我正在尝试使用 ajax 调用从 web api 带回数据。我写了 2 个类似的函数,但都不起作用。我可以看到数据通过 Fiddler 返回,但对于以下两个函数,它不会进入成功调用。我究竟做错了什么?数据在 Fiddler 的两个函数中返回,只是没有成功。
这是尝试1:
function PopulateDivisions()
{
$.support.cors=true;
$.ajax({
type:'GET',
url:'http://IP/Service/api/DivisionSearch/GetAllDivisions',
data: {},
contentType: 'application/json; charset=utf-8',
dataType: 'jsonp',
success: function(data) {
alert(data);
$("#divisionSelect").append($('<option></option>').val("-99").html("Select One"));
$.each(data, function(i, item){
$("#divisionSelect").append($('<option></option>').val(item.Name).html(item.Name));
});
},
error: function(xhrequest, ErrorText, thrownError) {
alert("Original: " + thrownError + " : " + ErrorText);
}
});
}
错误:未调用 jQuery19102671239298189216_1382022403977:解析器错误
这是 Fiddler 显示的数据返回:
[{"Id":1,"Description":"Executive","Name":"Executive "},{"Id":2,"Description":"ASD","Name":"Administrative Services Division "},{"Id":3,"Description":"COM","Name":"Communications "},{"Id":4,"Description":"CP","Name":"Contracts and Procurement "},{"Id":5,"Description":"PMD","Name":"Program Management Division "},{"Id":6,"Description":"RED","Name":"Research and Evaluation Division "},{"Id":7,"Description":"IT","Name":"Information Technology "}]
这是尝试#2:
function PopulateDivisions2()
{
$.support.cors=true;
$.ajax({
type:'GET',
url:'http://IP/Service/api/DivisionSearch/GetAllDivisionsJsonP',
data: {},
contentType: 'application/json; charset=utf-8',
dataType: 'jsonp',
jsonp: false,
jsonpCallback: "myJsonMethod",
success: function(data) {
//data = JSON.parse(data):
alert(data);
$("#divisionSelect").append($('<option></option>').val("-99").html("Select One"));
$.each(data, function(i, item){
$("#divisionSelect").append($('<option></option>').val(item.Name).html(item.Name));
});
},
error: function(xhrequest, ErrorText, thrownError) {
alert("PopulateDivisions2: " + thrownError + " : " + ErrorText);
}
});
}
错误:未调用 myJsonMethod:parsererror
这是 Fiddler 显示的数据回来了:
"myJsonMethod([{\"Id\":1,\"Description\":\"Executive\",\"Name\":\"Executive \"},{\"Id\":2,\"Description\":\"ASD\",\"Name\":\"Administrative Services Division \"},{\"Id\":3,\"Description\":\"COM\",\"Name\":\"Communications \"},{\"Id\":4,\"Description\":\"CP\",\"Name\":\"Contracts and Procurement \"},{\"Id\":5,\"Description\":\"PMD\",\"Name\":\"Program Management Division \"},{\"Id\":6,\"Description\":\"RED\",\"Name\":\"Research and Evaluation Division \"},{\"Id\":7,\"Description\":\"IT\",\"Name\":\"Information Technology \"}]);"
