首先必须知道例外两个方法 Ext.MessageBox.hide()和Ext.MessageBox.updateProgress(value,"ProgressText","msg")(三个参数，看名字就知道意思)，
注意value为0-1之间的数，表示进度条的进度.
第一种：（通过进度的大小控制进度，满进度为1）
代码
| 代码如下 | 复制代码 |
| function Read4() { var progressBar=Ext.Msg.show({ title:"标题", msg:"通过进度的大小来控制进度", progress:true, width:300 }); var count=0; var bartext=""; var curnum=0; Ext.TaskMgr.start({ run:function () { count++; if (count>=10) { progressBar.hide(); } curnum=count/10; bartext=curnum*100+"%"; progressBar.updateProgress(curnum,bartext); }, interval:1000 }) } |
|
第二种：（通过固定时间控制进度加载）
代码
代码
| 代码如下 | 复制代码 |
| function Read5() { var progressBar=Ext.Msg.show({ title:"标题", msg:"通过固定时间完成进度", width:300, wait:true, waitConfig:{interval:500,duration:5000,fn:function () { Ext.Msg.hide(); }}, closable:true }); // setTimeout(function () { // Ext.Msg.hide(); // },5000); } |

动态更新进度信息
上面看上去很好但在实例应用中我发现,等待进度条(Wait mask)灰色蒙版不能正常隐藏的BUG，下面我修改了一下实例
| 代码如下 | 复制代码 |
|
Ext.define('Ext.form.SubmitFix', { override: 'Ext.ZIndexManager', register : function(comp) { var me = this, compAfterHide = comp.afterHide; if (comp.zIndexManager) { comp.zIndexManager.unregister(comp); } comp.zIndexManager = me; me.list[comp.id] = comp; me.zIndexStack.push(comp); // Hook into Component's afterHide processing comp.afterHide = function() { compAfterHide.apply(comp, arguments); me.onComponentHide(comp); }; }, /** * Unregisters a {@link Ext.Component} from this ZIndexManager. This should not * need to be called. Components are automatically unregistered upon destruction. * See {@link #register}. * @param {Ext.Component} comp The Component to unregister. */ unregister : function(comp) { var me = this, list = me.list; delete comp.zIndexManager; if (list && list[comp.id]) { delete list[comp.id]; // Relinquish control of Component's afterHide processing delete comp.afterHide; Ext.Array.remove(me.zIndexStack, comp); // Destruction requires that the topmost visible floater be activated. Same as hiding. me._activateLast(); } } }); |

该BUG会在4.1.2版本中修正，提前修正的方法为将下面的补丁代码加入项目中:
