javascript - Get Text from iframe

Question

asked Oct 24, 2021 in Technique[技术] by 深蓝 (71.8m points)

I have the following HTML

<iframe id ="myIframe">
     #document
         <head>...</head>
        <body>Text I want to get is here</body>
</iframe>

I only know the iframe's id. Using JavaScript, how can I extract the text from the body?

Assuming your iframe is in the same domain as your HTML:

var myIFrame = document.getElementById("myIframe");
var content = myIFrame.contentWindow.document.body.innerHTML;

Otherwise you'll face some Same Origin Policy issues.
