Without the use of Seajs modularity, there is no problem referencing jquery.
Later when using Seajs for modularity, when the introduction of jquery plug-ins, always reported such errors, the online search for the following reasons is probably:
The path to the 1.jquery library file is incorrect, and checking the file path is correct in general to resolve the error.
2. If the path to the library file is correct, then it is possible to load the jquery library file in HTML in the wrong order, which can be resolved if the jquery library file is loaded at the very beginning.
And then put the jquery library file in the HTML there is no this problem, but I still want to use SEAJS to manage jquery, do not want to expose jquery to the outside, then use the following methods:
Write inside the module file:
Window.jquery = window.$ = require ("JQuery");
Tried, feasible, do not know that there is no better way to recommend the solution
about using the Seajs times error: uncaught referenceerror: $ is not defined
