jQuery 查找父元素
function deletesec1Div5(obj){
$(obj).closest(".sec1-div5").remove();
}
自己写的一段代码，实现了table中的全选，反全选，删除功能。
HTML代码如下：
<section class="sec1 container"><!--请假管理--->
<div class="row container-fluid sec1-head">
<h4 class="col-lg-6 ">学生请假明细表</h4>
<div class="col-lg-6">
<!--<div class="myfont1 close1 pull-right"></div>-->
<div class="myfont1 down-arrow pull-right"></div>
</div>
</div>
<div class="container sec1-Sch"><!--搜索框--->
<div class="row">
<div class="col-lg-4">
<a href="add_leaveInfo.html" class="btn btn1">添加请假信息+</a>
</div>
<div class=" sec1-search col-lg-8 ">
<span class="myfont1 sec1-search-icon pull-right"></span>
<input type="text" placeholder="学号..." class="form-control sec1-input pull-right"/>
<input type="text" placeholder="学生姓名..." class="form-control sec1-input pull-right"/>
<span class="pull-right">搜索：</span>
</div>
</div>
</div>
<div class="container">
<div class="row">
<div class="table-responsive">
<table class="table table-striped table-bordered ">

<script>
$(function(){ //考勤中的全选和反全选 $("#selectAll").click(function(){ $(".sec1-checkBox").prop("checked",true); }); $("#Unselect").click(function(){ $(".sec1-checkBox").prop("checked",false) }); //考勤管理中的删除 $("#sec1-Del").click(function () { $(".sec1-checkBox").each(function () { if ($(this).prop("checked")==true) { // $(this).parent().parent().remove(); // console.log($(this).parent().parent()); $(this).closest("tr").remove(); } }); }); //请假管理中的全选和反全选 $("#sec2-selectAll").click(function(){ $(".sec2-checkBox").prop("checked",true); }); $("#sec2-Unselect").click(function(){ $(".sec2-checkBox").prop("checked",false) }); //请假管理中的删除 $("#sec2-Del").click(function () { $(".sec2-checkBox").each(function () { if ($(this).prop("checked")==true) { // $(this).parent().parent().remove();//这是查找父元素的另一种写法，和代码的结构有关 $(this).closest("tr").remove(); } }); }); })
