<input type="text">
<form id="f1" action="/fakeajax/" method="post" target="ifr">
    <iframe name="ifr" id="ifr"></iframe>

    <input name="user" type="text">
    <a onclick="submit_form()">提交 </a>
</form>
</body>

       document.getElementById('f1').submit()
       document.getElementById('ifr').onload=loadiframe#绑定事件
    }
   function loadiframe() {

<body>

<form id="f1" action="/fakeajax" method="post" target="ifr">
    {% csrf_token %}
    <iframe name="ifr" id="iframe"></iframe>
    <input name="user" type="text">
    <a onclick="submit_form()">提交</a>
</form>

<script>
    function submit_form() {
       document.getElementById('f1').submit()
       document.getElementById('iframe').onload=loadiframe
    }
   function loadiframe() {
      var return_values=this.contentWindow.document.body.innerHTML
       var obj = JSON.parse(return_values)
      if(obj.status){

                alert(obj.status);
