Question

所以我在JS中输入了意想不到的结尾，它在第1行，我真的无法理解它是什么，这里是代码：

window.HandlePageCommand = function (commandName) {

    document.getElementById("buffer").innerHTML = commandName + " | " + window.ActiveForm.Name;
    var activeForm = window.ActiveForm;
    var call;
    var callback;
    var requestData;
    var grid;

    if (commandName === "CANCEL") {
        Exertus.MainModalPanel.Hide();
        return;
    }

    if (commandName === "ADD_PERIOD") {

        target = activeForm.Sections[1];
        window.SelectedState = {};
        activeForm.BindUI(window.SelectedState);
        grid = window.RegisteredControls.Grids["Semestres"];

        grid.AddedEntities = [];
        grid.DeletedEntities = [];
        grid.Databind([]);

    }

            Exertus.MainModalPanel.ShowText("Notificación", "Se han cancelado los cambios.");
        }

        var grid = window.RegisteredControls.Grids["Carga De Archivos"];
        callback.Grid = grid;
        Exertus.MainModalPanel.Confirm("Confirmación", "¿Confirma que desea cancelar los cambios?", callback);
    }

}

错误标记在第一行，第一行是空的，所以我不知道那是什么。

我的另一个问题是Chrome说我没有定义一个功能，但是我想在我需要定义的所有文档中定义它，你能告诉我是否有任何工具可以帮助我找出它没有定义的地方？谢谢！

Answer 1

对于代码段中的所有{，它都会在5 }左右丢失。

这会创建一个SyntaxError，因为解析器正在尝试匹配每对，并且在它可以之前用完代码（因此，“意外结束”）。此错误还会使function定义无效，这就是为什么它可能尝试使用它的其他代码不存在。

要获得帮助的工具，您可以尝试JSHint。它可能有些严格，但会扫描一段代码并记下它认为有用的任何建议。并且，它是可配置的，因此扫描复选框列表以调整它给出的警告类型。

尽管如此，最好的猜测是他们开始缺席：

if (commandName === "GUARDAR") {

    if (activeForm.Name === "Factores de Venta 1") {
        var callback = function (responseData) {
            window.OriginalFactors = jQuery.extend({}, window.FactorsInfo);
            window.SetLoading(false);
            Exertus.MainModalPanel.ShowText("Notificación", "Se han guardado los cambios.");
        }

        if (window.ActiveForm.Validate() != true) {
            return;
        }

        window.SetLoading(true);
        var call = new Exertus.ServerCall("MainWebModule");
        window.FactorsInfo = window.FactorsInfo || {};
        activeForm.BindEntity(window.FactorsInfo);
        call.Execute("SaveFactors", window.FactorsInfo, callback);
        return;
    }

//} <-- missing

我想你忘记了一个括号，看看附近的代码：

if (commandName === "DISCARD_CHANGES") {
var callback = function () {

就我所见，if语句没有关闭}。

意外的输入结束（第1行）和未定义的功能？
