JQuery EasyUi之界面设计——通用的JavaScript
所谓磨刀不误砍柴工，先写点通用的代码，后面开发起来效率就高多了。多余的话就不敲了，先简单介绍介绍吧。
时间格式化
对于序列化JSON，我喜欢用JSON.NET，为了方便，我定义了一个扩展方法，如下面代码：
1: /// <summary>
2: /// 将对象序列化为JSON数据
3: /// </summary>
4: /// <param name="instance"></param>
5: /// <returns></returns>
6: public static string ToJson(this object instance)
7: {
8: return JsonConvert.SerializeObject(instance);
9: }
那么序列化JOSN输出那么就方便多了，如下面代码：
1: var info = from a in db.TB_KTVAndConcert
2: join b in db.TB_City on a.Cityid equals b.ID
3: where a.AttributeCode == "AttrubuteCode".GetRequest()
4: orderby a.Cityid
5: select new
6: {
7: a.CreateDate,
8: a.Defaultflag,
9: a.ID,
10: a.Name,
11: a.Cityid,
12: b.CityName,
13: a.Displayindex
14: };
15: if ("CityID".GetRequest().IsNotEmpty())
16: {
17: if (MyRegex.IsNumberRegex("CityID".GetRequest()))
18: {
19: int cityId = Convert.ToInt32("CityID".GetRequest());
20: info = info.Where(p => p.Cityid == cityId);
21: }
22: }
23: context.Response.Write(info.OrderByDescending(p => p.Defaultflag).ThenBy(p => p.Displayindex).ToJson());
序列化JSON是可以了，但是前台显示DateTime类型数据时显示就有问题了，也就是获取不到想要的格式化字符串。解决这个问题有两种方式，方式一就是定义一个C#方法来返回格式化时间字符串，关键部分代码如下：
1: select new
2: {
3: CreateDate = a.CreateDate.GetDateTimeString(),
4: a.Defaultflag,
5: a.ID,
6: a.Name,
7: a.Cityid,
8: b.CityName,
9: a.Displayindex
10: };
这样虽然可以，但是如果我想统一在浏览器端处理呢？于是封装下面的函数：
1: //时间格式化
2: Date.prototype.format = function (format) {
3: if (!format) {
4: format = "yyyy-MM-dd hh:mm:ss";
5: }
6: var o = {
7: "M+": this.getMonth() + 1, // month
8: "d+": this.getDate(), // day
9: "h+": this.getHours(), // hour
10: "m+": this.getMinutes(), // minute
11: "s+": this.getSeconds(), // second
12: "q+": Math.floor((this.getMonth() + 3) / 3), // quarter
13: "S": this.getMilliseconds()
14: // millisecond
15: };
16: if (/(y+)/.test(format)) {
17: format = format.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
18: }
19: for (var k in o) {
20: if (new RegExp("(" + k + ")").test(format)) {
21: format = format.replace(RegExp.$1, RegExp.$1.length == 1 ? o[k] : ("00" + o[k]).substr(("" + o[k]).length));
22: }
23: }
24: return format;
25: };
26: function fomatDate(str) {
27: return (new Date(parseInt(str.substring(str.indexOf('(') + 1, str.indexOf(')'))))).format("yyyy-MM-dd hh:mm:ss");
28: }
前台调用：
1: function formatCreateDate(value, row, index) {
2:
3: return fomatDate(row.CreateDate);
4:
5: }
显示效果：
消息框
弹出框以及系统消息框
1: function showMsg(title, msg, isAlert) {
2: if (isAlert !== undefined && isAlert) {
3: $.messager.alert(title, msg);
4: } else {
5: $.messager.show({
6: title: title,
7: msg: msg,
8: showType: 'show'
9: });
10: }
11: }
确认框
1: function showConfirm(title, msg, callback) {
2: $.messager.confirm(title, msg, function (r) {
3: if (r) {
4: if (jQuery.isFunction(callback))
5: callback.call();
6: }
7: });
8: }
进度框
1: function showProcess(isShow, title, msg) {
2: if (!isShow) {
3: $.messager.progress('close');
4: return;
5: }
6: var win = $.messager.progress({
7: title: title,
8: msg: msg
9: });
10: }
例如在表单提交时，为了防止重复提交，会显示一个进度框。提交完成时，关闭进度框并提示操作信息：
1: function submitForm(url) {
2: $('#ff').form('submit', {
3: url: (url === undefined ? "/Ajax/Common.ashx" : url) + "?Type=" + typeCode,
4: onSubmit: function () {
5: var flag = $(this).form('validate');
6: if (flag) {
7: showProcess(true, '温馨提示', '正在提交数据...');
8: }
9: return flag
10: },
11: success: function (data) {
12: showProcess(false);
13: if (data == 1) {
14: top.showMsg('温馨提示', '提交成功！');
15: if (parent !== undefined) {
16: if ($.isFunction(window.reloadParent)) {
17: reloadParent.call();
18: } else {
19: parent.$("#tt").datagrid('reload');
20: parent.closeMyWindow();
21: }
22: }
23: } else {
24: $.messager.alert('温馨提示', data);
25: }
26: },
27: onLoadError: function () {
28: showProcess(false);
29: $.messager.alert('温馨提示', '由于网络或服务器太忙，提交失败，请重试！');
30: }
31: });
32: }
关键页面代码如下：
1: <div class="easyui-layout" style="text-align: left; height: 270px;" fit="true">
2:
3: <div region="center" border="false" style="padding: 10px; background: #fff; border: 1px solid #ccc;">
4:
5: <form id="ff" method="post">

136:
137: </div>
138:
139: <script type="text/javascript">
140:
141: $(function () {
142:
143: if (autoLoad == 1) {
144:
145: $('#txtPassword').keypress(function () {
146:
147: if ($(this).val().length > 0) {
148:
149: $('#txtPassword2').validatebox({

159: if ($(this).val().length > 0) {
160:
161: $('#txtPassword2').validatebox({
162:
163: required: true
164:
165: });
166:
167: } else {
168:
169: $('#txtPassword2').validatebox({
170:
171: required: false
172:
173: });
174:
175: }
176:
177: });
178:
179:
180:
181: } else {
182:
183: $('#txtPassword,#txtPassword2').validatebox({
184:
185: required: true
186:
187: }); ;
188:
189: }
190:
191: });
192:
193: </script>
194:
效果如下：
窗口
窗口是用的非常频繁的，显示窗口：
1: $(function () {
2: $('body').append('<div id="myWindow" class="easyui-dialog" closed="true"></div>');
3: });
4: function showMyWindow(title, href, width, height, modal, minimizable, maximizable) {
5: $('#myWindow').window({
6: title: title,
7: width: width === undefined ? 600 : width,
8: height: height === undefined ? 400 : height,
9: content: '<iframe scrolling="yes" frameborder="0" src="' + href + '" style="width:100%;height:98%;"></iframe>',
10: // href: href === undefined ? null : href,
11: modal: modal === undefined ? true : modal,
12: minimizable: minimizable === undefined ? false : minimizable,
13: maximizable: maximizable === undefined ? false : maximizable,
14: shadow: false,
15: cache: false,
16: closed: false,
17: collapsible: false,
18: resizable: false,
19: loadingMessage: '正在加载数据，请稍等片刻......'
20: });
21: }
关闭窗口：
1: function closeMyWindow() {
2: $('#myWindow').window('close');
3: }
使用方式如下：
1: function onDataGridDblClickRow(rowIndex, rowData) {
2:
3: edit();
4:
5: }
6:
7: function addType() {
8:
9: showMyWindow('用户管理 | 新建', '/WebPages/RoleManagement/AdminUser_Add.aspx', 600, 320)
10:
11: }
12:
13: function edit() {
14:
15: var row = $('#tt').datagrid('getSelected');
16:
17: if (row) {
18:
19: showMyWindow('用户管理 | 编辑', '/WebPages/RoleManagement/AdminUser_Add.aspx?ID=' + row.ID + '&autoLoad=1', 600, 320)
20:
21: } else {
22:
23: showMsg("温馨提示", "请选择一行！");
24:
25: }
26:
27: }
窗口弹出有本页弹出，有时由于框架页太小，经常会使用顶层窗口弹出，如：
1: function showSetPicWindow(adname, id) {
2:
3: top.showMyWindow(adname + " | 广告图设置", '/WebPages/ADManagement/ADPicturesManagement.aspx?TypeCode=ADPictures&ID=' + id + '&ATCode=KTVAdvert', 707, 440);
4:
5: }
效果如下：
表单
一个系统总是不乏表单的，自然表单的提交与赋值自然是频繁的。如果使用C#，可以通过反射减少工作量，但是我更趋向把工作量留给前台。比如提交：
1: function submitForm(url) {
2: $('#ff').form('submit', {
3: url: (url === undefined ? "/Ajax/Common.ashx" : url) + "?Type=" + typeCode,
4: onSubmit: function () {
5: var flag = $(this).form('validate');
6: if (flag) {
7: showProcess(true, '温馨提示', '正在提交数据...');
8: }
9: return flag
10: },
11: success: function (data) {
12: showProcess(false);
13: if (data == 1) {
14: top.showMsg('温馨提示', '提交成功！');
15: if (parent !== undefined) {
16: if ($.isFunction(window.reloadParent)) {
17: reloadParent.call();
18: } else {
19: parent.$("#tt").datagrid('reload');
20: parent.closeMyWindow();
21: }
22: }
23: } else {
24: $.messager.alert('温馨提示', data);
25: }
26: },
27: onLoadError: function () {
28: showProcess(false);
29: $.messager.alert('温馨提示', '由于网络或服务器太忙，提交失败，请重试！');
30: }
31: });
32: }
值得说明的是：
- typeCode来自母版页，为页面名。
- url为提交的URL。
- onSubmit事件会触发表单验证，如果验证通过会显示提交进度遮罩层。如果觉得不够用，可以自己扩展。
- success事件会关闭进度，如果提交成功会显示成功提示，如果存在父窗口，会刷新父页面DataGrid并且关闭当前窗口。当然也可以实现reloadParent函数来个性化处理。
- 表单id和DataGrid的id都是固定的，如果没有效果请检查id。
- 关于表单的这里只写了提交，赋值的代码写在母版页了，以后再说。
页面html的提交代码如下：
1: <a class="easyui-linkbutton" iconcls="icon-save" href="javascript:void(0)" onclick="javascript:submitForm('/Ajax/ShortMMS_Common.ashx');">
2: 提交</a>
有些页面可能刷新DataGrid还不够，需要刷新页面，于是可以使用下面的JS：
1: <script type="text/javascript">
2: function reloadParent() {
3: top.showProcess(false);
4: parent.showMsg('温馨提示', '提交成功');
5: parent.document.location.reload();
6: }
7: </script>
最后，附上完整的JS代码：
1: //时间格式化
2: Date.prototype.format = function (format) {
3: if (!format) {
4: format = "yyyy-MM-dd hh:mm:ss";

11: "s+": this.getSeconds(), // second
12: "q+": Math.floor((this.getMonth() + 3) / 3), // quarter
13: "S": this.getMilliseconds()
14: // millisecond
15: };
16: if (/(y+)/.test(format)) {
17: format = format.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));

22: }
23: }
