我试图根据在类别选择列表中选择的内容将值获取到子类别的选择列表。它似乎不适用于 IE。谁能提出问题？
在我的php文件中
<body onload="setSubcategories(default_value);">
在js文件中我有类似的东西
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)',
'Cars',
'Bikes',
'Car Magazine',
'Bikes Magazine',
'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;
}
最佳答案
尝试使用等效的 DOM:
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);
}
