Add values of previous rows for column jquery -

-

i trying add values of previous rows in column click using jquery. @ moment have following code :

$( document ).ready(function() { $('td').click(function() {     var col = $(this).parent().children().index($(this));     var row = $(this).parent().parent().children().index($(this).parent());     console.log('row: ' + row + ', column: ' + col);     var val1=0;     var val2=0;     var t = document.getelementbyid('hours');     (i = 1; < row; i++)      {          var val1=$(t.rows[i].cells[col]).text();         console.log('row: ' + + ', column: ' + col);         console.log($('#hours tr:eq('+i+') td:eq('+col+')').text);         val2 += number(val1);     } });

});

i've got right column having trouble pulling values. table id : hours

http://jsfiddle.net/biggrecian/0cc2k2zg/

replace

for (i = 1; < row; i++)

with 

for( = 0 ; i<row ; i++)

because otherwise ignores first row

i suggest loop code

var val1 = 0 try {    var txtval1 = t.rows[i].cells[col].textcontent;    val1 = parsefloat(txtval1);    if (isnan(val1)) val1 = 0.0;    // or use parseint , remove isnan test    val2 += val1; } catch(e){ console.log("row:" + +', col: '+col+'can not parse: '+ txtval1); }

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
