【无限级下拉列表】
[2009-06-13]
在要放置下拉列表的地方放置一控件，一般为隐藏域
以xml为数据源可以用直接调用 xml 形式
var xmldom = loadxml(createxml.ashx?rootid=15&sd=101);
root = xmldom.documentelement;
也可以用ajax调出数据源
var ajax = new xiaofeng.ajaxrequest();
ajax.url = createxml.ashx?rootid=15&sd=101;
ajax.callback = function(e){
if(e.error != undefined)return;
var root = e.responsexml.documentelement;
}
var classselect = new selectclass();
classselect.source = root;
classselect.name = classid;
classselect.firstoption = [[==请选择==,0]];
classselect.selectfirst = true;
classselect.fun = function(e){}
classselect.select = 101;
classselect.run();
参数说明：source 为本下拉列表数据源 为 xmldom
name 为隐藏控件id 一般为隐藏域
firstoption 为下拉列表第一行显示的文字，如果想给每个都有不同的可以设置多个 例如[[==请选择所在的省份==,0],[==请选择所在的市份==,0],[==请选择所在的县份==,0]] 如果 firstoption = 或 firstoption = [] 则不显示这些文字 默认 为[[==请选择==,]]
selectfirst 为是加载完后是否显示要设置的文字 true 为显不 false 为显示数据第一行或设置的行 默认为 true
fun 此函数为每个下拉列表的onchange选择事件触发接口函数
select 为已经选择的属性 默认为
run 为运行此类别
