如何从jQuery ajax调用javascript函数？

Question

我有jQuery ajax调用来从服务器获取结果，并且成功地，代码应调用不在jQuery区域代码中的javascript函数，因此我在firebug中出错：该函数的调用没有引用。

这是我的代码（请参见函数addGMarker中的ajax调用）：

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'}",
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    timeout: 70000,
                    success: function (msg) {
                        var res = msg.d;
                        GetSensorsReading_CallBack(res);
                    },
                    error: function (xhr, status, errorThrown) {
                        alert("An error occered, " + errorThrown);
                    }
                });
                break;
            case 'Device Communication Commands':
                maxContentDivForCommands.innerHTML = '<IMG SRC="../../../images/FullModeIcons/LoadingImage.gif" /> Loading...';
                //GetContorolableSensors(this.id, ClientID, "En", GetContorolableSensors_CallBack);
                jQuery.ajax({
                    type: "POST",
                    url: "../../../DevicesManagerAjax.asmx/GetContorolableSensors",
                    data: "{Device_ID: '" + this.id + "', ClientID: '" + ClientID + "', Page_ID: 'En'}",

                        GetContorolableSensors_CallBack(res);
                    },
                    error: function (xhr, status, errorThrown) {
                        alert("An error occered, " + errorThrown);
                    }
                });
                break;
        }
    });
}


function addGMarker(ID, point, Marker_Icon) {
    icon = new GIcon(G_DEFAULT_ICON);

    if (_IconClientID == "0") {

            icon.image = "../../Images/Icons/ClientsIcons/" + _Speed_Icon;
        }
    }

    icon.iconSize = new GSize(32, 32);
    icon.dragCrossSize = new GSize(0, 0);
    icon.shadowSize = new GSize(32, 32);
    icon.iconAnchor = new GPoint(5, 5);

这与从jQuery调用Javascript函数的代码相同。 一切正常。 问题出在代码的其他地方。

这可能不是确切的解决方案，但请注意不要偏离解决方案。

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);
        }
    });
}
