Get query string values in JavaScript

In Java script i have a variable that holds the value &name=John&age=12&roll=2 for ex:

var data =  "&name=John&age=12&roll=2"

How can I separately fetch these three values? ie value of name, age and roll

Answer 1

var data = "&name=John&age=12&roll=2".split("&") gives you an array of pairs.

thisData= data[0].split("=") gives you thisData[0] = "name" and thisData[1] = "John"

You can write a loop to extract all of the data.

Answer 2

You can use data.split first split it by "&" and then "="

Answer 3

var dataparts = data.split("&");
for(var i =0;i<dataparts.length;i++){
     var part = dataparts[i]; 
//do something with the dataparts here
}

Answer 4

Split by & leaving out the first & and then by = and get the value at 1

var data =  "&name=John&age=12&roll=2";
var datas =data.substr(1,data.length).split('&');
for(var i =0; i<datas.length;i++){
    alert(datas[i].split('=')[1]);
}
