Placeholder adds support for the "placeholder" input attribute in older browsers.

• Takes the label of form field (input.text or textarea) and uses it as that field's temporary default value.
• Clears the temporary value when the form field is in focus
• If the user clear the text of the field, when the user leaves the field the temporary value reappears
• Optionally you can keep the label from being removed (check the api for more details)
• If the field has already a default value than that value will be used, instead of the temporary label, but the label if exists will be removed.
• When the form is submitted the temporary labels that weren't changes will be replaced with the fields original value, or empty if the field didn't have a default value.

• jQuery 1.7+

To use the application in your project follow the instructions below:

1. Include dist/placeholder.min.js.

2. Add the placeholder attribute to your form elements:

    <input type="text" name="name" placeholder="Your Name" />
    <textarea name="message" placeholder="Write a message"></textarea>
   

3. Instantiate the app:

    $(function () {
        placeholder = new Placeholder();
    });
   

Install node.js and npm.

Run the following from the placeholder directory.

npm install
open test/index.html

Or run the tests in a PhantomJS instance.

brew install phantomjs
grunt mocha

grunt
