Asynchronous processing the creation of Invoices without freezing Efficy

Thu, 16 Mar 2017 14:57:06 +0000

Hi,

i'm working on a process to handle all or a selection of invoices from the Cash Machine. My intention is to make this process asynchronous without freezing Efficy for the user which starts the process.

I've managed to create an asynchronous process that sends the invoices but I haven't been able to make the asynchronous process not freezing Efficy.

What i've got so far is the following:

        var processList = [];
    function getProcessed(elements) {
        // this function must be inside the outer function
        // so that `i` (below) can be accessed via a closure
        function processElement() {
            // do work on elements[i] here
            // or pass it to another function
            //setTimeout("", 10000);
            html = processProject(elements[i]);

            // this continues only if we haven't hit the end of the array,
            // like the second and third clauses of a `for` loop
            if (++i < elements.length) {
                setTimeout(processElement, 0);
            }
        }

        // don't bother with empty arrays
        if (elements.length) {
            processAjaxReturn = true;
            $("#waitSend").removeClass("hide");
            $("#soapStatus").show();

            // the same `i` is used each time processElement runs
            // and acts just like a `for` loop index
            var i = 0;
            var html;

            // optional: make a copy of the array so that it
            // doesn't get modified while we're working
            elements = elements.slice();

            // even a zero-millisecond "delay" gives the browser the
            // opportunity to run other code
            setTimeout(processElement, 0);
        }
    }

    function processAllProjects() {
        requirejs(["misc/utils"], function (Utils) {
            if (document.getElementsByName("Master").length > 0 && document.getElementsByName("Master")[0].checked) document.getElementsByName("Master")[0].checked = false;
            var extraParams = "queryKey=<%GetArgument('key')%>";
            Utils.runScriptAjax2("Invoice", "getAllProjects", extraParams, function (args, html) {
                var processList = html.split(",");
                countlength = processList.length;
                getProcessed(processList);
            });
        });
    }

    function processSelProjects() {
        if (processList.length === 0) 
            alert("<%GetLabel('The selection is empty')%>");
        else {
            if (document.getElementsByName("Master").length > 0 && document.getElementsByName("Master")[0].checked) document.getElementsByName("Master")[0].checked = false;
            countlength = processList.length;
            getProcessed(processList);
        }
    }

    var processAjaxReturn = false,
        counter = 0,
        countlength;
    function processProject(projKey) {
        try {
            requirejs(["misc/utils"], function (Utils) {
                var extraParams = "K_PROJECT="+projKey;
                extraParams += "&CashMachCall=1";
                html = Utils.runScriptAjax2("Invoice", "createCashMachineInvoice", extraParams, function (args, html) {
                    if (html.indexOf("##_##") && html.split("##_##")[0] > 0) uncheckCheckbox(projKey);
                    $("#soapStatus").html("<%GetLabel('Processed')%>: "  + (counter+1) + " / " + countlength);
                    counter++;
                    if (counter === countlength) {
                        $("#soapStatus").hide();
                        ajaxCompleted(html);
                        RefreshWindow();
                    }
                    return html;
                });
            });
        } catch (ex) {
            console.log('<%GetLabel("Efficy Error", type="jstext")%>: function processProjects(). <%GetLabel("Message:", type="jstext")%>\n' + ex.message);
        }
    }

    function ajaxCompleted(soapResult) {
        if (! processAjaxReturn) return;
        var resultArray;
        $('#waitSend').addClass('hide');
        soapResult = soapResult || $('#soapStatus').html();
        try {
            resultArray = soapResult.split('##_##');
            if (+resultArray[0] === 0)
                alert('<%GetLabel("Error while processing the projects", type="jstext")%>: ' + resultArray[1]);
            else
                alert('<%GetLabel("Projects processed!", type="jstext")%>');
        }
        catch(ex) {
            throw new Error('<%GetLabel("Error while reading the response", type="jstext")%>: ' + ex.message + '; request: ' + soapResult);
        }
        processAjaxReturn = false;
    }

Has someone an idea on how I could make this process so that Efficy isn't freezing anymore?

Best regards,
Jeroen
