如何从jQuery ajax调用javascript函数？

Question

I have jQuery ajax call to get results from the server, and in success, the code should call javascript function which is not in jQuery region code, so I got error in firebug: that the call of function doesnt have reference.

here is my code (see the ajax call in function addGMarker):

function test1234(res) {
    PreInfo = res;

    popupContentHTML = deviceMoreinfo_callBack_ForGoogle(PreInfo);

    var sum = '<p>Please, Select <b>[Sensors Reading List]</b> tab to view vehcile sensors reading, and select <b>[Device Communication Commands]</b> tab to send commands for the device:</p><br/>';
    var tabs = [
new MaxContentTab('Sensors Reading List', maxContentDiv),
new MaxContentTab('Device Communication Commands', maxContentDivForCommands)];

    this.openMaxContentTabsHtml(map, popupContentHTML, sum, tabs, { maxTitle: "Sensors and Features" });

    var iw = map.getTabbedMaxContent();
    iw.id = this.id;

    GEvent.addListener(iw, 'selecttab', function (tab) {
        var node = tab.getContentNode();

        switch (tab.getLabel()) {
            case 'Sensors Reading List':
                maxContentDiv.innerHTML = '<IMG SRC="../../../images/FullModeIcons/LoadingImage.gif" /> Loading...';
                //GetSensorsReading(this.id, ClientID, "En", GetSensorsReading_CallBack);
                jQuery.ajax({
                    type: "POST",
                    url: "../../../DevicesManagerAjax.asmx/GetSensorsReading",
                    data: "{Device_ID: '" + this.id + "', ClientID: '" + ClientID + "', Page_ID: 'En'}",

                    timeout: 70000,
                    success: function (msg) {
                        var res = msg.d;
                        GetSensorsReading_CallBack(res);
                    },
                    error: function (xhr, status, errorThrown) {
                        alert("An error occered, " + errorThrown);
                    }
                });
                break;

                maxContentDivForCommands.innerHTML = '<IMG SRC="../../../images/FullModeIcons/LoadingImage.gif" /> Loading...';
                //GetContorolableSensors(this.id, ClientID, "En", GetContorolableSensors_CallBack);
                jQuery.ajax({

Answer 1

It's the same code for calling Javascript function from jQuery. It's working fine. The problem is elsewhere in your code.

This might not be the exact solution, but given not to divert from the solution.

function test1234(res) {
    alert(res)
}

function Test() {
    jQuery.ajax({
        type: "POST",
        url: "/TestWebApp/ProcessServlet.do",
        success: function (res) {
            alert(res);
            test1234(res);
        },
        error: function (xhr, status, errorThrown) {
            alert("An error occered, " + errorThrown);
        }
    });
}
