Hi, I'm having some ridiculous issues with javascript right now.
I've got some arrows that order some tabular data in a web page. The HTML element that controls this is:
The function declared in the onclick attribute with the parameter of 1 is this:
Ignore showList("") because the function ammendSortFlags(str) looks like this:
My issue is that the lines:
and
don't actually work. They maintain the original src in the image which was price_off.gif
Does anybody actually see what could be the cause of the problem here, because I've tried moving it around and moving it back. The swapImage and imageRestore functions do work (They're standard Macromedia functions), but I wonder if the imageRestore is somehow caching and remember the original image src and not acknowledging any changes I make to the actual image?
When selecting my elements in my page and viewing selection source in Firefox, the original image of price_off.gif is still present as though no modification has been made.
Any help's appreciated, as I'm at the end of my tether!
The code for the swapping functions is shown below, although it's quite hard to read, and has been proven across many other sites in the past.
Cheers,
Karl.
I've got some arrows that order some tabular data in a web page. The HTML element that controls this is:
Code:
<a href="#" onMouseOver="MM_swapImage('indicator1','','images/result_headers/price_ondown.gif',1)" onclick="changeSort(1);" onmouseout="MM_swapImgRestore()" id="link1" name="link1" title="price">
<img src="images/result_headers/price_off.gif" id="indicator1" name="indicator1" alt="Price" />
</a>The function declared in the onclick attribute with the parameter of 1 is this:
Code:
function changeSort(str)
{
ammendSortFlags(str)
showList("")
}Ignore showList("") because the function ammendSortFlags(str) looks like this:
Code:
function ammendSortFlags(val)
{
var prevSort = parseInt(document.getElementById("sortCol").value);
var imageType = '';
var prevImageType = '';
var imageName = 'indicator' + val;
var linkName = 'link' + val;
var prevLinkName = '';
switch(val) {
case 1:
imageType = 'price';
break;
case 2:
imageType = 'location';
break;
case 3:
imageType = 'make';
break;
case 4:
imageType = 'bedrooms';
break;
}
if (document.getElementById("sortCol").value == val)
{
if (document.getElementById("sortDir").value == "ASC")
{
document.getElementById(imageName).src = 'images/result_headers/' + imageType + '_ondown.gif';
document.getElementById("sortDir").value = 'DESC';
document.getElementById(linkName).setAttribute('onMouseOver','MM_swapImage(\'indicator'+val+'\',\'\',\'images/result_headers/' + imageType + '_onup.gif\',1)');
}

}My issue is that the lines:
Code:
document.getElementById(imageName).src = 'images/result_headers/' + imageType + '_ondown.gif';and
Code:
document.getElementById(imageName).src = 'images/result_headers/' + imageType + '_onup.gif';don't actually work. They maintain the original src in the image which was price_off.gif

The code for the swapping functions is shown below, although it's quite hard to read, and has been proven across many other sites in the past.
Code:
function MM_swapImage() { //v3.0
var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3)
if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];}
}
function MM_preloadImages() { //v3.0
getLinksToBlur()
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}
function MM_swapImgRestore() { //v3.0
var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;
}
function MM_findObj(n, d) { //v3.0
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document); return x;
}Cheers,
Karl.
