Get querystring array values in Javascript

rated 0 times [ 200] [ 4] / answers: 1 / hits: 19365 / 11 Years ago, sun, april 7, 2013, 12:00:00

I have a form that uses the get method and contains an array:

http://www.example.com?name[]=hello&name[]=world

I'm trying to retrieve array values 'hello' and 'world' using JavaScript or jQuery.

I've had a look at similar solutions on Stack Overflow (e.g. How can I get query string values in JavaScript?) but they seem to only deal with parameters rather than arrays.

Is it possible to get array values?

There you go: http://jsfiddle.net/mm6Bt/1/

function getURLParam(key,target){

    var values = [];

    if (!target) target = location.href;



    key = key.replace(/[[]/, \[).replace(/[]]/, \]);



    var pattern = key + '=([^&#]+)';

    var o_reg = new RegExp(pattern,'ig');

    while (true){

        var matches = o_reg.exec(target);

        if (matches && matches[1]){

            values.push(matches[1]);

        } else {

            break;

        }

    }



    if (!values.length){

        return null;   

    } else {

        return values.length == 1 ? values[0] : values;

    }

}



var str = 'http://www.example.com?name[]=hello&name[]=world&var1=stam';



console.log(getURLParam('name[]',str));

console.log(getURLParam('var1',str));
