[英]FireFox Javascript event handling
I have the following function that works in Chrome/IE 我有以下功能可在Chrome / IE中使用
for(var i = 0; i < 5; ++i) {
document.all["elems" + i].onscroll = getFunc("onScrollAdj(document.all['tb" + i + "']);");
}
function getFunc(jsString) {
return new Function(jsString);
}
However I get ReferenceError: event is undefined
. 但是我得到
ReferenceError: event is undefined
。
I have tried to re-write the function to include an event however I then get another error var i is undefined
. 我试图重新编写函数以包含一个事件,但是随后又遇到另一个错误
var i is undefined
。
document.all["elems" + i].onscroll = onScrollAdj(event, document.all['tb" + i + "');
Is there any way to ensure both event and attributes can be passed? 有什么方法可以确保事件和属性都可以传递?
however I get 'ReferenceError: event' is undefined.
但是我得到'ReferenceError:event'未定义。
That's because you're trying to use event
without declaring it as an argument. 那是因为您尝试使用
event
而不将其声明为参数。 That only works on Microsoft browsers, which make event
a global, and Chrome which throws a bone to Microsoft-only code. 这仅在使
event
成为全局event
的Microsoft浏览器上起作用,而在Chrome浏览器中仅适用于仅Microsoft的代码起作用。 You will need to declare the argument. 您将需要声明参数。
There's no need for new Function
virtually ever, and certainly not in this case: 实际上,几乎不需要
new Function
,在这种情况下当然不需要:
for(var i = 0; i < 5; ++i) {
document.all["elems" + i].onscroll = getFunc(i);
// ------------------------------------------^
}
function getFunc(i) {
// --------------^
return function(event) { onScrollAdj(event, document.all['tb' + i]); };
// -------------^--------------------^
}
Note that you'll have to ensure that onScrollAdj
accepts event
: 请注意,您必须确保
onScrollAdj
接受event
:
function onScrollAdj(event, tbThingy) {
// ------------------^
