I am using javascript to highlight text in markup. I can successfully change the markup, as seen in the browser developer tool (chrome), but rendered code as appears in browser window does not change. Does anyone see what i am doing wrong?

<script type="text/javascript">
    $(document).ready(function (e) {
        $('#submit').click(function (e) {
            try {
                var $inputTxt = $('#search');
                result = $inputTxt.val();
                alert(result);
 

        $('p').each(function () {
 
            var a=$(this).html().toString();
            var aindx=[];
 
            while(a.indexOf(result) >

I see that you're using a tag, <mark/> - one I've not seen before. Some browsers used to disallow styling of non-standard elements, I've no idea on the current state of affairs.
If the HTML is changing, but the display isn't - I'd look at the CSS to check the style of 'mark' elements.

Even quicker, just add something like the following to your css:

mark
{
background-color: yellow;
}

Good point. I think, with any thinkable state of affairs, using not HTML predefined tag makes no sense at all.

Solution 1

<mark>
is a standard HTLML5 tag used to highlight text.

The intention here was to insert the mark tag into the text to display the searched for text as highlighted.
