如何在jQuery中为数组使用$ .each方法？

Question

function calcTotalScore(){
    var arr = ["A","B","C","D","E","F"];
    $.each(arr, function(n,val){
        calcTotal(val);
    });
}

calcTotal(value){
// sample code
}

我在速度模板语言（VTL）中使用上述函数calcTotalScore()，但它说：

Encountered "," Was expecting one of:
   <EOF> 
    "(" ...
   <RPAREN> ...
   <ESCAPE_DIRECTIVE> ...
   <SET_DIRECTIVE> ...
   "##" ...
   "\\\\" ...
   "\\" ...
   <TEXT> ...
   "*#" ...
   "*#" ...
   <STRING_LITERAL> ...
   <IF_DIRECTIVE> ...
   <STOP_DIRECTIVE> ...
   <INTEGER_LITERAL> ...
   <FLOATING_POINT_LITERAL> ...
   <WORD> ...
   <BRACKETED_WORD> ...
   <IDENTIFIER> ...
   <DOT> ...
   "{" ...
   "}" ...

我做错了什么？

Answer 1

VTL将jQuery的$解释为变量的开头。然后它抱怨，因为变量名称不能以点开头。

您有两种选择：

1. 以反斜杠逃避美元，例如。 \$
2. 使用jQuery代替$

你只是在calcTotal前面缺少一个“函数”;）

function calcTotalScore(){
    var arr = Array("A","B","C","D","E","F");
    $.each(arr, function(n,val){
        calcTotal(val);
    });
}

function calcTotal(value){
// sample code
    alert(value);
}

calcTotalScore();
