insertAdjacentHTML动态插入行
添加HTML内容与文本内容以前用的是innerHTML与innerText方法,最近发现还有insertAdjacentHTML和insertAdjacentText方法,这两个方法更灵活,可以在指定的地方插入html内容和文本内容。
insertAdjacentHTML方法:在指定的地方插入html标签语句
原型:insertAdajcentHTML(swhere,stext)
参数:
swhere: 指定插入html标签语句的地方,有四种值可用:
1. beforeBegin: 插入到标签开始前
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> <head> <script language="javascript"> function myfun() { var obj = document.getElementById("btn1"); obj.insertAdjacentHTML("afterEnd","<br><input name=\"txt1\">"); } </script> </head> <body> <input name="txt"> <input id="btn1" name="btn1" type="button" value="更多..." > </body></html>=============================<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 ><div id="paral" style="fontsize:6;color='#ff00ff'">原来的内容</div><hr></body></html>=================================<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"><HTML><HEAD><TITLE> New Document </TITLE><META NAME="Generator" CONTENT="EditPlus"><META NAME="Author" CONTENT=""><META NAME="Keywords" CONTENT=""><META NAME="Description" CONTENT=""></HEAD><BODY><script>var num=0;var No_sys=0;function Add_button(){if(No_sys<8){ c_input.insertAdjacentHTML("beforeEnd","<div id=\"bar"+num+"\" oncontextmenu=\"Remove_button(bar"+num+");return false\" style=\"background:red;width:40;height:20\">"+num+"</div>"); num++; No_sys++;}}function Remove_button(obj){obj.removeNode(true);No_sys--;}</script><input type="button"value="动态加"><input type="button"value="看"><div id="c_input"></div></BODY></HTML>
