i want validate textfield user enter number like.. should start 'arrn' , upto 5 numeric fields. number can be.. arrn1 or arrn12 or arrn123 not arrn123456 5 numeric allowed. can have regex same in javascript validate? i tried regex ['arrn'@[5]] not sure regex syntax. you can use follwong code check pattern. check pattern in onblur event of input. $('input').on('blur',function(){ var val = $(this).val(); if(/^arrn\d{1,5}$/.test(val)) alert('val ok'); else { //$(this).val(''); alert('val not correct.'); } });​ working fiddle

i learning javascript, , bit confused below usage. these question may more javascript d3 specific. http://mbostock.github.com/d3/ex/sunburst.html var arc = d3.svg.arc() .startangle(function(d) { return d.x; }) .endangle(function(d) { return d.x + d.dx; }) .innerradius(function(d) { return math.sqrt(d.y); }) .outerradius(function(d) { return math.sqrt(d.y + d.dy); }); so, startangle, endangle etc takes function argument. rationale being argument function rather number? in full code, no "d" defined.i see in of d3 programs. "d" for? how set or passed? thanks. to first question: the d3.svg.arc object used create slices inside pie diagram. each of these slices needs different start- , end-angle displayed properly. in d3.js not pass in both angles each slice, provide function, takes 1 argument d , corresponding data element slice , returns angles. same holds other parameters set here. another advantage is, datum can consist of multiple pr...

ii using dbi call table on db recurisvly when use prepare function every thing works fine when use prepare_cached instead error message prepare_cached failed below snippet of code sub rec { $data = shift; $dbh = shift; if($x eq 'foo') { return 1; } $query="select x table z =?"; $sth=$dbh->prepare_cached($query); $sth= $dbh->execute($data); while(my ($x)=$sth->fetchrow_array) { $rec($x,$dbh); } } could problem ? the problem iterating on $sth , while doing this, recursing , executing again. since acts on same $sth can't work (prepare_cached call $sth->finish, see dbi docs). so if possible, fetch rows array, $sth->finish , recurse on array. or use normal prepare(). depending on dbs might performant enough.

i have model composite key - row key: public class item { [key, column(order = 0)] public int userid { get; set; } [key, column(order = 1)] public datetime? date { get; set; } } running code below throws exception dbentityvalidationexception message: the date field required. : var = new item { date = null, userid = 2 }; m_entities.items.add(it); m_entities.savechanges(); // throws exception ( m_entities usual dbcontext descendant items defined dbset<item> ) why date required if can null (declared datetime? ) ? , how allow null valid value date ? answer raphael lead me search. here why not possible (answer cobsy): what's wrong nullable columns in composite primary keys? in short: null == null -> false wierd. solution me add id column model. btw: mysql allow me not define primary key, i'm allowed have such schema - ef complains not defining key :-(.
