Question

I’m looking for the best solution here, i’ve got an idea but thinking it could be done prettier.

I’m making an simple weather application. And i’m using Yahoo Weather api were they have got codes for weather conditions.

Depending on the condition i’m giving a code. Now, there are 50 codes and i’ve categorised them into 5 categories. In my case ex. my categori Snow contains 15 of Yahoo’s condition codes.

Well, if you got a better idea (which i bet there is) be free to suggest.

My thought is to return the matching value from a set of arrays, but not shure how to do it.

My code now looks like this:

function getCondition(code) {
   var snow = [1, 2, 3],
       sun = [4, 5, 6];
} 

What i need is the variable name that contains the matching number of the code?

I’ve made a JS-Fiddle

Answer 1

Why dont you try an associative array when your key is your variable name and your values is the corresponding code for the variable name, thus your code will be something like this:

var myCodeArray=[];

myCodeArray["snow"]=[1, 2, 3];

myCodeArray["sun"] = [4, 5, 6];

now your method getCondition will be

function getCondition(code) 
{
    for(var definedCodeName in myCodeArray)
    {
      if(myCodeArray.hasOwnProperty(definedCodeName))
      {          
        var array=myCodeArray[definedCodeName ];
        for(var i=0;i<array.length;i++)
        {
            if(array[i]==code){
                return definedCodeName ;}
        }
      }
    }
    return "Not found";
}
