Is it possible to modify an input field value using CSS upon user interaction?
For example:
<input type=text name=username>
<input type=password name=password>
When the user clicks on this field, I want the initial text to disappear so they can enter their own.
I've attempted the following:
input[value="Input desired username here"] {
styles...
}
Any suggestions or tips?
If you want to display a default value in your input boxes, there is no need to use CSS. You can simply utilize the placeholder attribute like so:
<input type="text" name="username" placeholder="Username" />
It's important to note that not all browsers support the placeholder attribute. If you want to ensure cross-browser compatibility, you can either write some JavaScript code to handle default values in your input-boxes or try this simple and effective solution:
<input type="text" name="username" onFocus="if(this.value=='Username') this.value='';" onBlur="if(this.value=='') this.value='Username';" value="Username" />
This specific technique is known as a placeholder. More recent browsers support the use of a placeholder attribute in this manner:
<input type="text" name="username" placeholder="Enter your desired username here" />
It will display as intended. For older browser compatibility, Modernizr can be used to enable this feature. Here is an example JavaScript implementation:
$(document).ready(function () {
if(!Modernizr.input.placeholder) {
$('[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.val() == input.attr('placeholder')) {
input.addClass('placeholder');
input.val(input.attr('placeholder'));
}).blur();
$('[placeholder]').parents('form').submit(function () {
$(this).find('[placeholder]').each(function () {
var input = $(this);
if (input.val() == input.attr('placeholder')) {
input.val('');
}
})
});
}
})
