显示消息框ext窗口beforeclose事件 [英] show message box ext window beforeclose event

问题描述

当用户单击ext窗口的（X）按钮时，我想显示消息框，消息框窗口的ok按钮将关闭。我写代码，但它首先比显示消息框关闭窗口。这是代码：

I want to show message box when user click (X) button of ext window, and on 'ok' button of message box window will close. i write the code but it closes window first than show message box. Here is the code:

var assignReportFlag = 0;
var assignReportLoader = function(title,url){   
var panel = new Ext.FormPanel({
    id: 'arptLoader',
    height: 485,
    border: false,
    layout: 'fit',      
    autoScroll: true,
    method:'GET',
    waitMsg: 'Retrieving form data',
    waitTitle: 'Loading...',
    autoLoad: {url: url,scripts: true}
});

var cqok = new Ext.Button({
    text:'OK',
    id:'1',
    handler: function(){            
        if(assignReportFlag == 1){
            assignReportFlag = 0;
            Ext.MessageBox.alert('Status', 'Changes has been saved successfully',showResult);
        }else{
            assignReportWindow.close();         
        }           
    }
});

var assignReportWindow = new Ext.Window({       
    layout:'fit',
    title: title,       
    height:Ext.getBody().getViewSize().height - 60,
    width:Ext.getBody().getViewSize().width-20,
    closable: true,
    modal:true,
    resizable: false,
    autoScroll:true,
    plain: true,
    border: false,
    items: [panel],
    buttons: [cqok],
    listeners:{
        beforeclose:function(){
            if(assignReportFlag == 1){
                assignReportFlag = 0;
                Ext.MessageBox.alert('Status', 'Changes has been saved successfully',showResult);
            }else{
                assignReportWindow.destroy();           
            }
        }
    }
});

function showResult(btn){       
    assignReportWindow.destroy();   
};

assignReportWindow.show();
};

推荐答案

在您的 beforeclose 监听器返回false以停止关闭事件被触发。

In your beforeclose listener return false to stop the close event being fired.
