Question

I need to parse a table to JSON, I found this solution and it works:

    var tab=[{"value":"1.0","label":"Alabama"},{"value":"2.0","label":"Alaska"},        {"value":"3.0","label":"American Samoa"}];
    var myJsonString = JSON.stringify(tab);  
    var jsonData = $.parseJSON(myJsonString);

The problem is when I declare dynamically the two dimensional table ‘tab’ it doesn’t work:

    var tab_desc1= new Array(3);
    tab_desc1[0]=new Array(2);
    tab_desc1[0]["value"]="1.0";
    tab_desc1[0]["label"]="Alabama";
    tab_desc1[1]=new Array(2);
    tab_desc1[1]["value"]="2.0";
    tab_desc1[1]["label"]="Alaska";
    tab_desc1[2]=new Array(2);
    tab_desc1[2]["value"]="3.0";
    tab_desc1[2]["label"]="American Samoa";
    var myJsonString = JSON.stringify(tab_desc1);    
    var jsonData = $.parseJSON(myJsonString);

Logically my declaration contains error, bur I can’t see it.
Any help! Thanks.

Answer 1

tab_desc1[0] = new Array(2);

Should be

tab_desc1[0] = {};

And same with others.

But I don’t know the purpose of stringify a variable to string and then parse it back.
