To fix the issue you can do There is a form with two required fields , You need to check both on the keyup event:
The Basic Answer:
code :
$(document).ready(function(){

    $("#password").keyup(function(){

        if($(this).val().length > 0 && $("#password_conf").val().length > 0)
            $("#submit").removeAttr("disabled");
        else
            $("#submit").attr("disabled", "disabled");

   });

    $("#password_conf").keyup(function(){

        if($(this).val().length > 0 && $("#password").val().length > 0)
            $("#submit").removeAttr("disabled");
        else
            $("#submit").attr("disabled", "disabled");

    });

});
var minLength = 3;

$(document).ready(function(){

    $("#password").keyup(function(){

        if($(this).val().length >= minLength && $("#password_conf").val().length >= minLength)
            $("#submit").removeAttr("disabled");
        else
            $("#submit").attr("disabled", "disabled");

   });

    $("#password_conf").keyup(function(){

        if($(this).val().length >= minLength && $("#password").val().length >= minLength)
            $("#submit").removeAttr("disabled");
        else
            $("#submit").attr("disabled", "disabled");

    });

});
$("selector").css("css-property", "value");
$("#submit").css("border-color", "blue");
$("#submit").css({"border-color": "blue", "visibility":"visible"});
var minLength = 3;

$(document).ready(function(){

    $("#password").keyup(function(){

        if($(this).val().length >= minLength && $("#password_conf").val().length >= minLength)
            $("#submit").css("visibility", "visible");
        else
            $("#submit").css("visibility", "hidden");

   });

    $("#password_conf").keyup(function(){

        if($(this).val().length >= minLength && $("#password").val().length >= minLength)
            $("#submit").css("visibility", "visible");
        else
            $("#submit").css("visibility", "hidden");

    });

});

it should still fix some issue I have a 32x1 struct array. Each element of this array has several fields. I am trying to check which elements are empty (done), but then I want to create a vector with all the elements that were not empty. , You don't need the loop:
code :
svIdVec = {satdata.SVID};
[svIdVec{~cellfun(@isempty,svIdVec)}]'; % select only the non-empty values
svIdVec = {satdata.SVID}';
svid = ~cellfun(@isempty,svIdVec );
svIdVec = cell2mat(svIdVec(svid));

wish help you to fix your issue var bg_img = curr_elem.style.backgroundImage || curr_elem.style.getAttribute("background-image"); , kinda hokey but it should work...
code :
  var theDiv = document.getElementById('banner-map-225');
  var styleArr = document.getElementsByTagName('STYLE');

  var startPos;
  var endPos;
  var textFromStyle;
  var theImageText;

  for (var i = 0; i < styleArr.length; i++) {
    // find the element selector
    if (styleArr[i].innerHTML.toUpperCase().indexOf(theDiv.id) === -1) {
      // use class name
      startPos = styleArr[i].innerHTML.toUpperCase().indexOf(theDiv.className.toUpperCase());
      if (startPos > -1) {
        startPos = startPos + theDiv.className.length;
      }
    } else {
      // use id
      startPos = styleArr[i].innerHTML.toUpperCase().indexOf(theDiv.id.toUpperCase());
      if (startPos > -1) {
        startPos = startPos + theDiv.id.length;
      }
    }

    if (startPos > -1) {
      // get everything after selector
      textFromStyle = styleArr[i].innerHTML.substring(startPos);

      // find the style def for the element
      startPos = textFromStyle.indexOf('{');
      endPos = textFromStyle.indexOf('}');

      if (startPos > -1) {
        textFromStyle = textFromStyle.substring(startPos, endPos + 1);

        // find bg image def
        startPos = textFromStyle.toUpperCase().indexOf('BACKGROUND-IMAGE');
        endPos = textFromStyle.indexOf(')');

        if (startPos > -1) {
          // get contents of url
          startPos = startPos + ('BACKGROUND-IMAGE').length;
          textFromStyle = textFromStyle.substring(startPos, endPos + 1);
          startPos = textFromStyle.toUpperCase().indexOf('URL(') + ('URL(').length;
          endPos = textFromStyle.indexOf(')');
          if (startPos > -1) {
            theImageText = trimString(textFromStyle.substring(startPos, endPos));
            break;
          }
        }
      }
    }
  }

  // here's your image
  if (theImageText) {
    alert(theImageText);
  }

  // no trim in early IE
  function trimString(sText) {
    return sText.replace(/^\s+|\s+$/g, '');
  }

I wish did fix the issue. This code will check the previous row and, if either the name or date field of that row is empty, a new row won't be added. The alert displays, "Please fill the current row in before adding a new row" but you change the message to anything you like.
code :
var prevName = table.rows[rowCount - 1].cells[1].firstChild.nextSibling.value;
var prevDate = table.rows[rowCount - 1].cells[2].firstChild.nextSibling.value;

if (prevName == "" || prevDate == "") {
    alert("Please fill the current row in before adding a new row");
    return;
}
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);

fixed the issue. Will look into that further Your problem is that you're sending these POST variables as an array, but treating them like a string. You need to loop through each one individually:
code :
<?php
$errors = "";
foreach ($_POST["name"] as $index=>$name) {
    if (empty($name)) {
        $errors .= "Name missing from entry $index.<br/>\n";
    }
}
foreach ($_POST["coming"] as $index=>$coming) {
    if (empty($coming)) {
        $errors .= "Please enter attendance for entry $index.<br/>\n";
    }
}

if ($errors === "") {
    $to = "example@xyz.com";
    $subject = "Wedding RSVP";
    $headers = "From: noreply@adrianandemma.com";
    $body = "The following RSVP has been sent via the website.\n\n";
    foreach($_POST["name"] as $i=>$name) {
        $coming = $_POST["coming"][$i];
        $num = $i + 1;
        $body .= "Name $num : $name\nComing $num : $coming\n\n";
    }
    $body .= "\n\nDate Received: " . date("j F Y, g:i a") . "\n";

    mail($to,$subject,$body,$headers);
}

I wish did fix the issue. You need to first check if is empty then do not push into array otherwise push into the Array. Like this
code :
addFieldValue() {
if (this.newAttribute.employee && this.newAttribute.id) {
  if (this.fieldArray.indexOf(this.newAttribute) === -1) {
    this.fieldArray.push(this.newAttribute)
  }
}
this.newAttribute = {};
console.log(this.fieldArray); }
