EXTJS Ext.Window Scroll
windowTerms = new Ext.Window({ autoWidth: true,autoHeight: true,header: false,closable: false,modal: false,autoScroll: true,frame: false,border: false,html: html }); windowTerms.show(); } function window_termspopClose() { windowTerms.hide(); }
解决方法
Ext4.2的Ext.grid.plugin.RowExpander无法触发事件解决办法_extjs
ext4.2+ ext.grid.plugin.rowexpander存在bug,添加的collapsebody,expandbody无法触发,查看了下 ext.grid.plugin.rowexpander对应的源代码,没有添加collapsebody,expandbody事件,即使按照网上的方 法重写ext.grid.plugin.rowexpander的init和togglerow方法也无法触发 collapsebody,expandbody事件。
解决办法:给grid对象添加collapsebody,expandbody事件,然后给grid配置这2个事件,同时重写Ext.grid.plugin.RowExpander的toggleRow方法,触发grid添加的这2个事件即可。
测试源代码如下:

''removeCls'' : ''addCls'', ownerLock, rowHeight, fireView; // Suspend layouts because of possible TWO views having their height change Ext.suspendLayouts(); row[addOrRemoveCls](me.rowCollapsedCls); Ext.fly(nextBd)[addOrRemoveCls](me.rowBodyHiddenCls); me.recordsExpanded[record.internalId] = isCollapsed; view.refreshSize(); // Sync the height and class of the row on the locked side if (me.grid.ownerLockable) { ownerLock = me.grid.ownerLockable; // fireView = ownerLock.getView(); view = ownerLock.lockedGrid.view; fireView=ownerLock.lockedGrid.view; rowHeight = row.getHeight(); // EXTJSIV-9848: in Firefox the offsetHeight of a row may not match // it is actual rendered height due to sub-pixel rounding errors. To ensure // the rows heights on both sides of the grid are the same, we have to set // them both. row.setHeight(isCollapsed ? rowHeight : ''''); row = Ext.fly(view.getNode(rowIdx), ''_rowExpander''); row.setHeight(isCollapsed ? rowHeight : ''''); row[addOrRemoveCls](me.rowCollapsedCls); view.refreshSize(); } else { fireView = view; } //通过grid触发事件,而不是view this.grid.fireEvent(isCollapsed ?

EXTJS - 在 window 组件中绑定事件
[在 jsp 中用 EXTJS 绑定事件]
Ext.onReady(function(){
//ex001:点击一个按钮 ,打开一个新的窗体 window重复创建的问题
//第一种实现【推荐】
//JQuery code: var btn = $(''#btn''); var dombtn = btn.get(0);
// alert(btn.dom.value) 取到 原生的dom对象value值
var btn = Ext.get(''btn''); //这个元素是经过Ext包装的一个Ext的Dom对象//alert(btn.dom.value);
btn.on(''click'',function(){ //绑定一个事件click, 用on绑定事件。
if(!Ext.getCmp(''mywin'')){ //判断是否有组件 mywin
Ext.create(''Ext.window.Window'',{
id:''mywin'' , //如果你给组件加了一个id 那么这个组件就会被Ext所管理
title:''新窗体'' ,
height:300 ,
width:400 ,
renderTo:Ext.getBody() //,
//modal:true //模态窗口,解决widow重复创建窗口的问题。
}).show();
}
});
//第二种实现 [不推荐]
// var win = Ext.create(''Ext.window.Window'',{
// title:''新窗体'' ,
// height:300 ,
// width:400 ,
// renderTo:Ext.getBody() ,
// closeAction:''hide'' //closeAction默认是destroy
// });
//
// Ext.get(''btn'').on(''click'',function(){
// win.show();
// });
});
ExtJS 2.0实用简明教程 之ExtJS版的Hello_extjs
<script> <BR>Ext.onReady(function() <BR>{ <BR>Ext.MessageBox.alert("hello","Hello,easyjf open source"); <BR>}); <BR></script>

进一步,我们可以在页面上显示一个窗口,代码如下:
<script> <BR>Ext.onReady(function() <BR>{ <BR>var win=new Ext.Window({title:"hello",width:300,height:200,html:''<h1>Hello,easyjf open source''}); <BR>win.show(); <BR>}); <BR></script>
