How to increment a numeric string by +1 with Javascript/jQuery -

-

i have following variable:

pageid = 7

i'd increment number on link:

$('#arrowright').attr('href', 'page.html?='+pageid);

so outputs 7, i'd append link 8. if add +1:

$('#arrowright').attr('href', 'page.html?='+pageid+1);

i following output: 1.html?=71 instead of 8.

how can increment number pageid+1?

try this:

parseint(pageid, 10) + 1

accordint code:

$('#arrowright').attr('href', 'page.html?='+ (parseint(pageid, 10) + 1));

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
