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();
}
});
};
