title: jQuery ASP input Validation with Tooltip
body: <p>Currently: successfully executing input validation. The input borders are highlighted red, which is exactly what I need.</p>
  
  <p>The solution was found <a href="https://stackoverflow.com/questions/24429129/textbox-validation-with-jquery">here</a>, but I also need to add a tooltip to any of the fields that are left blank.</p>
  
  <p>I'd also like to fill each tooltip with a message explaining the user error.</p>
  
  <pre><code>function validationHelper() {
     var isValid = true;
     $('#textBox1,#textBox2,#textBox3,#textBox4').each(function () {
          if ($.trim($(this).val()) == '') {
              isValid = false;
              $(this).css({
                  "border": "1px solid red",
                  "background": "#FFCECE"
                  //do I add tooltip property here?
              });
          }
          else {
              $(this).css({
                  "border": "",
                  "background": ""
              });
          }
      });
      if (isValid == false) {
          return false;
      }
      return true;
  }
  </code></pre>
  
  <p>I'd appreciate any suggestions. Thanks in advance.</p>
