I am currently working on a project that involves using JavaScript to extract information from a view (implemented in Python and utilizing the Django interface) based on the text input by a user into a field (triggering a query on every keystroke), and then displaying that information back. In essence, it either shows 'no job found' or provides details such as name, username, and balance for the corresponding job. Everything functions smoothly in Firefox - I can input a JobID, it confirms its new status, and I can proceed to create the job. Upon returning to the page and entering the same ID again, I receive the correct job information.

The predicament lies with Internet Explorer 8 acting sluggishly. When I enter a job ID in IE8, my function calls the lookup page (/deposits/orglookup/?q=123) and retrieves a value. For instance, if the value is False, I can then create a new job using that ID. However, upon revisiting the field and entering the same number, Internet Explorer fails to refresh the lookup page, leading to another false result. By navigating to the lookup page, I can see the false value but refreshing yields the accurate information once more. Any suggestions on how I can ensure that this query executes each time I type in the lookup field, instead of IE referencing the cached page?

It should be noted that resolving this issue individually for users would not prove beneficial since this is an organization-wide application, hence requiring a universal fix that can be incorporated somewhere in the code to prompt IE to consistently refresh the lookup page when needed.

Below is the code snippet for the lookup function which might provide insight, despite its complexity:

$("#id_JobID").keyup( 

    function(event){

        //only fire gets on 0-9, kp 0-9, backspace, and delete
        if (event.keyCode in { 96:1, 97:1, 98:1, 99:1, 100:1, 101:1, 102:1, 103:1, 104:1, 105:1,
                                46:1,48:1, 49:1, 50:1, 51:1, 52:1, 53:1, 54:1, 55:1, 56:1, 57:1, 8:1}) 
        {

            if ($("#loadimg").attr("src") != "/static/icons/loading.gif") {
                $("#loadimg").attr("src", "/static/icons/loading.gif");
            }

            if ($("#loadimg").length < 1) {
                $("#id_JobID").parent().append("<img id=loadimg src=/static/icons/loading.gif>");
            }

            clearTimeouts(null); //clear all existing timeouts to stop any running lookups
            GetCounter++; 
            currLoc = window.location.href.slice(window.location.href.indexOf('?') + 1).split('/').slice(-2,-1);

            if (currLoc == 'restorebatch') {
                var TimeoutId = setTimeout(function() {dynamicSearch('restorelookup');}, 400);
            } else {
                var TimeoutId = setTimeout(function() {dynamicSearch('orglookup');}, 400);
            }

            //alert(TimeoutID);
            TimeoutBag[GetCounter] = {
                'RequestNumber': GetCounter,
                'TimeoutId': TimeoutId
            }
        }
    }
);

function clearTimeouts(TimeoutBagKeys) //TimeoutBagKeys is an array that contains keys into the TimeoutBag of Timeout's you want to clear
{
    if(TimeoutBagKeys == null) //if TimeoutBagKeys is null, clear all timeouts.
    {
        for (var i = 0; i < TimeoutBag.length; i++)
        {
           if (TimeoutBag[i] != null) {
            clearTimeout(TimeoutBag[i].TimeoutId);
           }
        }
    }
    else //otherwise, an array of keys for the timeout bag has been passed in. clear those timeouts.
    {
        var ClearedIdsString = "";
        for (var i = 0; i < TimeoutBagKeys.length; i++)
        {
            if (TimeoutBag[TimeoutBagKeys[i]] != null)
            {
                clearTimeout(TimeoutBag[TimeoutBagKeys[i]].TimeoutId);
                ClearedIdsString += TimeoutBag[TimeoutBagKeys[i]].TimeoutId;
