How to pass an array as a URL parameter?

Question

I would like to pass an array and added to a link on my page as a URL parameter, because later on the server side I need the values from the array. How should I do that?

Answer 1

I'd go with this approach,

var myArray = ['aaa', 'bbb', 'ccc', ];

var myArrayQry = myArray.map(function(el, idx) {
    return 'myArray[' + idx + ']=' + el;
}).join('&');

// myArray[0]=aaa&myArray[1]=bbb&myArray[2]=ccc

Then, I retrieve the URL query params as an array on the server side.
