Extjs中layout的用法总结
好久没看过EXT了,最近项目中需要用到就重新复习了下,对于一些知识也都模糊不清,现对Extjs中的layout布局进行总结下:
layout中有absolute,anchor,border,accordion,card,form,table,column,fit这几种,现一一举例:
1.absolute根据字面意思就知道,是根据具体坐标进行定位的,固不写相应的代码了,其他的如下
2.anchor:其值可以使百分比和数值,数值一般为负数,其代表的意思是如果宽度和长度中有一个设定值了,则anchor代表的是未设置的那个,如果两者都没有设定具体值,则如果需要使用anchor则需要anchro:'ww,hh'
Ext.onReady(function() { Ext.create('Ext.Window',{title:'Anchor layout',width:400,height:400,layout:'anchor',plain: true,items:[Ext.create('Ext.panel.Panel',{title:'panel1',height:100,anchor:'-50',html:'高度等于100,宽度= 容器宽度-50'}),Ext.create('Ext.panel.Panel',{title:'panel2',height:100,anchor:'50%',html:'高度等于100,宽度=容器的宽度*50%'}),Ext.create('Ext.panel.Panel',{title:'panel3',anchor:'-10,-200',html:'高度等于容器高度-10,宽度等于容器宽度-200'})]}).show(); }); Ext.onReady(function(){ var tab = Ext.create('Ext.tab.Panel',{region:'center',//border布局,将页面分成东,南,西,北,中五部分,这里表示TabPanel放在中间 margins:'3,3,3,0',activeTab:0,defaults:{autoScroll:true},items:[{title:'tab1',html:'第一个tab内容'},{title:'tab2',html:'第二个tab内容'},{title:'tab3',html:'第三个tab内容'}]})var nav = Ext.create('Ext.panel.Panel',{title:'navigation',region:'west',split:true,width:200,collapsible:true,//允许伸缩margins:'3,0,3,3',cmargins:'3,3,3,'});Ext.create('Ext.Window',{title:'Layout Window',width:600,height:350,closable:true,border:false,plain:true,layout:'border',closeAction:'hide',items:[nav,tab]}).show();)};Ext.OnReady(function(){ Ext.create('Ext.panel.Panel',{title:'容器组件',layout:'accordion',width:600,height:200,layoutConfig:{animate:false},items:[{ title:'元素1',html:''},{ title:'元素2',html:''},{ title:'元素3',html:''},{ title:'元素4',html:''}]}); }); Ext.onReady(function(){var navigate = function(panel,direction){var layout = panel.getLayout();layout[direction]();Ext.getCmp('move-prev').setDisabled(!layout.getPrev());Ext.getCmp('move-next').setDisabled(!layout.getNext());};Ext.create('Ext.panel.Panel',{title:'Example Wizard',height:500,width:400,layout: 'card',activeItem:0,bodyStyle:'padding:15px',animCollapse:true,renderTo:Ext.getBody(),defaults:{ // applied to each contained panel border: false },bbar:[{id:'move-prev',text:'back',handler:function(btn){navigate(btn.up("panel"),"prev");},disabled:true},'->',{id:'move-next',text:"next",handler:function(btn){navigate(btn.up("panel"),"next");}}],items:[{id:'card-0',html:'<h1>Welcome to the Wizard!</h1>'},{id:'card-1',html:'<p>step 2 of 3 </p>'},{id:'card-2',html:'<h1>Congratulations!</h1><p>Step 3 of 3-complete</p>'}]});});Ext.onReady(function() { var win = Ext.create('Ext.Window',{ title: "form Layout", height: 150, width: 230, plain: true, bodyStyle: 'padding:15px', items: { xtype: "form", labelWidth: 30, defaultType: "textfield", frame:true, items: [ { fieldLabel:"姓名", name:"username", allowBlank:false }, { fieldLabel:"呢称", name:"nickname" }, { fieldLabel: "生日", xtype:'datefield', name: "birthday", width:127 } ] } }); win.show(); }); Ext.onReady(function(){ Ext.create('Ext.panel.Panel', { renderTo:Ext.getBody(), title:'容器组件', layout:'table', width:500, height:200, layoutConfig:{columns:3},//将父容器分成3列 items:[ {title:'元素1',html:'ssssssssss',rowspan:2,height:100}, {title:'元素2',html:'dfffsddsdfsdf',colspan:2}, {title:'元素3',html:'sdfsdfsdf'}, {title:'元素4',html:''} ] } ); }); Ext.onReady(function() { var win = Ext.create('Ext.Window',{ title: "Column Layout", height: 300, width: 400, plain: true, layout: 'column', items: [{ title:"width=50%", columnWidth:0.5, html:"width=(容器宽度-容器内其它组件固定宽度)*50%", height:200 }, { title:"width=250px", width: 200, height:100, html:"固定宽度为250px" } ] }); win.show(); }); Ext.OnReady(function(){ Ext.create(Ext.create(Ext.panel.Panel', { renderTo:'paneldiv', title:'容器组件', layout:'fit', width:500, height:100, items:[ {title:'子元素1'}, {title:'子元素2'}, {title:'子元素3'}, {title:'子元素4'}, {title:'子元素5'} ] } ); });
