在javascript中,我可以验证提交时的表单,如下所示:-
<form action="" method="post" onsubmit="return validate(this)">
<input type="text" name="uName" id="uName" />
<input type="password" name="passKey" id="passKey" />
<input type="submit" name="loginBtn" value="login" />
</form>
<script type="text/javascript">
function validate(loginForm){
if(loginForm.uName.value == ''){
alert('Please Enter Username');
loginForm.uName.focus();
}else if(loginForm.passKey.value == ''){
alert('Please Enter Password');
loginForm.passKey.focus();
}else {
return true;
}
}
</script>
我尝试使用下面的 jQuery 代码
<form action="" method="post">
<input type="text" name="uName" id="uName" />
<input type="password" name="passKey" id="passKey" />
<input type="submit" name="loginBtn" value="login" />
</form>
<script type="text/javascript">
$('form').submit(function(loginForm){
if(loginForm.uName.val() == ''){
alert('Please enter username');
loginForm.uName.focus();
}else if(loginForm.passKey.val() == ''){
alert('Please enter username');
loginForm.passKey.focus();
}else {
return true;
}
return false;
});
</script>
但对我不起作用...请帮助我...!
