I'm using a module called classie.js, whose codes can be viewed below:
/*! * classie - class helper functions * from bonzo https://github.com/ded/bonzo * * classie.has( elem, 'my-class' ) -> true/false * classie.add( elem, 'my-new-class' ) * classie.remove( elem, 'my-unwanted-class' ) * classie.toggle( elem, 'my-class' ) */ /*jshint browser: true, strict: true, undef: true */ /*global define: false */ ( function( window ) { 'use strict'; // class helper functions from bonzo https://github.com/ded/bonzo function classReg( className ) { return new RegExp("(^|\\s+)" + className + "(\\s+|$)"); } // classList support for class management // altho to be fair, the api sucks because it won't accept multiple classes at once var hasClass, addClass, removeClass; if ( 'classList' in document.documentElement ) { hasClass = function( elem, c ) { return elem.classList.contains( c ); }; addClass = function( elem, c ) { elem.classList.add( c ); }; removeClass = function( elem, c ) { elem.classList.remove( c ); }; } else { hasClass = function( elem, c ) { return classReg( c ).test( elem.className ); }; addClass = function( elem, c ) { if ( !hasClass( elem, c ) ) { elem.className = elem.className + ' ' + c; } }; removeClass = function( elem, c ) { elem.className = elem.className.replace( classReg( c ), ' ' ); }; } function toggleClass( elem, c ) { var fn = hasClass( elem, c ) ? removeClass : addClass; fn( elem, c ); } var classie = { // full names hasClass: hasClass, addClass: addClass, removeClass: removeClass, toggleClass: toggleClass, // short names has: hasClass, add: addClass, remove: removeClass, toggle: toggleClass }; //transport if ( typeof define === 'function' && define.amd ) { // AMD define( classie ); } else { //browser global window.classie = classie; } })( window ); And I wrote this in HTML:
<script data-main="js/main.js" src="bower_components/requirejs/require.js"></script> <script src="js/classie.js"></script> Then the browser complains:
[Error] Error: Mismatched anonymous define() module: [object Object] http://requirejs.org/docs/errors.html#mismatch defaultOnError (require.js, line 141) onError (require.js, line 545) intakeDefines (require.js, line 1229) (anonymous function) (require.js, line 1416) What seems weird to me is the last lines in classie.js:
//transport if ( typeof define === 'function' && define.amd ) { // AMD define( classie ); } else { //browser global window.classie = classie; } It looks like classie.js tries its best to keep compatible with AMD because it test whether define is a function and has amd attribute before using it. But unfortunately this caused an error in the browser. Shouldn't requirejs the most famous library that implements AMD? Why doesn't it work?
