Want HTML form submit to do nothing

I want an HTML form to do nothing after it has been submitted.

action=""

is no good because it causes the page to reload.

Basically, I want an Ajax function to be called whenever a button is pressed or someone hits Enter after typing the data. Yes, I could drop the form tag and add just call the function from the button's onclick event, but I also want the "hitting enter" functionality without getting all hackish.

Solution

  • By using return false; in the JavaScript code that you call from the submit button, you can stop the form from submitting.

    Basically, you need the following HTML:

    <form onsubmit="myFunction(); return false;">
    <input type="submit" value="Submit">
</form>

    Then the supporting JavaScript code:

    <script language="javascript"><!--
    function myFunction() {
        // Do stuff
    }
//--></script>

    If you desire, you can also have certain conditions allow the script to submit the form:

    <form onSubmit="return myFunction();">
    <input type="submit" value="Submit">
</form>

    Paired with:

    <script language="JavaScript"><!--
    function myFunction() {
        // Do stuff
        if (condition)
            return true;

        return false;
    }
//--></script>
