本篇文章主要是對Jquery實現點擊按鈕,連續地向textarea中添加值的實例代碼進行了介紹,需要的朋友可以過來參考下,希望對大家有所幫助
代碼如下: 代碼如下: <%@ 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(){ $("input[id^='buttonValidate']").click(function(){ //當點擊所有的id中包含'buttonValidate'的input標簽時,執行函數 var btnVal=$.trim($(this).val());//trim函數,去掉空格 var str = $('#textareaValidate').val() + btnVal;// $('#textareaValidate').val(str);// }); }); </script> <title>Insert title here</title> </head> <body> <form id="form1" name="form1" action="" method="post"> <table id ="table1" class="base_table" cellspacing="0" border="1" style="border-collapse: collapse"> <tr> <td > <textarea cols="75" rows="5" id="textareaValidate"></textarea> </td> </tr> <tr id="tr1"> <td> <input id="buttonValidate1" type="button" value=" + "/> <input id="buttonValidate2" type="button" value=" - "/> <input id="buttonValidate3" type="button" value=" * "/> <input id="buttonValidate4" type="button" value=" / "/> <input id="buttonValidate5" type="button" value=" ! "/> <input id="buttonValidate6" type="button" value=" = "/> <input id="buttonValidate7" type="button" value=" < "/> <input id="buttonValidate8" type="button" value=" > "/> <input id="buttonValidate9" type="button" value=" & "/> <input id="buttonValidate10" type="button" value=" | "/> <input id="buttonValidate11" type="button" value=" ( "/> <input id="buttonValidate12" type="button" value=" ) "/> </td> </tr> </table> </form> </body> </html> 以上實現的功能:點擊+,則把+添加到textarea中,點擊-,則把-添加到textarea中;
