HTML5 Forms: JavaScript and the Constraint Validation API

HTML5 Forms: JavaScript and the Constraint Validation API

Core points HTML5 allows client form validation to be free of JavaScript encoding, but for more complex forms, JavaScript and constraint validation APIs can be used to enhance native validation.

The Constraint Validation API provides some methods and properties, such as .willValidate, .checkValidity(), .validity, and .setCustomValidity(). These are used to check whether the verification field is to be validated, the verification field is to be validated, and to set the validity of the field.

Building a Library with RequireJS

Building a Library with RequireJS

Key Points RequireJS is an AMD module loader for browsers that asynchronously load scripts and CSS files, manage dependencies and build code structures. It also includes an optimization tool for production environments. When using RequireJS, the code needs to be wrapped in the module definition. Modules can be referenced in other modules, and all dependencies will be loaded before the module itself is loaded. RequireJS optimizer r.js can be configured to build all modules into a single file. This configuration can also make the module an independent global library, both as an AMD module and as a global export in the browser. RequireJS can be used to build libraries and applications that use them.

QUnit.start() is used to start or resume running tests after the test is stopped, while QUnit.stop() increases the number of QUnit.start() calls that the test runner must wait before continuing.
