Check if all elements satisfy a condition

Question

I need a jQuery filter/map/each type function to check if ALL elements satisfy a condition:

function areAllValid(inputs){
     return $.someFunction(inputs,          


        

Answer 1

You don't need to use jQuery to do this. You can do this in native JavaScript using Array.prototype.every, which is supported in IE 9+.

function areAllValid(inputs){
     return inputs.every(function(input) { return input.length > 0; }); 
}

If you are using EcmaScript 2015, you can tidy it up further:

var areAllValid = inputs => inputs.every(input => input.length > 0);
