c# - Textbox onchange event -

-

so have text box, add onchange event of markasexception.

my javascript - 

function markasexception(recordid) {     //alert("exception");      //mark exception column     document.getelementbyid("ctl00_cpmain_lblscrollexception_" + recordid).innertext = "exception";     document.getelementbyid("ctl00_cpmain_lblscrollexception_" + recordid).style.color = "#ff0000";     document.getelementbyid("ctl00_cpmain_tdscrollexception_" + recordid).style.backgroundcolor = "#99ccff";      //enable comments ddl , remove blank (first item)     document.getelementbyid("ctl00_cpmain_ddlcommentid_" + recordid).disabled = false;     document.getelementbyid("ctl00_cpmain_ddlcommentid_" + recordid).focus();     document.getelementbyid("ctl00_cpmain_ddlcommentid_" + recordid).options[0] = null; }

what want is, when user changes value in textbox, mark column "exception", , focus drop down list have chose reason exception.

this happens.. if on text box , change it, tab, tabs drop down list.

however, if change value , click in text box on form, don't focus drop down list.

how accomplish that?

i suggest using jquery's change() function.

the advantage more stable across different browsers.

something like:

    $('#<%= textbox1.clientid %>').change(function(){       // extract recordid textbox - perhaps attribute?       markasexception(recordid);     });

my comment getting longer i'm expanding:

take @ jquery documentation setting page finishes loading. if tb id of textbox selector be

$('#<%= tb.clientid %>')

i suggest replace code , use

tb.attributes.add("recordid", recordid.tostring());

this add id need onto textbox tag. once you're in function outlined above can use following selector recordid in javascript

var recordid = $('#<%= textbox1.clientid %>').attr('recordid');

all together

  $(document.ready(function(){     $('#<%= tb.clientid %>').change(function(){       var recordid = $('#<%= tb.clientid %>').attr('recordid');       if(recordid){         markasexception(recordid);       }     });   });

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...
