What exactly are parameters in javascript (or any programming language for that matter) -

-

i have piece of code i've written , read in order work correctly must use parameters did , works perfectly, cant figure out life of me parameters , how work. read through ton of articles on web couldn't figure out how parameters work. how 1 parameter know grab instructions another. whole idea frustrating. kind of side question. can getelementby class instead of id or there similar getelementbyid() classes? in advance.

below code in script.js file:

function setvalue(field) {     if(''!=field.defaultvalue)     {         if(field.value==field.defaultvalue)         {             field.value='';         }         else if(''==field.value)         {             field.value=field.defaultvalue;         }     } }

and called script run code below:

<textarea  id="info"             class="textarea"             name="comment"             cols="40" rows="10"             onfocus="setvalue(this)"             onblur="setvalue(this)">                whats name </textarea>

parameters

if "parameter" mean "argument", it's not @ clear mean "how 1 parameter know grab instructions another." arguments/parameters don't grab "instructions" each other.

since it's not @ clear you're asking here, won't go kind of detail, warn function arguments work bit differently in javascript in many other languages c, c#, or java.

the traditional model special memory area called "stack": caller pushes arguments onto stack, , callee (the function being called) pulls them off stack.

javascript doesn't use stack model, though. instead, when function called, object called execution context allocated, , along called variable object, , arguments (and few other things) end being properties on variable object. (this happens invisibly behind scenes, don't direct references either object, fact of them clear edge case behaviors.)

getting elements class name

there's getelementsbyclassname widely-supported except ie. if search "getelementsbyclassname ie" you'll find variety of implementations ie can drop page.

cocoa - Nesting arrays into NSDictionary object (Objective-C) -

-
i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
