    Autofill on long forms description

    Asked by ztwersky on September 08, 2014 at 09:02 AM

    Is there a mistake in your text? You write: "For very long forms, higher the better". Don't you mean "Lower the better?" If the form is long, isn't it better to choose a lower number and do an auto-save more often?

    Because saving data on long forms for a short period of time will cause a problem to the browser. There's a script for the auto-save function that is added to the form. That would stop if saving is triggered while the first saving process is still ongoing, and that would cause your browser to hang up.

    Thank you!

    Ok, got it! By the way, what would you call a "long" form? Please look at my longest form and tell me if it qualifies as "long". There are 22 entries in it. I have the autosave set to 20 seconds.


    Thank you.

    Hi, 20 seconds is the safest way possible this is to avoid crash on your browsers. It is the time when to save the data to the browser storage. Doing it multiple times under a lower time frame will surely make the browser hang and end up crashing. That's why if your form had hundreds of questions its recommended to set to a higher value.

    Seeing at your form 4 and 10 seconds is fine. For your information, the auto fill has a feature that it will automatically save your browser session once your user type on an input field or by clicking to a checkbox and radio buttons.

    Remember that this only works on the browser that was used to fill out the form. When you visit your form from another computer it will not load the saved data.
