javascript 在外部文件中创建jquery函数

Posted 2021-05-03

// create a namespace (an object in the global scope) and attach your function to that
(function () {

    // Initialize namespace 'utilities' (or use existing one if present)
    window.utilities = window.utilities || {};

    // Add function 'myFunction' to the namespace
    utilities.myFunction = function () { ... };

})();



// use the function in a script later like this
var something = utilities.myFunction();
