嗨，我尝试向我的 Web 服务发送参数以获取数据。但我总是得到一个错误：[对象错误]
那个错误是什么意思？
到目前为止，Web 服务正在运行。如果我在浏览器中调用 Web 方法，我会得到所有数据。
我做错了什么。我尝试了很多东西，但没有任何帮助..希望你能帮助我
我的查询：
function loadDate() {
jQuery.support.cors = true;
PanelID = document.getElementById('PanelID').value;
alert(PanelID);
jQuery.ajax({
type: "POST",
url: "http://nexxt-entwicklung.de/Web/Service1.asmx/getDatetime",
data: "{ 'PanelID': '" + PanelID + "' }",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
alert("Success: " + msg.d);
},
error: function(msg) {
alert("Failed: " + msg.status + ": " + msg.statusText);
}
});
}
