Share an example code of vue global configuration-H5 Tutorial-php.cn

Today we learn about vue global configuration. I hope it will help us understand the global configuration of vue and develop quickly.

Vue.config is the global configuration object of vue. Contains all global properties of Vue:

The code is as follows:

silent:boolean(默认值：false)----取消Vue的所有的日志与警告 ；用法：Vue.config.silent = true optionMergeStrategies：{[key:string]:Function}(默认是空对象{}） vue.config.optionMergeStrategies._my_option = function (parent, child, vm) { return child + 1 } 自定义合并策略的选项：接受第一个参数是父实例，第二个参数实例为子实例，第三个参数是Vue实例上下文 const Profile = Vue.extend({ _my_option: 1 }) devtools:boolean(默认是true,生成版为false) 用法：Vue.config.devtools = true 配置是否允许vue-devtools检查代码。开发版本默认为：true ,生产为false errorHandler:Funtion （默认值是默认抛出错误）用法： Vue.config.errorHandler = function (err, vm) { // handle error }在指定组件的渲染和观察期间未捕获错误的处理函数。这个处理函数被调用时，可以获取错误信息和vue实例 ignoredELements:array（默认是【】）用法： Vue.config.ignoredElements = [ 'my-custom-web-component', 'another-web-component' ]拼错组件名称，从而抛出一个关于Unknown custom element keyCodes:{[ key:string]:number | Array } (默认是{}）用法：Vue.config.keyCodes = { v:86, F1:112,mediaPlayPause:179,up:[38,87]} 这个多半伴随v-on 自定义键位别名。
