i tried that, there was no value; i just alerted it upon onlicking the function getVal() { event. alert(window.location.search) } www.google.com/myfile.php?id=123 onclick="getVal"
After reading the comments, it looks like you want a way to get the query string off a url, but not the current url.
function getParameters(url){
var query = url.substr(url.lastIndexOf('?'));
// If there was no parameters return an empty object
if(query.length <= 1)
return {};
// Strip the ?
query = query.substr(1);
// Split into indivitual parameters
var parts = query.split('&');
var parameters = {};
for(var i = 0; i < parts.length; i++) {
// Split key and value
var keyValue = parts[i].split('=');
parameters[keyValue[0]] = keyValue[1] || '';
}
return parameters;
}
function alertId(a){
var parameters = getParameters(a.href);
alert(parameters.id);
}
//onclick="alertId(this); return false;"

i got undefined upon onclick hmmm
NULL
made the change but still says undefined..hmmm
NULL
i think maybe of the way its been called. the pages get loaded already on the screen. the url is not displayed on the location bar either.but when you mouse over the thumbnail images, you see the url, and i want that id. any ideas?
NULL
<a href="test.ca/images/image-1.jpg?id=1" onclick="swap(this); clicked(); return false;">thumbnailimages src</a>
NULL
ah i know what the problem is. so your code works. but its not sort of doing what i want. i guess i needed to be more specific. i have thumbnail imaages. when you click on the thumbnail images, it swap the image with a small window, just like a picture veiwer: highslide.com now i am passing a variable with the image, and i want that variable. i dont want the location url variable. is this clearer?
