尾随逗号问题，javascript

我正在努力让我的jQuery在IE7中工作，当我发现以下内容时：

$(".regflow").validate({ errorLabelContainer: $("#error-message"), rules: { txtTextOnly: {required: true,textOnly: true}, txtNumbersOnly: {required: true,numbersOnly: true}, txtPhoneOnly: {required: true,phoneOnly: true}, txtAreaCodeOnly: {required: true,numbersOnly: true}, txtSimCodeOnly: {required: true,simCodeOnly: true}, txtCprOnly1: {required: true,numbersOnly: true}, txtCprOnly2: {required: true,cprOnly1: true}, txtMailOnly: {required: true,mailOnly: true} }, messages: { txtTextOnly: {required: "Dette felt skal udfyldes"}, txtNumbersOnly: {required: "Dette felt skal udfyldes"}, txtPhoneOnly: {required: "Dette felt skal udfyldes"}, txtAreaCodeOnly: {required: "Dette felt skal udfyldes"}, txtSimCodeOnly: {required: "Dette felt skal udfyldes"}, txtCprOnly1: {required: "Dette felt skal udfyldes"}, txtCprOnly2: {required: "Dette felt skal udfyldes"}, txtMailOnly: {required: "Dette felt skal udfyldes"} }, }); 

…我从Lint得到这个错误： “警告：尾随逗号在ECMA-262对象初始值设定项中不合法”

有谁知道这意味着什么，我该如何解决？

Answer 1

删除尾随逗号 – 以下部分末尾的逗号：

  messages: { txtTextOnly: {required: "Dette felt skal udfyldes"}, txtNumbersOnly: {required: "Dette felt skal udfyldes"}, txtPhoneOnly: {required: "Dette felt skal udfyldes"}, txtAreaCodeOnly: {required: "Dette felt skal udfyldes"}, txtSimCodeOnly: {required: "Dette felt skal udfyldes"}, txtCprOnly1: {required: "Dette felt skal udfyldes"}, txtCprOnly2: {required: "Dette felt skal udfyldes"}, txtMailOnly: {required: "Dette felt skal udfyldes"} }, 

在创建对象{}或数组[] ，可以使用逗号分隔各个元素。 但是在[a, b, c,]等最后一项之后还有一个额外的逗号 – 根据ECMA-262不允许这样做。

Answer 2

底部附近的额外逗号：

 $(".regflow").validate({ errorLabelContainer: $("#error-message"), rules: { txtTextOnly: {required: true,textOnly: true}, txtNumbersOnly: {required: true,numbersOnly: true}, txtPhoneOnly: {required: true,phoneOnly: true}, txtAreaCodeOnly: {required: true,numbersOnly: true}, txtSimCodeOnly: {required: true,simCodeOnly: true}, txtCprOnly1: {required: true,numbersOnly: true}, txtCprOnly2: {required: true,cprOnly1: true}, txtMailOnly: {required: true,mailOnly: true} }, messages: { txtTextOnly: {required: "Dette felt skal udfyldes"}, txtNumbersOnly: {required: "Dette felt skal udfyldes"}, txtPhoneOnly: {required: "Dette felt skal udfyldes"}, txtAreaCodeOnly: {required: "Dette felt skal udfyldes"}, txtSimCodeOnly: {required: "Dette felt skal udfyldes"}, txtCprOnly1: {required: "Dette felt skal udfyldes"}, txtCprOnly2: {required: "Dette felt skal udfyldes"}, txtMailOnly: {required: "Dette felt skal udfyldes"} }, //<--- this one!!!! }); 

Answer 3

是不是在谈论：

  }, // This comma here? }); 

在倒数第二行？

Answer 4

从最后一行删除最后一个逗号：

 $(".regflow").validate({ errorLabelContainer: $("#error-message"), rules: { txtTextOnly: {required: true,textOnly: true}, txtNumbersOnly: {required: true,numbersOnly: true}, txtPhoneOnly: {required: true,phoneOnly: true}, txtAreaCodeOnly: {required: true,numbersOnly: true}, txtSimCodeOnly: {required: true,simCodeOnly: true}, txtCprOnly1: {required: true,numbersOnly: true}, txtCprOnly2: {required: true,cprOnly1: true}, txtMailOnly: {required: true,mailOnly: true} }, messages: { txtTextOnly: {required: "Dette felt skal udfyldes"}, txtNumbersOnly: {required: "Dette felt skal udfyldes"}, txtPhoneOnly: {required: "Dette felt skal udfyldes"}, txtAreaCodeOnly: {required: "Dette felt skal udfyldes"}, txtSimCodeOnly: {required: "Dette felt skal udfyldes"}, txtCprOnly1: {required: "Dette felt skal udfyldes"}, txtCprOnly2: {required: "Dette felt skal udfyldes"}, txtMailOnly: {required: "Dette felt skal udfyldes"} } }); 

Answer 5

我知道这是在不久前问的，但这可能会有所帮助。 如果您通过JSLint运行JavaScript，它将告诉您是否有任何这些“额外的逗号”。
