javascript-MonkeyPatching:PrimeFaces小部件扩展/覆盖

作者:互联网

我目前正在使用(工作正常)

PrimeFaces.widget.OverlayPanel.prototype._old_init = PrimeFaces.widget.OverlayPanel.prototype.init;
PrimeFaces.widget.OverlayPanel.prototype.init = function(cfg) 
{
    this._old_init(cfg);
    this.align();
}

但我想使用更具可读性和“ jQuery-ish”的功能,例如完全发明的不现实代码:

PrimeFaces.widget.OverlayPanel.patch(
{
    init: function(cfg) 
    {
        super.init(cfg);
        this.align();
    },

    show: function()
    {
        console.log('blah blah blah');
        super.show();
    }
});

我尝试了PrimeFaces.widget.Xxx.extend({…}),但在这种情况下,我无法访问超级方法.

请记住我对Java语言完全不了解

谢谢

解决方法:

我已经做到了:

if(PrimeFaces.widget.OverlayPanel)
{
    PrimeFaces.widget.OverlayPanel = PrimeFaces.widget.OverlayPanel.extend(
    {
        init: function(cfg) 
        {
            this._super(cfg);
            this.align();
        },

        show: function()
        {
            console.log('blah blah blah');
            this._super();
        }
    });
};

这存储在里面

它在全局模板中使用:
