I want return true/false from my function when the if condition is met. However it's not returning true, every time it returns false. Please help me. Thanks.
function catExists(cName) {
$("#room_has_cat_table tbody tr td:first-child").each(function(index, item) {
var existingCat = $(this).text();
alert(existingCat);
if (existingCat == cName) {
return true;
}
});
return false;
}
The problem with your logic is because you cannot return a value from an anonymous function.
To correct your logic define a boolean variable which you can update inside the loop when a match is found:
function foo(cName) {
let matchFound = false;
$("#room_has_cat_table tbody tr td:first-child").each(function() {
var existingCat = $(this).text();
if (existingCat == cName) {
matchFound = true;
return; // exit the each() loop
}
});
return matchFound;
}
However, a better approach entirely would be to use filter() to find the match. This avoids the need for the explicit loop:
let matchFound = $("#room_has_cat_table tbody tr td:first-child").filter((i, el) => el.innerText.trim() === cName).length !== 0;
