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

Not exactly, but it's easy to create one:

    $.eachCondition = function (obj, conditionFunction){
        var trueCount=0;
        var falseCount=0;

        $.each(obj, function (i,v) {
          if (conditionFunction.call(this,i,v)) {
            trueCount++;
          }
          else {
            falseCount++;
          }
          });
          if (falseCount===0) {
            return true;
          }
          if (trueCount===0) {
            return false;
          }
          return undefined;
      };
      $.fn.eachCondition = function (conditionFunction) {
        return $.eachCondition(this, conditionFunction);
      };

Quick little jQuery :

$(document).ready(function() {
  $('form input').keyUp(function() {
    var allValid = true;
    $.each($('form input'), function(input) { 
      allValid = input.val().length > 0 
    }
    if ( allValid )
      ...
    else
      ...
  })
});
