javascript - Totalling checked checkboxes amidst changes -

-

i have page many checkboxes, each of tied product price. i'm trying use jquery give real-time readout of 1) number of products, , 2) total price of user's selections.

this should easy: have done like:

$(input).change( function(){     var sum = $(input:checked).length     var price_total = $(input:checked).length * 1.99 })

the complication

the element or elements being changed not counted in above code. seems when clicking blank checkbox check it, jquery consider current element 'not checked' rather 'checked', i.e. reflects checkbox before change. result, code gets more complicated accept changed items.

is there elegant , simple way around this?

not sure if code posted you're running, among other things, code missing quotes in $ selectors. however, working me:

$(':checkbox').change( function(){     var sum = $(':checked').length;     var price_total = sum*1.99; })​​

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

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...
