Answer 2

注释的BUG..."件"字延长了注释段...

Answer 3

我晕 果然是这个问题 郁闷 楼上的大哥能不能 说明白点
为什么会这样 哈哈 学习下 为什么说 注释的BUG..."件"字延长了注释段...我按你说的 加了 //break bug就可以 郁闷中不能结贴 哈哈 希望 能向你 学习下

Answer 4

你试试把"件"字去掉后
alert(LoadAllEvent);
和没去掉前的比较下就知道了.

Answer 5

貌似和保存编码有关.
当保存文件是用ASNI制式的时候.
"件"和换行符起化学作用了.
把换行符清掉了.

Answer 6

晕 我刚才按你的说 做了  效果一样 汗 不过加上这个  //break bug确实可以 郁闷

Answer 7

 //break bug 
加这个的作用其实是为了把//加换行符把前面的BUG break掉...你试试把文件用记事本打开.存成unicode.
应该会没问题...
