创建com对象并设置其字段

1、创建com对象并设置其字段示例： (new App) .create(/ function (com) /被成功创建的对象com linb.Ajax("ListLinksql.ashx", null, function (rsp) var obj = _.unserialize(rsp); for (i = 0; i < obj.records.length; i+) var rec = obj.recordsi; var items = obj.records; itemsi.id = rec.id; itemsi.caption = ; com.l

2、ist1.setItems(items); com.list1.setValue(items0.caption); , function (msg) linb.log(msg); ).start(); ).show();/显示ins:ins.show();示例：linb.SC('App', function () var com = new this; com.create(function (com) linb.Ajax("ListLinksql.ashx", null, function (rsp) var obj = _.unserialize(rsp

3、);ngth; i+) var rec = obj.recordsi; var items = obj.records; itemsi.id = rec.id; itemsi.caption = ; com.list1.setItems(items); com.list1.setValue(items0.caption); ).start(); /linb.Ajax , false).show(); /com.create);/linb.SCselectLink.htm: / 默认的代码是一个从 linb.Com 派生来的的类 Class('App', '

4、;linb.Com', / 要确保键值对的值不能包含外部引用 Instance: list1: null, list2: null, / 实例的属性要在此函数中初始化，不要直接放在Instance下 initialize: function () / 本Com是否随着第一个控件的销毁而销毁 this.autoDestroy = true; / 初始化属性 perties = ; , / 初始化内部控件（通过界面编辑器生成的代码，大部分是界面控件） / * 如果您不是非常熟悉linb框架，请慎重手工改变本函数的代码 * iniComponents: function ()

5、 / code created by jsLinb UI Builder var host = this, children = , append = function (child) children.push(child.get(0) ; append( (this.list1 = new linb.UI.ComboInput) .setHost(host, "ctl_comboinput2") .setLeft(10) .setTop(30) .setWidth(280) .afterUIValueSet("_ctl_comboinput2_afteruiv

6、alueset") ); append( (this.list2 = new linb.UI.ComboInput) .setHost(host, "ctl_comboinput3") .setLeft(300) .setTop(30) .setWidth(280) /.setItems(items2) ); append( (new linb.UI.SLabel) .setHost(host, "ctl_slabel1") .setLeft(10) .setTop(10) .setWidth(280) .setCaption("学院

7、") ); append( (new linb.UI.SLabel) .setHost(host, "ctl_slabel3") .setLeft(300) .setTop(10) .setWidth(280) .setCaption("部门") ); return children; / code created by jsLinb UI Builder , / 加载其他Com可以用本函数 iniExComs: function (com, threadid) , / 可以自定义哪些界面控件将会被加到父容器中 customAppend: fu

8、nction (parent, subId, left, top) / "return false" 表示默认情况下所有的第一层内部界面控件会被加入到父容器 return false; , / Com本身的事件映射 events: , _ctl_comboinput2_afteruivalueset: function (profile, oldValue, newValue) var ns = this, uictrl = profile.boxing(); var id; _.each(uictrl.getItems(), function (o) /由Value获得数

9、据项id if (o.caption = newValue) id = o.id; ); var ctl_comboinput3 = this.ctl_comboinput3; linb.Ajax("select.ashx", id: id , function (rsp) var obj = _.unserialize(rsp); var items = obj.records; /设置items2的空间大小 for (i = 0; i < obj.records.length; i+) /设置items2中的数据项集合 var rec = obj.recordsi

10、; itemsi.id = rec.id; itemsi.caption = ; ctl_comboinput3.setItems(items); ctl_comboinput3.setValue(items0.caption); , function (msg) linb.log(msg); ).start(); );/ (new App)/ .create(/ function (ins) /被成功创建的对象ins/ linb.Ajax("ListLinksql.ashx", null, function (rsp) / var obj = _.unse

11、rialize(rsp);/ for (i = 0; i < obj.records.length; i+) / var rec = obj.recordsi;/ var items = obj.records;/ itemsi.id = rec.id;/ itemsi.caption = ;/ / ins.list1.setItems(items);/ ins.list1.setValue(items0.caption); / ,/ function (msg) linb.log(msg); ).start();/ )/ .show();/显示ins:ins.show(

12、);/或linb.SC('App', function () var com = new this; com.create(function (com) linb.Ajax("ListLinksql.ashx", null, function (rsp) var obj = _.unserialize(rsp); for (i = 0; i < obj.records.length; i+) var rec = obj.recordsi; var items = obj.records; itemsi.id = rec.id; itemsi.capti

13、on = ; com.list1.setItems(items); com.list1.setValue(items0.caption); ).start(); /linb.Ajax , false).show(); /com.create);/linb.SC ListLinksql.ashx： public void ProcessRequest(HttpContext context) context.Response.ContentType = "text/plain" string date = "" date += "

14、 records: " string s = "" DbHelper db = new DbHelper("Data Source=.SQLEXPRESS;AttachDbFilename=|datadirectory|LIMS.mdf;Integrated Security=True;User Instance=True"); string select = "select collegeid,collegename from college" SqlDataReader dr = db.ExecuteReader(sel

15、ect); while (dr.Read() s += string.Format(" id: '0', name: '1',", dr"collegeid".ToString(), dr"collegename".ToString(); date = (date + s).TrimEnd(new char ',' ); date += "" context.Response.Write(date);Select1.ashx: public void ProcessR

16、equest(HttpContext context) context.Response.ContentType = "text/plain" string id=context.Request"id" string date = "" date += " records: " string s = "" DbHelper db = new DbHelper("Data Source=.SQLEXPRESS;AttachDbFilename=|datadirectory|LIMS.mdf;Integrated Security=True;User Instance=True"); string select = "select departmentid,departmentname from department where collegeid='"+id+"'" SqlDataReader dr = db.ExecuteReader(select); whi
