Have you ever had troubles signing up in a browser? Let me state an example . You were signing up or trying to log in to a particular browser for a long period of time already then , the browser start refreshing again , as a result, all your sign up information were lost which leads you to do the first step yet again . This kind of problem can be solve through this tutorial. In this tutorial we are going to learn How To Rescue Text and Textarea Values in a Script. So, what is it all about? One of the worst things that can happen when a user is entering the information/data into an <input type="text" /> or <textarea></textarea> element is when you are signing up the form and an accidental reload of the browser happens which causes all the data to be lost. Note: This script only works on <input type="text" /> and <textarea></textarea> elements. The script works in IE6+, FF3.5+, Google Chrome and Safari 4+.

Directions:

First: Kindly add this code below to the HEAD section of your page. 
  1. <script type="text/javascript" src="js/rescuefieldvalues.js">
  2. </script>
Note: Be sure to DOWNLOAD the source code, for the external file it refer in the code above. Second: Just add the simple form to the BODY section of your page. 
  1. <form>
  2. 	<p>
  3. 		Name &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
  4. 		<input type="text" placeholder="Name....." style="width:230px;" />
  5. 	</p>
  6.  
  7. 	<p>
  8. 		Address *&nbsp;
  9. 		<input type="text" id="address" placeholder="Address....." style="width:230px;" />
  10. 	</p>
  11.  
  12. 	<p>
  13. 		Message *
  14. 	<br />
  15. 		<textarea id="message" placeholder="Message....." style="width:300px;height:150px"></textarea>
  16. 	<br />
  17. 		<input type="submit" />
  18. 	</p>
  19.  
  20. 	<p>
  21. 		<a href="javascript:location.reload(true)">
  22. 			Click here to reload the page
  23. 		</a>
  24. 	</p>
  25. </form>
  1. <script type="text/javascript">
  2. //put in the END of your page
  3. //rescuefieldvalues(['id1', 'id2', 'etc'])
  4.  
  5. rescuefieldvalues(['address', 'message']) //rescue data entered for form fields 
  6. "address" and "message"
  7. </script>

For Customizing

To get the script to rescue the information/data in the particular text and textarea fields, first you have to make sure those fields that has individual unique ID in the form.

Example:

  1. <form>
  2. 	<p>
  3. 		Address *&nbsp;
  4. 		<input type="text" id="address" placeholder="Address....." style="width:230px;" />
  5. 	</p>
  6. 	<p>
  7. 		Message *
  8. 	<br />
  9. 		<textarea id="message" placeholder="Message....." style="width:300px;height:150px"></textarea>
  10. </form>
Lastly, after your form and it will be placed at the very end of the document,call the function rescuefieldvalues() with your ID's of those fields you desire to rescue their information/data in the event of a browser refresh or in crash. Note: You can create as many as you can, has a unique ID in the field of <input type="text"> and <textarea><.textarea>. 
  1. <script type="text/javascript">
  2. //put in the END of your page
  3. //rescuefieldvalues(['id1', 'id2', 'etc'])
  4.  
  5. rescuefieldvalues(['address', 'message']) //rescue data entered for form fields 
  6. "address" and "message"
  7. </script>
And that's all!!! The User can rest a little time now knowing that the information/data into the fields of ADDRESS and MESSAGE will still be there if he/she accidentally reload the page or the browser was crash. I hope this simple work, may help you in your project. Practice, and enjoy coding!!!
