js中insertAdjacentHTML的玩法
原型:insertAdajcentHTML(swhere,stext) insertAdjacentHTML方法:在指定的地方插入html标签语句 2.afterBegin:插入到标签开始标记之后 3.beforeEnd:插入到标签结束标记前 4.afterEnd:插入到标签结束标记后 stext:要插入的内容 <html> |
这个例子可以更直观的查看它们的作用:
<head>
<title>24.htm insertAdjacentHTML插入新内容</title>
<script language="jscript">
function addsome()
{
document.all.paral.insertAdjacentHTML("afterBegin","<h1>在文本前容器内插入内容</h1>");
document.all.paral.insertAdjacentHTML("beforeEnd","<h2>在文本后容器内插入内容</h2>");
document.all.paral.insertAdjacentHTML("beforeBegin","<h4>在文本前容器外插入内容</h1>");
document.all.paral.insertAdjacentHTML("afterEnd","<h5>在文本后容器外插入内容</h2>");
}
</script>
</head>
<body onload="addsome()">
<div id="paral" style="fontsize:6;color='#ff00ff'">原来的内容</div><hr>
</body>
</html>
