Request Class of Javascript-html

Javascript|request

To do the conversion of the Chinese and English, to get the exact parameters and take out, so do a simple HTML in the use of JS to get the address bar of an object.
There are three ways:
1, request. QueryString ("Parameters")//Gets the specified parameter, returns a string;
2, request. Querystrings ()//Get all the parameters and return the array;
3, Request.setquery ("parameter", "value of the parameter");//If this argument is present in the current address bar, this parameter is updated, otherwise a new Address bar argument string is returned.
For example:
The current address bar parameter string is:? name=a&site=never_online

Alert (request.setquery ("name", "Bluedestiny"))

If "name" is in the Address bar argument, then return? name=bluedestiny&site=never_online

The Setquery method has the function of automatically appending parameters. Such as:
The current address bar parameter string is:? site=never_online
Alert (request.setquery ("name", "Bluedestiny"))
Then return? site=never_online&name=bluedestiny

Similarly, if the address bar has no parameters, the parameters are automatically appended
Alert (request.setquery ("name", "Bluedestiny"))
Back? name=bluedestiny
