I've wrote a script which uses a bunch of data and building a grid where you are able to move through with the arrowkeys and tab.
While testing it in a seperate file everything works fine. After adding it to my Website the script works pretty well in Chrome, Opera, Safari and IE. But in Firefox my focus jumps out of the grid and went to the adressbar. Using the same Data in my testfile, there is no error like this.
What could be a reason why it does not work in Firefox? I got no Errors in Firebug.
Its a file with more then 2500 lines...Here is the part where the navigation with Tab starts:
$(document).keydown(function (e) {
switch (e.keyCode) {
case 9:
if (editing == true) {
e.preventDefault();
var direction = "right";
if (e.shiftKey) {
direction = "left";
}
root.gridSave();
root.moveMark(direction);
var checker = true;
var c = 0;
while (checker) {
if (!clickTarget) {
if (newLine == true) {
root.markNewLineFirstCell();
root.scrollVert();
} else {
root.moveMark("right");
}
}
if (!clickTarget.hasClass("editable")) {
root.moveMark(direction);
if (c > root.captions.length) {
checker = false;
}
c++;
} else {
editMode = false;
root.edit(clickTarget);
root.setFocus(clickTarget);
checker = false;
}
}
} else {
e.preventDefault();
if (editMode == true) {
direction = "right";
if (e.shiftKey) {
direction = "left";
}
root.moveMark(direction);
root.scrollVert();
}
}
break;
}
});

In Adobe Animate HTML5 Canvas (Create.js/Easel.js), I am trying to set the state of a button, but not working with various code:
this.retinoscopeButton.addEventListener("click", retinoscope.bind(this));
/*function retinoscope(evt) {
var retinoscopeButtonState = evt.currentTarget.state = !evt.currentTarget.state;
if (retinoscopeButtonState) {
alert(retinoscopeButtonState);
this.retinoscopeButton.upState = this.retinoscopeButton.downState;
} else {
this.retinoscopeButton.downState = this.retinoscopeButton.upState;
}
}*/
var retinoscopeButtonState = 'up';
function retinoscope(evt){
if (retinoscopeButtonState == 'up'){
this.retinoscopeButton.upState = this.retinoscopeButton.downState;
retinoscopeButtonState = 'down';
} else if (retinoscopeButtonState == 'down'){
this.retinoscopeButton.downState = this.retinoscopeButton.upState;
retinoscopeButtonState = 'up';
}
}
This works for me...
Note that this is using a MovieClip with three keyframes for the different 'states' in the button MC retinoscopeButton
var toggle;
if (!root.retinoscopeButton.hasEventListener("click")) {
toggle = false;
root.retinoscopeButton.addEventListener("click", retinoscopeButtonClickHandler.bind(this));
}
root.retinoscopeButton.addEventListener("mouseover", retinoscopeButtonRollOverHandler.bind(this));
root.retinoscopeButton.addEventListener("mouseout", retinoscopeButtonRollOutHandler.bind(this));
function retinoscopeButtonClickHandler() {
if (toggle == false) {
root.retinoscopeButton.gotoAndStop(2);
toggle = true;
} else if (toggle == true) {
root.retinoscopeButton.gotoAndStop(0);
toggle = false
}
}
function retinoscopeButtonRollOverHandler() {
if (toggle == false) {
root.retinoscopeButton.gotoAndStop(1);
}
}
function retinoscopeButtonRollOutHandler() {
if (toggle == false) {
root.retinoscopeButton.gotoAndStop(0);
}
}
I want that when click in "OK" in the confirm box the entire webpage go to fullscreen, but with this only get error TypeError: docelem.requestFullscreen is not a function. I tried of all but nothing...
var conf = confirm("Fullscreen mode?");
var docelem = document.documentElement;
if (conf == true) {
docelem.requestFullscreen();
}
else if (conf == true) {
docelem.mozRequestFullScreen();
}
else if (conf == true) {
docelem.webkitRequestFullScreen();
}
else if (conf == true) {
docelem.msRequestFullscreen();
}
Some solution? or is it not possible with confirm()? Because with a button works:
(function () {
var fullscreenon = document.getElementById("fullscreenbutton");//button Id
if (fullscreenon) {
fullscreenon.addEventListener("click", function () {
var docelem = document.documentElement;
if (docelem.requestFullscreen) {
docelem.requestFullscreen();
}
else if (docelem.msRequestFullscreen) {
docelem.msRequestFullscreen();
}
else if (docelem.mozRequestFullScreen) {
docelem.mozRequestFullScreen();
}
else if (docelem.webkitRequestFullScreen) {
docelem.webkitRequestFullScreen();
}
}, false);
}
})();
Firsty, your conditions are different between 2 samples. Right code is:
var conf = confirm("Fullscreen mode?");
var docelem = document.documentElement;
if (conf == true) {
if (docelem.requestFullscreen) {
docelem.requestFullscreen();
}
else if (docelem.mozRequestFullScreen) {
docelem.mozRequestFullScreen();
}
else if (docelem.webkitRequestFullscreen) {
docelem.webkitRequestFullscreen();
}
else if (docelem.msRequestFullscreen) {
docelem.msRequestFullscreen();
}
}
Secondly and importantly, you can't make fullscreen your page without a user interaction. This is a security restriction. If you trigger code above by a user click, it'll be work. For example:
document.onclick = function (argument) {
var conf = confirm("Fullscreen mode?");
var docelem = document.documentElement;
if (conf == true) {
if (docelem.requestFullscreen) {
docelem.requestFullscreen();
}
else if (docelem.mozRequestFullScreen) {
docelem.mozRequestFullScreen();
}
else if (docelem.webkitRequestFullScreen) {
docelem.webkitRequestFullScreen();
}
else if (docelem.msRequestFullscreen) {
docelem.msRequestFullscreen();
}
}
}
If you click anywhere on the page, fullscreen mode will be activated. More detail: https://stackoverflow.com/a/20533579/198062
I'm making a register page using HTML, CSS and JS and Java servlet etc. I have a monitorer() function which checks if the user has finished inputting everything before making the register button visible. But now everything works, but somewhere am getting screwed over and the button never comes back..
my button in reg.html :
<input type="submit" value="Register" class="btnSub" id="btnReg" style="visibility:hidden;"/>
javascript function monitorer()
function monitorer() {
var btnReg = document.getElementById("btnReg");
btnReg.style.visibility = "hidden";
var flag = true;
if (document.getElementById("fname").value.length >= 3) {
if (document.getElementById("lname").value.length >= 3) {
if (valiDate(document.getElementById("dob"))) {
if (document.getElementById("USN").value.length == 10) {
if (document.getElementById("passw").value.length > 5) {
var ticks = document.getElementsByClassName("checker"), i = 0;
for (i = 0; i < ticks.length; i++) {
if (ticks.item(i).innerHTML == "✔") {
alert("i val = " + i);
continue;
} else {
flag = false;
break;
}
}
}
} else {
flag = false;
document.getElementById("USN").focus();
}
} else {
flag = false;
document.getElementById("dob").focus();
}
} else {
flag = false;
document.getElementById("lname").focus();
}
} else {
flag = false;
document.getElementById("fname").focus();
}
if (flag == true) {
btnReg.style.visibility = "visible";
} else if(flag == false) {
btnReg.style.visibility = "hidden";
}}
And to help you get as good a picture as you can, a screenshot
See - all the ticks are there, the first name, last name etc are having value.length >=3 but still the register button doesn't show..
Also, I have put the monitorer() method in every input's "onBlur", "onChange" events.
Here is a link to my html file >>> reg.html
and please let me know if i can improve anything?
I'm pretty new when it comes to getting my head around JS functions. Everything I've used before, I've tended to use as-is, but I've been trying to combine and modify a function to get a Div to toggle (height & opacity) on a specific keypress. I have the first part (can get the div to show on a 'ctrl + o' combo), but can't combine it with an if statement to show or hide, based on current display status.
Current working 'show only' JS:
$(document).keydown(function (e) {
if (e.keyCode == 79 && e.ctrlKey) {
document.getElementById('thediv').style.height = 'auto';
document.getElementById('thediv').style.opacity = '1';
return false;
}
});
Not working 'toggle on/off' JS (I've tried changing this all over the place; this is more to give an idea of what I'm trying to achieve):
$(document).keydown(function (e) {
if (e.keyCode == 76 && e.ctrlKey) {
function toggler('thediv') {
var myDiv = document.getElementById('thediv').style.height;
if (myDiv == "auto") {
document.getElementById('thediv').style.height = "0px";
document.getElementById('thediv').style.opacity = "0";
} else {
document.getElementById('thediv').style.height = "auto";
document.getElementById('thediv').style.height = "1";
}
}
}
});
Any help would be really appreciated!
You want to show and hide an element, why set its height and visibility? Just show/hide it with toggle.
$(document).keydown(function (e) {
if (e.keyCode == 76 && e.ctrlKey) {
$("#thediv").toggle();
}
});
Looking at your code
$(document).keydown(function (e) {
if (e.keyCode == 76 && e.ctrlKey) {
//This funciton is never called, you define it, do not call it!
function toggler('thediv') { //<-- Error Here, you have a string as an argument?
var myDiv = document.getElementById('thediv').style.height;
if (myDiv == "auto") {
document.getElementById('thediv').style.height = "0px"; //<--Bad practice using document.getElementById('thediv') over and over. Store it into a variable and reference it.
document.getElementById('thediv').style.opacity = "0";
} else {
document.getElementById('thediv').style.height = "auto";
document.getElementById('thediv').style.height = "1";
}
}
}
});
I have a javascript page which checks an email and username, this works fine in every browser but Internet Explorer. The div box where errors are shown should be hidden unless an error is given e.g. username taken or invalid email.
If the email gets an error this is shown in the div tag, but doesnt work for username (in all browsers)
below is my code:
<script type="text/javascript">
var usernameok;
var emailok;
function checksubmit()
{
if (usernameok && emailok) {
document.getElementById("button").disabled = false;
} else {
document.getElementById("button").disabled = true;
}
}
function username(username)
{
make_request();
function stateck()
{
if (httpxml.readyState == 4) {
if (httpxml.responseText.indexOf("Username Ok") >= 0) {
usernameok = true;
} else {
usernameok = false;
}
checkCanSubmit();
}
}
httpxml.onreadystatechange = stateck;
user_url = "check_username.php?username=" + username.value;
httpxml.open("GET", user_url, true);
httpxml.send(null);
}
function email(email)
{
make_request();
function stateck()
{
if (httpxml.readyState == 4) {
if (httpxml.responseText.indexOf("Email Ok") >= 0) {
emailok = true;
} else {
emailok = false;
}
checkCanSubmit();
}
}
httpxml.onreadystatechange = stateck;
email_url = "check_email.php?email=" + email.value;
httpxml.open("GET", email_url, true);
httpxml.send(null);
}
</script>
I see your function stateck() is the return function from the HTTP request. However, you are defining it within another function. Not as an anonymous function, but just as a function within another function.
I see what you're doing now...ok, try this instead:
httpxml.onreadystatechange = function()
{
if (httpxml.readyState == 4) {
if (httpxml.responseText.indexOf("Email Ok") >= 0) {
document.getElementById("email").style.backgroundColor = "green";
document.getElementById("email").style.color = "white";
document.getElementById("email_div").style.display = 'none';
emailok = true;
} else {
document.getElementById("email").style.backgroundColor = "red";
document.getElementById("email_div").innerHTML=httpxml.responseText;
emailok = false;
}
checkCanSubmit();
}
};
Do you need to set your initial state to display: none? I think IE may initialize the divs with a non-0 height whereas the divs may be technically visible in other browsers but too short to see.
Edit:
Okay I think I misunderstood your question. Your problem is not with hiding the divs but with displaying errors for the username.
Nothing obvious jumps out at me. Try stepping through the code using VS or VWDE:
