How To Check In Array Vuejs

Question

I have object like this:

data() {
    return {
         headings: ['id','remark'],
         rows: [
            {
              id: 1,
              FirstName: 'Jhon',
              LastName: 'Doe',
              remark: 0
           },
           {
              id: 2,
              FirstName: 'Foo',
              LastName: 'Bar',
              remark: 1
           }
         ]
    }}

Is there away how do i check if key headings object exist in rows object.

Thanks and sorry for my bad english.

I'm trying to understand what you mean. Do you mean you want to know if each of the properties specified in your headings array exists on the objects in the rows array? — Bert

Does this answer your question? Check if value exists in vuejs — showdev

Yes, There's a way

function (row) {
   return this.headings.reduce((res, heading) => res &= row.hasOwnProperty(heading), true)
}

This method should return true - if the row has the heading.

@yong-kim, thanks for your suggestion. I was tried your suggestion. On filters i've make function like this : filters: inArray: function(row) { return this.headings.reduce((res, heading) => res &= row.hasOwnProperty(heading), true) } on my own template like this : <p v-for="r in rows"><div v-for="r in row" v-if="r | inArray">{{r}}</div>/p> I want the result like bellow : <p><div>Jhon</div><div>Doe</div></p><p><div>Foo</div><div>Bar</div></p> If keys in rows = id and remarks, they not print on template
