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;

return;
}

window.SelectedState = {};
activeForm.BindUI(window.SelectedState);

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！

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}。
