What is the best way to clear a text field when it contains zero on focus, and set it back to zero if it's empty on focus out? How can this be implemented globally for every text field by adding a common class to all text fields?

Enhance user experience with blur and focus functionality
$('textarea').on('focus', function () {
if ($(this).val() == "0") {
$(this).val("");
}
});
$('textarea').on('blur', function () {
if ($(this).val() == "") {
$(this).val("0");
}
});
While some suggestions presented here are promising, I personally do not favor using JavaScript as a solution for this issue unless it is necessary to support older browser versions.
It's worth noting that both input and textarea fields offer the placeholder attribute.
<input type="text" placeholder="0">
By utilizing this feature, the browser itself handles displaying the placeholder value of 0 effortlessly.
When referring to textfield, I assume you are talking about individual text fields and not text areas.
To handle them globally at the document level (or any parent element), utilize a selector within the on method.
$(document).on('focusout', 'input[type=text]', function(){
var $input = $(this);
if ($input.val() == "")
{
$input.val("0");
}
}).on('focus', 'input[type=text]', function(){
var $input = $(this);
if ($input.val() == "0")
{
$input.val("");
}
});
