Utilizing computed properties to implement table filtering in Vue.js

Utilizing computed properties to implement table filtering in Vue.js

I am currently working on a table generated from an array of objects in VuE.js and struggling with implementing computed properties for filtering. I need help figuring out the correct way to use filter() within my computed properties to filter the table based on user input.

new Vue({
  el:"#app",
  data: () => ({
    search:'',
    programs: [],
    editableKeys: ['date', 'company', 'funding', 'funded', 'recruit', 'program'],
  }),
  created () {
    this.getPrograms();
  },
  methods: {
    // Existing methods here
  },
  computed: {
    searchContents(){
      // Filter function implementation needed here
    }
  }
})

Answer №1

When working with computed properties, it is important to remember that they need to return a value just like regular data and props. In the case of filtering results, you simply need to return the filtered result. If there is no specific search criteria specified, you can simply return the raw data without any filters applied.

For example, if you are filtering programs based on their funding attribute, your computed property would look something like this:

computed: {
  searchContents(){
    if (this.search === '') {
      return this.programs
    }

    return this.programs.filter(x => this.search === x.funding)
  }
}

You can then use this computed property within a v-for loop:

<tr v-for="(program, index) in searchContents">
