Editor to share with you how vue defines private filters. I hope you will learn something after reading this article. Let's discuss it together.
The methods and concepts of private filters and global filters are the same, except that one can be called globally, while private filters can only be called by themselves.
Global filter point here global filter
The method of use is also the same as the global filter, except that the definition is different.
Global filters are defined through Vue.filter in script
Private filter definition method:
Let vm = new Vue ({el:'#app', data: {}, filters: {/ / current instance private filter}})
In the vm real column, there is a filters at the same level as data, which is used to define the private filter of the current instance.
{{mes | addStr}}
Let vm = new Vue ({el:'#app', data: {mes: "I am a pessimistic person Pessimistic people do pessimistic things "}, filters: {/ / current instance private filter addStr (data,str=" happy ") {return data.replace (/ pessimistic / gmemstr)})
The output is as follows:
If there is a second instance in the page, vm2, to call the filter in vm, it cannot be called.
If there is a global filter and a private filter on the page, it can be called at the same time.
{{mes | setStr | addStr}}
Vue.filter ('setStr',function (data) {return data+' I am the global filter'}) let vm = new Vue ({el:'#app', data: {mes: "I am a pessimistic person Pessimistic people do pessimistic things "}, filters: {/ / current instance private filter addStr (data,str=" happy ") {return data.replace (/ pessimistic / gmemstr)})
Output result:
