Question

I have a div tag and i’m changing its innerHtml attribute. And i want to add listener to this div tag to show/hide when its innerHtml changed.

Answer 1

You can use setInterval to check the contents periodically, and act accordingly, for example:

function innerHTMLChanged() {
    if$("#myDiv").html() != "Some HTML for comparison, perhaps the previous state?") {
        $("#myDiv").hide();
    } else {
        $("#myDiv").show();
    }
}

// fires every half a second
setInterval(innerHTMLChanged, 500);
