JavaScript - Alert() Changing Contents Of Array?

Hi guys I was wondering if its possible to add contents within a div to a javascript array. Something like this:
Code:

<script type="text/javascript">
function returnArray()
{
    var divContent   = document.getElementById('images');
    var matchImage = divContent.match(/<img/);
    /* add images into array somehow */
    alert('This is ' +ImageArray[1]);

}
</script>

<div id="images">
         <img src="image1.jpg" alt="image" />
         <img src="image2.jpg" alt="image" />
         <img src="image3.jpg" alt="image" />
</div>

Thanks for any info.

I was wondering if it is possible to put all the non null variables of an array into a string variable with spaces between each array value? For example, if array() is a text array and has 10 values, array(0) through array(9), with three of those values null, let's say array(3), array(5), and array(7) are null, is there a way to put the remaining seven values into a string variable with spaces between each array value?

Hi, i need to read a files contents to an array so that i can check which lines of the file i need to write back. im not very good with arrays and haven't had any luck so far.

thanks

Hi,

I'm doing some experimenting. So this may look bad to javascript experts here. But I'm trying to learn.

I have a header div that will show a larger image when the user mouses over each thumbnail image. I used jQuery to create this effect. The header div contains a button. Once the button is clicked, an alert will pop up to tell the user the artist's name of image. The button is wired to an ID of a paragraph. Problem is, my code is not working. I don't want to use "onclick" inline javascript (which is what I am using to call the showArtistname() function). I want unobtrusive javascript like jQuery is. I'm not sure how to do this. I don't know if I should use an array or if I'm even approaching this correctly. Well, it's not correct, because it's not working...

Here is my jQuery code:

Code:

$(function(){
$("a:has(img.small)").mouseover(function(){
var bigImage= $(this).attr("href");
$("#heading").attr({src: bigImage});
return false;
});

});

here is my javascript code:

Code:

function showArtistname(){ 

var a = document.getElementById("bluesails", "purplemountains", "bigsky", "nightlights", "fireysunset", "brilliantsunrise").innerHTML;


switch(a) {
	case "bluesails":
		alert("Arthur MacKenzie")
		break
	case "purplemountains":
		alert("Maggie Laing")
		break
		
	case "bigsky":
		alert("Arthur MacKenzie")
		break
		
	case "nightlights":
		alert("Aria Soriano")
		break
		
	case "fireysunset":
		alert("Felix Buckley")
		break
		
	case "brilliantsunrise":
		alert("Felix Buckley")
			
}
}

Here is the HTML:


Code:

<div class="container_12" id="_container">

  	<div class="grid_12" id="12_header" > 
    	
        <div class="hc_left_pic"> <images/01_md.jpg" id="heading" alt="Big Image." />
    <div id="showImage" onclick="showArtistname()"></div>
  </a></div> 
 	</div>


       
  	<div class="clear"></div> 
    
    
    
  	
  <div class="grid_4" id="artist_container1">
    <a href="images/01_md.jpg"><img src="images/01_sm.jpg" width="100" height="100" class="small" alt="Small image Blue Sails" /></a>    
  		<p class="text" id="bluesails">Blue Sails</p>
  </div>
  
  
  <div class="grid_4" id="artist_container2">

  </div>
  
  
  <div class="grid_4" id="artist_container3">

    	<p class="text" id="bigsky">Big Sky</p>
  </div>
  
  
  <div class="clear"></div>
  
  
  <div class="grid_4" id="artist_container4">
  <a href="images/04_md.jpg"><img src="images/04_sm.jpg" width="100" height="100" class="small" alt="Small Image Night Lights" /></a>
    	<p class="text" id="nightlights">Night Lights</p>
  </div>
    
    
  <div class="grid_4" id="artist_container5">
  <a href="images/05_md.jpg"><img src="images/05_sm.jpg" width="100" height="100" class="small"  alt="Small Product Image Firey Sunset"/></a>
    	<p class="text" id="fireysunset">Firey Sunset</p>
  </div>
  	
    
  <div class="grid_4" id="artist_container6">
  <a href="images/06_md.jpg"><img src="images/06_sm.jpg" width="100" height="100" class="small"  alt="Small Product Image Brilliant Sunrise"/></a>
    	<p class="text" id="brilliantsunrise">Brilliant Sunrise</p>
