How to update a div's content in IE8 using JavaScript?

I am trying to modify the content of a div with JavaScript/jQuery. The implementation works well on newer browsers like IE9, Firefox, Chrome, Safari, and Opera, but it does not function correctly in Internet Explorer 8. I have experimented with methods such as .append, .appendTo, and .innerHTML, yet the div remains empty.

Could you help identify the issue? Here is a portion of my script:

<script type="text/javascript">
$(document).ready(function() {
    var divs = $('.content_area');

    if (divs.length === 0) {
        return;
    }
    var targetDiv = divs.first();

    targetDiv.block();
    $.get("your_url_here", function(response) {
        if ($.browser.msie) {
            alert(targetDiv.html()); // should show content
            targetDiv.empty();
            targetDiv[0].innerHTML = String(response);
            alert(response); // displays the expected HTML
            alert(targetDiv.html()); // remains empty
        } else {
            targetDiv.html(response);
        }
        targetDiv.unblock();
    });
});
</script>

IE8 has limitations with methods like innerHTML when dealing with AJAX responses. Try to use innerHTML directly without String() conversion. Ensure your AJAX response is well-formed. Here's a revised snippet:

<script type="text/javascript">
$(document).ready(function() {
    var divs = $('.content_area');

    if (divs.length === 0) {
        return;
    }
    var targetDiv = divs.first();

    targetDiv.block();
    $.get("your_url_here", function(response) {
        if ($.browser.msie) {
            targetDiv[0].innerHTML = response; // Avoid String()
        } else {
            targetDiv.html(response);
        }
        targetDiv.unblock();
    });
});
</script>

Test it to see if it resolves your issue in IE8.

Updating content in IE8 can be tricky due to its limited JavaScript support. Here's a solution focusing on IE8's quirks and ensuring your content updates correctly:

<script type="text/javascript">
$(document).ready(function() {
    var divs = $('.content_area');

    if (divs.length === 0) {
        return;
    }
    var targetDiv = divs.first();

    // Block the targetDiv before loading content
    targetDiv.block();

    $.get("your_url_here", function(response) {
        // Check for IE8
        if (navigator.userAgent.indexOf('MSIE 8.0') > -1) {
            targetDiv[0].innerHTML = response; // Direct assignment to innerHTML
        } else {
            targetDiv.html(response);
        }
        targetDiv.unblock();
    });
});
</script>

Actionable Steps:

  • Directly use targetDiv[0].innerHTML = response for IE8 compatibility.
  • Remove String() conversion, as it's unnecessary and could interfere with rendering.
  • Ensure your AJAX response contains well-formed HTML.

Give this a try and see if it resolves the issue. Let me know how it goes!
