Remove characters from string

[thankgodfortektips]

Hey All, I have a asp page that has a field that displays a string such as 1234/0/16/0. I need to be able to take this string, remove the number after the first /, add 1 to this number, then put it back in the string.

So 1234/0/16/0 will end up being 1234/1/16/0.

Thanks in advance guys!

a split ought to do that for you

var numString = '1234/0/16/0';

var numArray = numString.split('/');

var newNum = numArray[0] + "/" + (parseInt(numArray[1]) + 1) + "/" + numArray[2] + "/" + numArray[3];

that is untested and could probably be consolodated a bit more, but maybe something along those lines.

Are all of your strings going to be 4 segments long (i.e. always [tt]x1/x2/x3/x4[/tt], never [tt]x1/x2/x3[/tt] or [tt]x1/x2/x3/x4/x5[/tt] )?
If they are, then NorthStarDA's code (above) should be perfect for what you're needing; if not, let us know & someone can work up a function that'll work on a string with a variable number of segments for you.




I hope this helps;

My suggestion will actually add an extra line of code, so I don't know that it's necessarily good for this situation. However, in the event that your string had 1000 slashes in it, this would cut down your code considerably:

[b]using NorthStarDA's code:[/b]

var numString = '1234/0/16/0';
var numArray = numString.split('/');
[gray]//it's good habit to always put a 10 in for the second argument 
//when using parseInt with decimal numbers[/gray]
numArray[1] = parseInt(numArray[1][!], 10[/!]) + 1;
var newNum = numArray[!].join("/")[/!];

or a regex:

var numString = '1234/12/16/0';
alert(numString.replace(/\/[\d]+/,"/1"))


Known is handfull, Unknown is worldfull

thanks guys... i used NorthStarDA code! Worked a treat!

Hey all, just one more question... I need to adapt the code above to just take out the numbers after the first / then add one

So from 1234/9/16/0 I would end up with 10

Thanks again!

no adaptation necessary, the variable numArray[1] holds exactly that value
