<label class="js_highlight" style="display: inline-block;float: left;width: 50%;">                             <div class="compare-top-left-check">                                 <label class="label-check"><i style="display: none;"></i></label>                                 <span style="margin-left: 20px;"> Hide different items</span>                             </div>                         </label>

js:  以上代码在电脑浏览器和安卓上都能触发alert事件，但是在ios上却完全没有反应

1 2	$(document).on("click",".js_equal_hide",function(){     var n=~~$(".JS_numshow").html().split("/")[0];

修改js代码调试： 将两层的div都加上点击事件

$(".js_equal_hide .compare-top-left-check").click(function () {     var n=parseInt($(".JS_numshow").html().split("/")[0]);         if(n<2)return false;     var $this = $(this).parent();
