Demo & Examples

Example Usage

HTML

<input type="text" name="name" placeholder="e.g. John Doe"> <input type="email" name="email" placeholder="e.g. [email protected]"> <input type="url" name="url" placeholder="e.g. https://mathiasbynens.be/"> <input type="tel" name="tel" placeholder="e.g. +32 472 77 69 88"> <input type="password" name="password" placeholder="e.g. h4x0rpr00fz"> <input type="search" name="search" placeholder="Search this site…"> <textarea name="message" placeholder="Your message goes here"></textarea>

jQuery

Use the plugin as follows:

$('input, textarea').placeholder();

By default, .placeholder css class will be added. You can override default by passing the customClass option:

$('input, textarea').placeholder({ customClass: 'my-placeholder' });

You’ll still be able to use jQuery#val() to get and set the input values. If the element is currently showing a placeholder, .val() will return an empty string instead of the placeholder text, just like it does in browsers with a native @placeholder implementation. Calling .val('') to set an element’s value to the empty string will result in the placeholder text (re)appearing.

CSS

The plugin automatically adds class="placeholder" to the elements who are currently showing their placeholder text. You can use this to style placeholder text differently:

input, textarea { color: #000; } .placeholder { color: #aaa; }

I’d suggest sticking to the #aaa color for placeholder text, as it’s the default in most browsers that support @placeholder. If you really want to, though, you can style the placeholder text in some of the browsers that natively support it.

Installation

You can install jquery-placeholder by using Bower.

bower install jquery-placeholder

Or you can install it through npm:

npm install --save jquery-placeholder 

Contributors should install the »dev dependencies« after forking and cloning via npm.

npm install

Notes

  • Requires jQuery 1.6+. For an older version of this plugin that works under jQuery 1.4.2+, see v1.8.7.

  • Works in all A-grade browsers, including IE6.

  • Automatically checks if the browser natively supports the HTML5 placeholder attribute for input and textarea elements. If this is the case, the plugin won’t do anything. If @placeholder is only supported for input elements, the plugin will leave those alone and apply to textareas exclusively. (This is the case for Safari 4, Opera 11.00, and possibly other browsers.)

  • Caches the results of its two feature tests in jQuery.fn.placeholder.input and jQuery.fn.placeholder.textarea. For example, if @placeholder is natively supported for input elements, jQuery.fn.placeholder.input will be true. After loading the plugin, you can re-use these properties in your own code.

  • Using <input type="reset" /> will break the plugin functionality

  • Makes sure it never causes duplicate IDs in your DOM, even in browsers that need an extra input element to fake @placeholder for password inputs. This means you can safely do stuff like:

    <label for="bar">Example label</label> <input type="password" placeholder="foo" id="bar">

    And the <label> will always point to the <input> element you’d expect. Also, all CSS styles based on the ID will just work™.
