The example in this article describes the method of realizing iframe frame value in js. Share it with everyone for your reference, the details are as follows:

Why are there so many different browsers in the world? Every time I encounter browser compatibility issues with js/css, I always sigh like this. I really hope that all these browser companies will fall and only one will remain (obviously this is an impossible wish) , let’s get back to the point, let’s look at the code:

Page inside iframe: 

<html>
<head>
  <title>框架内页</title>
</head>
<body>
  <div>
    <input id="txt1" name="txt1" type="text" value="测试" />
  </div>
</body>
</html>

Parent class: 

<iframe name="frame1" id="frame1" src="frm.html" frameborder="1" height="30"></iframe>
<p>
  iframe1中文本框的值:</p>
<p>
  <input type="button" name="Submit" value="getValue" onclick="getValue()" />
</p>
<script type="text/javascript">
function getValue(){
  var ofrm1 = document.getElementById("frame1").document;
  if (ofrm1==undefined)
  {
    ofrm1 = document.getElementById("frame1").contentWindow.document;
    var ff = ofrm1.getElementById("txt1").value;
    alert("firefox/chrome取值结果为:" + ff);
  }
  else
  {
    var ie = document.frames["frame1"].document.getElementById("txt1").value;
    alert("ie取值结果为:" + ie);
  }
}
</script>

I hope this article will be helpful to everyone in JavaScript programming.
