jquery对table中各数据的增加、保存、删除操作示例

<input name="button" type="button" value="添加" onClick="addRowForPswdBasicFillTemplate('pswd_basic_fill_template')">

function addRowForPswdBasicFillTemplate(tid){
var applyAreaOptionStr = $('#applyAreaOptionStr').val(); //这里是对select框的一些初始化
did = tid;
var tr = $("<tr></tr>").attr("bgcolor","#FFFFFF");
tr.append($("<td></td>").html("<input type='radio' name='radio' value='checkbox'></td>"));

前台的操作就完成了，下面看一看后台的操作
struts配置文件
<method name="save" uri="/secbasicFillTemplate/save">
<result name="success" type="redirect">@list</result>
<result name="failed">secassessment/basicFillTemplate/basicFillTemplateNew</result>
</method>
后台操作
public void save() {
String obj = request().getParameter("tempLateList");
List<SecBasicFillTemplate> result = JSonUtil.paserJsonArray(SecBasicFillTemplate.class,obj);
//将json转化为对象
}
下面看看删除操作
删除按钮 <input name="button" type="button" value="删除" onClick="delRowForSpacialById('pswd_basic_fill_template')" >
//删除一行的数据
function delRowForSpacialById(tid){
var selObj=getSelRowJnSpacial(tid);
if(selObj){
var result = confirm("确定将记录删除？");
if(result){
var id = selObj.parent().parent();
var idValue = id.find("input[name='idObj']").val();
if(idValue!=null && idValue.length>0){
$.post("<c:url value='/secbasicFillTemplate/delete'/>",{"ids":idValue},function(){
selObj.parent().parent().remove();
})
}else{
selObj.parent().parent().remove();
}
}
}
}
// 获取选中的行
function getSelRowJnSpacial(tid){
var selObj=eval("$(\"#"+tid+" input[@type=radio][checked]\")");
if(selObj.html()!=null){
return selObj;
}else{
showInfo("请选择要操作的行");
return null;
}
}
struts 配置文件
<method name="delete" uri="/secbasicFillTemplate/delete" >
<result name="success" type="redirect">@list</result>
</method>
后台方法
public void delete(String ids) {
//方法
}
上移下移功能
按钮
<input name="button" type="button" value="上移" onClick="moveBefore('pswd_basic_fill_template')">
<input name="button" type="button" value="下移" onClick="moveAfter('pswd_basic_fill_template')">
//上移行

did =tid;

if(parseInt(rowIndex)<=2){
showInfo("已经到顶,不能再上移了");
return;
}
var preObj=selObj.parent().parent().prev();
var selRow=selObj.parent().parent().clone();
preObj.before(selRow);
selObj.parent().parent().remove();
setRowNumber_1_1(did);
}
}
function setRowNumber_1_1(tid){
var fNew = 1;
var expression="$(\"#"+tid+" tbody tr\")";
var tbody=eval(expression);
$.each(tbody,function(i,tr){
if(i>=0){
var number=i+1;
$(tr).find("td:nth-child(2)").text(number);
}
})
}
//下移行
function moveAfter(tid){

}else{

return;
}
var nextObj=selObj.parent().parent().next();
var selRow=selObj.parent().parent().clone();
nextObj.after(selRow);
selObj.parent().parent().remove();
setRowNumber_1_1(tid);
}
}
//设置rowNumber的序号
function setRowNumber_1(tid){
var fNew = 1;
var expression="$(\"#"+tid+" tbody tr\")";
var tbody=eval(expression);
$.each(tbody,function(i,tr){
