Global filter registration
1 general situation
How to officially register the filter:
Export default {data () {return {}, filters: {orderBy () {/ / doSomething}, uppercase () {/ / doSomething}
But when we do a project, most of the filters are used globally, and we don't write them in the component every time we use them. It would be better to extract the global ones. How to officially register the overall situation:
/ / register Vue.filter ('my-filter', function (value) {/ / return the processed value}) / / getter, and return the registered filter var myFilter = Vue.filter (' my-filter')
But decentralized writing is not beautiful, so it can be extracted into a separate file.
2 optimization
We can extract it to a separate file and use Object.keys to register / src/common/filters.js uniformly at the main.js entry
Let dateServer = value = > value.replace (/ (\ d {4}) (\ d {2}) (\ d {2}) / g,'$1) export {dateServer} / src/main.jsimport * as custom from'. / common/filters/custom'Object.keys (custom) .forEach (key = > Vue.filter (key))
Then we can happily use these global filters that we have defined in other. Vue files
{{time | dateServer}}
