Save multiple form values within a single cookie

As someone who is new to JavaScript, I am seeking some guidance.

I came across a code snippet online that allows for saving form input values in separate cookies:

function storeValues(form)  
  {
    setCookie("field1", form.field1.value);
    setCookie("field2", form.field2.value);
    setCookie("field3", form.field3.value);
    setCookie("field4", form.field4.value);
    return true;
  }

Is there a way to modify this code in order to store values from multiple inputs within a single cookie?

Answer №1

One method to save the data is by storing it as JSON format:

function saveData(inputForm)  
{  
    setCookie("formData", JSON.stringify({entry1:inputForm.entry1.value,
                       entry2:inputForm.entry2.value,
                       entry3:inputForm.entry3.value,
                       entry4:inputForm.entry4.value});
    return true;
}

To retrieve the stored information:

JSON.parse(getCookie("formData"));

Answer №2

To store multiple inputs in a cookie, you can combine them into a single string value and then save it. If you're uncertain about the format to use for saving, consider using JSON to structure your values. For instance:

{
   "field1": form.field1.value,
   "field2": form.field2.value,
   "field3": form.field3.value,
   "field4": form.field4.value,
}

If you already have data arranged in a JavaScript structure that's easily accessible, simply pass it to JSON.stringify() before saving it as a cookie.

In case you're certain about the format and know that certain characters won't be present in the values (although this isn't common with form inputs), you could use a character-delimited string. For example, separating values with commas:

string = form.field1.value + "," + form.field2.value + "," + form.field3.value + "," + form.field4.value + ",";

After consolidating the string, proceed to save it in the cookie based on your understanding of the data.

Answer №3

To combine the values, make sure to select a formatting style for separation that will enable you to access the values in the future:

storeCookie( 'fieldname', form.field1.value + ',' + form.field2.value + ','... );
