The small collection of project experience (1) ___js gets the value from the previous page URL

Page Jump code: src= "addclffour.aspx?id=<%= request.querystring[" ID "]. ToString ()%> ">, via" request.querystring["ID". ToString () "Pass the parameter ID to addclffour, how do I get the ID value of the page from the Addclffour page?"

Here are three ways to simply describe how to implement JS to get the values from the previous page

1. The simplest method   

var wxjdid= <%=request.querystring["ID"]%>;

Get the ID by request.querystring.

2. With Addclffour backstage

public string Strwxjd; The background defines      the variable strwxjd=request.querystring["ID". ToString (); Receive the ID value passed over

JS to receive the ID on it.

var wxjdid= "<%= strwxjd%>";

Using a function in 3.js

function Getparameterbyname (name) {           name = Name.replace (/[\[]/, "\\\["). Replace (/[\]]/, "\\\]");           var regexs = "[\\?&]" + name + "= ([^&#]*)";            var regex = new RegExp (REGEXS);           var results = regex.exec (window.location.search);             if (results = = NULL)                    return null;            else                    return decodeURIComponent (Results[1].replace (/\+/g, ""));          }

JS in the Call Method Getparameterbyname () can.

For this issue, only the implementation of these three methods is verified for the time being. The problem is that the project needs to be produced, although very simple, I think it is necessary to tidy up a bit.
