如何从 jQuery 中的事件监听器 function 返回值

Question

I am having difficulty returning a value from an event listener function and storing it in a variable.我很难从事件侦听器 function 返回值并将其存储在变量中。

What I did is as below, but I can not do this and I have no idea how to solve the problem.我所做的如下，但我不能这样做，我不知道如何解决这个问题。

 $(".container").click(function() { let color = $(".container").css("background-color"); //I want to return this color and store it in a variable. })

 .container { height: 50px; width: 50px; background-color: red; }

 <div class="container"></div>

Answer 1

I think this is what you are looking for我想这就是你要找的

var container = document.getElementById("myDivID")
var containerColor = window.getComputedStyle(container).backgroundColor;

Now you can return it via an alert or inserting it as html into another div.现在您可以通过警报将其返回或将其作为 html 插入另一个 div。
