string.split（'/'）没有给出正确的数组

Question

I'm having an issue with the following script. The calling script is: script src="//192.168.6.10/js/cYJIeCa30E.js the resulting script needs to be parsed for cYJIeCa30E.js in this script I have:

var scripts = document.getElementsByTagName('script');
var lastScript = scripts[scripts.length-1];
var scriptName = lastScript.src;

var name = scriptName.split('/');
alert(name);

alert(name) gives comma separated values:

http:,,192.168.6.10,js,cYJIeCa30E.js

but

alert(name[4]) gives ':' not the value after the last '/'

any idea what I am missing?

Thanks

The proper way will be like so:

var scripts = document.getElementsByTagName('script');
var lastScript = scripts[scripts.length-1];
var scriptName = lastScript.src;

var a = scriptName.split('/');
alert(a[4]); //cYJIeCa30E.js

Note You can change the variable a to any other variable. Thanks to Mike C for the MDN link
