I put in HTML
console.log(foo["_pristineData"]);
at console I see
value field is unique. I can get value filed by
document.getElementById("blablaInput").value;
it return BAR .
How to get text Bar join stock company based on BAR (what I can get)?
(Return a string, not an object like this question Get JavaScript object from array of objects by value of property The question is not duplicate)
since you're field values are unique so You can use find and return values accordingly, in case you have multiple value and you want to capture all of them you can use filter
const foo =[
{value: 'FOO', text:'some text'},
{value: 'BAR', text: 'Some bar text'}
]
const getValue = () =>{
let value = document.getElementById('id_1').value
let found = foo.find(v=> v.value === value)
let final = found ? found.text : 'Not found'
console.log(final)
}<input id='id_1' value=''></input>
<button onClick='getValue()'>Give me value</button>Use find:
const foo = {
_pristineIndex: [{value: "FOO", text: "Foo limited liability company"},
{value: "BAR", text: "Bar joint stock company"},
{value: "", text: ""}]
};
const { text: res } = foo._pristineIndex.find(({ value }) => value == "BAR");
console.log(res);
Uncaught TypeError: Cannot read property 'find' of undefined_pristineIndex is what I don't know how to get, or I cannot get.
foo["_pristineIndex"].const { text: res } = foo["_pristineIndex"].find(({ value }) => value == "BAR"); imgur.com/a/rp596Jj
foo["_pristineData"][1].textare you asking how to find the index, as thats 100% a dupe.BAR. I can getBARright now, but I don't know how to get its index. Seemly, When I get index success, I can get its text.BAR(fieldvalueis unique, it means 2 or many values are never duplicate.
