Question

I am working with Raphael JS library. It s been so great and suits the requirements too. I am trying to figure out, how to write a generic event handler for all the nodes in library. I would need the clicked object instance to customize it s attributed on click event.

我已宣布为科安会的拉法尔峡谷,因此,如果有人点击我会利用“Qu子”在本手里接手。我也附上了信道上所有节点的 no。

这里是基因的原型。

$j( #holder ).bind( click , function(event) {

  // event handler.

}

然而,我无法收到被点击的点子的标本。

<代码>event.srcElement属性也失败。

任何帮助都将受到高度赞赏。

Thanks, Karthik.

Answer 1

我认为,问题可能是,当Raphael像你想要得到的东西一样是控制这一产出的原始Raphael数据标的时(而不是实际产出本身),你会利用j Query的点击功能将活动交给DOM/SVG/VERL。

So you probably will get what you want by calling Raphael s own .click() function binding on to the variable you defined when you first called the Raphael function (e.g. the someVar in var someVar = Raphael(xxx...);).

然后,this应当给Raphael的物体(不过,请你在.click(功能(){}内已经界定的变量);可取得更可靠的结果,特别是如果后来你想要。

That s how it works for elements, the same or similar logic would probably follow for the paper/canvas itself.

是否应当使用<代码>。

(according to http://api.jquery.com/category/events/event-object/).
