如何从立即调用的函数表达式（IIFE）jquery返回带参数的函数

Question

如何在IIFE语法js函数中使用参数返回函数

并在js外面调用

window.app = window.app || {};
window.app.test = app.test || {};

(function ($) {

    var getResult = function (result) {
        return result;
    };
    var handleError = function (result) {
        return result.responseText;
    };
    //data: "{ 'fileName':'"+ fileName +"' }",
     window.app.test.ReadFile = function (fileName) {

        var FileContents = $.ajax({
            type: "GET",
            url: "~/helpers/FilesHelper.aspx/ReadAllContents",
            data: JSON.stringify({ fileName: fileName }),
            cache: false
        });

        FileContents.done(getResult).Fail(handleError);

    };


}(jQuery));

我称之为

window.app.test.ReadFile（ “helpers.txt”）;

您只需返回功能参考

即可

window.app.test.ReadFile = (function ($) {

    var getResult = function (result) {
        return result;
    };
    var handleError = function (result) {
        return result.responseText;
    };
    //data: "{ 'fileName':'"+ fileName +"' }",
    return function (fileName) {

        var FileContents = $.ajax({
            type: "GET",
            url: "~/helpers/FilesHelper.aspx/ReadAllContents",
            data: JSON.stringify({
                fileName: fileName
            }),
            cache: false
        });

        FileContents.done(getResult).fail(handleError);

    };
}(jQuery));
