JavaScript函数命名问题Opera与IE11“ start（）”

Question

I'm having some trouble with this line of code in my HTML :

<input type="button" class="someClass" id="myId" onclick="start()" value="Begin">

In Opera 17 everything works fine, in Internet Explorer 11 I need to rename the onclick function to:

... onclick="startX()" ...

or some other name, but I'm not allowed to use start() , why is this so ? And what does the function start() do in IE11 ?

Answer 1

Thanks to Frédéric Hamidi I did some research about the element and I can confirm that the method .start() and also .stop() belongs to it.

PS: the element is deprecated.

Windows has confusion with certain historic baggage it carries from DOS days. For example you cannot name a file/folder as con is a reserved device name from the DOS era. On the same lines, start is a DOS batch scripting command. I believe that is the reason why IE does not like Javascript function named start .
