要遍历页面的所有iframe元素,请使用jQueryeach()
方法。您可以尝试运行以下代码,以了解如何遍历所有iframe。我们在下面创建了三个iframe-
<!DOCTYPE html>
<html>
<head>
<script src="https://cdn.staticfile.org/jquery/3.2.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("button").click(function(){
$("iframe").each(function(){
alert($(this).text())
});
});
});
</script>
</head>
<body>
<iframe src="https://www.qries.com">Qries Q/A</iframe>
<iframe src="https://(cainiaojc.com)">Nhooo Free Learning</iframe>
<iframe src="https://sendfiles.net">Send Files</iframe><br>
<button>Loop through iFrames</button>
</body>
