在jQuery中选择具有不同ID名称或类名称的元素中的元素

Question

我有一个有表的无序列表。 该列表还使用图像，当单击该图像时应隐藏该表。 我有以下jQuery代码，但无法正常工作：

$(".glyphicon-remove").click(function () {
        var tblId = $(this).attr("id");
       // alert(tblId);
       var ans = confirm("Are you sure you want to remove this table?");
       if(ans == true)
        $("#" + tblId).hide();
    });

并且使用的列表如下：

<ul class="sortable">
            <li class="ui-state-default"  id="first"><span style="float:right;"class="glyphicon glyphicon-remove"></span><br/>




            <table class="rounded-corner">

            <th></th>

请帮帮我。

Answer 1

您可以使用：

var tblId = $(this).parent().attr("id");

代替：

var tblId = $(this).attr("id");

因为你想要得到的id的li元素不span带班glyphicon-remove

Answer 2

尝试这个：

$(".glyphicon-remove").click(function () {
    var tblId = $(this).attr("id");
   // alert(tblId);
   var ans = confirm("Are you sure you want to remove this table?");
   if(ans == true)
    $(this).siblings('table').hide();
});
