为什么我不能这样做？

function name does not exist in the current context is the error it gives me. I want a dynamic ajax call. Why does this happen? I get the handlers are processed server side, but I do not know how to go around this issue.

var getManager = function (functionName, contentDiv) {
    console.log("aircraft manager refresh called");
    $.ajax({
        type: "GET",
        url: '@Url.Action(functionName, "AdminTools")',
        cache: false,
        data: {},
        error: function () {
            alert("An error occurred.");
        },
        success: function (data) {
            $("#".concat(contentDiv)).html(data);
        }
    });
}

I highly recommend you don't couple your server-side and client-side code like:

$.ajax({
    type: "GET",
    url: '@Url.Action(functionName, "AdminTools")',  //THIS

It will turn into a maintenance nightmare. Instead:

<div id="#contentDiv" data-url="@Url.Action(functionName, "AdminTools")">
@* content *@
</div>

then

var getManager = function (functionName, contentDiv) {
  console.log("aircraft manager refresh called");
  var url = contentDiv.data("url");
  $.ajax({
    type: "GET",
    url: url,
    // .....

if you decide later to have multiple contentdivs each can have it's own url, and your code is reusable.
