory).

Code:

App.prototype.GetDirectory = function(argPath) {
    // "this" equals the App object instance (good!), meaning this.name should equal "MyFirstApp"
    // "this" will still lose context inside the callback, so we can set up a variable called "instance" that the callback can reference
    var instance = this;
    Ajax.GetDirectory(argPath, GetDirectoryCallback, GetDirectoryTimeout, GetDirectoryError);
    function GetDirectoryCallback(argFilePaths) {
        // "this" equals the window object (bad!), meaning this.name should equal a null reference
        // "instance" equals the App object instance (good!), meaning instance.name should equal "MyFirstApp"
        // argFilePaths contains a string of file paths (delimited using ;) returned by the server
        var mFilePaths = split(argFilePaths, ";");
        // for each file path, add a div to the document body containing that file path, with an onclick handler
        for (var i in mFilePaths) {
            var mFilePath = mFilePaths[i];
            var mFilePathDiv = document.createElement("div");
            mFilePathDiv.innerHTML = mFilePath;
            mFilePathDiv.setAttribute("onclick", "javascript:instance.FilePathDivClickHandler();return false;");
            document.getElementById("body").appendChild(mFilePathDiv);
        }
    }
}

Even though we have persisted the App object instance through the use of the "instance" variable in the outer function, the onclick event handler still does not work; when it fires, "instance" is an unknown object.

Would placing the FilePathDivClickHandler() function inside the GetDirectory() function, much like what was done with the callback, allow me to use "instance" correctly for the onclick handler?

Hi,

I have a row of buttons that are made by innerhtml using this code:


Code:

 sidebar_html += '<div id="button"><input type="button" onclick="toggleRun('+poly_num+')" value="Start Bus" id="runBtn'+poly_num+'" style="width:120px; height:24px; text-align:center"></div><br />';

to fire this function:

Code:

function toggleRun(poly_num){
 var btn = document.getElementById('runBtn'+poly_num);
  if (document.getElementById('runBtn'+poly_num).onclick) {	
  if (run){
		run=false;
		document.getElementById('runBtn'+poly_num).value="Reload Page";
		startAnimation(poly_num);
		} else {
		run=true;
		document.getElementById('runBtn'+poly_num).value="Reload Page";
		window.location.reload();
		} 
}
}

the function can only run once, so the idea is that the button either runs it the first time or reloads the page.

at the moment, the way it's working is that the button that's clicked changes its value to "Reload Page" but the others keep their original value, even though it reloads if you click them.

So I'd like a way to change the value of the rest of the buttons when one is clicked. Is that possible?

Here's the page if I didn't explain myself well enough.

I'm trying to set up a post preview to use before submitting a post.

I need button 1 to open a pop-up with the preview of the post, and then button 2 should submit the post after the poster is satisfied.

With the code below, when either button is clicked, each work as expected.
The problem I'm having is, after the preview (OnButton1) is clicked, the submit button (OnButton2) will only open in a new tab, and not submit to the opened page from where it is being executed.
This could lead to many double posts, if someone who's not sure what is going on, keeps clicking the submit button.

I am wondering if there is a target "_self", or another method to make this work.
I'm very happy with the preview window popping up, as it should, but will try any suggestions that are offered.


function OnButton1()
{
var popUp = window.open ('','popUp','scrollbars=yes,resizable=yes,width=800, height=450');
document.form.action = "index.php?page=Preview"
document.form.target = "popUp"; // Open in a new window

document.form.preview(); // Submit the page

return true;
}
function OnButton2()
{
document.form.action = "index.php?page=post"
document.form.submit(); // Submit the page
return true;
}

I've got this script that spins an image for me but it dont stop spinning, in other words when i press startspinning with onclick it dont change it to stopspinning function it just keeps spinning, it works fine with href but not onclick.

Code:

function StartSpinning() {
		
		int = setInterval( 'SpinChange()', 100 );
		$( 'SpinButton' ).innerHTML = "Spinning (Click to Stop)";
		$( 'SpinButton' ).onclick = "StopSpinning();";
		Effect.Fade( 'turns', {duration: 0.3} );
	
	}
	
	function StopSpinning() {
		
		clearInterval( int );
		$( 'SpinButton' ).innerHTML = "Spin it";
		$( 'SpinButton' ).onclick = "StartSpinning();";
		UpdateFigure();
		Effect.Appear( 'turns', {duration: 0.3} );
	
	}

Can anyone help thanks.

If you wanted to change an ids onclick would int you just do this

document.getElementById("").onclick = "";

Is there a way to do it?

I'm doing a school project and I am using JPlayer as a media player. The site is essentially a music jukebox with a search. I have the playlist set up in the jukebox with 5 songs from the start, but I need to make it so that when you do a search and click the plus sign button next to a song, it will change one of the songs in the playlist to that song.

I have the search and everything working but when I click the button it does not actually change the variable in the javascript. Any help or insight to this would be much appreciated.

Below is the javascript (with some PHP, but that shouldn't effect what I need).

Thanks in advance!!

Also, the code for the playlist is in the myPlayList array, which I'm referencing the title, artist, and filename with the javascript values.

Hello,

I have a div called pageWrap to wrap my page with the css as
Code:

margin-top:-46px;

I would like to use Javascript onClick on another div.
This Div is called loginButton, the onclick should change the the css of pageWrap to 0px and onclick again should change it back.

If someone could help me with this code, it would be greatly appreciated

Thanks in advance!

Hey everyone - got a Q...

I'm having a tabbed panel where the 1st div is originally shown with display: block and the other 3 are display:none to hide, obviously. I want each div to have their own link where if you click the link for div 2 it hides the previous and shows that one etc. Here's what I originally have:

Code:

<script type="text/javascript">
function tab2() {
	document.getElementById('tab-content-2').style.display="block";
	document.getElementById('tab-content-1').style.display="none";
}
</script>

<div id="tab-top">
	<div class="tab-top-l">
	</div>

	<div class="tab-top-main">
		<ul>
			<a href="#" title="Lorem et"><li>Lorem et</li></a>
			<a href="#" title="Lorem et" onclick="tab2()"><li class="not-first">Lorem et</li></a>
			<a href="#" title="Lorem et"><li class="not-first">Lorem et</li></a>
			<a href="#" title="Lorem et"><li class="not-first">Lorem et</li></a>
		</ul>
	</div>
	<div class="tab-top-r">
	</div>
</div>

<div id="tab-content-1" style="display: block;">
	Content 1
</div>
<div id="tab-content-2" style="display: none;">
	Content 2
</div>
<div id="tab-content-3" style="display: none;">
	Content 3
</div>
<div id="tab-content-4" style="display: none;">
	Content 4
</div>

That successfully hides tab 1 and shows tab 2 but I don't know how to do it properly so it hides the previously shown one. One tab should always be shown.

Image attached to show what I mean.

Hello,
I am having problems trying to figure out how to do this.

Basically, we are using a turn-key software package to run a website, and this software has included the Highslide software for image viewing. Here is an example:

http://www.gem-tech.com/store/pc/vie...&idcategory=15

Notice the (3) images at the bottom. If you click one of them, the image will pop up and you can see the Highslide JS at work.

Problem is, the store owner wants to change up the buttons so they look more like this website:

http://morris-photographics.com/photography/

Off to the right corner, so they won't get in the way of the product, and the ability to put a description in is cool - that way when we have multiple types of similar products, we can label that particular photos to show what it is.

Would anybody be willing to assist on helping me get this setup? I have found some 'Highslide Configurators' online but Im very confused on the whole process

So here's my problem. I have a long list of buttons that I want to declare their onclick with values from an array. It looks something like this. It seems simple but obviously there's something that I'm not seeing that isn't allowing this to run.Here's what the code looks like


Code:

<html>
<body>
<form name="form1">
<input type="button" name="one">
<input type="button" name="two">
<input type="button" name="three">
</form>
<script>

function hello()
{
....
....
}

goodbye = ["one","two","three"]

for(i=0;i< 3; i++)
{
document.form1.goodbye[i].onclick=hello;
}

If anybody could help me out with this I would greatly appreciate it.

			document.write("<img src = 'Picture_' + CurrentPicture + '.jpg'/>")
