I am trying to get the values to a select list for subcategories on

  • 0

I am trying to get the values to a select list for subcategories on the basis on what is chosen in categories select list. It doesn’t seem to work on IE. Can anyone suggest the problem?

In the php file I have

<body onload="setSubcategories(default_value);">

In the js file I have something like

 subcategories = new Array();
 subcategories['Lifestyle'] = ['All',
                                  'Beauty (SHC)',
                                  'Skin Care',
                                  'Hair Care',
                                  'Oral Care',
                                  'Cosmetics',
                                  'Footwear',
                                  'Jewelry',
                                  'Male Styling',
                                  'Women Hygiene',
                                  'Womens magazines',
                                  'Apparels',
                                  ' Fashion (AFA)',
                                  'Spa',
                                  'Accessories'
                                  ];
    subcategories['Automobiles'] = ['All',
                           'Automobiles (C&B)',

                           'Accessories'
                       ];
    subcategories['FoodandBeverage'] = ['All',
                                  'Snacking',
                                  'Confectionary',
                                  'Beverages',
                                  'Generic F&B',
                                  'Restaurant Review',
                                  'Food Reviews',
                                  'Wines & Vineyards'
                              ];


function setSubcategories(default_value){
    default_value = (typeof default_value == 'undefined') ?
             'All' : default_value;
    var elem = document.getElementById('id-category');
    if(elem == null){return false;}

    var category = elem.value;
    var subelem = document.getElementById('id-subcategory');
    var html = "";
    var subcategoriesArr = subcategories[category];
    for(var i=0; i < subcategoriesArr.length; i++){
        var selected = subcategoriesArr[i] == default_value ? " selected" : "";
        html += '<option' + selected + '>' + subcategoriesArr[i] + '</option>\n';
    }
    subelem.innerHTML = html;
}

    Try using DOM equivalent:

    var subcategoriesArr = subcategories[category];
for(var i=0; i < subcategoriesArr.length; i++){
    var option = document.createElement('option');
    option.value = option.text = subcategories[i];
    option.selected = (subcategoriesArr[i] == default_value);
    subelem.appendChild(option);
}
