What is the best way to place a label within a textfield on a form?

Question

What is the best way to place a label within a textfield on a form?

My textfields display instructions as default values within the textbox. When focused, the text color lightens but only disappears when text is entered. If text is erased, the label reappears. I'm proud of this feature because it's quite seamless. A generic default value just doesn't cut it here, as they disappear on focus.

I have managed to make it work, however, the code has become complex due to negative margins that correspond to individual textfield widths. Ideally, I want a dynamic solution where each label for its corresponding textfield is automatically positioned without intricate coding, likely using a script.

I would greatly appreciate any assistance with this issue but please note I am not interested in default values as a resolution.

Thank you.

Revised for clarity.

An updated edit includes some simple code showcasing the desired effect:

<input style="position: relative; width: 150px; font-size: 10px; font-family: Verdana, sans-serif; " type="text" name="name" id="name"
onfocus="javascript: document.getElementById('nameLabel').style.color='#BEBEBE';"
onkeypress="javascript: if (event.keyCode!=9) {document.getElementById('nameLabel').innerHTML='&nbsp;';}"
onkeyup="javascript: if (this.value=='') document.getElementById('nameLabel').innerHTML='Your&#160;Name';"
onblur="javascript: if (this.value=='') {document.getElementById('nameLabel').style.color='#7e7e7e'; document.getElementById('nameLabel').innerHTML='Your&#160;Name';}"/>
<label id="nameLabel" for="name" style="position: relative; margin-left: -150px; font-size: 10px; font-family: Verdana, sans-serif;">Your Name</label>

Answer №1

My take on this would involve a slightly different strategy (though the core idea is not originally mine, unfortunately I couldn't locate the source for proper credit):

Firstly, leverage the html5 "placeholder" attribute.

Secondly, utilize Modernizr.js to check for placeholder support in the user's browser, along with a basic jQuery script to provide compatibility for browsers lacking native support.

This is how the html structure will appear:

<input type="text" class="placeholder" placeholder="Help Text" />
<textarea class="placeholder" placeholder="Another help text"></textarea>

The corresponding CSS style:

.placeholder{color:#ccc;}

And lastly, the JavaScript implementation:

/* Implementing placeholders for browsers that do not natively support HTML5 <input placeholder='text'>, utilizing Modernizr version 1.5 */
if (!Modernizr.input.placeholder){
    $('input[placeholder], textarea[placeholder]')
        .focus(function() {
            var input = $(this);
            if (input.val() == input.attr('placeholder')) {
                input.val('');
                input.removeClass('placeholder');
            }
        })
        .blur(function() {
            var input = $(this);
            if (input.val() == '') {
                input.addClass('placeholder');
                input.val(input.attr('placeholder'));
            }

        })
        //Execute once during load
        .blur();

    // Clear all 'placeholders' upon form submission
    $('input[placeholder], textarea[placeholder]').parents('form').submit(function() {
        $(this).find('[placeholder]').each(function() {
            var input = $(this);
            if (input.val() == input.attr('placeholder')) {
                input.val('');
            }
        });
    });

If you're looking to create a textbox watermark, you can achieve this without using a label inside the textfield. Instead, modify the content of the textfield when it's empty by applying specific CSS properties. You can then remove this modified text once you click outside the textfield and ensure that if the text matches the watermark text, clear the field again.

Here's a neat little trick I found online:

$(function() {

    // Adding a placeholder to the textbox
    swapValues = [];
    $('.your_input_class').each(function(i){
        $(this).val("Please input xyz");
        swapValues[i] = $(this).val();
        $(this).focus(function(){
            if ($(this).val() == swapValues[i]) {
                $(this).val("").css("color", "#333");
            }
        }).blur(function(){
            if ($.trim($(this).val()) == "") {
                $(this).val(swapValues[i]).css("color", "#ccc");
            }
        });
    });

});

Don't forget to add this code to your input box:

<input class="your_input_class" type="text" value="" />

This script stores the initial input value and changes its color when focused or blurred. Handy, right?

Is it possible to create a similar functionality as demonstrated in this example, but instead of displaying 'required', show the label?

In my approach, I utilized jQuery to set the input value to 'required'. The input is styled with a gray class so that the default text appears lighter.

Update based on feedback

Instead of solely relying on focus, you can alter the input values using keydown and keyup events.

$('.required_input').keydown(function()
{
    if (this.value == 'required')
    {
        $(this).val('').removeClass('gray');
    }
} );

$('.required_input').keyup(function()
{
    if (this.value == '')
    {
        $(this).val('required').addClass('gray');
    }
} );

$('.required_input').blur(function()
{
    if (this.value == '')
    {
        $(this).val('required').addClass('gray');
    }
} );
