未定义-ajax方法错误
大多数问题我都是这样想的,我尝试了很多方法来解决这个问题,但是我做不到未定义-ajax方法错误,ajax,undefined,Ajax,Undefined,大多数问题我都是这样想的,我尝试了很多方法来解决这个问题,但是我做不到 var kullaniciAdi = '<%= Session["kullanici"] %>'; alert(kullaniciAdi); $.ajax({ url: "http://localhost:63000/GetInfoService.asmx/GetInfos", type: "POST", dataType:'json',
var kullaniciAdi = '<%= Session["kullanici"] %>';
alert(kullaniciAdi);
$.ajax({
url: "http://localhost:63000/GetInfoService.asmx/GetInfos",
type: "POST",
dataType:'json',
data: JSON.stringify({ kullaniciAdi: kullaniciAdi }),
contentType: "application/json; charset=windows-1254",
success: function (infos) {
var items = infos.d;
$jQuery.each(items, function (index, val) {
$("div#adSoyad").html('<h1>' + val[index].ad + " " + val[index].soyad + '</h1>');
$("div#fotograf").html('<img src="' + val[index].fotograf + '" class="img-responsive">');
});
},
error: function (e) {
alert(e.leader);
}
});
对不起我的英语:)“不管我做了什么,它都不起作用。”。它怎么不起作用?你犯了什么错误?对不起,先生。这是未定义的错误错误错误的全文是什么?哪一行导致该错误?警告框显示未定义。我认为“var kullaniciAdi=””之后的ajax方法是不正确的部分。错误显示错误:函数(e){alert(e.leader);}当然。否则将成功:)而不是
alert()
使用console.log()
并打开浏览器的调试控制台以查看输出。您将获得更好的调试帮助,并可以检查变量内容。
