问题描述

除Ajax函数之外的简单Web API示例将不会返回成功或错误警报:



http:// localhost:45240 / api / Values / 1

Simple Web API example except the Ajax function will not return a success or an error alert:

http://localhost:45240/api/Values/1

public class ValuesController : ApiController
{
    public IEnumerable<Customer> Get()
    {
        return new List<Customer>(){
            new Customer() { CustomerId = 1, CustomerName = "This" },
            new Customer() { CustomerId = 2, CustomerName = "That" }
        };
    }
    public Customer Get(int id)
    {
        if (id == 1)
        {
            return new Customer() { CustomerId = 1, CustomerName = "This" };
        }
        return null;
    }
}

        $(document).ready(function () {
            $('#Button1').click(function () {
                $.ajax({
                    url: 'http://localhost:45240/api/Values/1',
                    type: 'GET',
                    contentType: 'application/json; charset=utf-8',
                    data: '{}',
                    datatype: 'json',
                    success: function (data){
                        alert("works");
                    },
                    error: function (x, e) {
                        alert("Error: " + x.responseText);
                    }
                });
            });
        });
</script>
    <asp:Button ID="Button1" runat="server" Text="Button" />

推荐答案

(document).ready(function() {
(document).ready(function () {


('#Button1')。click(function(){
('#Button1').click(function () {


.ajax({
url:'http:// localhost:45240 / api / Values / 1',
类型:'GET',
contentType:'application / json; charset = utf-8',
data:'{}',
datatype:'json',
success:function(data){
alert(works);
},
错误:function(x,e){
alert(错误:+ x.responseText);
}
});
});
});
< / script >
< asp:按钮 ID = Button1 runat = server 文字 = 按钮 / >
.ajax({ url: 'http://localhost:45240/api/Values/1', type: 'GET', contentType: 'application/json; charset=utf-8', data: '{}', datatype: 'json', success: function (data){ alert("works"); }, error: function (x, e) { alert("Error: " + x.responseText); } }); }); }); </script> <asp:Button ID="Button1" runat="server" Text="Button" />
