项目笔记：新增、编辑与删除

一、新增：

　　//添加序列号
function addSerialNumber(obj){
var type = $("input[name='serialNumber']:checked").val();
showWindow($(obj).attr("title"),"genuineSerialNumberManagementAction_addUI.do?genuineSerialNumberManagement.type="+type,"500","320",true);
}

1、后台新增：由于需要传入type来辨别是正版还是非正版，所以在 addUI 上需要将type get出来，然后传给前台页面，前台页面通过下面这样去获取

var type = '<s:property value="genuineSerialNumberManagement.type"></s:property>';

　　//新增序列号UI
public String addUI(){
if(genuineSerialNumberManagement.getType() != null && !"".equals(genuineSerialNumberManagement.getType())){
getRequest().setAttribute("type", genuineSerialNumberManagement.getType());
}
return RETURN_ADDUI;
}

2、addUI页面：表单里面需要加上隐藏域，否则后台那边收不到值

<form id="genuineSerialNumberManagementAction_add">
<table id="itemTable" align="center">
<tr><input type="hidden" id="type" name="genuineSerialNumberManagement.type"></tr>
<tr><input type="hidden" id="softId" name="genuineSerialNumberManagement.softId"></tr>
<tr>
<td class="rightAlign"><label>软件名：</label></td>
<td><input type="text" id="softDisplayName" name="genuineSerialNumberManagement.softDisplayName" class="inputText {required:true}" /> <label id='requiredLabel'>*</label></td>
</tr>
<tr>
<td class="rightAlign"><label>版本号：</label></td>
<td><input type="text" id="version" name="genuineSerialNumberManagement.version" class="inputText {required:true}" /> <label id='requiredLabel'>*</label></td>
</tr>
<tr>
<td class="rightAlign"><label>序列号：</label></td>
<td><input type="text" id="serialNumber" name="genuineSerialNumberManagement.serialNumber" class="inputText {required:true}" /> <label id='requiredLabel'>*</label></td>
</tr>
<tr style="line-height: 60px;">
<td colspan="2" align="center">
<button class="layerButton" id="buttonSubmit">
<span>提交</span>
</button>
<button class="layerButton" id="closeBT">
<span>取消</span>
</button>
</td>
</tr>
</table>
</form>

$(function(){
var type = '<s:property value="genuineSerialNumberManagement.type"></s:property>';
$("#type").val(type);
$("#softId").val(11223344);

$("#buttonSubmit").click(function(){
var softDisplayName = $("#softDisplayName").val(),
version = $("#version").val(),
softId = $("#serialNumber").val(),
type = $("#type").val(),
serialNumber = $("#serialNumber").val();
$("#genuineSerialNumberManagementAction_add").form("submit",{
method : "POST",
url : "genuineSerialNumberManagementAction_add.do?disc=genuineSerialNumberManagement_add&genuineSerialNumberManagement.softDisplayName="
+ escape(escape(softDisplayName)) + "&genuineSerialNumberManagement.version=" + escape(escape(version))
+ "&genuineSerialNumberManagement.serialNumber=" + escape(escape(serialNumber))
+ "&genuineSerialNumberManagement.type=" + type
+ "&genuineSerialNumberManagement.softId=" + softId,
timeout : 3000000,
success : function(data){
var jsondata = eval("(" + data + ")");
if(jsondata.msg == 'success'){
if(type == 1){
getDeskTopObj().$('#inside_tableElement').datagrid('insertRow',{
index:0,
row: {
id : jsondata.id,
softDisplayName : jsondata.softDisplayName,
version : jsondata.version,
serialNumber : jsondata.serialNumber
}
});
}else{
getDeskTopObj().$('#inside_tableElement_no').datagrid('insertRow',{
index:0,
row: {
id : jsondata.id,
softDisplayName : jsondata.softDisplayName,
version : jsondata.version,
serialNumber : jsondata.serialNumber
}
});
}
showMsg("", "添加成功！", true);
}else{
showMsg("", "添加失败！", false);
}
}
})
return false;//禁止表单提交事件，防止2次请求
})

});

注意表单提交的时候因为有默认的submit，所以请求会提交2次，需要阻止表单的默认提交事件。

3、后台新增功能：

　　//新增序列号
public void add(){
log.info("【正版序列号管理--新增序列号：开始】");
this.msg = RESULT_FAIL;
GenuineSerialNumberManagement temp = null;
String resultInfo = "";
try {
this.msg = RESULT_FAIL;
if(genuineSerialNumberManagement.getSoftDisplayName() != null && !"".equals(genuineSerialNumberManagement.getSoftDisplayName())){
genuineSerialNumberManagement.setSoftDisplayName(EscapeUnescape.unescape(genuineSerialNumberManagement.getSoftDisplayName()));
}
if(genuineSerialNumberManagement.getVersion() != null && !"".equals(genuineSerialNumberManagement.getVersion())){
genuineSerialNumberManagement.setVersion(EscapeUnescape.unescape(genuineSerialNumberManagement.getVersion()));
}
if(genuineSerialNumberManagement.getSerialNumber() != null && !"".equals(genuineSerialNumberManagement.getSerialNumber())){
genuineSerialNumberManagement.setSerialNumber(EscapeUnescape.unescape(genuineSerialNumberManagement.getSerialNumber()));
}
if(genuineSerialNumberManagement.getType() != null && !"".equals(genuineSerialNumberManagement.getType())){
genuineSerialNumberManagement.setType(genuineSerialNumberManagement.getType());
}
if(genuineSerialNumberManagement.getSoftId() != null && !"".equals(genuineSerialNumberManagement.getSoftId())){
genuineSerialNumberManagement.setSoftId(genuineSerialNumberManagement.getSoftId());
}
genuineSerialNumberManagementService.save(genuineSerialNumberManagement);
//自动生成xml
genuineSerialNumberManagementService.createXML();
this.msg = RESULT_SUCCESS;

temp = (GenuineSerialNumberManagement)BeanUtils.cloneBean(genuineSerialNumberManagement);
temp.setId(genuineSerialNumberManagement.getId());
resultInfo = "{\"msg\":\""+ this.msg +"\","
+ "\"id\":\"" + temp.getId() +"\","
+ "\"softDisplayName\":\"" + temp.getSoftDisplayName() +"\","
+ "\"version\":\"" + temp.getVersion() +"\","
+ "\"serialNumber\":\"" + temp.getSerialNumber()+"\"}";

} catch (Exception e) {
log.info("【正版序列号管理--新增序列号：新增失败】");
this.msg = RESULT_FAIL;
e.printStackTrace();
}finally{
print(resultInfo);
log.info("【正版序列号管理--新增序列号：结束】");
}
}

二、编辑：

　　//修改序列号
function editSerialNumber(obj){
var type = $('input[name="serialNumber"]:checked').val();
if(type == 1){
var rows = $("#inside_tableElement").datagrid('getSelections');
}else{
var rows = $("#inside_tableElement_no").datagrid('getSelections');
}
if (rows.length < 1) {
showAlertDialog("信息确认", "请选取记录！");
} else if (rows.length > 1) {
showAlertDialog("信息确认", "目前只支持单条记录删除，请去掉多选项！");
} else {
showWindow($(obj).attr("title"),"genuineSerialNumberManagementAction_editUI.do?genuineSerialNumberManagement.id="+rows[0].id,"500","320",true);
}
}

注意：编辑表单里面需要加上id，并且每行加上value，设置为库里的值，这样编辑的时候不至于为空

<form id="genuineSerialNumberManagementAction_edit">
<!-- ID -->
<input id="id" type="hidden" name="genuineSerialNumberManagement.id" value="<s:property value='genuineSerialNumberManagement.id'/>">
<table id="itemTable" align="center">
<tr></tr>
<tr></tr>
<tr>
<td class="rightAlign"><label>软件名：</label></td>
<td><input type="text" id="softDisplayName" name="genuineSerialNumberManagement.softDisplayName"
value="<s:property value='genuineSerialNumberManagement.softDisplayName' />" class="inputText {required:true}" /> <label id='requiredLabel'>*</label></td>
</tr>
<tr>
<td class="rightAlign"><label>版本号：</label></td>
<td><input type="text" id="version" name="genuineSerialNumberManagement.version"
value="<s:property value='genuineSerialNumberManagement.version' />" class="inputText {required:true}" /> <label id='requiredLabel'>*</label></td>
</tr>
<tr>
<td class="rightAlign"><label>序列号：</label></td>
<td><input type="text" id="serialNumber" name="genuineSerialNumberManagement.serialNumber"
value="<s:property value='genuineSerialNumberManagement.serialNumber' />" class="inputText {required:true}" /> <label id='requiredLabel'>*</label></td>
</tr>
<tr style="line-height: 60px;">
<td colspan="2" align="center">
<button class="layerButton" id="buttonSubmit">
<span>提交</span>
</button>
<button class="layerButton" id="closeBT">
<span>取消</span>
</button>
</td>
</tr>
</table>
</form>

$(function(){
$("#buttonSubmit").click(function(){
$.doAjax({
isSend : $("#genuineSerialNumberManagementAction_edit").valid(),
url : "${basePath}/genuineSerialNumberManagementAction_edit.do",
//dataType:"json",
data : $("#genuineSerialNumberManagementAction_edit").serialize(),
success : function(data) {
if (data == 'success') {
getDeskTopObj().editRow( {
softDisplayName : $("#softDisplayName").val(),
version : $("#version").val(),
serialNumber : $("#serialNumber").val()
});
showMsg("", "修改成功！", true);
} else {
showMsg("", "修改失败！", false);
}
},
error : function() {
showMsg("", "修改失败！", false);
}
});
return false;
});
});

编辑后台方法：通过id去查找到数据，然后把查到的数据更新为页面传过来的数据

　　//修改序列号
public void edit() {
log.info("【正版序列号管理--修改序列号：开始】");
this.msg = RESULT_FAIL;
try {
this.msg = RESULT_FAIL;
if (genuineSerialNumberManagement != null) {
GenuineSerialNumberManagement findGenuineSerialNumberManagement = genuineSerialNumberManagementService.queryById(genuineSerialNumberManagement.getId());
if (findGenuineSerialNumberManagement != null) {
findGenuineSerialNumberManagement.setSoftDisplayName(genuineSerialNumberManagement.getSoftDisplayName());
findGenuineSerialNumberManagement.setVersion(genuineSerialNumberManagement.getVersion());
findGenuineSerialNumberManagement.setSerialNumber(genuineSerialNumberManagement.getSerialNumber());
genuineSerialNumberManagementService.update(findGenuineSerialNumberManagement);
//自动生成xml，删除原有的重新生成
genuineSerialNumberManagementService.createXML();
this.msg = RESULT_SUCCESS;
}
}
} catch (Exception e) {
this.msg = RESULT_ERROR;
log.error("【正版序列号管理--修改序列号：修改失败】", e);
}finally{
print(this.msg);
log.info("【正版序列号管理--修改序列号：结束】");
}
}

三、删除

　　//删除序列号
function deleteSerialNumber(obj){
var type = $('input[name="serialNumber"]:checked').val();
var $table;
if(type == 1){
var trIds = getSelectedIds("#inside_tableElement");
$table = $("#inside_tableElement");
}else{
var trIds = getSelectedIds("#inside_tableElement_no");
$table = $("#inside_tableElement_no");
}
if (checkRecordSize(trIds, false)) {
var title = $(obj).attr("title");
showConfirmDialog(title, "删除后数据将无法恢复，您确定要删除吗?", function() {
$.doAjax({
url : "${basePath}/genuineSerialNumberManagementAction_delete.do",
data : {
"selectedIds" : trIds.join(";")
},
success : function(data) {
if (data == 'success') {
deleteRows();
showMsg("", "删除成功！", true);
$table.datagrid("reload");
}else{
showMsg("", "删除失败！", false);
}
},
error : function() {
showMsg("", "删除失败！", false);
}
});
});
}
}
　　//获取选中行的id
function getSelectedIds(id){
var ids = [];
var rows = $(id).datagrid('getSelections');
for(var i=0;i<rows.length;i++){
ids.push( jQuery.trim( rows[i].id ) );
}
return ids;
}

后台删除方法：

　　//删除序列号
public void delete() {
log.info("【正版序列号管理--删除序列号：开始】");
this.msg = RESULT_FAIL;
try {
this.msg = RESULT_FAIL;
Integer[] ids = new Integer[selectedIds.split(";").length];
if (selectedIds.length() > 0) {
String[] delIds = new String[selectedIds.split(";").length];//声明一个数组保存要删除的id
for (int i = 0; i < selectedIds.split(";").length; i++) {
delIds[i] = selectedIds.split(";")[i];
ids[i] = Integer.parseInt(String.valueOf(delIds[i]));
}
genuineSerialNumberManagementService.deleteByIds(ids);
// 自动生成xml，删除原有的重新生成
genuineSerialNumberManagementService.createXML();
this.msg = RESULT_SUCCESS;
}
} catch (Exception e) {
this.msg = RESULT_ERROR;
log.error("【正版序列号管理--删除序列号：删除失败】", e);
} finally {
print(this.msg);
log.info("【正版序列号管理--删除序列号：结束】");
}
}

我们可以看下deleteByIds，继承自BaseService，实现于BaseServiceImpl

　　@Override
public void deleteByIds(Integer[] ids) {
if (ids != null && ids.length == 1) {
baseDao.delete(ids[0]);
} else if (ids != null && ids.length > 0) {
baseDao.deleteByIds(ids);
}
}

　　@Override
public void deleteByIds(Integer[] ids) {
this.getSession().createQuery(" DELETE " + this.clazz.getName() + " this WHERE this.id IN(:ids) ")//
.setParameterList("ids", ids)//
.executeUpdate();
}
