<title>Demo: Are You Sure? - a dirty forms jQuery Plugin</title>
<!--
We'll use an old version of jQuery to show we're backwards compatible. In
production we recommend using a later version. e.g.
<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<script src="http://code.jquery.com/jquery-2.1.1.min.js"></script>

<h1>jQuery Plugin Demo: Are You Sure?</h1>
<p>
This page hosts a demo of the <a href="https://github.com/codedance/jquery.AreYouSure">jQuery Are-You-Sure</a> plugin (<code>jquery.are-you-sure.js</code>).
</p>
<p>
<i>Are-you-sure</i> is simple light-weight "dirty forms" JQuery Plugin for modern browsers. It helps prevent users from loosing unsaved form changes.
</p>
<p>
<strong>Features:</strong>
<ul>
<li>Light weight - only the features you need!</li>
<li>Dependency free.</li>
<li>Correct state management - if a user edits then restores a value, the form is not considered dirty.</li>
<li>Easy to understand - less than a "terminal screen" of code!</li>
<li>... and <a href="https://github.com/codedance/jquery.AreYouSure">more</a>.</li>
</ul>
</p>
<h2>Example 1: It's simple!</h2>
<p>
This example shows how easy it is to add a dirty check to your form(s) with one line
of code. (View the page's source)
</p>
<form id="example-1-form" name="coffeeOrder1" method="post">
<h2>Enter Your Coffee Order</h2>
<div>
<label for="example-1-coffee">Coffee</label>
<select name="coffee" id="example-1-coffee">
<option value="espresso">Espresso</option>
<option value="dbl-espresso">Caffe Doppio</option>
<option value="latte">Caffe Latte</option>
<option value="macciato">Machhiato</option>
<option value="cappuccino">Cappuccino</option>
</select>
</div>
<div>
<label>Shots</label><br />
<input type="radio" name="shots" value="1" checked /> 1 Shot - Standard<br />
<input type="radio" name="shots" value="2" /> 2 Shots - Morning wakeup!<br />
<input type="radio" name="shots" value="3" /> 3 Shots - Overdrive!<br />
</div>
<div>
<label for="example-1-sugar">Sugar</label> <input type="text" name="sugar" value="0" id="example-1-sugar" />
</div>
<div>
<label for="example-1-instructions">Special Instructions</label>
<textarea name="instructions" rows="5" id="example-1-instructions"></textarea>
</div>
<div class="buttons">
<input type="checkbox" name="remember" value="true" /> Remember my order<br />
<input type="submit" value="Submit">
<input type="reset" value="Reset">
</div>
<div>
<p>... or visit <a href="http://www.google.com/">Google</a> or close the window without saving!</p>
</div>
</form>
<h2>Example 2: Ignore the unimportant!</h2>
<p>
This example highlights how to disregard a field from the dirty check. In this form
the first field is dynamically populated and hence a change on this field should <em>not</em>
mark the form as dirty.
</p>
<form id="example-2-form" name="coffeeOrder2" method="post">
<h2>Enter Your Coffee Order</h2>
<div>
<!-- The ays-ignore class means a change on this field is not considered "dirty" -->
<label for="pickup">Pickup Time</label>
<input class="ays-ignore" type="text" name="pickup" id="pickup" />
<!-- or you can use a data attribute like this:
<label for="pickup">Pickup Time</label> <input data-ays-ignore="true" type="text" name="pickup" id="pickup" />
-->
</div>
<div>
<label for="example-2-coffee">Coffee</label>
<select name="coffee" id="example-2-coffee">
<option value="espresso">Espresso</option>
<option value="dbl-espresso">Caffe Doppio</option>
<option value="latte">Caffe Latte</option>
<option value="macciato">Machhiato</option>
<option value="cappuccino">Cappuccino</option>
</select>
</div>
<div>
<label>Shots</label><br />
<input type="radio" name="shots" value="1" checked /> 1 Shot - Standard<br />
<input type="radio" name="shots" value="2" /> 2 Shots - Morning wakeup!<br />
<input type="radio" name="shots" value="3" /> 3 Shots - Overdrive!<br />
</div>
<div>
<label for="example-2-sugar">Sugar</label> <input type="text" name="sugar" value="0" id="example-2-sugar" />
</div>
<div>
<label for="example-2-instructions">Special Instructions</label>
<textarea name="instructions" rows="5" id="example-2-instructions"></textarea>
</div>
<div class="buttons">
<input type="checkbox" name="remember" value="true" /> Remember my order<br />
<input type="submit" value="Submit">
</div>
<div>
<p>... or visit <a href="http://www.google.com/">Google</a> or close the window without saving!</p>
</div>
</form>
<h2>Example 3: Lets be intelligent!</h2>
<p>
This is a more advanced example. The <code>dirty</code> and <code>clean</code> change events are
intercepted so the save button is only enabled if the form is dirty (i.e. something to save).
It also demonstrates how to customize the warning message and change the style of a dirty
form (CSS styling using the <code>.dirty</code> class).
</p>
<form id="example-3-form" name="coffeeOrder3" method="post">
<h2>Update My Standard Order</h2>
<div>
<label for="example-3-coffee">Coffee</label>
<select name="coffee" id="example-3-coffee">
<option value=""></option>
<option value="cappuccino">Cappuccino</option>
<option value="espresso">Espresso</option>
<option value="dbl-espresso">Caffe Doppio</option>
<option value="latte">Caffe Latte</option>
<option value="macciato">Machhiato</option>
</select>
</div>
<div>
<label>Shots</label><br />
<input type="radio" name="shots" value="1" /> 1 Shot - Standard<br />
<input type="radio" name="shots" value="2" checked /> 2 Shots - Morning wakeup!<br />
<input type="radio" name="shots" value="3" /> 3 Shots - Overdrive!<br />
</div>
<div>
<label for="example-3-sugar">Sugar</label>
<input type="text" name="sugar" value="1" id="example-3-sugar" />
</div>
<div>
<label for="example-3-instructions">Special Instructions</label>
<textarea name="instructions" rows="5" id="example-3-instructions">No chocolate please</textarea>
</div>
<div class="buttons">
<input type="submit" value="Save" disabled="disabled">
</div>
<div>
<p>... or visit <a href="http://www.google.com/">Google</a> or close the window without saving!</p>
</div>
</form>
<h2>Example 4: Lets be dynamic!</h2>
<p>
In this example we'll dymaically add a field and fire off the <code>rescan</code> event. After
the rescan, Are-You-Sure will start looking for changes on the new fields as well.
</p>
<form id="example-4-form" name="coffeeOrder4" method="post">
<h2>Order Coffee For Pickup Now</h2>
<div>
<a id="example-4-lastorder" href="javascript:void(0);">Set my preferences from my last order</a><br />
</div>
<div>
<label for="example-4-coffee">Coffee</label>
<select name="coffee" id="example-4-coffee">
<option value="cappuccino">Cappuccino</option>
<option value="espresso">Espresso</option>
<option value="dbl-espresso">Caffe Doppio</option>
<option value="latte">Caffe Latte</option>
</select>
</div>
<div id="example-4-special"></div>
<div class="buttons">
<input type="submit" value="Place Order">
</div>
<div>
<p>... or visit <a href="http://www.google.com/">Google</a> or close the window without saving!</p>
</div>
</form>
<h2>Example 5: Edge cases</h2>
<p>
This example demonstrates tracking of hidden and disabled form elements that are changed by non-input elements.
E.g.:
</p>
<ul>
<li>clicking a link or non-input button that changes the value of a hidden form field, or</li>
<li>
clicking a link or non-input button that enables or disables some form fields (which has an effect on whether
or not those fields will be submitted with the form, despite the values not changing).
</li>
</ul>
<form id="example-5-form" name="coffeeOrder5" method="post">
<h2>Update My Standard Order</h2>
<div>
<label for="example-5-coffee">Coffee</label>
<select name="coffee" id="example-3-coffee">
<option value="cappuccino">Cappuccino</option>
<option value="espresso">Espresso</option>
<option value="dbl-espresso">Caffe Doppio</option>
<option value="latte">Caffe Latte</option>
<option value="macciato">Machhiato</option>
</select>
</div>
<div>
<label>Shots</label>
<!--
The visually hidden "shots" radio buttons are disabled and would not normally be submitted with the form.
Clicking the following button will visually show and enable these buttons, resulting in a form state change
(and hence the form is considered dirty) without the values having changed.
-->
<button id="example-5-extra-shots">I want extra shots</button>
<div id="example-5-shots-options" style="display: none;">
<input type="radio" name="shots" value="1" disabled /> 1 Shot - Standard<br />
<input type="radio" name="shots" value="2" disabled /> 2 Shots - Morning wakeup!<br />
<input type="radio" name="shots" value="3" disabled /> 3 Shots - Overdrive!<br />
</div>
</div>
<div>
<label>Do you like us?</label>
<input type="hidden" name="like" value="false" id="example-5-like" />
<button id="example-5-like-button">Like</button>

<h2>Example 6: HTML5 inputs!</h2>

but you need coffee if you're working with HTML5 :-)
