well, this seems to be a silly question but is getting on my nerves -.-
i am working with Javascript and Jquery,
i have a password <input> tag which is not nested in a form, i want to check wether the input matches a constant defined by me when typed by user and length = 4
here goes my current code :
<div id="pin">
PIN:<input id="pinin" type="password" value="" onchange="showValue(this);" size="5" name="password" maxlength="4"></input>
<button value="Validate" name="Validate" onclick="javascript:check()">Validate</button><br />
<a href="publ.html" title="Public Page">I dont know PIN, go to Public Page >></a><br />
</div>
i had to add " to div, else it would just show "pin"

Which part of it is gettng on your nerves?
You already have tied 'check()' javascript method on button click.
function check()
{
}
BTW: Why have you defined 'onchange="showValue(this);' for password field? It doesn't make sense here based on other control validating it.

|

it is not for validating, it is for checking if the code entered is same as that defined by me on a file located in ../public_html/
so that it cannot be accessed and value is called when Jsp needs it using <?php echo fopen... ?>
the part getting on my nerve is, the event does not fire onchange (when i type) but when i close the tab with data in it, it suddenly pops up with the correct answer if it is alert($('#pinin').val()));
what i want is when the len of pinin reaches 4, it checks if its value is equal to my const. and if true display a alert or redirect.

Dude, onchange will only fire once the focus goes away from the textbox! If you need to check at the time of entering data then use 'onKeyUp' instead of onchange.

thank you mate, that did just the trick i was looking for.
Gosh W3C didnt mention that event for textbox, will remember this. Thanks again..
function check(obj) {
var pin1 = parseStr(obj.value);
if (pin1.length == 4) {
if (pin1 == "3924") {
<?php setcookie... ?>
window.alert('Welcome master, Redirecting you');
setTimeout(function() {
document.location ='main.php';
}, 2000);
} else {
<?php setcookie... ?>
window.alert('Invalid Pin, Rerouting to Public Page.');
setTimeout(function() {
document.location ='publ.php';
}, 2000);
}
}
}
Just in case you were wondering why i used master, This is still in development and i like being treated like a Master... xP

Hello,
Is there any kind of event that I can hook into that will indicate whether or not the print-dialog window of adobe's browser plug-in has gone away. If they clicked print I want to close the window but can't find away to get an indicator that this action has been done.
Thank you.

Hi,
I have a DIV tag that I want to hide the content when the webpage loads and you can click a link to show the content in the tag or hide it. What I am wanting to do is have one link that says "show" before you click it and when you click it, shows the content of the DIV and the text changes to "hide" and when you click "hide" the DIV content hides and the text reverts to saying "show" and when you click it, it shows the DIV content and so on.
Code in header:
<script language=javascript type='text/javascript'>
function hideDiv() {
if (document.getElementById) {
document.getElementById('hideshow').style.visibility = 'hidden';
}
else {
if (document.layers) {
document.hideshow.visibility = 'hidden';
}
else {
document.all.hideshow.style.visibility = 'hidden';
}
}
}
function showDiv() {
if (document.getElementById) {
document.getElementById('hideshow').style.visibility = 'visible';
}
else {
if (document.layers) {
document.hideshow.visibility = 'visible';
}
else {
document.all.hideshow.style.visibility = 'visible';
}
}
}
</script>
the DIV tag where the content is placed in is this:
<div id="hideshow" class="style111">;
Content here
</div>
I have this code to show and hide the div tag:
<a onclick="javascript:showDiv()"</a class="style110"> show</a><a onclick="javascript:hideDiv()" class="style110">hide</a>
Is there a way of using one link to show and hide the div tag rather than two seperate links? And is there a way of automatically hide the content when the page loads so you have to click "show" to show the content?
Thanks in advance
In the end we're all just the same

Look at JQuery, particularly the toggle[^] method.
JQuery is also cross-browser compatible so you won't need the all of the tedious, error prone code above to support multiple browsers.

Personally, I would forget about Netscape users. Anypme that still uses Netscape 4 gets what they deserve.... And while JQuery is good, it won't help you understand anything, and IMHO is a bit like using a sledgehammer to crack a nut, in this scenario anyway.
The following will work in most browsers - you won't get too many complaints. NB, you don't, of course, need to pass the element ID's as variables to the toggle function, but could hard-code them within - but doing so makes it more generic for use elsewhere, or with more than one such show/hide link on the same page.
<html>
<head>
<title></title>
<script language="javascript">
function toggleDiv(d, h) {
var div = document.getElementById(d);
var lnk = document.getElementById(h);
if (div.style.display == 'none') {
div.style.display = 'inline';
lnk.innerHTML = 'Hide';
} else {
div.style.display = 'none';
lnk.innerHTML = 'Show';
}
}
</script>
</head>
<body>
<form id="form1" >
<div><p><a href="#" id="lnk" onclick="toggleDiv('fred','lnk')">Show</a></p></div>
<div id="fred" style="display:none;">Now you see me</div>
</form>
</body>
</html>

Hi All,

If you can't make any changes then how are you going to do anything?
The first thing would be to redesign and not use popups. Otherwise you'll need to keep track of windows that are opened and close them during log out or on the close event of the main window

Hi Mark,
Thanks for reply. I mean of not change existing modules means I can not change each and every program which is opening the pop-up. I can change some of main programs. Can you please give me soluation for this?
Thanks a lot once again.
Thanks,
RK..

There is no solution if you don't have control over the apps that are opening the windows

IS there any way to find out the URL of all opened browsers? Please reply.
Thanks a lot.

If you are opening the popup using a common function, then only you can track the windows and close all the popup windows if user clicks on logout.

Hi,
Greetings everyone!
In my web application in a certain form, I want to show help text for some of the labels. The codes are as following:
<dt style="position:relative;">Pathway<a href="#"><img src="Images/1280835207_information-balloon.png" alt="" border="=0" id="show" onmouseover="showDiv('show');" onmouseout="hideDiv('show','wrapper');" /></a>
<div id="wrapper" style="width:275px; position:absolute; left:180px; " >
<div style="background:url(Images/div_head.png) no-repeat ; width:275px; height:60px;"></div>
<div style="background:#d8d7d3; width:263px; padding:4px; border-left:2px solid #f39716;border-right:2px solid #f39716">hjgfdhfhhh hhhhhhh hhhhhhhh ghhghgj jhjuvhfgf hjfkdg hkijdkf hgtjnglk.</div>
<div style="background:url(Images/div_bot.png) no-repeat; width:275px; height:19px;">
</div>
</div>
</dt>
And the javascript is as follows :
<script type="text/javascript">
function hideDiv(sh,wr)
{
document.getElementById(sh).style.display = '';
document.getElementById(wr).style.display = 'none';
}
function showDiv(wr)
{
document.getElementById(wr).style.display = '';
}
</script>
The problem is that this help text will be shown for some more labels in the same page. You can see that I'm maintaining the position of the help-text div by maintaining it's left position :
position:absolute; left:50px;
So when the label-text is larger then this position will not be applied. Is there a way to dynamically maintain the left position? I mean to say for larger or smaller label-text the position of the help-div will be adjusted automatically. I'm not sure whether I'm successful in making my need clear. Can anyone please help me?
Thanks in advance.

Pass image object refrence in showdiv fn
onmouseover="showDiv(this,'wrapper');"
And set the left position dynamically
function showDiv(obj,wr) {
document.getElementById(wr).style.left = obj.offsetLeft + 'px';
document.getElementById(wr).style.display = '';
}

You can not access client file, unless you use Activex and give special permission. Just think what could happen if javascript are allowed to access client files.
