我想实现以下目标
1）单击.step2-opt
2）.quiz__drawer div应获取.step2info的高度
3）HTML输出应为
<div class="quiz__drawer" style="height:height of .step2info div">
4）使用以下jQuery代码
$('body').on("click", '.step2-opt', function () {
$(".quiz__drawer").height(function(){
$(".step2info").outerHeight();
});
});
请帮助我修复jquery代码。
这里有一个例子供你尝试，希望能有所帮助
null
$('body').on("click", '.step2-opt', function () {
// get the height of step2info
var height = $('.step2info').css("height");
// set the height of quiz__drawer
$('.quiz__drawer').css("height", height)
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="step2info" style="height: 200px; width: 200px; background-color: red;"></div>
<div class="quiz__drawer" style="height: 100px; width: 200px; background-color: green;"></div>
<button class="step2-opt">set height</button>
如您所见，在单击first div:
null
$.fn.equalizeHeights = function(){
return this.height( Math.max.apply(this, $(this).map(function(i,e){ return $(e).height() }).get() ) )
}
function test(){
$('.step2info, .quiz__drawer').equalizeHeights();
}<script
