javascript - Not getting response in ajax success function -

javascript code:

window.gettablecontent = function() {   $.ajax({     url: "/oeb_infos/" + $("#oeb_info_id").val() + "/show_toc.js",     type: "get",     async: false,     success: function(data) {       alert(typeof data);       if (data) {         data = $.parsejson(data);         $("#toc.toc").html("<ul>");         $.each(data, function(header) {           var value;           value = '';           $.each(header.list, function(j) {             return value = value + "<ul>";           });           value = value + ("<li><a href='#" + toc_part['id'] + "'>" + toc_part['value'] + "</a></li>");           $.each(header['list'], function(j) {             return value = value + "</ul>";           });           $("#toc.toc").append(value);         });         $("#toc.toc").append("</ul>");       }     }   }); };
