Dialog appears on every refresh

I have to build a dialog in my entry site. The problem is, it appears every time and I can't close it (click on the button just refreshes the site, with the dialog appearing again). I also thing that I know the reason, but I'm able to fix it.
This is my dialog
<p:dialog id="ac-wrapper" widgetVar="test" style='display: none; background:white;' modal="true"
resizable="false" closeOnEscape="true" closable="true" visible="true">
<div id="popup">
<h2>Some Content</h2>
<input type="submit" name="submit" value="Submit"
onclick="DialogBox('hide')" />
</div>
</p:dialog>
Here is the javascript that should handle this:
<script type="text/javascript">
$ = jQuery;
function DialogBox(hideOrshow) {
if (hideOrshow == 'hide') {
localStorage.setItem("isShown",1);
document.getElementById('ac-wrapper').style.display = "none";
document.getElementById('ac-wrapper').visible="false";
$("#ac-wrapper").close();
}
else if(localStorage.getItem("isShown") == null) {
document.getElementById('ac-wrapper').removeAttribute('style');
localStorage.setItem("isShown",1);
}
}
window.onload = function () {
setTimeout(function () {
if(localStorage.getItem("isShown") != 1 ){
DialogBox('show');
}
else if(localStorage.getItem("isShown")){
$("#ac-wrapper").remove();
}}, 1000);
}
</script>
By rendering the site, the dialog always appeares because the visible attribute is set on "true". I guess the order is incorrect. It should frist check the local storage and then render the elements, I'm not getting it to work correctly. I also looked for answeres here with similar problems, but nothing helped.

The issue is this
<input type="submit" name="submit" value="Submit"
onclick="DialogBox('hide')" />
because its an input type submit, its defaulting to the form behavior... which is to redirect to the same url using GET. Change the type and value to "button" and "close" and your problem will be resolved

parsley.js does not work for ckeditor textarea

I wrote code for my form with parsley.js validator, however it works fine except CKEditor textareas. Where can be the problem? Here is screenshot
Here is my code:
<script type="text/javascript">
CKEDITOR.on('instanceReady', function(){
$.each( CKEDITOR.instances, function(instance) {
CKEDITOR.instances[instance].on("change",function(e) {
for ( instance in CKEDITOR.instances)
CKEDITOR.instances[instance].updateElement();
});
});
});
</script>
<h2 class="heading">Description</h2>
<div class="controls">
<textarea name="description" id="description" required="" data-parsley-errors-container="#description-errors" data-parsley-required-message="Это поле необходимо!"></textarea>
</div>
<div style="margin-bottom: 20px;" id="description-errors"></div>
<script>
CKEDITOR.replace('description');
</script>
<h2 class="heading">Purpose</h2>
<div class="controls">
<textarea name="purpose" id="purpose" required="" data-parsley-errors-container="#purpose-errors" data-parsley-required-message="Это поле необходимо!"></textarea>
<div style="margin-bottom: 20px;" id="purpose-errors"></div><br><br>
<button type="submit" name="submit">Submit</button>
</div>
<script>
CKEDITOR.replace('purpose');
</script>

Your issue is related to the required attribute. After, this line:
CKEDITOR.on('instanceReady', function () {
you need to add such an attribute again, for each text area, because lost during CKEDITOR init phase (i.e.: CKEDITOR.replace('purpose');).
For a specific textarea you can write:
$('#description').attr('required', '');
For all the textareas belonging to the form:
$('form textarea').attr('required', '');
From your comment:
When the error shows in other inputs and when I type something it removes automatically. But in textareas it does not leave
In order to solve this part, on CKEDITOR change event, you need to trigger parsley validation. The below line does the trick:
$('form').parsley().validate();
The updated code (jsfiddle here):
CKEDITOR.on('instanceReady', function () {
$('form textarea').attr('required', '');
$.each(CKEDITOR.instances, function (instance) {
CKEDITOR.instances[instance].on("change", function (e) {
for (instance in CKEDITOR.instances) {
CKEDITOR.instances[instance].updateElement();
$('form').parsley().validate();
}
});
});
});

It's always so much easier to answer questions if you provide a minimal working example...
ckeditor hides the <textarea> and fills it in via Javascript.
Maybe the issue is that the error container is in the wrong place.
It's also very possible that ckeditor doesn't trigger the input event (not very well known). If that's the case, the following code should resolve the issue:
$('textarea').on('change', function() { $(this).trigger('input') })
Please update if this works or not.

ERROR displaying image while form is processing

i need to display image when form is processing
And this following code works problem is when i press submit image is displayed but if there are some error in form filed the form will not process but images is displayed
How do i make images display when user press submit button the image should appear only when form is processing
CODE
<input onclick="showImg()" class="btn btn-success" type="submit" name="submit" value="Search"/>
<img alt="" src="ajax-loader.gif" id="progress_img" style="visibility:hidden;">
<script language="javascript" type="text/javascript">
function showImg()
{
if (document.getElementById) {
(document.getElementById("progress_img")).style.visibility = "visible";
}
}
</script>

Well I have created a small demo. Check it out.
var progressImg = document.getElementById('progress_img');
var myForm = document.getElementById('myForm');
myForm.onsubmit = onFormSubmit;
function onFormSubmit() {
var error = false;
// Check for errors
if (error) {
// Show error messages
} else {
// Display the image
progressImg.style.display = 'block';
// Do your AJAX call
// and hide the image when AJAX is completed
}
// This is to prevent the form from submitting
return false;
}
#progress_img {
width: 20px;
height: 20px;
display: none;
background: #aaa;
}
<form id="myForm" action="#">
<input class="btn btn-success" type="submit" name="submit" value="Search" />
<img id="progress_img" src="ajax-loader.gif" alt="">
</form>
If anything is not clear for you, feel free to ask me.

I don't think I fully undestood what you are trying to do, but you could validate all the things you need using javascript.
The best way to achieve what you are willing is to change the button type to "button", not "submit" and then on the "onClick" "showImg()" function, replace it for the validations, then show the image, and then use the javascript submit function. I know it's easy with
document.getElementById("myForm").submit();

Button onclick to hide text

I have a JavaScript where I need to hide (and eventually show) some text by clicking a button. However, when I click the button, it does not call the function specified in the onclick parameter, and so nothing happens. Here is my source code:
<script type="text/javascript">
$(document).ready(function(){
var tip = 1;
$(".tip1").hide();
$(".tip2").hide();
switch (tip) {
case 1:
$(".tip1").show();
break;
case 2:
$(".tip2").show();
break;
}
function nextTip() {
$(".tip1").hide();
return;
}
});
</script>
<br/>
<div id='bg_container' style='background-image: url("<?=$PICS?>trackingpage_middle.jpg")' >
<img style='z-index:-1;' width='737px' src='<?=$PICS?>trackingpage_top.jpg'>
<div id='main_container' >
<form>
<input type="button" onClick="nextTip()" value = "Next Tip" />
</form>
<div class="tip1">
...
and so on.

Have you tried moving the function nextTip() out of $(document).ready to the global scope?

Take the nextTip() out of the $(document).ready(function(){} portion.

Since It seems you are using jQuery why don't you add:
$('input[type="button"]').click(function(){ $(".tip1").hide();});
to your $(document).ready( ... ) code ?

I want to disable link button after clicking of it and other enable. toggle enable/ disable between both link buttons using javascript

I want to disable link button after clicking of it & other enable. toggle enable/ disable between both link buttons using javascript
<a id="a1" href="page1.aspx">One</a><a id="a2" href="page2.aspx">Two</a>

Simple, just add listeners to the onclick events on both links, that disable the link in question and enable the other one.
Something like
document.getElementById('a1').onclick = function() {
document.getElementById('a1').disabled = true;
document.getElementById('a2').disabled = false;
};
document.getElementById('a2').onclick = function() {
document.getElementById('a2').disabled = true;
document.getElementById('a1').disabled = false;
};
Of course if you're going to be extending this to multiple buttons then you could easily abstract the above out to registration methods, looping over arrays of buttons etc. (possibly those that implement a particular class rather than explicitly specifying the array).

The simplest way is to hide the link rather than to make it disabled.
You can use this code to hide the link after click on it.
Its tested code & it worked perfect for me. :-)
<script type="text/javascript">
onclick = function() {
var chk= document.getElementById('myElementId');
chk.style.display="none";
};
</script>

To disable a LINK rather than a BUTTON, the only thing you can do apart from hiding it is to set it not to go anywhere.
onclick="this.href='javascript: void(0)';"

Your question can have any one of the following 3 possible scenario. Choose whichever suites your problem.
Case1) A catch in your question is that since they are links pointing to page1.aspx and page2.aspx respectively once you click on a link a new page loads in the browser. So the effect you want to achieve doesn't really matter.
Case 2) If, you have both the links 'One' and 'Two' on each of aspx pages then you can as well hardcode the disabling of the link pointing to itself. (Or as well not have the link at all).
Case 3) If you have a frame to display the links 'One', 'Two' and you have a another frame to load content of both links then your question has a meaning disabling the other link. Here is the code for the same.
<html>
<a id="a1" href="javascript:void(0)" onclick="toggle(objA1,objA2,'page1.aspx')">One</a>
<a id="a2" href="javascript:void(0)" onclick="toggle(objA2,objA1,'page2.aspx')">Two</a>
<br><iframe id="ifrm" src=""></iframe>
<script>
var objA1 = document.getElementById('a1');
var objA2 = document.getElementById('a2');
// d=element to disable, e=element to enable
function toggle(d,e,link)
{
//if already disabled do nothing(don't follow url)
if(d.disabled) return;
//enable/disable
d.disabled = true;
d.style.cursor = 'default';
e.disabled = false;
e.style.cursor = 'hand';
//follow link
ifrm.src = link;
}
</script>
</html>

You can access and set the "disabled" attribute like this:
if(somebutton.disabled == true){
somebutton.disabled = false;
}
I recommend using a JavaScript framework like jQuery.

<html>
<head>
<script type="text/javascript" src="jquery-1.4.2.min.js"></script>
<style type="text/css">
.submit{
padding:8px;
border:1px solid blue;
}
</style>
</head>
<body>
<h1>Disabled submit form button after clicked with jQuery</h1>
<form action="#">
<p>
I'm a form ~
</p>
<input type="submit" value="Submit"></input>
<button>Enable Submit Button</button>
</form>
<script type="text/javascript">
$('input:submit').click(function(){
$('p').text("Form submiting.....").addClass('submit');
$('input:submit').attr("disabled", true);
});
$('button').click(function(){
$('p').text("I'm a form ~").removeClass('submit');
$('input:submit').attr("disabled", false);
});
</script>
</body>
</html>

<script type="text/javascript">
function validateForm(formObj) {
if (formObj.username.value=='') {
alert('Please enter a username');
return false;
}
formObj.submitButton.disabled = true;
formObj.submitButton.value = 'Please Wait...';
return true;
}
</script>
<form name="frmTest" action="" method="post" onsubmit="return validateForm(this);">
Username: <input type="text" name="username" value="" /><br />
<input type="submit" name="submitButton" value="Submit" />
</form> ​​​​​​
