父页面调用子页面方法

参数:fun()为子页面的函数
注意:$("#iframeID")[0]后面这个[0]必须要,亲测,删除就报错了,其原因是contentWindow是原生js的方法,所以用.eq(0)都不行。

layer弹出iframe层

layer弹出iframe层,其他都差不多,主要是如何找到iframe,先看下一般的layer调用iframe弹框代码:

layer.open({
  type: 2,
  title: '我是子iframe页面',
  shadeClose: true,
  shade: 0.8,
  area: ['380px', '90%'],
  content: './son.html'    //iframe的url
}); 

于是我就想给这个iframe弹框设置一个id,

layer.open({
  id:"son",
  type: 2,
  title: '我是子iframe页面',
  shadeClose: true,
  shade: 0.8,
  area: ['380px', '90%'],
  content: './son.html'    //iframe的url
}); 

再通过这个id进行操作,操作方法和上面介绍的方法对应就可以,可是这种方法太繁琐,我又找了个更好的办法——利用layer的success回调函数

layer.open({
  type: 2,
  title: '我是子iframe页面',
  shadeClose: true,
  shade: 0.8,
  area: ['380px', '90%'],
  content: './son.html',    //iframe的url
  success:function(dom){
    let $iframeDom=$(dom[0]).find("iframe").eq(0).contents();
    $iframeDom.find("#test").html("我是从父级传来的值哟……")
  }
}); 
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>父级页面</title>
    <script src="https://code.jquery.com/jquery-2.2.4.min.js"></script>
    <script src="layer.js"></script>
    <style>
        .btn{display:inline-block;height:30px;line-height:30px;border-radius:5px;background:darkturquoise;padding:5px 12px;color:#fff;cursor:pointer;margin-right:20px;}
    </style>
</head>
<body>
<div>
    <span id="father_dataChange" class="btn">layer弹出iframe层</span>
</div>
<iframe id="iframe_dataChange" src="son.html" frameborder="0"></iframe>
<script>
  $("#father_dataChange").click(function () {
    layer.open({
      id:"son",
      type: 2,
      title: '我是子iframe页面',
      shadeClose: true,
      shade: 0.8,
      area: ['380px', '90%'],
      content: './son.html',
      success:function(dom){
        let $iframeDom=$(dom[0]).find("iframe").eq(0).contents();
        $iframeDom.find("#test").html("我是从父级传来的值哟……")
      }
    });
  })
</script>
</body>
</html>

son.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>子级页面</title>
    <script src="https://code.jquery.com/jquery-2.2.4.min.js"></script>

<body>
<div id="test"></div>
