How to check if the following array if an item exist or not

Hi, please consider the following code, how can I check if Control_ID is already exist in objValidationOutput array if so I should not add it to the array again.

Help please.
function Validate(obj) {
for (var i = 0; i < obj.length; i++) {
        if (obj[i].Validation_Type == 'Required') {
              if (document.getElementById(obj[i].Control_ID).value == '') {
                                                   objValidationOutput[objValidationOutput.length] = new ValidationArray();
                                                   objValidationOutput[objValidationOutput.length-1].Control_ID = obj[i].Control_ID;
                                                   objValidationOutput[objValidationOutput.length-1].Error_Message = obj[i].Error_Message;
                                                   objValidationOutput[objValidationOutput.length-1].Validation_Type = obj[i].Validation_Type;
                                                }
                                            }

How about

function Validate(obj) {
  for (var i = 0; i < obj.length; i++) {
    if (obj[i].Validation_Type == 'Required') {
      var id = obj[i].Control_ID;
      if (objValidationOutput[id] || document.getElementById(id).value != '') continue;
      objValidationOutput[id] = new ValidationArray();
      objValidationOutput[id].Error_Message = obj[i].Error_Message;
      objValidationOutput[id].Validation_Type = obj[i].Validation_Type; // this will ALWAYS be == "Required" so perhaps ignore?
    }
  }
}


now you can do

for (var o in objValidationOutput) { // o is what used to be objValidationOutput[i].Control_ID
  alert(o+':'+objValidationOutput[o].Error_Message;
}
