jsp頁面里的下拉框加載不出下拉框代碼：信息來源：-請選擇-script代碼：$(function(){//頁面加載函數(shù)就會執(zhí)行，頁面加載函數(shù)就會執(zhí)行查詢字典//加載企業(yè)性質(zhì)$.post("${pageContext.request.contextPath}/baseDict_findByTypeCode.action",{"dict_type_code":"007"},function(data){//遍歷JSON數(shù)據(jù)$(date).each(function(i,n){$("#enterpriseNature").append(""+n.dict_item_name+"");});},"json");});控制臺打印顯示能取到值：BaseDictAction中的findByTypeCode方法執(zhí)行了....Hibernate:selectbasedict0_.dict_idasdict_id1_0_,basedict0_.dict_type_codeasdict_typ2_0_,basedict0_.dict_type_nameasdict_typ3_0_,basedict0_.dict_item_nameasdict_ite4_0_,basedict0_.dict_item_codeasdict_ite5_0_,basedict0_.dict_sortasdict_sor6_0_,basedict0_.dict_enableasdict_ena7_0_,basedict0_.dict_memoasdict_mem8_0_frombase_dictbasedict0_wherebasedict0_.dict_type_code=?[{"dict_id":"16","dict_item_code":"","dict_item_name":"私營","dict_type_code":"007","dict_type_name":"企業(yè)性質(zhì)"},{"dict_id":"17","dict_item_code":"","dict_item_name":"國企","dict_type_code":"007","dict_type_name":"企業(yè)性質(zhì)"}]小白跪求大神---

你先看看$("#enterpriseNature")標簽是否加載出來，如果后臺能出來數(shù)據(jù)前臺js也沒有報錯的話，可能是初始化調(diào)用的時候，該標簽還沒初始化完，你把js代碼放在最后面試試

$(function(){//頁面加載函數(shù)就會執(zhí)行，頁面加載函數(shù)就會執(zhí)行查詢字典//加載企業(yè)性質(zhì)$.post("${pageContext.request.contextPath}/baseDict_findByTypeCode.action",{"dict_type_code":"007"},function(data){debugger//遍歷JSON數(shù)據(jù)$(date).each(function(i,n){$("#enterpriseNature").append(""+n.dict_item_name+"");});},"json");});這邊你看看你的data是啥，傳送的是什么東西。你這邊$.each的方法用的好像也不對哦$.each(arr1,function(i,val){})
