昨天自己写了一小段js，在全选的时候有点儿小坑，然后，整理了一下。今天把它贴出来，希望以后还记得。

我在用angular实现表格的全选时，是给了一个标记--就是一个空数组，每次有个别项选中，我都会push一个数字，当有选项从选中状态到未选中变化时，我就让该数组弹出一个数字。这样就可以实现了。我实现的个别删除和全部删除是从页面删除的，并没有操作json对象，因此，在真正项目中使用的话，还需要加上ajax请求，同时删除服务器上的数据。
代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>表格的全选，删除</title>
<link rel="stylesheet" href="../css/bootstrap.min.css"/>
<style type="text/css">
table th {
text-align: center;
}
input[type="checkbox"] {
width: 20px;
height: 20px;
}
</style>
</head>
<body ng-app="myApp" ng-controller="myCtrl">
<table border="" cellspacing="" cellpadding="" class="table" style="text-align: center;">
<tr>
<th><input type="checkbox" ng-model="selectedAll" ng-click="selectAll()"/></th>
<th>姓名</th>
<th>年龄</th>
<th>性别</th>
<th>民族</th>
<th ng-click="delAll($event)" style="cursor:pointer">全部删除</th>
</tr>
<tr ng-repeat="item in items">
