Ext.js入门:Window对象与FormPanel(六)
Windows既可关联到Ext.WindowGroup或籍由Ext.WindowManager来管理, 提供分组(grouping),活动(activation),置前/置后(to front/back)或其它应用程序特定的功能。
缺省状态下,窗体都渲染到document.body。要强制constrain窗体以某个元素为依托就要使用renderTo方法。
<div id="win" class="x-hidden"></div>
var w=new Ext.Window({
el:"win",//主体显示的html元素
width:300,
height:200,
title:"标题"
});
w.show();
3.参数介绍:
1.closeAction:枚举值为:
close(默认值),当点击关闭后,关闭window窗口
hide,关闭后,只是hidden窗口
2.closable:true在右上角显示小叉叉的关闭按钮,默认为true
3.constrain:true则强制此window控制在viewport,默认为false
4.modal:true为模式窗口,后面的内容都不能操作,默认为false
5.plain://true则主体背景透明,false则主体有小差别的背景色,默认为false
w.show()
contentEl:"win",
width:300,
height:200,
items:new Ext.TabPanel({
activeTab:0,//当前标签为第1个tab(从0开始索引) 设置选项卡的激活状态
border:false,
items:[{title:"tab1",html:"tab1在windows窗口中"},{title:"tab2",html:"tab2在windows窗口中"}]//TabPanel中的标签页,以后再深入讨论
}),
plain:true,//true则主体背景透明,false则主体有小差别的背景色,默认为false
title:"标题"
});
w.show();
buttons:[{text:“确定”},{text:“取消”,handler:function(){w.close();}}],//footer部
buttonAlign:“center”,//footer部按钮排列位置,这里是中间
// collapsible:true,//右上角的收缩按钮
其他与Panel一样!
Ext.form.FormPanel = Ext.FormPanel;
<body>
<div id="form1"></div>
</body>
var form1 = new Ext.form.FormPanel({
width:350,
frame:true,//圆角和浅蓝色背景
renderTo:"form1",//呈现
title:"FormPanel",
bodyStyle:"padding:5px 5px 0", //边距
fieldLabel:"UserName",//文本框标题
// xtype:"textfield",//表单文本框
name:"user",
id:"user",
// width:200
},
fieldLabel:"PassWord",
// xtype:"textfield",
name:"pass",
id:"pass",
// width:200
}
],
buttons:[{text:"确定"},{text:"取消",handler:function(){alert("事件!");}}]
});
check
text(默认)
file
password等等
2.labelWidth:fieldlabel的占位宽
3.method:"get"或"post"
4.url:"提交的地址"
5.submit:提交函数
<head runat="server"> <title></title> <link href="Ext/resources/css/ext-all.css" rel="stylesheet" type="text/css" /> <script src="Ext/adapter/ext/ext-base.js" type="text/javascript"></script> <script src="Ext/ext-all.js" type="text/javascript"></script> <script src="Ext/ext-lang-zh_CN.js" type="text/javascript"></script> <script type="text/javascript"> Ext.onReady(function() { var frmLogin = new Ext.form.FormPanel({ title: "登录", width: 350, frame: true, bodyStyle:"padding:10px 10px 0 0", renderTo: "contaner", items:[{ xtype:"fieldset", title: '个人信息', collapsible: true, autoHeight:true, width:330, defaults: { width: 150 }, defaultType: "textfield", items:[ { fieldLabel: '爱好', name: 'hobby', value: '上网、打游戏' }, { xtype:"combo", name:"sex", store:["男","女","保密"], fieldLabel:"性别", emptyText:"请选择性别" } ] }], buttonAlign:"center", buttons: [{ text: "登录" }, { text: "退出", handler: function() { frmLogin.hide(); } }] }); }); </script> </head> <body> <div id="contaner"></div> </body> </html>

<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <link href="Ext/resources/css/ext-all.css" rel="stylesheet" type="text/css" /> <script src="Ext/adapter/ext/ext-base.js" type="text/javascript"></script> <script src="Ext/ext-all.js" type="text/javascript"></script> <script src="Ext/ext-lang-zh_CN.js" type="text/javascript"></script> <script type="text/javascript"> Ext.onReady(function() { Ext.QuickTips.init(); //支持tips提示 Ext.form.Field.prototype.msgTarget = 'side'; //提示的方式 Ext.apply(Ext.form.VTypes, { password: function(val, field) { if (field.confirmTo) { var pwd = Ext.get(field.confirmTo); return (val == pwd.getValue()); } return true; } }); var frmLogin = new Ext.form.FormPanel({ title: "登录", width: 350, frame: true, bodyStyle: "padding:10px 10px 0 0", renderTo: "contaner", items: [{ xtype: "fieldset", title: '个人信息', collapsible: true, autoHeight: true, width: 330, defaults: { width: 150 }, defaultType: "textfield", items: [ { fieldLabel: '爱好', name: 'hobby', value: '上网、打游戏' }, { xtype: "combo", name: "sex", store: ["男", "女", "保密"], fieldLabel: "性别", emptyText: "请选择性别" } ] }, { xtype: "fieldset", checkboxToggle: true, //有checkbox的选择框 checkboxName: "chkinfo",
autoHeight:true,//使自适应展开排版 title: "选填信息", defaultType: "textfield", width: 330, autoHeight: true, items: [ { fieldLabel: "UserName", name: "user", anchor: "95%", vtype: "email", //email格式验证 vtypeText: "不是有效的邮箱地址" }, { fieldLabel: "PassWord", name: "pass", id: "pass", inputType: "password", anchor: "95%", //对应整个的宽度 剩下的宽度的95%,留下5%作为后面提到的验证错误提示 allowBlank: false, blankText: "密码不允许为空!" }, { fieldLabel: "ConfirmPass", id: "confirmpass", name: "confirmpass", vtype: "password", vtypeText: "两次密码输入不一致!", confirmTo: "pass", inputType:"password", anchor: "95%" } ] }], buttonAlign: "center", buttons: [{ text: "登录" }, { text: "退出", handler: function() { frmLogin.hide(); } }] }); }); </script> </head> <body> <div id="contaner"></div> </body> </html>
我们可以用单独的js写表单验证,但是extjs已经为我们想到了(自己单独写反而不方便)。
在验证之前,我不得不提两个小知识点:
//大家在很多的extjs代码中都看到了这两个,他们都起提示作用的
Ext.QuickTips.init();//支持tips提示
Ext.form.Field.prototype.msgTarget='side';//提示的方式,枚举值为"qtip","title","under","side",id(元素id)
//side方式用的较多,右边出现红色感叹号,鼠标上去出现错误提示,其他的我就不介绍了,可自行验证
//大家可以分别去掉这两行代码,看效果就会明白他们的作用,(放在onReady的function(){}中)
1.allowBlank:false//false则不能为空,默认为true
2.blankText:string//当为空时的错误提示信息
var form1 = new Ext.form.FormPanel({ width:350, frame:true, renderTo:"form1", labelWidth:80, title:"FormPanel",
4.2用vtype格式进行简单的验证。
items:[ {fieldLabel:"不能为空", vtype:"email",//email格式验证 vtypeText:"不是有效的邮箱地址",//错误提示信息,默认值我就不说了 id:"blanktest", anchor:"90%" }
//form验证中vtype的默认支持类型
1.alpha //只能输入字母,无法输入其他(如数字,特殊符号等)
2.alphanum//只能输入字母和数字,无法输入其他
3.email//email验证,要求的格式是“langsin@gmail.com”
4.url//url格式验证,要求的格式类似于
Ext.apply(Ext.form.VTypes,{ password:function(val,field){//val指这里的文本框值,field指这个文本框组件,大家要明白这个意思 if(field.confirmTo){//confirmTo是我们自定义的配置参数,一般用来保存另外的组件的id值 var pwd=Ext.get(field.confirmTo);//取得confirmTo的那个id的值 return (val==pwd.getValue()); } return true; } });
5.Checkbox 和Radio简单示例
<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <link href="Ext/resources/css/ext-all.css" rel="stylesheet" type="text/css" /> <script src="Ext/adapter/ext/ext-base.js" type="text/javascript"></script> <script src="Ext/ext-all.js" type="text/javascript"></script> <script src="Ext/ext-lang-zh_CN.js" type="text/javascript"></script> <script type="text/javascript"> Ext.onReady(function() { var myform = new Ext.FormPanel({ frame: true, width: 500, layout: "form", labelWidth: 30, title: "checkBox示例", labelAlign: "left", renderTo: Ext.getBody(), items: [{ xtype: "panel", layout: "column", fieldLabel: "爱好", items: [ { columnWidth:.2, xtype:"checkbox", boxLabel:"足球" }, { columnWidth: .2, xtype: "checkbox", boxLabel: "篮球" } ] }, { xtype: "panel", layout: "column", fieldLabel: "性别", items: [ { columnWidth:.2, xtype:"radio", boxLabel:"男", name:"sex" }, { columnWidth: .2, xtype: "radio", boxLabel: "女", name:"sex" } ] }, { xtype: "panel", layout: "form", labelWidth: 50, height: 100, labelAlign:"top", items: [ { xtype:"htmleditor", fieldLabel:"备注", anchor:"99%" } ] } ] } ); }) </script> </head> <body> <form id="form1" runat="server"> <div> </div> </form> </body> </html>
1.checked:true//true则选中,默认为false
2.name:"**"//name值
3.value:""//初始化值,默认为undefine
6.htmleditor简单示例
Ext.onReady(function(){
Ext.QuickTips.init();
var myform=new Ext.FormPanel({
frame:true,
width:600,
layout:"form",
labelWidth:50,
title:"htmleditor简单示例",
labelAlign:"top",//items中的标签的位置
renderTo:Ext.getBody(),
items:[{
xtype:"htmleditor",
id:"he",
fieldLabel:"编辑器",
anchor:"99%"
}]
);
labelAlign:此参数是指form表单中items各项的label位置,默认值为left,枚举值有left,right,top
1.hideLabel:true//默认为false,还适用于有标签的所有表单组件
//下面的一组参数控制编辑器的工具栏选项,都是默认值为true
2.enableColors:true//默认为true,显示字体颜色,字体背景颜色
3.enableAlignments:true//左,中,右对齐
4.enableFont:true//字体
5.enableFontSize:false//字体大小,就是A旁边有个小箭头的
6.enableFormat:false//粗体,斜体,下划线
7.enableLinks:true//链接
8.enableLists:true//列表
9.enableSourceEdit:true//源代码编辑
