Www.abc.com/dc/fda.asp into WWW.ABC.COM/DC/FDA
This problem is very simple if the file suffix is known, as follows:
/.asp$/matches the last. asp, the test code is as follows:
| The code is as follows |
Copy Code |
| < Script type= "Text/javascript" >
function delaspextension (str) {
var reg =/.asp$/;
return Str.replace (Reg, "");
}
var str = ' www.abc.com/dc/fda.asp ';
document.write (delaspextension (str) + ' <br/> ');
</script> If the filename is unknown, use this regular:/.w+$/, the test code is as follows: <script type= "Text/javascript" >
function delextension (str) {
var reg =/.w+$/;
return Str.replace (Reg, "");
}
var str = ' example.com/dc/fda.asp ';
document.write (delextension (str) + ' <br/> ');
var str2 = ' test/regular/fda.do ';
document.write (Delextension (str2) + ' <br/> ');
var str3 = ' example.com/dc/fda.strange_extension ';
document.write (Delextension (STR3) + ' <br/> ');
</script> |
