Tutorial :jQuery override default validation error message display (Css) Popup/Tooltip like



Question:

I'm trying to over ride the default error message label with a div instead of a label. I have looked at this post as well and get how to do it but my limitations with CSS are haunting me. How can I display this like some of these examples:

Example #1 (Dojo) - Must type invalid input to see error display
Example #2

Here is some example code that overrides the error label to a div element

$(document).ready(function(){              $("#myForm").validate({                  rules: {                      "elem.1": {                          required: true,                          digits: true                      },                      "elem.2": {                          required: true                      }                  },                  errorElement: "div"              });                            });  

Now I'm at a loss on the css part but here it is:

div.error {          position:absolute;          margin-top:-21px;       margin-left:150px;       border:2px solid #C0C097;          background-color:#fff;          color:white;          padding:3px;          text-align:left;          z-index:1;          color:#333333;       font:100% arial,helvetica,clean,sans-serif;       font-size:15px;       font-weight:bold;        }  

UPDATE:

Okay I'm using this code now but the image and the placement on the popup is larger than the border, can this be adjusted to be dynamic is height?

if (element.attr('type') == 'radio' || element.attr('type') == 'checkbox') {     element = element.parent();       offset = element.offset();     error.insertBefore(element)     error.addClass('message');  // add a class to the wrapper     error.css('position', 'absolute');     error.css('left', offset.left + element.outerWidth());     error.css('top', offset.top - (element.height() / 2)); // Not working for Radio, displays towards the bottom of the element. also need to test with checkbox  } else {     // Error placement for single elements     offset = element.offset();     error.insertBefore(element)     error.addClass('message');  // add a class to the wrapper     error.css('position', 'absolute');     error.css('left', offset.left + element.outerWidth());     error.css('top', offset.top - (element.height() / 2));  }  

the css is the same as below (your css code)

Html

<span>  <input type="radio" class="checkbox" value="P" id="radio_P" name="radio_group_name"/>  <label for="radio_P">P</label>  <input type="radio" class="checkbox" value="S" id="radio_S" name="radio_group_name"/>  <label for="radio_S">S</label>  </span>

You can use the errorPlacement option to override the error message display with little css. Because css on its own will not be enough to produce the effect you need.

$(document).ready(function(){      $("#myForm").validate({          rules: {              "elem.1": {                  required: true,                  digits: true              },              "elem.2": {                  required: true              }          },          errorElement: "div",          wrapper: "div",  // a wrapper around the error message          errorPlacement: function(error, element) {              offset = element.offset();              error.insertBefore(element)              error.addClass('message');  // add a class to the wrapper              error.css('position', 'absolute');              error.css('left', offset.left + element.outerWidth());              error.css('top', offset.top);          }        });  });  

You can play with the left and top css attributes to show the error message on top, left, right or bottom of the element. For example to show the error on the top:

    errorPlacement: function(error, element) {          element.before(error);          offset = element.offset();          error.css('left', offset.left);          error.css('top', offset.top - element.outerHeight());      }  

And so on. You can refer to jQuery documentation about css for more options.

Here is the css I used. The result looks exactly like the one you want. With as little CSS as possible:

div.message{      background: transparent url(msg_arrow.gif) no-repeat scroll left center;      padding-left: 7px;  }    div.error{      background-color:#F3E6E6;      border-color: #924949;      border-style: solid solid solid none;      border-width: 2px;      padding: 5px;  }  

And here is the background image you need:

alt text http://sandbox.scriptiny.com/messages/images/msg_arrow.gif

If you want the error message to be displayed after a group of options or fields. Then group all those elements inside one container a 'div' or a 'fieldset'. Add a special class to all of them 'group' for example. And add the following to the begining of the errorPlacement function:

errorPlacement: function(error, element) {      if (element.hasClass('group')){          element = element.parent();      }      ...// continue as previously explained  

If you only want to handle specific cases you can use attr instead:

if (element.attr('type') == 'radio'){      element = element.parent();  }  

That should be enough for the error message to be displayed next to the parent element.

You may need to change the width of the parent element to be less than 100%.


I've tried your code and it is working perfectly fine for me. Here is a preview: alt text

I just made a very small adjustment to the message padding to make it fit in the line:

div.error {      padding: 2px 5px;  }  

You can change those numbers to increase/decrease the padding on top/bottom or left/right. You can also add a height and width to the error message. If you are still having issues, try to replace the span with a div

<div class="group">  <input type="radio" class="checkbox" value="P" id="radio_P" name="radio_group_name"/>  <label for="radio_P">P</label>  <input type="radio" class="checkbox" value="S" id="radio_S" name="radio_group_name"/>  <label for="radio_S">S</label>  </div>  

And then give the container a width (this is very important)

div.group {      width: 50px; /* or any other value */  }  

About the blank page. As I said I tried your code and it is working for me. It might be something else in your code that is causing the issue.

I use jQuery BeautyTips to achieve the little bubble effect you are talking about. I don't use the Validation plugin so I can't really help much there, but it is very easy to style and show the BeautyTips. You should look into it. It's not as simple as just CSS rules, I'm afraid, as you need to use the canvas element and include an extra javascript file for IE to play nice with it.

A few things:

First, I don't think you really need a validation error for a radio fieldset because you could just have one of the fields checked by default. Most people would rather correct something then provide something. For instance:

   Age: (*) 12 - 18 | () 19 - 30 | 31 - 50   

is more likely to be changed to the right answer as the person DOESN'T want it to go to the default. If they see it blank, they are more likely to think "none of your business" and skip it.

Second, I was able to get the effect I think you are wanting without any positioning properties. You just add padding-right to the form (or the div of the form, whatever) to provide enough room for your error and make sure your error will fit in that area. Then, you have a pre-set up css class called "error" and you set it as having a negative margin-top roughly the height of your input field and a margin-left about the distance from the left to where your padding-right should start. I tried this out, it's not great, but it works with three properties and requires no floats or absolutes:

   <style type="text/css">      .error {          width: 13em; /* Ensures that the div won't exceed right padding of form */          margin-top: -1.5em;  /*Moves the div up to the same level as input */          margin-left: 11em;   /*Moves div to the right */          font-size: .9em;     /*Makes sure that the error div is smaller than input */      }       <form>     <label for="name">Name:</label><input id="name" type="textbox" />     <div class="error"><<< This field is required!</div>     <label for="numb">Phone:</label><input id="numb" type="textbox" />     <div class="error"><<< This field is required!</div>     </form>

Unfortunately I can't comment with my newbie reputation, but I have a solution for the issue of the screen going blank, or at least this is what worked for me. Instead of setting the wrapper class inside of the errorPlacement function, set it immediately when you're setting the wrapper type.

$('#myForm').validate({      errorElement: "div",      wrapper: "div class=\"message\"",      errorPlacement: function(error, element) {          offset = element.offset();          error.insertBefore(element);          //error.addClass('message');  // add a class to the wrapper          error.css('position', 'absolute');          error.css('left', offset.left + element.outerWidth() + 5);          error.css('top', offset.top - 3);      }  

});

I'm assuming doing it this way allows the validator to know which div elements to remove, instead of all of them. Worked for me but I'm not entirely sure why, so if someone could elaborate that might help others out a ton.


Solution:5

That answer really helped me, in my case i had to filter some elements out and have special aligment on their error div,

errorPlacement:function(error,element) {      if (element.attr("id") == "special_element") {          // special align      } else { // default error scheme          error.insertAfter(element);      }  }  


Solution:6

Add following css to your .validate method to change the css or functionality

 errorElement: "div",      wrapper: "div",      errorPlacement: function(error, element) {          offset = element.offset();          error.insertAfter(element)          error.css('color','red');      }  


Solution:7

If you could provide some reason as to why you need to replace the label with a div, that would certainly help...

Also, could you paste a sample that'd be helpful ( http://dpaste.com/ or http://pastebin.com/)
