here's step through of javascript. i have htmlcollection, want loop through , extract object id of fileuploadcontrol. how do it? here's code, how proceed? function uploadimage(lnk) { var row = lnk.parentnode.parentnode; var rowindex = row.rowindex - 1; var abc = row.cells[2].getelementsbytagname("input"); var arr = [].slice.call(abc); } this it: abc.nameditem('fileuploadcontrol') but beware that: different browsers behave differently when there more 1 elements matching string used index (or nameditem's argument). firefox 8 behaves specified in dom 2 , dom4, returning first matching element. webkit browsers , internet explorer in case return htmlcollection , opera returns nodelist of matching elements. from here . this means if in markup had this: <div id='id'>foo</div> <div id='id'>bar</div> browsers behave differently when executing following code...

i'm working on large project, cross platform between linux , osx. i'm include boost functionalities, don't want force the collaborators install on machine (with totally different environment) boost libraries. if compile boost on machine, , put static libraries inside repository, problem face? can colleagues use same static libraries on environment? afaik there difference. static libraries not same on os x , linux. compilation depends on toolset (see boost guide ). , there can issues if ides different. however can compile both versions 1 platform (see cross-compilation ) , put them in repository, putting binary objects not best idea (even if don't depend on platform). i think try compile , link boost on different platforms, maybe succeed, can not cover scenarios sure. better create boost compilation script , tell use it.

in python, there nice method simplifies creation of strings, making code beautiful , readable. for example, following code print exampleprogram -e- cannot something print_msg('e', 'cannot something') def print_msg(type, msg): print 'exampleprogram -{0}- {1}'.format(type, msg) i.e. can specify "slots" within string, using {x} syntax, x parameter index, , returns new string, in replaces these slots parameters passed .format() method. currently java knowledge, implement such method ugly way: void printmsg(string type, string msg) { system.out.println("exampleprogram -" + type + "- " + msg); } is there equivalent python's .format() string method? messageformat has exact usage. int planet = 7; string event = "a disturbance in force"; string result = messageformat.format( "at {1,time} on {1,date}, there {2} on planet {0,number,integer}.", planet, new date(), eve...

i have blocks of pseudo-code text stored in database printed off line-by-line , displayed in html. pseudo-code entered in text column in database: while (counter <= 10) { printf("enter grade: "); scanf("%d", &grade); total = total + grade; counter = counter + 1; } /* end while */ controller: def index @code = code.first // filler time being end index: - @code.cont.each_line |line| - += 1 .line %span= %li.line= line - = 0 somewhere along way ruby automatically strips out whitespace , leaves me text. i'd know how preserve this: while (counter <= 10) { printf("enter grade: "); scanf("%d", &grade); total = total + grade; counter = counter + 1; } /* end while */ doesn't come out this: while (counter <= printf("enter grade: "); scanf("%d", &grade); total = total + grade; counter = counter + 1; } /* end while */ i'm pretty...
