首先看下界面：
说到select联动，我就想到用ajax获取数据加载出来。
然后就开始写，select被改变的时候，触发ajax去后台找数据，数据要自己下级分类数据和当前选择分类的商品数据。
写完之后，发现有些重复代码，获取商品这个数据，接口和js获取数据循环遍历代码好几处重复，触发三次选择框事件，都要获取对应分类的商品数据，所以要抽离出来。
前端js代码：
第一个选择框：
$("#pcate").change(function () {
var pcate = this.value;
$.getJSON(‘{php echo webUrl("order/print/ajaxCcate")}‘,{pcate:pcate},function (res) {
if(res.status == 0){
var data = res.result;
var html = ‘<option value="" selected>全部</option>‘;
if(data != ‘‘){
$.each(data,function(index, category){
html += ‘<option value="‘ + category[‘id‘] + ‘" >‘ + category[‘name‘] + ‘</option>‘;
})
}
getGoods();
$("#ccate").html("");
$("#ccate").html(html);
$("#tcate").html("<option value=‘‘ selected>全部</option>");
}else{
$("#ccate").html("<option value=‘‘ selected>全部</option>");
$("#tcate").html("<option value=‘‘ selected>全部</option>");
$("#title").html("<option value=‘‘ selected>全部</option>");
}
})
})
第二个选择框：
$("#ccate").change(function () {
var ccate = this.value;
var pcate = $("#pcate").val();
$.getJSON(‘{php echo webUrl("order/print/ajaxTcate")}‘,{ccate:ccate,pcate:pcate},function(res){
if(res.status == 0){
var data = res.result;
var html = ‘<option value="" selected>全部</option>‘;
if(data != ‘‘){
$.each(data,function (index, category) {
html += ‘<option value="‘ + category[‘id‘] + ‘" >‘ + category[‘name‘] + ‘</option>‘;
})
}
getGoods();
$("#tcate").html("");
$("#tcate").html(html);
}else{
getGoods();
$("#tcate").html("<option value=‘‘ selected>全部</option>");
}
})
})
第三选择框：
$("#tcate").change(function () {
getGoods();
})
获取商品：
function getGoods(){
var p = $("#pcate").val();
var c = $("#ccate").val();
var t = $("#tcate").val();
$.getJSON(‘{php echo webUrl("order/print/getGoods")}‘, {tcate:t,pcate:p,ccate:c}, function(res){
if(res.status == 0){
var data = res.result;
var html = ‘<option value="" selected>全部</option>‘;
if(data != ‘‘){
$.each(data,function (index, category) {
html += ‘<option value="‘ + category[‘id‘] + ‘" >‘ + category[‘title‘] + ‘</option>‘;
})
}
$("#title").html("");
$("#title").html(html);
}
后台接口：
public function ajaxCcate(){
global $_GPC,$_W;
$pcate = intval($_GPC[‘pcate‘]);
if(empty($pcate)){
return show_json(1);
}
$ccate = pdo_fetchall(‘SELECT name,level,id FROM‘.tablename(‘ewei_shop_category‘).‘WHERE uniacid = :uniacid AND parentid = :parentid AND level = 2 ORDER BY displayorder DESC‘,array(‘:uniacid‘=>$_W[‘uniacid‘],‘:parentid‘=>$pcate));
show_json(0,$ccate);
}
public function ajaxTcate(){
global $_GPC,$_W;
$ccate = intval($_GPC[‘ccate‘]);
if(empty($ccate)) return show_json(1);
$tcate = pdo_fetchall(‘select name,id from‘.tablename(‘ewei_shop_category‘).‘where uniacid = :uniacid and parentid = :parentid and level = 3 order by displayorder desc‘,array(‘:uniacid‘=>$_W[‘uniacid‘],‘:parentid‘=> $ccate));
show_json(0,$tcate);
}
public function getGoods(){
global $_GPC,$_W;
$con = ‘‘;
$tcate = intval($_GPC[‘tcate‘]);
$pcate = intval($_GPC[‘pcate‘]);
$ccate = intval($_GPC[‘ccate‘]);
if(!empty($pcate)) $con .= ‘ and pcate = ‘.$pcate;
if(!empty($ccate)) $con .= ‘ and ccate = ‘.$ccate;
if(!empty($tcate)) $con .= ‘ and tcate = ‘.$tcate;
$sql = ‘select title,id from‘.tablename(‘ewei_shop_goods‘).‘where uniacid = ‘.$_W[‘uniacid‘].$con;
$title = pdo_fetchall($sql);
show_json(0,$title);
}
