Jquery Validation plug-in custom error placement

Question

Using the jQuery Validation plug-in for the following form:

<form id="information" method="post" action="#">

            <fieldset>
                <legend>Please enter your contact details</legend>
                <span id="invalid-name"></span>
                <div id="id">
                    <label for="name">Name: (*)</label>
                    <input type="text" id="name" class="details" name="name" maxlength="50" />
                </div>

                <span id="invalid-email"></span>
                <div id="id">
                    <label for="email">Email: (*)</label>
                    <input type="text" id="email" class="details" name="email" maxlength="50" />
                </div>
            </fieldset>
            <fieldset>
                <legend>Write your question here (*)</legend>
                <span id="invalid-text"></span>
                <textarea  id="text" name="text" rows="8" cols="8"></textarea>


            <div id="submission">
                <input type="submit" id="submit" value="Send" name="send"/>
            </div>
            <p class="required">(*) Required</p>
            </fieldset>

             </form>

How can I place the errors inside the span tags? (#invalid-name, #invalid-email, #invalid-text)

I read the documentation about error placement but I did not get how it works. Is it possible to handle each single error and place it in the specified element?

Thank you

You can also manually add error labels in places you need them. In my particular case I had a more complex form with checkbox lists etc. where an insert or insert after would break the layout. Rather than doing this you can take advantage of the fact that the validation script will evaluate if an existing label tag exists for the specified field and use it.

Consider:

<div id="id">
    <label for="name">Name: (*)</label>
    <input type="text" id="name" class="details" name="name" maxlength="50" />
</div>

Now add the following line:

<label for="name" class="error" generated="true"></label>

which is standard error label:

<div id="id">
    <label for="name">Name: (*)</label>
    <input type="text" id="name" class="details" name="name" maxlength="50" />
</div>
<div id="id-error">
    <label for="name" class="error" generated="true"></label>
<div>

jQuery will use this label rather than generating a new one. Sorry I could not find any official documentation on this but found other posts that came across this behaviour.

this is really brilliant solution :) – Gags Jul 19 '16 at 05:25 — Gags, Jul 19 '16 at 05:25

This is a basic structure, you can use whatever selector you would like in the method. You have the error element and the element that was invalid.

jQuery.validator.setDefaults({
    errorPlacement: function(error, element) {
        error.appendTo(element.prev());
    }
});

Or to target the ID, you could do

jQuery.validator.setDefaults({
    errorPlacement: function(error, element) {
        error.appendTo('#invalid-' + element.attr('id'));
    }
});

Not tested, but should work.

Actually, It does not work but it helped me to understand how it works in general! – Paranoid Android Jun 21 '10 at 12:03

I had a similar issue, thanks to the above, I came up with the following: errorPlacement: function(error, element) { errorText = error.text(); element.parent().siblings('.your-help-label').text(errorText); } Hope this helps anyone else who comes across this issue. – Ryan Aug 20 '12 at 04:16

I found that using .insertAfter rather than .appendTo works:

jQuery.validator.setDefaults({
    errorPlacement: function(error, element) {
        error.insertAfter('#invalid-' + element.attr('id'));
    }
});

I'm using the metadata extension with the validator.. (note, I'm setting it to use the data-meta attribute on the markup...)

<input ... data=meta='{
    errorLabel: "#someotherid"
    ,validate: {
        name:true
    }
}' >

then in code...

jQuery.validator.setDefaults({
    errorPlacement: function(error, element) {
        error.appendTo($(
            $(element).metadata().errorLabel
        ));
    }
});

I've been using the metadata for a lot of similar functionality, which works rather nicely... note, I used the single ticks (apostrophes) around the meta data, this way you can use a JSON serializer server-side to inject into that portion of the tag (which should use double-quotes around strings)... a literal apos may be an issue though, (replace "'" with "\x27" in the string).

Here's an example of an input I'm using now... .. jQuery.validate + jQuery.metadata rock... — Tracker1, Nov 04 '10 at 19:27
