javascript - jQuery param() function giving this.replace is not a function -

i have code:

function parsecontent(targetdiv) {     $("#"+targetdiv+" > [contentname]").each(function (index) {         var data = $(this).attr("contentdata");         if(data != undefined) {             alert(data);             alert(jquery.param(data));         }     }) } 

it parses html , looks elements contentname attribute in them. each of those, check see if there attribute contentdata, , if turn json parameters.

it's doing each() fine. 1 alert (the first one) prints:

{reportid : 5} 

which correct, fails , in console get:

typeerror: this.replace not function 

im pretty sure correct json format. have tried adding quotes {'reportid':5} same error;

any ideas?

it's because $.param expects json object parameter , not string formatted json. if pass this, it's going fail:

var jsonelement = '{"reportid": 5}'; var result = $.param(jsonelement); //throws exception 

instead, if do:

var jsonelement = '{"reportid": 5}'; var result = $.param(json.parse(jsonelement));
