Titanium数据库SQLite的使用
????
在Titanium的Database sqllit的使用如下:
// this sets the background color of the master UIView (when there are no windows/tab groups on it)Titanium.UI.setBackgroundColor('#000');//创建相关的数据库//打开相关的数据库var db = Titanium.Database.open('mydb');// create tab groupvar tabGroup = Titanium.UI.createTabGroup();//删除表中的数据//db.execute('DELETE FROM DATABASETEST');//创建相关的表db.execute('CREATE TABLE IF NOT EXISTS DATABASETEST (userName TEXT, passwd TEXT)');//// create controls tab and root window//var win2 = Titanium.UI.createWindow({ title:'添加人员', backgroundColor:'#fff'});var tab2 = Titanium.UI.createTab({ icon:'KS_nav_ui.png', title:'添加人员', window:win2});var lblName = Titanium.UI.createLabel({ text:'用户名: ', color:"#000000", top : Ti.Platform.displayCaps.platformHeight/2-200, left: 10, height:60, width:100, textAlign:'right'});var txtName = Ti.UI.createTextField({ top:Ti.Platform.displayCaps.platformHeight/2-200, left: lblName.width, width:Ti.Platform.displayCaps.platformWidth-lblName.width-40, height:60});var lblPassword = Titanium.UI.createLabel({ text:' 密码: ', color:"#000000", top : Ti.Platform.displayCaps.platformHeight/2-110, left: 10, height:60, width:100, textAlign:'right'});var txtPassword = Ti.UI.createTextField({top : Ti.Platform.displayCaps.platformHeight/2-110, left : lblPassword.width, width : Ti.Platform.displayCaps.platformWidth-lblPassword.width-40, height : 60});var btnSubmit = Ti.UI.createButton({title : '添加',top: Ti.Platform.displayCaps.platformHeight/2-10,left:Ti.Platform.displayCaps.platformWidth/2-110,width : 100,height : 60});btnSubmit.addEventListener('click',function(e){var userName=txtName.value;var passwd=txtPassword.value;//入参的集合var personArray=[userName,passwd];//执行插入操作 db.execute('INSERT INTO DATABASETEST (userName, passwd ) VALUES (?, ?)', personArray); //db.execute("COMMIT"); //获取影响的行数 Titanium.API.info('JUST INSERTED, rowsAffected = ' + db.rowsAffected); //获取影响行数的rowid Titanium.API.info('JUST INSERTED, lastInsertRowId = ' + db.lastInsertRowId); //创建一个提示框 var a = Titanium.UI.createAlertDialog({title:'添加人员信息',message:"人员添加成功",buttonNames: ['确定'],});a.show();});win2.add(lblName);win2.add(txtName);win2.add(lblPassword);win2.add(txtPassword);win2.add(btnSubmit);//// create base UI tab and root window//var win1 = Titanium.UI.createWindow({ title:'人员信息展示', backgroundColor:'#fff'});var tab1 = Titanium.UI.createTab({ icon:'KS_nav_views.png', title:'人员信息展示', window:win1});var data = [];function addRow(idx,nametext,passwordText){data[idx].add(Ti.UI.createLabel({text:nametext,height:20,width:50,left:10,right:50,top:10,textAlign:'left',bottom:10}));data[idx].add(Ti.UI.createLabel({text:passwordText,height:20,width:50,left:60,right:50,top:10,textAlign:'center',bottom:10}));}var header = Ti.UI.createView({backgroundColor:'#999',height:'auto'});var headerLabel = Ti.UI.createLabel({font:{fontFamily:'Helvetica Neue',fontSize:18,fontWeight:'bold'},text:'用户名称',color:'#222',height:20,width:50,left:10,right:50,top:10,textAlign:'left',bottom:10});var headerLabel2 = Ti.UI.createLabel({font:{fontFamily:'Helvetica Neue',fontSize:18,fontWeight:'bold'},text:'电子邮件',color:'#222',height:20,width:50,left:60,right:50,top:10,textAlign:'center',bottom:10});header.add(headerLabel);header.add(headerLabel2);// create table viewvar tableview = Titanium.UI.createTableView({data:data,minRowHeight:80,headerView:header,});// create table view event listenertableview.addEventListener('click', function(e){// event datavar index = e.index;var section = e.section;var row = e.row;var rowdata = e.rowData;var msg = 'row ' + row + ' index ' + index + ' section ' + section + ' row data ' + rowdata;Titanium.UI.createAlertDialog({title:'记录信息',message:msg}).show();});win1.add(tableview);tab1.addEventListener('click',function(){//查询数据库的表的记录var rows = db.execute('SELECT * FROM DATABASETEST'); //获取中的记录数Titanium.API.info('ROW COUNT = ' + rows.getRowCount());var index=0;while (rows.isValidRow()){data[index] = Ti.UI.createTableViewRow({hasDetail:true,height:'auto'});//获取数据集中记录的方式类似java jdbc//1.根据下表获取//2.根据列的名称获取addRow(index,rows.field(0),rows.fieldByName('passwd')); Titanium.API.info('ID: ' + rows.field(0) + ' passwd: ' + rows.fieldByName('passwd') + ' COLUMN NAME ' + rows.fieldName(0));rows.next();index++;}tableview.setData(data);//关闭数据集rows.close();//db.close(); // close db when you're done to save resources});//// add tabs//tabGroup.addTab(tab2); tabGroup.addTab(tab1); // open tab grouptabGroup.open();??
