Flatten a javascript object to pass as querystring

Question

I have a javascript object that I need to flatten into a string so that I can pass as querystring, how would I do that? i.e:

{ cost: 12345, insertBy: 'testUser' } would become cost=12345&insertBy=testUser

I can't use jQuery AJAX call for this call, I know we can use that and pass the object in as data but not in this case. Using jQuery to flatten to object would be okay though.

Thank you.

Answer 1

You want jQuery.param:

var str = $.param({ cost: 12345, insertBy: 'testUser' }); // "cost=12345&insertBy=testUser" 

Note that this is the function used internally by jQuery to serialize objects passed as the data argument.

Here's a non-jQuery version:

function toQueryString(obj) {     var parts = [];     for (var i in obj) {         if (obj.hasOwnProperty(i)) {             parts.push(encodeURIComponent(i) + "=" + encodeURIComponent(obj[i]));         }     }     return parts.join("&"); }
