在IE中获取json数据有效，但FF和Chrome无效

Question

It seems one of the JSON requests in my mvc app fails when using Firefox but works on IE (and this part seems to work in chrome as well). I thought it might be due to the same-origin policy, but according to my understanding it shouldn't cause any trouble, as all requests use the same host and protocol (in this situation, localhost). When i checked the requests in the net functions of firefox, ie and chrome debuggers, it seems the request made by IE and Chrome is answered with 270b, while the FF request gets only 2b. Any help would be appreciated.

Code:

$(function () {
    // this seems to work fine in FF and IE
    var IncludeTerminatedFlag = getIncludeTerminatedFlag();
    $.getJSON("/Search/GetDebtorList", { DebtorNameCode: '', CountryCode: CountryCode, IncludeTerminatedFlag: IncludeTerminatedFlag }, function (data) {
       // some actions
    });
    // this works fine in FF and IE
    $.getJSON("/Search/GetStaffList", { StaffNameCode: '', CountryCode: CountryCode, IncludeTerminatedFlag: IncludeTerminatedFlag }, function (data) {
        // some actions
    });
    // this works fine in FF and IE
    $.getJSON("/Search/GetStaffList", { StaffNameCode: '', CountryCode: CountryCode, IncludeTerminatedFlag: IncludeTerminatedFlag }, function (data) {
       // some actions
    });

    // this does not work in FF but works in IE
    $.getJSON("/Search/GetClientList", { ClientNameCode: '', CountryCode: CountryCode, IncludeTerminatedFlag: IncludeTerminatedFlag }, function (data) {
      // some actions
    });

}

EDIT: When i tried to debug it under firefox, it seems the laston getJSON call fails? as in it does not go inside the funcion. It also does not work when I try the $ajax syntax

The JSON being returned could be not properly formatted(Chrome is very strict). Try adding error catching to see what the error is in Chrome

$.getJSON("/Search/GetDebtorList", { DebtorNameCode: '', CountryCode: CountryCode, IncludeTerminatedFlag: IncludeTerminatedFlag }, function (data) {
   // some actions
})
.error(function(data) {
  console.log("Error: " + data);
});
