javascript - 如何在JS中创建动态变量？

Question

这是我的代码:

function NewPerson() {
    var count = parseInt($('#HiddenField').html());
    count++;
    $('#HiddenField').html(count);
    Var dynamicVariable = 'Person'+'Count' 
}

我想在这一行定义变量Var **dynamicVariable** = 'Person'+'Count'

现在我需要创建带有计数的变量

你也可以尝试这个。

  var count = 1; //Let this be your count variable.
  var PersonString = "Person" + count; //Building a dynamic name for your variable
  alert(PersonString); //Person1 will be alerted
  window[PersonString] = "One";
  alert(Person1); //One will be alerted.

P.S : Here variables created dynamically will have a global scope.
