I inserted this iframe into a webpage
<iframe src='http://redbug.redrocksoftware.com.au:80/Pages/chamara.html' style="position:absolute;z-index:1;" ></iframe>
The chamara.html page has a button that, when clicked, should cover the current page with an overlay.
The button inside the iframe is for feedback:
Upon clicking it, I expect the following to happen:
Despite trying absolute positioning and z-index on the iframe, I have not been able to achieve the desired result yet.
Yay, just completed the demo! :P
Alright, let's get to it. If you want the iframe to cover the entire page only when a specific button is clicked, you can utilize jQuery to handle the click event. You will need to use contents() to access the iframe content and then use find() to target the desired element. Here's a basic example:
$("#iframe").contents().find("#iframe_button").click(function () {
// Button clicked!
})
To make the iframe cover the whole page, I've created this CSS class:
.iframe_cover {
position:absolute;
top:0;
left:0;
width:100% !important;
height:100% !important;
border:0;
}
So, when the button is clicked, the iframe will receive this class. See:
$("#iframe").contents().find("#iframe_button").click(function () {
$("#iframe").addClass("iframe_cover");
})
