请问列表中多条数据更新怎么做啊?有例子最好 将两种数据分别放到两个List中,在页面上将List中的内容按其在List中下标序列出,这样就可以用JavaScript操作其下标来实现左右移动,待提交时,后台提取参与移动的下标号列表,就可以确定移动的是那些数据,以及从哪个List移出 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 给你段代码,自己改动改动就行。让他onclick事件放到你自己移动按钮上,移动同时删除被移动栏的,就等于那个删除功能。<html><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312"><meta name="GENERATOR" content="Microsoft FrontPage 4.0"><meta name="ProgId" content="FrontPage.Editor.Document"><title>可选内容</title><SCRIPT LANGUAGE="JavaScript"><!-- Beginfunction moveOver() {var boxLength = document.choiceForm.choiceBox.length;var selectedItem = document.choiceForm.available.selectedIndex;var selectedText = document.choiceForm.available.options[selectedItem].text;var selectedValue = document.choiceForm.available.options[selectedItem].value;var i;var isNew = true;if (boxLength != 0) {for (i = 0; i < boxLength; i++) {thisitem = document.choiceForm.choiceBox.options[i].text;if (thisitem == selectedText) {isNew = false;break; } }} if (isNew) {newoption = new Option(selectedText, selectedValue, false, false);document.choiceForm.choiceBox.options[boxLength] = newoption;}document.choiceForm.available.selectedIndex=-1;}function removeMe() {var boxLength = document.choiceForm.choiceBox.length;arrSelected = new Array();var count = 0;for (i = 0; i < boxLength; i++) {if (document.choiceForm.choiceBox.options[i].selected) {arrSelected[count] = document.choiceForm.choiceBox.options[i].value;}count++;}var x;for (i = 0; i < boxLength; i++) {for (x = 0; x < arrSelected.length; x++) {if (document.choiceForm.choiceBox.options[i].value == arrSelected[x]) {document.choiceForm.choiceBox.options[i] = null; }}boxLength = document.choiceForm.choiceBox.length; }}function saveMe() {var strValues = "";var boxLength = document.choiceForm.choiceBox.length;var count = 0;if (boxLength != 0) {for (i = 0; i < boxLength; i++) {if (count == 0) {strValues = document.choiceForm.choiceBox.options[i].value;}else {strValues = strValues + "," + document.choiceForm.choiceBox.options[i].value;}count++; }}if (strValues.length == 0) {alert("您没有选择任何内容");}else {alert("您选择的内容如下:\r\n"+"第" + strValues+"条"); }}// End --></script></head><body><center><form name="choiceForm"><table border=0><tr> <td valign="top" width=175> <div align="center">可选内容:<br> <select name="available" size=10 onchange="moveOver();"> <option value="1">内容一</option> <option value="2">内容二</option> <option value="3">内容三</option> <option value="4">内容四</option> <option value="5">内容五</option> <option value="6">内容六</option> <option value="7">内容七</option> <option value="8">内容八</option> <option value="9">内容九</option> <option value="10">内容十</option> </select> </div> </td> <td valign="top"> <div align="center">你的选择:<br> <select multiple name="choiceBox" style="width:150;" size="10"> </select> </div> </td></tr><tr> <td colspan=2 height=10> <div align="center"> <input type="button" value="删除" onclick="removeMe();"> <input type="button" value="结果" onclick="saveMe();"> </div> </td></tr></table></form></center></body></html> 先谢谢大家~ 不过,用select功能上还不太够,希望每一条数据项都是多选框+文字链接的形式,通过多选框是否选中来移动对应项,点击链接还能出现那条数据的具体信息,请问有没有方法? 求解,部署的AIX的JAVA web程序无法遍历出文件 dtree一个技术问题,急切!!! struts + hibernate 框架 遭遇 大数据量 jsp页面自动跳转问题! 急!!! 类似网易的新闻栏目怎么设计? 请问JAVA中能否对结果集作二次检索? 100分求一个STRUTS方面的项目 各位帮我出个主意,很郁闷~~ 请教关于Servlet的响应返回的问题 关于spring-boot 请问struts和jstl各需要那些jar? 如何判断客户端的屏幕的分辩率??
