Well, recently in a variety of direct code debugging, found that the problem may be a little more, let's write down, this essay may be updated from time to time, because I believe different browser differences between a lot.

Directly on the code

1 <HTML>2     <Head>3     </Head>4 5     <Body>6         <Script>7             varStr= "/part1/part2";8             var_list=Str.split (/[\\/]/);9              for(varI= 0; I<_list.length; I++)Ten             { One                 varT= "_list[" +I+ "]  :  " + "\ '" +_list[i]+ "\ '"; A alert (t); -             } -         </Script> the     </Body> - </HTML>

Open FF, Chrome, and IE8 separately to see the results, and find that the result is different

where FF and chrome results are the same

[0] = = "

[1] = ' part1 '

[2] = ' part2 '

And the IE8 is

[0] = ' part1 '

[1] = ' part2 '

So if you use _list by index, there will be different results between natural browsers.

For a different set of code, note that the var str = line of code differs

1 <HTML>2     <Head>3     </Head>4 5     <Body>6         <Script>7             varStr= "part1/part2/";8             var_list=Str.split (/[\\/]/);9              for(varI= 0; I<_list.length; I++)Ten             { One                 varT= "_list[" +I+ "]  :  " + "\ '" +_list[i]+ "\ '"; A alert (t); -             } -         </Script> the     </Body> - </HTML>

FF is still consistent with Chrome's performance,

[0] = ' part1 '

[1] = ' part2 '

[2] = = "

and IE8 is

[0] = ' part1 '

[1] = ' part2 '

The following example is no longer lifted, but one rule that can be found is that IE8 the empty string after the split is swallowed ... This is simply a no-no-words ...

However, when you do not use regular expressions, IE8 is not a problem, pay attention to var _list = Str.split ("/"); Instead of the regular var _list = Str.split (/[\\/]/);

<HTML>    <Head>    </Head>    <Body>        <Script>            varStr= "part1//part2/"; var_list=Str.split ("/");  for(varI= 0; I<_list.length; I++)            {                varT= "_list[" +I+ "]  :  " + "\ '" +_list[i]+ "\ '";            Alert (t); }        </Script>    </Body></HTML>

Well, IE8 again full of blood ...
