获取JavaScript对象文字中键的同级值 [英] Getting sibling value of key in a JavaScript object literal

问题描述

有人知道有一种方法可以在JavaScript对象文字中引用同级键的值吗?

Does anybody know of there's a way to reference the value of a sibling key in a JavaScript object literal?

因此请在此处的beforeNext()函数中使用target的值:

so use the value of target in the beforeNext() function here:

obj: {
        target: 'li.player a.icon-tag',
        parent: 'ul#drop_list',
        beforeNext: function(){
          target.addClass('bind active');
        }
      }

推荐答案

这不是"JSON"对象，而是JavaScript对象(或仅仅是"Object").我认为这也包含在对象文字中，因为obj: {本身是无效的语法.

This is not a "JSON" object, but a JavaScript Object (or just "Object"). I assume that this is also contained in an Object literal as obj: { by itself is invalid syntax.

无论如何，是的，您可以使用this在方法中引用对象的属性.

Anyway, yes you can reference properties of an object in methods with this.

beforeNext: function () {
    this.target;
}
