在涉及银行页面时，需要跳转到银行页面

var accound = document.getElemntById(‘accound‘);
$.ajax({
   dataType:‘json‘,
   type:‘post‘,
   url:‘/user/updataCard.do‘,
   data:accound,
   timeout:300,
   success:function(data){

      document.getElementById(‘ld-frame‘).contentWindow.location.href = http://www.mamicode.com/data;
   }

})

页面显示

<div><input type=‘text‘ id=‘accound‘/></div>
<div class="ldwrap">
      <iframe id="ld-frame" frameborder="0" width="100%" height="100%" src="http://www.mamicode.com/loading.html" scrolling="no"></iframe>
