when filter data by using fieldnamefilter variable it give m

work on angular 7 app I face Issue when filter data using data[0][this.fieldnamefilter] it give me N/A

I filter data by using variable fieldnamefilter

below code is give n/a on this.fieldnamefilter function filter :

contentBody:any[];

fieldnamefilter:any; data is have datatype any[];

console.log("data values : " + this.fieldnamefilter ) //result is data values : onlineURL on console log

// when use data[0][this.fieldnamefilter] it give me N/A

this.contentBody = data.filter(item =>item != data[0][this.fieldnamefilter]);

but If I use it as data[0].onlineURL it working ; //working when use field name direct data[0].onlineURL

this.contentBody = data.filter(item =>item != data[0].onlineURL);

so How to solve this issue ;

Updated post I try :

console.log(this.fieldnamefilter it give me onlineURL

when use field name direct it work but on my case i stored filter name on variable

so how to use variable name on data[0].variable have filter

if you store a field in that variable, you can use it like this:

data[0][this.fieldnamefilter] const data = [{onlineurl: 'asdasd'}, {onlineurl: 'xxxx'}];

const fieldnamefilter = 'onlineurl';

const filteredData = data.filter(entry => entry[fieldnamefilter] === data[0][fieldnamefilter
