Javascript中的“变量”变量? 7个答案

I'm trying to get a dynamic attribute value to be used as a var name What I have:

我正在尝试将动态属性值用作var名称我拥有的内容:

$(this).html(""+$(this).attr("id")+"");

It gives me the value as plain text. What I want is that it uses the attr("id") value as a Var like:

它给了我纯文本的价值。我想要的是它使用attr(“id”)值作为Var,如:

$(this).html(""+myVar+"")

Final example:

<div class="text" id="text1"></div>
<div class="text" id="text2"></div>


var text1 = "hello world"
var text2 = "bye world"
$(document).ready(function () {
   $(".text").click(function(){
      $(this).html(""+$(this).attr("id")+"");  
   });
});

Basically I want a dynamic way of calling to certain id's and getting their attribute value to be used as the Var name instead of plain text.

基本上我想要一种动态的方式来调用某些id并将它们的属性值用作Var名称而不是纯文本。

It all depends on variable namespace and scope, but generally next code should do the job.

这一切都取决于变量名称空间和范围,但通常下一个代码应该完成这项工作。

$(".text").click(function(){
    var varFromAttr = window[$(this).attr("id")];
    $(this).html(varFromAttr);
});

Question is almost the same as this question.

问题与这个问题几乎相同。
