如何獲取所有復選框：document.getElementsByName、
需求分析
在我們對表格處理的時,有些情況下,我們需要對表格進行批量處理
技術分析
第一種方法：選擇器[屬性名稱='屬性值']
$("input[type='checkbox']:gt(0)").prop("checked",this.checked);
第二種方法：使用層級選擇器來實現 tbody > tr > td > input
$("tbody > tr > td > input").prop("checked",this.checked);
第三種方法：
// #tab > tbody > tr:nth-child(4) > td:nth-child(1) > input[type="checkbox"]
代碼實現
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<script type="text/javascript" src="../js/jquery-1.11.0.js" ></script>
<script>
/*
表格全選和全不選
進一步確定事件: 點擊事件
*/
$(function(){
//綁定點擊事件
//this 代表的是當前函數的所有者
$("#checkAll").click(function(){
//獲取當前選中狀態
// alert(this.checked);
//獲取所有分類項的checkbox
// 選擇器[屬性名稱='屬性值']
// $("input[type='checkbox']:gt(0)").prop("checked",this.checked);
//使用層級選擇器來實現 tbody > tr > td > input
// $("tbody > tr > td > input").prop("checked",this.checked); //這個可行
// #tab > tbody > tr:nth-child(4) > td:nth-child(1) > input[type="checkbox"]
$("input").prop("checked",this.checked);
});
});
