js模块化

梗概

• 使用CommonJS规范

实例

js needs to require to come in and become an object. There is a tool class util.js in the common directory of hello uni-app. You can search for this example in hello uni-app. Hello uni-app sample code is available from github.

	<script>
		var util = require('../../../common/util.js');  //require这个js模块
		var formatedPlayTime = util.formatTime(playTime); //调用js模块的方法
	</script>

And in this util.js, the previous function should be packaged as a module method and exported (exports). Only exported methods and properties can be called externally, and those not exported belong to internal functions and variables of the module. This is the module specification for es6.

	function formatTime(time) {
		return time;//这里没写逻辑
	}
	module.exports = {
		formatTime: formatTime
	}
