没有调用iframe src;虽然网址准备好了

Question

我有一个iframe，jQuery ready函数创建了Url。但是iframe没有加载src。请帮忙。

<sbFrame.js file>

sb.util.transformUrl = function(){
try
{
  var category = document.getElementById('id').value,
      zip = document.getElementById('zip').value,
      src = jQuery('#resize').attr('src');

  var source = src + '?catOid=' + category
                                + '&zip='
                                + zip;

  console.log(source); //URL transformed.
  jQuery('#resize').attr('src', source);
}
 catch (e) {
  alert('exception: ' + e);
 }
 };

jQuery(document).ready(function(){
 sb.util.transformUrl();
});

<div id="container">
<iframe id="resize" scrolling="NO" style="padding:0; width:626px;" frameborder="0"
  src="/details/results" onload="Iframe_Load(this)" />

</div>
