Problem s overovanim – JavaScript, AJAX, jQuery – Fórum – Programujte.com

Hoj,

s JS iba zacinam a nieco mi nejde. Mam JS na overovanie policok ci uzivatel nieco nevynechal, ak hej, vyskoci okno.
No nic nevyskoci, iba web prejde na stranku na ktoru je nasmerovany form action. pls neviete kde je chyba?

JSCode:

function OveritData() {

var problem = 'Nie';

if (document.contact_form.sprava.lenght <= 0) {

  alert("Vyplnte spravu!");

  problem = 'Ano';

}



if (problem == 'Nie'){

return true;

}else{

return false;

}



}

<form name="contact_form" action="index.php" method="post" onsubmit="return OveritData()">

<input type="text" name="email" value="@" onClick="if(this.value=='@')this.value='';" onBlur="if(this.value=='')this.value='@';" class="textBox" style="width: 145px;" /><br><br>

<textarea name="sprava" class="textBox" style="width:145px;height:100px;"></textarea><br><br>

<input type="submit" name="odoslat" class="actionButton" value="Send" />

</form>

if (document.contact_form.sprava.length <= 0) {

z_moravec napsal:

if (document.contact_form.sprava.length <= 0) {

if (document.contact_form.sprava.value.length <= 0) {

z_moravec napsal:

if (document.contact_form.sprava.value.length <= 0){

Druhý pokus :-)
