I have been searching for days now.

I have some random numbers that are generated automatically with crunch function on 3 minute interval:

setInterval(crunch, 180000);

then I can nicely highlight the return random numbers with mark.js:

$(function() {
        var mark = function() {
            // Read the keyword
            var keyword = $("input[name='keyword']").val();
            var keyword2 = $("input[name='keyword2']").val();
            // Remove previous marked elements and mark
            // the new keyword inside the context
            $(".context").unmark({
                done: function() {
                    $(".context").mark(keyword).mark(keyword2, {
                        className: 'secondary'
                    });
                }
            });
        };
        $("input[name^='keyword']").on("input", mark);
    });

My problem is when the second lot of new numbers are generated the highlight goes away - please can you kindly share a way how I can make them stay highlighted forever?

Here is my working fiddle on a 3 min interval:

min: 1 max: 100 results: 100

I tend to search for the highlighted number after generation not sure how to make it search on generation apologies.

Many thanks in advance!
