<script> $.post("/mobile/user/region/selectProvice", function (res) { if (res== null||res==undefined||res.length<=0){ return false; } $("#province").select({ title: "選擇省份", items: res, onChange: function () { var provinceId = $("#province").attr("data-values"); $("#city").attr("data-values", ""); $("#city").attr("value", ""); $("#county").attr("data-values", ""); $("#county").attr("value", ""); if (provinceId==null||provinceId==undefined||provinceId.trim().length<=0){ return false; } $.post("/mobile/user/region/selectCity?provinceId=" + provinceId, function (res) { if (res== null||res==undefined||res.length<=0){ return false; } $("#city").select("update", {items: res,onChange: function () { var cityId= $("#city").attr("data-values"); $("#county").attr("data-values",""); $("#county").attr("value",""); $.post("/mobile/user/region/selectCounty?cityId=" + cityId, function (res) { $("#county").select("update", {items: res}); }) }}); }) } }) }) $("#city").select({ title: "選擇城市", items: [{}] }) $("#county").select({ title: "選擇縣區", items: [{}] }) function submit() { var regionId = $("#county").attr("data-values"); var regionName = $("#county").attr("value"); layui.sessionData('region', []); layui.data('region', { key: 'regionId', value: regionId }); layui.data('region', { key: 'regionName', value: regionName }); location.href = "/mobile/user/index"; } </script>
iteams不能動態變化，加入，用update這個屬性就可以了。需要給input初始化（不然就會變成輸入框）
$("#county").select("update", {items: res});
input初始化 ，若是iteams 為空的話，會報錯
$("#city").select({
title: "選擇城市",
items: [{}]
})
$("#county").select({
title: "選擇縣區",
items: [{}]
})
