The page in the iframe to set the attributes of the iframe (width, height)_html/css_WEB-ITnose

a.htm is the page to be nested. There is an iframe in b.htm that nests a.htm
I want to set the width of the iframe in b.htm through js in a.htm. , height

$(parent.window).width(1000);

Due to the same origin policy, the operation encountered an error: permission denied. (not the same domain name)
Is there any way to set b.htm in a.htm? This iframe (an iframe nested in a.htm)?

(Because we want to provide a widget, we give users this code: , but I want to have less code. I can't use js on the user's page (b.htm), all I can control is a.htm)

Cross-domain will not work

It involves cross-domain. . . Not easy to handle. .

This can completely meet your requirements.

Thank you everyone, I learned a lot of methods.

But I don’t have any control over b.htm (that is, I cannot add any js to b.htm or create files in this directory) , The method I found is to add js to b.htm to change the attributes of iframe
