Add HTML5 sandbox attribute to an iframe using Javascript

I've got an empty iframe and a button:

<input type="button" name="B1" value="google" onclick="frames['IFrameName1'].location.href='https://www.google.com/'">

But (besides .location.href) i need to set the attribute sandbox="allow-forms allow-scripts allow-same-origin, because the framed site "deframes". How to set location AND sandbox?

Solution

  • If you want to do two things on one click event. Have a function do both of those things and fire that function on click.

    window.onload = function(){
    var button = document.getElementsByName("B1")[0]
    var iframe = document.getElementsByName("IFrameName1")[0]
    button.addEventListener('click',addSandboxAndChangeLocation,false);

    function addSandboxAndChangeLocation(){
       frames['IFrameName1'].location.href='https://www.google.com/';
       iframe.sandbox = 'allow-forms allow-scripts allow-same-origin';
    }
}
