将JavaScript for-循环集成到自定义函数中

Question

我有一个工作的EcmaScript-3函数，它将数组转换成特定的字符串格式。

阵列：

ft: [
    1: {name: "gender", value: "F", focus: 0, type: "radio"}
    2: {name: "firstname", value: "empty", focus: 0, type: "text"}
    3: {name: "lastname", value: "empty", focus: 0, type: "text"}
    4: {name: "birthday", value: "empty", focus: 0, type: "text"}
    5: {name: "street", value: "empty", focus: 0, type: "text"}
    6: {name: "streetNo", value: "empty", focus: 0, type: "text"}
]

特定字符串格式：

ft=gender.radio|F|0;firstName.text|empty|1;lastName.text|empty|0;street.text|empty|0;houseNumber.text|empty|0;zip.text|empty|0;city.text|empty|0;country.select-one|de|0;birthdate-day.text|empty|0;birthdate-month.text|empty|0;birthdate-year.text|empty|0;email.email|empty|0;code.text|filled_out|0

将数组转换为特定字符串格式的工作函数：

var arr = [];
for (var i = 0; i < ft.length; i++) {
    var elem = ft[i];
    arr.push(elem.name + "." + elem.type + "|" + elem.value + "|" + elem.focus);
}
var str = arr.join(";");

console.log(str);

问题：

我需要一个函数(以EcmaScript-3格式)，可以这样调用：

var a = tracking()(ft, false);
console.log(a); 

// the console.log(a) should provide as a result: ft=gender.radio|F|0;firstName.text|...; false;

我的解决方案(不起作用)

function tracking() {
  return function (ft, submitted) {
     var arr = [];
     for (var i = 0; i < ft.length; i++) {
       var elem = ft[i];
       arr.push(elem.name + "." + elem.type + "|" + elem.value + "|" + 
       elem.focus + "submitted");
     }
     var str = arr.join(";");
  }
}

谢谢!

看来你把事情搞得太复杂了。这件事可以这么简单

function tracking (ft, submitted) {
  var arr = [];
  for (var i = 0; i < ft.length; i++) {
    var elem = ft[i];
    arr.push(elem.name + "." + elem.type + "|" + elem.value + "|" + 
    elem.focus + "submitted");
  }
  return arr.join(";");
}

我也不知道你为什么会收到那封信。如果要将其用作变量，只需删除引号，同时将其推送到数组中即可。
