Posted by Erik on Jan 15 2006 @ 19:12 :: 9111 unique visits
Just one simple function:CODE: JAVASCRIPT
function getget(name) {
var q = document.location.search;
var i = q.indexOf(name + '=');
if (i == -1) {
return false;
}
var r = q.substr(i + name.length + 1, q.length - i - name.length - 1);
i = r.indexOf('&');
if (i != -1) {
r = r.substr(0, i);
}
return r.replace(/\+/g, ' ');
}
var q = document.location.search;
var i = q.indexOf(name + '=');
if (i == -1) {
return false;
}
var r = q.substr(i + name.length + 1, q.length - i - name.length - 1);
i = r.indexOf('&');
if (i != -1) {
r = r.substr(0, i);
}
return r.replace(/\+/g, ' ');
}
Example usage: in index.html
CODE: JAVASCRIPT
alert('Hello: '+getget('name'));
If you open this index.html with index.html?name=Erik it will alert "Hello: Erik".

Hi, I am a new comer in web development and web programming field. At present, I am working on parameters in java script after my certification exams VCP-310 for VMware Certified Professional on VI3.5 and 640-802 Exam. These there is a gap between my exams so that’s why I am working on java script. My next exams are going to start on next month including 350-001 Exam for becoming CCIE Cisco Certified Internetworking Expert and 70-290 Exam for Managing and Maintaining a Microsoft Windows Server 2003 Environment. After these two exams there will only one exam remaining that exam is Microsoft 70-640 Exam going to be held in the end. I must say that you did a nice job by writing the handy code. Keep carry on the handy work man.7. On May 01 2009 @ 10:16 LukeDeverock wrote:

If the request string has DoNotUpdate=true this method would match this pattern when called with Update, the script correctly finds the equals sign at the end of the parameter, but does not check that the request parameter starts with a ? or &.9. On May 13 2009 @ 15:50 guest wrote:
