I have the following array of objects:
[ { "id" : 1, "pricePerDay" : 50, }, { "id" : 2, "pricePerDay" : 70 } ]Based on the user input from a i want to filter either ASC or DESC on thepricePerday. Obviously this would work with:
this.products.sort((a, b) => parseFloat(b.pricePerDay) - parseFloat(a.pricePerDay));BUT i have the variablefilterType which now contains the string'pricePerDay'. How can I use this variable to search the array of objects to properties that have the same key and sort this array based on that key?

- @Wyck no, because in that example you know the key of the object property, in my case I need to search for this key based on the user input, which is the

this.products.sort((a, b) => parseFloat(b[filterType]) - parseFloat(a[filterType]));Does this answer your question?

You can change filterType to field that you want and acs to false if you want desc order
const arr = [ { "id" : 1, "pricePerDay" : 50, }, { "id" : 2, "pricePerDay" : 70 } ] let filterType = 'pricePerDay' let asc = false const res = arr.sort((a, b) => { if (asc) { return parseFloat(a[filterType]) - parseFloat(b[filterType]) } else { return parseFloat(b[filterType]) - parseFloat(a[filterType]) } }); console.log(res)Comments
