getElementsByTagName()方法 返回带有指定标签名的节点对象的集合。返回元素的顺序是它们在文档中的顺序。...语法: document.getElementsByTagName(Tagname) 说明: 1. Tagname是标签的名称，如p、a、img等标签名。 2....看看下面代码，通过getElementsByTagName()获取节点。
使用getElementsByTagName获取元素 可以使用内置对象document上的getElementsByTagName方法来获取页面上的某一种标签，获取的是一个选择集，不是数组，但是可以用下标的方式操作选择集里面的标签元素... window.onload = function(){ var aLi = document.getElementsByTagName... window.onload = function(){ var aLi = document.getElementsByTagName

闭包演示 function init() { var pAry = document.getElementsByTagName(“p”); for( var i=0; i pAry[i].onclick...; } } } 产品一 产品二 产品三 产品四 产品五 解决方式有两种， 1、将变量 i 保存给在每个段落对象(p)上 function init() { var pAry = document.getElementsByTagName...onclick = function() { alert(this.i); } } } 2、将变量 i 保存在匿名函数自身 function init2() { var pAry = document.getElementsByTagName...alert(arg); }; })(i);//调用时参数 } } 4、加一层闭包，i以局部变量形式传递给内存函数 function init4() { var pAry = document.getElementsByTagName...alert(temp); } })(); } } 5、加一层闭包，返回一个函数作为响应事件(注意与3的细微区别) function init5() { var pAry = document.getElementsByTagName
