javascript - HTML Form Check required="" Before onclick="window.print()" - Stack Overflow

I have a simple web form that, once the submit button has been pressed, checks to see if all required fields have data and then prints.

Here's an example of what I have so far.

<form>
    <span><input value="" required=""/><label>First</label></span>
    <input type="submit" name="submit" value="Submit" onclick="window.print()"/>
</form>

When a user clicks the submit button, the page is sent to the printer. Then once the page has been printed and the user returns to the page, THEN the required check is made by the browser. How can I flip these functions?

Thanks, Alex

• Do you use jQuery in your project? Or are you looking for pure-JS solution to this problem? – Jevgeni Commented Oct 2, 2014 at 14:14
• Why no just write a function and call it? – Steve Commented Oct 2, 2014 at 14:14

Remove your onclick and instead use onsubmit on the form.

<form  onsubmit="window.print();">
    <span><input value="" required=""/><label>First</label></span>
    <input type="submit" name="submit" value="Submit" />
</form>
