父页面获取子页面元素
- 格式:
$("#iframeID").contents().find("#eleID") - 示例代码:
father.html
<!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>
<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">父向子传值</span>
</div>
<iframe id="iframe_dataChange" src="son.html" frameborder="0"></iframe>
<script>
$("#father_dataChange").click(function () {
$("#iframe_dataChange").contents().find("#son_dataChange").html("我是父页面传过来的值……")
})
</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>
</head>
<body>
<div id="son_dataChange">我是子页面内容,点击“父向子传值”按钮我改变</div>
</body>
</html>
父页面调用子页面方法
- 格式:
$("#iframeID")[0].contentWindow.fun()
参数:fun()为子页面的函数
注意:$("#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。
- 示例代码:
father.html
<!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>
$("#father_fun").click(function () {
$("#iframe_fun")[0].contentWindow.son_fun()
})

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……")
}
});
- 示例代码:
father.html
<!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
