JavaScript form submitting when not validating -

i'm using next js validate form when submitting:-

function validate() { if( document.square.posx.value == "" ) { alert( "please pick in square think are" ); document.myform.posx.focus() ; homecoming false; } homecoming true; } <form name="square" action="save_results.php" method="post" onsubmit="return validate();"> <input type="text" id="posx" name="posx"> <input type="submit" value="submit"> </form>

when field 'posx' empty , nail submit see alert popup in browser, when click ok form still submits.

how can prevent submitting unless form fields not empty?

thanks

you have copy&paste error in script: see form name: document.square.posx.focus() ;

function validate() { if( document.square.posx.value == "" ) { alert( "please pick in square think are" ); document.square.posx.focus() ; homecoming false; } homecoming true; }
