javascript - Use jQuery .append() inside a function? -

i've been trying call function appends html tags inside of pre-existing div tags this:

function loadtextbox(jsonurl,divid){ $.getjson(jsonurl, function(json) {     alert('hello');     $('#' + divid).append('<h2></h2>')         .find('h').append(json.heading).attr(json.config.backgroundconfig)         .find('h').attr(json.config.headingconfig).append(json.heading).parent()         .find('p').attr(json.config.bodyconfig).append(json.body);     }) } 

this complex example haven't been able working append() function inside sort of other function. can append fine straight .js otherwise no luck. know fact json calls working use identical call , queries different function. there problem putting append() in function?

edit: note, above alert not work is. if moved 1 line (above $.getjson call works fine. maybe important? also, calling function directly below in same .js file so:

loadtextbox("./json/textbox.json","text"); 

if alert never shows up, when inside function, means you're not receiving response.

if you're using firefox, use firebug plugin see if exception thrown serverside.
