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.
  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:

  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!!!
