Question

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收到此错误：“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[]时，您可以用逗号分隔各个元素。但是在[a, b, c,]之类的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。

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!!!!
});

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"}
    }
});

我知道这是前一段时间被问过的，但这可能会有所帮助。如果您通过JSLint运行JavaScript，它会告诉您是否有任何“额外逗号”。
