jQuery中可以通过append在列表的最后添加数据,也可以通过prepend在列表的最前面添加数据
方法很简单:
另外附上jquery实现连续向textarea文本域添加数据的代码。
- <%@ page language="java" contenttype="text/html; charset=gbk" pageencoding="gbk"%>
- <%@ include file="/pages/common/taglibs.jsp"%>
- <!doctype html public "-//w3c//dtd html 4.01 transitional//en" "http://www.w3.org/tr/html4/loose.dtd">
- <html>
- <head>
- <script type="text/javascript" src="jquery-1.4.js"></script>
- <script type="text/javascript">
- $(document).ready(function(){
- $("input[id^='buttonvalidate']").click(function(){ //当点击所有的id中包含'buttonvalidate'的input标签时,执行函数
- var btnval=$.trim($(this).val());//trim函数,去掉空格
- var str = $('#textareavalidate').val() + btnval;//
- $('#textareavalidate').val(str);//
- });
- });
- </script>
- <title>insert title here</title>
