When you google on this topic you will find many ways to get Query String parameters & its values using JavaScript. Below is one of the smallest, easiest and a clean code for the same purpose. I found this code from Ben Nadel’s Blog post mentioned below.
1: function GetQueryStringValue(parameterName) {
2: var objQRs = new Object();
3:
4: window.location.search.replace(new RegExp("([^?=&]+)(=([^&]*))?", "g"),
5: function($0, $1, $2, $3) { objQRs[$1] = $3; });
6:
7: return objQRs[parameterName]
8: }
So if you have a url like page.html?id=1000&code=zoox&dt=10/31/2009 you can use following code to retrieve the values of querystring parameters id, code and dt.
1: var id= GetQueryStringValue("id");
2: var code = GetQueryStringValue("code");
3: var dateValue = GetQueryStringValue("dt");
If the parameter key passed to GetQueryStringValue() does not exists in query string then it returns ‘undefined’.
