    Problem with inheritance

    I am trying to create a custom object, with objects that have objects. My problem is with the last object in the chain (sample), rather than create an additional object for a new value it simply replaces the existing value.

    More specifically this is the structure I am looking for:
    (I have included two sample data sets and my code below)

    Job (only one value)
    Boring (one or more occurrences)
    Sample(one or more occurrences)
    sample properties (20 different properties for each sample)

    74550
    12
    1
    sampledate
    depth
    blows
    .
    .
    .
    2
    sampledate
    depth
    blows
    .
    .
    .

    here is the sample data

    In my code below I can create the jobObject and a variable number of borings. But my "z" variable for creating the samples simply changes the existing sample on each loop.

    Here is my code:
    Code:
    var JobObject = new createJobObj(aReturn)

function createJobObj(aData)
{
	//clientInfo
	this.client = aData[0];
	//jobInfo
	this.job = aData[1]; 

	/*
	---------------------------------
	create a boring array with sample 
	data for each boring
	---------------------------------
	*/
	this.boring = new Object();

	
	for (var i = 2; i < aData.length; i++ )
	{
		var x = aData[i].substr(0,aData[i].indexOf('~'));

		if (x != this.boring)
		{
			this.boring[x] = new Object();
		}

		//add sample data to boring element
		aZ = new Array()
		aZ = aData[i].split('~');
		var z = aZ[1];

		if (z != this.boring[x])
		{
			this.boring[x][z] = new Object();
		}
		this.boring[x][z].sampleDate = aZ[2];
		this.boring[x][z].depth = aZ[3];
		this.boring[x][z].blows = aZ[4];
		this.boring[x][z].contNumb = aZ[5];
		this.boring[x][z].WWofSC = aZ[6];
		this.boring[x][z].DWofSC = aZ[7];
		this.boring[x][z].contWeight = aZ[8];
		this.boring[x][z].moisture = aZ[9];
		this.boring[x][z].sampleInAir = aZ[10];
		this.boring[x][z].sampleInWater = aZ[11];
		this.boring[x][z].water = aZ[12];
		this.boring[x][z].dryUnit = aZ[13];
		this.boring[x][z].corrected = aZ[14];
		this.boring[x][z].dimDryUnit = aZ[15];
		this.boring[x][z].dimCorrected = aZ[16];
		this.boring[x][z].qu = aZ[17];
		this.boring[x][z].qp = aZ[18];
		this.boring[x][z].soilDesc = aZ[19];
	}

      I think it’s line 23. you check, whether this.boring equals x, but you certainly mean, whether x is a subobject of this.boring. (same goes for line 33)

      there are 2 ways on my mind:
      Code:
      if (!(x in this.boring)) {}
if (!this.boring[x]) {} // except if this.boring[x] may be 0, "", false, null, [] or {}

          Of course you are correct, I am looking for a subObject. I had to run the simulation several times before I saw that my problem occurred on line 23.

          I don't seem to be experiencing the problem on line 33 as you suggested and I was having some trouble implementing your suggestions (I believe you say I should use your line #2?

          I am not clear on how I should test for the exceptions you have listed. And on the first go around the subObject has no properties so of course it crashes.

              I see my error. Just repeat your line 1 on my line 33

              Code:
              if (!(z in this.boring[x]))

                  no, both basicly (see comment) do the same.

                  and to be precise, your problem has nothing to do with inheritance, that would involve meddling with the prototype property.
