Fast learning JavaScript objects-traversing objects

To make it easy to understand the methods that each JavaScript object contains, I write a function.

1 functiongetcollection (obj) {2     Try{3         if(obj) {4             varStype= "";5             varSmessage= "";6              for(varIinchobj) {7                 if(Obj[i] = = =NULL|| Obj[i] = = =undefined) {8Stype= "I";9smessage + = "\ r \ n" +i;Ten                 } One                 Else{ A                     varc =Obj[i]; -                     if(C.name &&c.value) { -smessage + = "\ r \ n" + (C.name + ":" +c.value); theStype= "Name:value"; -                     } -                     Else{ -smessage + = "\ r \ n" + (i + "=" +obj[i]); +Stype= "Obj[i]"; -                     } +                 } A             } atsmessage + = "\ r \ n" + ("Stype:" +stype); - alert (smessage); -         } -     } -     Catch(err) { -Alert ("ERR:" +err.message); in     } -}

View Code

For example, look at the location of all methods and values, can be called by the following JS

GetCollection (location);

The Popup interface is as follows:

You can also view the contents of a JSON : Var json ={"name": "Zhang San", "Depart": "Sales department", "Skill": ["Java", "C + +", "PHP", "C #"]};
GetCollection (JSON);

To view the contents of an array :

var arry =["1", "5", "C"];
GetCollection (Arry);
