Javascript split array into multi array

Question

I'm having a little trouble with using javascript to split an array into a multi array. For instance, I have this array:

[0] => object
 [0] => object
 [0] => The Letter P
 [1] => 5.5
 [1] => object
 [0] => 5
 [1] => 1.1
 [2] => 5
 [3] => 1
 [4] => 1
 [2] => object
 [0] => 5
 [1] => 1.1.1
 [2] => 1.1.1
 [3] => 1.1.1
 [4] => 3

What I would like to do is split up the periods, and create an even deeper array like this:

[0] => object
 [0] => object
 [0] => The Letter P
 [1] => object
 [0] => 5
 [1] => 5
 [1] => object
 [0] => 5
 [1] => object
 [0] => 1
 [1] => 1
 [2] => 5
 [3] => 1
 [4] => 1
 [2] => object
 [0] => 5
 [1] => object
 [0] => 1
 [1] => 1
 [2] => 1
 [2] => object
 [0] => 1
 [1] => 1
 [2] => 1
 [3] => object
 [0] => 1
 [1] => 1
 [2] => 1
 [4] => 3

I have tried just about everything that I can think of and I can't seem to find a code that works :( Please help me :(

• Paul S.: Are the numbers strings or numbers? Test if (~~x !== x) for Number and x.indexOf('.') for String.
• Flauwekeul: The code you posted is not (valid) javascript. I don't know all programming languages but I think it's not valid syntax in any language. Since your question is about javascript: could you show javascript code to clarify your question?
• Bergi: @PaulS.: Is that supposed to do 32-bit-integer-conversion? Just test typeof x
• Paul S.: @Bergi It tests if a Number is not equal to the integer version of itself. If that is true then the number has some non-integer part to it, so special behaviour.
• Bergi: @PaulS.: Ah, it was meant as an answer. I suspected it was related to your question regarding the type of the properties.

Answer 1

This should work

function dotsToArr(arr) {
 for(var x = 0; x < arr.length; x++) {
 if(typeof(arr[x]) != "object") {
 var parts = (arr[x]+"").split(".");
 if(parts.length > 1) {
 arr[x] = parts;
 }
 continue;
 }
 dotsToArr(arr[x]);
 }
}

It's not a complete solution, but I use this function to accomplish something like you're describing.

function parseStringToArray(inputString){
 var parts = inputString.split(".");
 var arr = [];
 while (parts.length){
 arr.push(parts.shift());
 }
 return arr;
}
function parseArray(inputArray){
 var arrayLength = inputArray.length;
 for (var i = 0; i < arrayLength; i++){
 if (inputArray[i].indexOf('.'){
 inputArray[i] = parseStringToArray(inputArray[i]);
 }
 }
}

Would this help?

var toString = Object.prototype.toString;
function parseArray(obj) {
 var i, l;
 if (toString.call(obj) === "[object Number]") {
 obj += "";
 }
 if (toString.call(obj) === "[object String]" && obj.indexOf(".") !== -1) {
 obj = obj.split(".");
 }
 if (toString.call(obj) === "[object Array]") {
 for (i = 0, l = obj.length; i < l; i++) {
 obj[i] = parseArray(obj[i]);
 }
 }
 return obj;
}

thanks for all your replies but I managed to figure it out on my own. It's amazing what happens when you take a break from programming and let your mind go at ease. Anyways, knowing that I have three lays to start within my array, I was able to write the following code:

for(a = 0; a < array.length; a++){
 for(var b = 0; b < array[a].length; b++){
 for(var c = 0; c < array[a][b].length; c++){
 if(array[a][b][c].indexOf(".") > 0){
 array[a][b][c] = array[a][b][c].split(".");
 }
 }
 }
}

At first I tried using while loops, but that required a lot more code and was a lot more confusing. Then I started using the for loop which works a lot better for this type of system. Thanks again for your replies and I hope this helps anyone else who tries to do the same thing.
