As a UX designer and developer I work with clients of all sorts, and of course I receive all sorts of requests for web dev trickery. The other day I had a client request that stumped me … he had the need to save the users input data from a form so that if they refreshed and did not submit the form would be re-presented with the data that was input by the user. I know crazy, right? Not really, this is actually a great trick for a better user experience.
This ultimately creates a better user experience when filling out forms, not losing their information when refreshing or accidentally hitting the back button.
Here is the solution that worked best for me on how to save input data with jQuery: The first 2 functions set and get the cookies:
function setCookie(c_name, value, exdays) {
var exdate = new Date();
exdate.setDate(exdate.getDate() + exdays);
var c_value = escape(value) + ((exdays == null) ? "" : "; expires=" + exdate.toUTCString());
document.cookie = c_name + "=" + c_value;
}
function getCookie(c_name) {
var c_value = document.cookie;
var c_start = c_value.indexOf(" " + c_name + "=");
if (c_start == -1) {
c_start = c_value.indexOf(c_name + "=");
}
if (c_start == -1) {
c_value = null;
} else {
c_start = c_value.indexOf("=", c_start) + 1;
var c_end = c_value.indexOf(";", c_start);
if (c_end == -1) {
c_end = c_value.length;
}
c_value = unescape(c_value.substring(c_start, c_end));
}
return c_value;
}
After that we need to grab the data being entered by the user and save it:
function saveValue(input) {
var name = input.attr('name');
var value = input.val();
setCookie(name,value);
}
function getValue(input) {
var name = input.attr('name');
var value = getCookie(name);
if(value != null && value != "" ) {
return value;
}
}
Now that you have those functions you can use jQuery to set the cookies with the data entered:
jQuery('input[type="text"], textarea').each(function(){
var value = getValue(jQuery(this));
jQuery(this).val(value);
}).on('blur', function(){
if(jQuery(this).val() != '' ) {
saveValue(jQuery(this));
}
});

Benefits of Using jQuery Cookies for User Experience
One of the main benefits of using jQuery cookies for saving input data is the improved user experience it provides. By storing user input in cookies, you can prevent users from losing their information when they accidentally refresh the page or navigate away from it. This can help reduce frustration for users and improve the overall usability of your website.
Additionally, using jQuery cookies allows for a seamless experience when filling out forms. Users can easily resume where they left off without having to re-enter the same information multiple times. This can save time for users and make the form-filling process more efficient.
Enhancing Form Interactivity with jQuery Cookies
With the ability to save and retrieve input data using jQuery cookies, you can enhance the interactivity of your forms. By automatically populating form fields with previously entered information, you can create a more personalized and user-friendly experience for your website visitors. This can also make your forms more dynamic and engaging, encouraging users to complete them.
Moreover, by utilizing jQuery cookies to store input data, you can easily implement features such as auto-saving drafts or customizing form fields based on user preferences. This level of interactivity can help improve user engagement and conversions on your website.
