I'm trying to get array index by value.
I have this code:
var squares = new Array();
for (var i = 1; i <= 160; i++) {
squares.push(i);
}
angular.element('.click').click(function () {
var squareId = angular.element(this).attr('id');
var fisk = squares.indexOf(squareId);
console.log(fisk);
});
This only returns -1, thus, It can't be found. If a replace squareId with a number in indeOf, it works perfect, but if I use a variable, It don't work.
Anyone who can help me?
You are initializing your array values with numbers between 1 and 160, so squares.indexOf(1) for example would return 0.
What you want to do is initialize the array with the actual ids of your elements.
It's because the variable squareId could be returning a string value. The function indexOf can't find the string because it has numbers in the array.
// string search
var squareId = '2';
var fisk = squares.indexOf(squareId);
console.log('This will not be found ' + fisk);
// number search
var squareId = Number('2');
var fisk = squares.indexOf(squareId);
console.log('This will be found ' + fisk);

squares.push('' + i); or i.toString() :) @user500468
