下面的代码仅使用“select”作为 jquery 选择器,因此它将影响页面上的所有选择框。你可能想改变这一点。
下面的代码也不能处理选择的选项之一,这可能是您应该注意的。
var type = [{"Id":1,"Name":"This is a name"}];
var subType = [{"Id":2,"ParentId":1,"Name":"This is a name"}];
var output = [];
$.each(type, function(){
//for each type add an optgroup
output.push('<optgroup label="'+this.Name+'">');
var curId = this.Id;
//linear search subTypes array for matching ParentId
$.each(subType, function(k,v){
if( this.ParentId = curId ){
output.push('<option label="'+this.Name +'" value="'+ this.Id +'">'+ this.Name +'</option>');
//DELETE the element from subType array so the next search takes less time
subType.splice(k,1);
}
});
output.push('</optgroup>');
});
//change the 'select' here to the id of your selectbox
$('select').html(output.join(''));
