Question

I need to be able to call a function getProgress every second. This function does an ajax request and updates a progress bar. I need to be able to stop the call to this function when a call returned from ajax is "true".

Html:

<td class="checkbox">
<input type="checkbox" value="6" class="checkbox download" id="chk-6">
<div class="hide" id="prgbar-6"><span class="progresslabel"></span></div>
</td>

My function:

function getProgress(operationId) { // receives operationId
    $.post("@Url.Action("Status","Packages")", { operationId: operationId }, function (data) {
        if (data) {
            for (var key in data) {
                if ($("#prgbar-" + key + "").size() != 0) {
                    var objPrg = $("#prgbar-" + key + "");
                    var objchk = $("#chk-" + key + "");
                    if (data[key]) {
                        objPrg.find("span").text("downloading...").css("color:#000000");
                        objchk.hide();
                        objPrg.removeClass("hide").show().progressbar({
                            value: 0
                        });
                        var value = Math.floor(parseInt(data[key]) * 100);
                        objPrg.progressbar("option", "value", value);
                        objPrg.find("span").text(value + "%");
                    } else {

                    }
                }
            }
        }
    });
}

var interval = setInterval(function(){getProgress(operationId,interval)},1000);

In your $.POST complete callback function, clear this interval: {i use complete here but if you want to do only for successful request, use .success()}

$.post("@Url.Action("Status","Packages")", { operationId: operationId }, function (data) {
        if (data) {
            for (var key in data) {
                if ($("#prgbar-" + key + "").size() != 0) {
                    var objPrg = $("#prgbar-" + key + "");
                    var objchk = $("#chk-" + key + "");
                    if (data[key]) {
                        objPrg.find("span").text("downloading...").css("color:#000000");
                        objchk.hide();
                        objPrg.removeClass("hide").show().progressbar({
                            value: 0
                        });
                        var value = Math.floor(parseInt(data[key]) * 100);
                        objPrg.progressbar("option", "value", value);
                        objPrg.find("span").text(value + "%");
                    } else {

                    }
                }
            }
        }
    }).complete(function() { clearInterval(interval); });
