javascript multidimensional array creation and insertion

Question

Hello I want to create an array in javascript

var sortValues = array(
                 2 => array(3,4,5),
                 3 => array(5,6,7), 
                 12 => array (7,4,5) 
                 );

Now I am looping through all textboxes of my form. Every textbox has id like 2_3 means 2 will be the main index of the array.

My html markup looks like

<input type="text" value="3" id="2_5" name="2_5">
<input type="text" value="4" id="2_5" name="2_6">
<input type="text" value="5" id="2_5" name="2_7">
<input type="text" value="5" id="3_1" name="3_1">
<input type="text" value="6" id="3_2" name="3_2">
..................................

Now I want to check if 2 exists in array sortValues, I will take the value of the text box and and will check if this value exists in the array against 2 then I will put an alert that value already exists, if value doesn't exists push the value in sub array. Means I need to put 3 against 2 I will check if 3 exists against 2, if yes put alert else push in array.

If 2 (main index) doens't exist create a new index in array and so on. I have tried so far

var sortvalues = new Array();
$(":text").each(function () {
    if($(this).val() != '') {
        id = $(this).attr('id');
        ids = id.split("_");
        parent = ids[0];
        child = ids[1];
        if(typeof sortvalues[parent] !== 'undefined') {
            if(typeof sortvalues[parent][$(this).val()] !== 'undefined') {
                alert("Value already exists");
            } else {
                sortvalues[parent][] = $(this).val();
            }
        } else {
            sortvalues.push(parent);
        }
    }
});
console.log(sortValues);

Which gives ["2", "2", "2"] which is wrong. Can Any body guide me how can I achieve above mentioned array in above mentioned criteria ??/

Answer 1

Do you mean to create an array in another array?

For example :

var sortValues = new Array();
sortValues[2] = Array(3,4,5);

Please clarify your question. And the following:

sortvalues[parent][] = $(this).val()  --> you can't leave empty for the second array.
