JavaScript - Onkeyup Won't Work, But Onkeydown Will...
Just like the title says. What would make a block of code that runs an "onkeydown" work perfectly fine, but when changed to "onkeyup" it fails. I could post code, but I dont even think it would matter? onkeypress also fails.
Similar TutorialsI have client side scripting for a text box value which truncates value if user enters more than 255 characters. For this i use both onchange and onkeyUp events. I added Server side validation too(more cautious) to restrict user from continuing the page if he enters more than 255 chars. We are using this product from 7 yeras and yesterday one of the customer said that(he has a screenshot too) he saw the server side error message. this explains that my client side javascript methods doesnot fire. he is using IE browser. Any idea why this could happen?
I want to code a script that when you press the right arrow key, it goes to a page. any ideas? Hello All, This is my first post here, so hopefully I don't make to big an *** out of myself. Anyway, I am working on a small 2D game in javascript, and have character movement bound to the onkeydown event. The problem is, that there is a momentary delay between pressing the key, and then it realizing you are still holding it down. So it's Move->stop->Move smoothly You can see what I'm talking about here http://www.digitalswordsmen.com/at/townmap.cfm I know that the delay is happening at the operating system level (you see the same kind of delay if you open up notepad and hold down a letter key, first letter appears instantly, then a short delay before continuing). I was wondering if anyone has a possible solution though, or someway I could smooth out that delay. Also, the walking animations only seem to work in firefox. I guess IE doesn't play animated gifs while the onkeydown even is being fired. Not sure if there is a fix for that, other than animating the individual frames with JS, but that would be pretty laggy I think. Anyway, any input is appreciated. You can see all the code by of course just viewing source, its still fairly simple at this point. Thanks in advance. I was wondering if anyone could shed some light on this little problem. Code: function lostfocus(current,productNum,e)
{
var keycode;
if (window.event)
{
keycode = window.event.keyCode;
}
else if (e)
{
keycode = e.which;
}
if(keycode == 0)
{
if(current == ($("#itemCount"+productNum).val()-1))
{
newItem(productNum);
}
}
else
{
alert(keycode);
}
}
Works great in FireFox, but not in IE7 - it doesn't even get to the else alert statement. This is how it is called.. onkeypress='lostfocus($current,$productNum,event)' And that is inside of a input type=text element. And help would be greatly appreciated. This is an example piece of code which I wish to add to an onkeydown event: Code: function keyListen(param1,param2,e) {
// keycode for ie
if(window.event) {
e = window.event;
var keycode = e.keyCode;
}
// keycode for firefox, safari and opera
else {
var keycode = e.which;
}
// if right arrow key was pressed execute a function
if(keycode == '39') {
someFunction(param1,param2);
}
}
Then somewhere else in my code I dynamically add the function to an onkeydown event like so: Code: document.onkeydown = function() { keyListen(param1,param2,event) };
This works great in Internet Explorer, Opera, Safari and Google Chrome but not Firefox. Firefox keeps reporting that event is not defined, is there a way around this problem? I have also tried this: Code: document.onkeydown = function() { keyListen(param1,param2) };
I excluded the event, but still the same outcome, works well in all browsers apart from Firefox. Please help me, thankyou. I am trying to assign the left and right arrows, but I cannot get the code to work. It would be great to get some help--I am a newbie to coding. <html> <head> <script language="javascript" type="text/javascript"> document.onkeydown=function(e) { var thelink if (e.keyCode==37) thelink='prevlink' else if (e.keyCode==39) thelink='nextlink' else return document.location.href=document.getElementById(thelink).href} </script> </head> <body> <a href="#" onkeydown="return previous(this)" id="prevlink">PREVIOUS</a><br /> <br /> <a href="#" onkeydown="return next(this)" id="nextlink">NEXT</a> </body> </html> Hello everyone... I've got a question about an onKeyUp event. I'm using a text box that HAS to be a negative number therefore it has to have a - sign in front of the number. Can someone point me in the right direction as to how to write a function to do this? Thanks so much...
Hi, I have the following code. This code is working fine in FF but not in IE. Can any one let me know how i can resolve this. function handlerFunc (elem, elem1) //elem1 is id of input tag { elem.onKeyUp = keyupHandler (elem1); //throwing error in IE. If i remove argument it is working fine, but i want to make it work with arguments. } function keyUpHandler (elem1) { alert (elem1.form.name); } Now, i am adding a onKeyUp function to change the radio if the value of another field is larger than 1. But this code isn't working... Any thoughts? Code: function getUses() {
var listcost = document.getElementsByName('form[listcost]');
var uses = document.getElementById('Uses');
if (uses == 1) {
listcost[0].checked = true;
}
else {
listcost[1].checked = true;
}
}
Hey, I have a calculation system that uses ajax with php and xml and executes with onkeyup. The only problem with this is the result can be returned before the user finishes entering the entire number. My question is how can I give a delay prior to running the rest of the js. I know how to use setTimeout() but will it get reset out every time the function is called or for example if they enter 5 characters in the form, will the script be called 5 times with a second delay from each or will it only be called once? Is there a performance degradation involved? Hope that made sense. Thanks! <script type="text/javascript"> function sum1() { noofrow = document.getElementById("NoOfRow").value-0; for (i=1;i<=3;i++) { var DAY1=parseFloat(document.getElementById('"day"+i').value,2); var day2=parseFloat(document.getElementById("day"+i).value,2); var day3=parseFloat(document.getElementById("day"+i).value,2); var tot=DAY1+day2+day3; document.getElementById("day"+i).value=tot; } } </script> <?php mysql_connect("localhost", "Admin", "aaaaaa") or die(mysql_error()); mysql_select_db("sb") or die(mysql_error()); $sqlstr = "SELECT * FROM WWW "; $row=mysql_query($sqlstr); //echo $record; //$row = mysql_fetch_array( $record ); ?> <body> <table width="834" border="1"> <tr> <td width="115">Order name</td> <td width="80">qty</td> <td width="144">Day1</td> <td width="144">Day2</td> <td width="144">Day3</td> <td width="145">TOT</td> </tr> <?php $count=0; while($record = mysql_fetch_array( $row )) { $count++; ?> <tr> <td> <?php print $record['Ordername']; ?></td> <td> <?php print $record['QTY']; ?></td> <td><form id="form1" name="form1" method="post" action=""> <label> <input type="text" name="day1qty<?php echo $count ?>" value="" /> </label> </form> </td> <td> <label> <input type="text" name="day1qty<?php echo $count ?>" /> </label> </td> <td> <label> <input type="text" name="day2qty<?php echo $count ?>" /> </label> </td> <td> <label> <input type="text" name="ttl<?php echo $count ?>" onkeyup="sum1()" /> </label> <input name="NoOfRow" id="NoOfRow" type="hidden" size="4" value="<?php echo $count ?>"> </form> </td> </tr> <?php echo $count; } ?> </table> please help me for the above code to get the sum of day1 day2 day3 onkeyup to get the total im really confusing above this plzz help me for to get the ttl value when key in values plzz help me ......................... give me smaple code also I have a function that checks to see the number entered in a textfield and then, if greater than 1, will change a radio button from Single to Multiple and visa versa. The function is called from the textfield with an onkeyup="function()". The problem I am having is that it works in IE just fine, but in Firefox it doesn't seem to be doing anything. I'm not getting any errors and can't seem to see what is the problem. Google doesn't seem to be any help... Anyone have any ideas? Thanks! what is the best way to count the seconds between each onkeyup to "autosave" without sending an ajax command after each key? id like my script to update after 2 seconds of no typing.... (yes, jquery is in use on the page) Code: function microtime (get_as_float) {
var now = new Date().getTime() / 1000;
var s = parseInt(now, 10);
return (get_as_float) ? now : (Math.round((now - s) * 1000) / 1000) + ' ' + s;
}
var lastKeyUp=0;
function saveChange(id,field,value){
thismicrotime=microtime(true);
if(lastKeyUp == 0 || (thismicrotime-lastKeyUp) >= 2000000){
$.get("saveChange.php",
{ 'field': field, 'value': value, 'id': id },
function(data){
lastKeyUp=thismicrotime;
},
'xml'
);
}
}
Code: <input type="text" name="field1" onkeyup="saveChange('2','field1',this.value);" />
i'd use onchange or onblur but that requires you to unfocus the field before it saves... Hi, I currently have some buttons representing letters and a textbox. When a button is clicked, its value is copied into the text box. I have an onkeyup event which means that every time a button is clicked, a function is called which searches some arrays using the current text box value. However, the problem I am currently having is that the onkeyup event which calls the function works if I type the value in using my computer keyboard, but not when using the buttons (even though the buttons enter values into the textbox). Does anyone have any suggestions on how I can make it so that when I press a button, the onkeyup event triggers and the function is called? Thanks. Hi there, I have an ajax search function. I have an input text field where I type in what I want to search for, but I would like the search to be delayed of a few miliseconds before the ajax search is called. How could I do that? The search field: Code: <input type="text" onkeyup="searchPlayer(this.value)"> The javascript function: Code: function searchPlayer(str)
{
here is my ajax search...
}
I tried different ways but I don't seem to be able to delay the searchPlayer function. Any help on that? Should I use setTimeout on the input field, or in my function or in another function? And how do I pass the 'this.value' to my searchPlayer function if using setTimeout? I am lost... Thanks in advance! Hi, I'm a little rusty on my javascript. I'm trying to use onKeyUp and onBlur to validate html table field text entry. I'm using Firefox in Windows XP, and Javascript is turned on. Mind taking a look to see why it's not working? Thanks! -Jason Code: <html>

Hi, i try to do that every char that i type in a input-type there will be a alert, but it doesnt do that, when the page loads it pop ups one time an alert and it doesnt pop up more alerts when i type something in the input-type Sorry for the bad english here is my code Code: <script type="text/javascript">

</script>
I'm working on a script to check password strength "onkeyup",so when the user enters a password after every character i call a function to check the passwords strength.I'm almost ready,but i stucked with one thing: I want to check the same characters in the password,so i can deduct some point from the score if there are identical characters. Here is my code: PHP Code: var multis = 0; for(var x = 1; x < passLength; x++) { actChar = new RegExp(password.charAt(x),"g"); multis += password.match(actChar).length; } I know it seems an easy task,but i've spent at least 6 hours with it,(the first pitfall was that i didn't know the RegExp function and took my variables into the match() function,i think you can imagine the results)and i just can't figure this out,i always get crazy results,i've tried a few more versions as well without any luck. Thx in advance for anybody who can help me! I'm trying to output something in a separate div if the information entered in the form is invalid. It is simply not working, no errors. Code: <script type="text/javascript" language="javascript">
function validateIGN(ign) {
var validign = /^[a-zA-Z0-9]{1,30}$/;
if (!validign.test(ign)) {
document.getElementById.ignErrors.innerHTML = "<p>Your IGN is not formatted properly.";
}
else {
}
}
</script>
Heres the HTML where the onkeyup is.. Code: <form name= "newsletter" class="newsletter" action="doNewsletter.php" method="post">
<h2>Fill out this form if you want to be notified when the website is up!</h2><br/>
<center><table class="twoslot">
<tr>
<td>IGN(In Game Name):</td><td><input type="text" name="ign" onkeyup="return validateIGN(newsletter.ign.value);" /></td>
</tr>
<br/>
<tr>
<td>E-mail:</td><td><input type="text" name="email" /></td>
</tr>
<br/>
<tr>
<td>
<center>
<input type="submit" value="Submit" />
</center>
</td>
</tr>
</table></center>
<span style="font-size: .5em;">This is not working yet</span>
</form>
Input from Chromes on-screen keyboard and a form text field with an onchange or onkeyup function call doesn't seem to work. Can you think of a way around it? Cheers
