是将多个选择器分配给一个数组吗? [英] Is assigning multiple selectors into one var an array?

问题描述

是否将多个元素分配给一个数组中的变量?

Is assigning multiple elements into one variable considered an array?

var $myList = $("#elOne, #elTwo, #elThree, etc");

如果不是，那是什么?另外，在变量名中添加'$'只是为了提醒开发人员这是元素引用变量的标准做法吗?

If not, what is it? Also, is adding the '$' to the var name just standard practice to remind developers that this is an element reference variable?

推荐答案

$是为了提醒开发人员此变量保存对jQuery对象的引用.

$ is to remind developers that this variable holds reference to a jQuery object.

是的，$myList将把选择器应用到的所有元素作为数组保存(尽管它是一个jquery对象，但它像数组一样保存它们)

And Yes, $myList will hold all the element that your selector applied to as an array(although it's a jquery object it just holds them like an array)
