Dojo.Connect事件不会被调用 - 为什么? [英] Dojo.Connect Event doesn't get called - why?
问题描述
我正在尝试将 onMouseDown
事件连接到具有 dojo.connect
的图像,如:
I am trying to connect an onMouseDown
event to an image with dojo.connect
like:
dojo.connect(dojo.byId("workpic"), "onMouseDown", workpicDown);
function workpicDown()
{
alert("mousedown");
}
几行之后的类似代码,我连接的地方 onMouse *
事件到 dojo.body
正常工作。
Similar code a few lines later, where I'm connecting onMouse*
events to dojo.body
does work completely properly.
当我点击图像时,我没有看到警报窗口,所以事件没有被调用。为什么是这样?
but when I click on the image, I'm not seeing the alert window, so the event doesn't get called. Why is that?
推荐答案
onMouseDown应该与使用DOM事件而不是Widget事件一起使用。尝试:
"onMouseDown" should be all lower case when used with DOM events as opposed to Widget events. Try:
dojo.connect(dojo.byId("workpic"), "onmousedown", workpicDown);
从文档:
有关事件名称的事件:事件
名称现在是小写,除了
特殊情况(例如,一些Mozilla DOM
事件)。如果您将其关闭(例如
'click'和'onclick')与Dojo相同的
事情,Dojo会将on添加到
事件名称。这不同于
Widget事件在意义上Dijit使用
mixedCase事件名称,以避免
潜在冲突。
A note about the event names: Event names now are lower case, except in special cases (e.g., some Mozilla DOM events). Dojo will add "on" to your event name if you leave it off (e.g., 'click' and 'onclick' are the same thing to dojo). This differs from Widget Events in the sense Dijit uses mixedCase event names, to avoid potential conflicts.
