Question

我想在打开其他窗口之前关闭窗口，我试图按照下面的方式做但不起作用，是否有人可以帮助我？

我的代码片段：

listeners: {
    click: function() {
        var win = new Ext.window.Window({
            constrain: true,
            height: 300,
            title: 'Window',
            width: 300,
            closeAction: 'hide'
        });
        if (win.isVisible() !== true) {
            win.show();
        } else {
            win.close();
        }
    }
}

Answer 1

您可以使用Ext.WindowManager。

Ext.create('Ext.Button', {
  text: 'Click me',
  renderTo: Ext.getBody(),
  listeners: {
    click: function() {
      Ext.WindowManager.each(function(cmp) {
        cmp.close();
      });
      Ext.create('Ext.window.Window', {
        constrain: true,
        height: 300,
        title: 'Window',
        width: 300,
        closeAction: 'hide'
      }).show();
    }
  }
})

var win = new Ext.window.Window({
            constrain: true,
            height: 300,
            title: 'Window',
            width: 300,
            closeAction: 'hide',
            listeners:{
                beforeclose:function(){
                    Ext.Msg.alert('Close','You\'re closing Window',function(){
                        var win2== new Ext.window.Window({
                            constrain: true,
                            height: 300,
                            title: 'Window2',
                            width: 300,
                            closeAction: 'hide'
                        });
                        win2.show();
                    });
                }
            }
        });
        win.show();

您需要将beforeclose事件添加到窗口中。在其中你打电话给新窗口。

Ext.application({
    name: 'Fiddle',
    launch: function() {
        let i = 1;
        function create_window(title) {
            var win = new Ext.window.Window({
                constrain: true,
                height: 150,
                title: 'Window ' + title,
                width: 300,
                closeAction: 'hide',
                listeners: {
                    beforeclose: function (sender, options) {
                        i++;
                        create_window(i);
                        return true;
                    }
                }
            });
            if (win.isVisible() !== true) {
                win.show();
            } else {
                win.close();
            }    
        }
        create_window(i);
    }
});
