IE9预期的标识符，字符串或数字错误

Question

我在IE9中得到上述错误，我看不出为什么会发生这种情况。我试图找到解决这个问题的方法，但我处于死胡同。有人可以指出我出错的地方吗？起初我认为这可能是最后一个逗号，但并非如此。由于

jQuery代码

$.validator.setDefaults ({ 

     errorClass: 'form_error', 
     errorElement: 'div' 
    }); 

    $("#BA_boxform").validate({ 
     rules: { 
      BA_customer: { 
       required: true 
      }, 
      customerdept: { 
       required: true 
      }, 
      customeraddress: { 
       required: true 
      }, 
      BA_service: { 
       required: true 
      }, 
      BA_box: { 
       required: true 
      }, 
      BA_destdate: { 
       required: true 
      }, 
      BA_authorised: { 
       required: true 
      } 
     }, 
     messages: { 
      BA_customer: { 
       required: '<br />* required: You must select a customer' 
      }, 
      customerdept: { 
       required: "<br />* required: You must select a department" 
      }, 
      customeraddress: { 
       required: "<br />* required: You must select a customer address" 
      }, 
      BA_service: { 
       required: "<br />* required: You must select a service level" 
      }, 
      BA_box: { 
       required: "<br />* required: You must enter a box number for intake" 
      }, 
      BA_destdate: { 
       required: "<br />* required: You must enter a destruction date" 
      }, 
      BA_authorised: { 
       required: "<br />* required" 
      } **<--- error is reported here** 
     }, 
    }); 

Answer 1

问题是与后面的逗号：

 } **<--- error is reported here** 
    }, <--- problem is here 

Answer 2

在messages属性中删除逗号。数组中的最后一个元素不应该包含逗号，否则IE会抛出错误。

$("#BA_boxform").validate({ 
    rules: { 
     // rules 
    }, 
    messages : { 
     // messages. 
    }, // REMOVE THE TRAILING COMMA 
}); 

应改为

$("#BA_boxform").validate({ 
    rules: { 
     // rules 
    }, 
    messages : { 
     // messages. 
    } 
}); 

Answer 3

messages: { 
      BA_customer: { 
       required: '<br />* required: You must select a customer' 
      }, 
      customerdept: { 
       required: "<br />* required: You must select a department" 
      }, 
      customeraddress: { 
       required: "<br />* required: You must select a customer address" 
      }, 
      BA_service: { 
       required: "<br />* required: You must select a service level" 
      }, 
      BA_box: { 
       required: "<br />* required: You must enter a box number for intake" 
      }, 
      BA_destdate: { 
       required: "<br />* required: You must enter a destruction date" 
      }, 
      BA_authorised: { 
       required: "<br />* required" 
      } **<--- error is reported here** 
     }, // <- Problem is here 

删除最后Comma.It应该正常工作。
