Below is an example of an HTML form:
<form method="post" action="camount.php" id="loginForm">
<span id="heading">
Username: <input type="text" name='us' id='us'/><br />
Password: <input type="password" name='pa' id='pa'/><br />
</span>
<input type="button" value="Sign in" onclick="isPasswordCorrect(document.getElementById('us'), document.getElementById('pa'))" /><br />
<span class="animated shake" id="report"></span>
</form>
This snippet of JavaScript code is what triggers the function mentioned above
if(xmlhttp.readyState == 4 && xmlhttp.status == 200){
if(xmlhttp.responseText)
document.getElementById("loginForm").submit()
else{
document.getElementById("report").style.webkitAnimationName = "";
setTimeout(function (){
document.getElementById("report").style.webkitAnimationName="animated shake";
}, 0);
var element = document.getElementById('report');
element.innerHTML = "wrong password/username"
password.value = ""
}
}
xmlhttp.open("post", "CheckCred.php", true)
//required for sending data through POST
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded")
xmlhttp.send("name="+encodeURIComponent(name.value)+
"&password="+encodeURIComponent(password.value))
The following CSS should make the text inside the <span> tag turn red and shake. While it does become red, the shaking effect doesn't seem to work.
.animated{
-webkit-animation-fill-mode:both;
-moz-animation-fill-mode:both;
-ms-animation-fill-mode:both;
-o-animation-fill-mode:both;
animation-fill-mode:both;
-webkit-animation-duration:1s;
-moz-animation-duration:1s;
-ms-animation-duration:1s;
-o-animation-duration:1s;
animation-duration:1s;
}
.animated.hinge{
-webkit-animation-duration:2s;
-moz-animation-duration:2s;
-ms-animation-duration:2s;
-o-animation-duration:2s;
animation-duration:2s;
}
@-webkit-keyframes shake {
0%, 100% {-webkit-transform: translateX(0);}
10%, 30%, 50%, 70%, 90% {-webkit-transform: translateX(-10px);}
20%, 40%, 60%, 80% {-webkit-transform: translateX(10px);}
}
@-moz-keyframes shake{
0%, 100% {-moz-transform: translateX(0);}
10%, 30%, 50%, 70%, 90% {-moz-transform: translateX(-10px);}
20%, 40%, 60%, 80% {-moz-transform: translateX(10px);}
}
@-o-keyframes shake{
0%, 100% {-o-transform: translateX(0);}
10%, 30%, 50%, 70%, 90% {-o-transform: translateX(-10px);}
20%, 40%, 60%, 80% {-o-transform: translateX(10px);}
}
@keyframes shake{
0%, 100% {transform: translateX(0);}
10%, 30%, 50%, 70%, 90% {transform: translateX(-10px);}
20%, 40%, 60%, 80% {transform: translateX(10px);}
}
.shake {
-webkit-animation-name: shake;
-moz-animation-name: shake;
-o-animation-name: shake;
animation-name: shake;
}
span#report{
display: block;
color: #F80000;
}
I've attempted to troubleshoot based on guidance from this source but have yet to succeed. I am specifically aiming for this functionality to be operational in FireFox. Any insights on what might be incorrect or why the text "wrong username/password" isn't shaking would be greatly appreciated.
Following a suggestion from MarZab, I also tested out
document.getElementById("report").style.webkitAnimationName = "";
setTimeout(function (){
document.getElementById("report").style.webkitAnimationName = "";
document.getElementById("report").style.webkitAnimationName = "animated shake";
}, 4);
However, the desired shaking effect still fails to materialize.
