问题
I making a regster form in HTML, with javascript. I Have file Login.js. My browser says the following error: Uncaught ReferenceError: require is not defined.
回答1:
require is a way for different compilers to put in stuff that is needed, later on, while keeping the file small. Did you copy the js file from somewhere else?
You may need to include http://requirejs.org/
Also, this looks incredibly insecure. Are you planning to release this site to the word? or is it just for class/experiment?
As the one comment mentions, if this is supposed to be server-side code, it's not going to work very well on the client side.
回答2:
require is defined in Node.js. Browsers don't have definition for require.
You need to use node module browserify to compile code that uses require for browsers.
Alternatively you can use RequireJS which is file and module loader for browsers.
And remember that normally you can't access files on your disk with javascript due to security reasons.
