javascript function didn't work in chrome - javascript

i have this function witch shows the user a loadingpanel at postback.
It works fine in IE and Firefox.
But Chrome showed me this Error:
I don't understand why. Does anyone have an idea?
I mean why it works in IE and Firefox. Where is the difference that it doesn't work in Chrome?

I call it like this:

Your function lp is not defined in the else scope.
Try
var circle = new this.lp({

var circle = new lp({

Two signature pads in one form

I want to implement two signature pads in ONE form. One signature is for the applicant and the other one is for the evaluator.
The first pad works but the second pad is unresponsive. I am using JavaScript for the signature pads but it only works for the first pad. The signature will be saved to the database when the submit button is clicked. That is why id="save-signature-btn" is together with the code for the 'Submit' button.

In your javascript code you are working only with
canvas = document.getElementById('signature-canvas')
So that is the problem.
You should add a class on both signature canvases in html code for example signature like this:
<canvas id="signature-canvas" class="signature" style="width:375px;height:150px;max-width:100%;border:8px #CCC solid;background-color: white;"></canvas>
<canvas id="signature-canvas2" class="signature" style="width:375px;height:150px;max-width:100%;border:8px #CCC solid;background-color: white;"></canvas>
And then in javascript add one more pair of commands for second signature pad for control buttons (submit and reset) for second canvas.

Javascript, How to stop or pause the setInterval timer in this code?

I have a code for a slideshow that runs automatically and all I want is to stop the timer when I click on the image and pause it when i hover over it.
I tried the clearinterval function but it didn't work at all, so I need your help please.
This is the JavaScript code:
var m3D = function() {

}
}()
And as you see, on line 90 I have the setInterval timer function and after it the onclick function where I need to "reset" the timer, and on line 270 the onmouseover function where I need to "pause" the timer.
So how to do this?
Try using a flag variable. Add var pauseSlideshow = false; somewhere at the top of the file, so it will be in the global scope. Change the m()function like so:
var m = function() {
if(!pauseSlideshow) {
/*
*
* all of the code already in m()
*
*/
} // make sure to add this additional curly brace
}
And then you need an onmouseover and an onmouseout function to toggle pauseSlideshow, like this:
s.img.onmouseover = function() {
pauseSlideshow = true;
};
s.img.onmouseout = function() {
pauseSlideshow = false;
};

Sometimes white background goes transparent on whole page

I wanted to use this kind of Photo Collage on my Website: Seamless Photo Collage by AutomaticImageMontage
so I downloaded it and pasted the code to my Website..
it works but sometimes when the page loads the white background goes transparent on the whole page transperent background
I'm using Parallax and Bootstrap, sometimes the parallax isn't working properly too.
I have tried to set the background to white in CSS but nothing.. sometimes it loads normally but sometimes goes transparent,
I have checked the console too but it showes only

Jquery stopped working

I'm developping this mobile app and I'm usint this (https://github.com/krisrak/appframework-templates/blob/master/template-CarouselViewApp.html) as a carousel to change through content on a page. http://jsfiddle.net/nafis56/qCkqb/
So for this I need to mess around in HTML, CSS and Jquery. Unfortonetly I'm still very green at javascript so I need your help. I changed an ID to a Class because I need to call it more than once in the same page. In the original template I refeered to, it comes as an ID. So I did this to change it:
Changed matching code on html to call it as a Class.
<div class="panel" title="Desiree Charms" id="desiree_charms" style="overflow: hidden;"
data-appbuilder-object="page">
<div class="carousel">
<div class="carousel_page">
<h2>Desiree Charms</h2>
<p><img src="images/desiree_charms.jpg" style="width: 85%; height: 85%; display: block; margin-left: auto; margin-right: auto "
data-appbuilder-object="image" class="" title="">
</p>
</div>
<div class="carousel_page">
<h2>Page Two</h2>
<p>Text and images for Page Two goes here. Swipe to go to the
next page.</p>
</div>
</div>
<div class="carousel_dots"></div>
</div>
also this on the html.
<script>
$.ui.autoLaunch = false;
$.ui.animateHeaders = false;
$(document).ready(function(){
$.ui.launch();
});
$.ui.ready(function(){
carouselSetup();
});
function carouselSetup(){
// set size of carousel
$(".carousel").width($(".carousel").closest(".panel").width());
$(".carousel").height($(".carousel").closest(".panel").height()-25);
var options={
vertical:false, // page up/down
horizontal:true, // page left/right
pagingDiv:"carousel_dots", // div to hold the dots for paging
pagingCssName:"carousel_paging", //classname for the paging dots
pagingCssNameSelected: "carousel_paging_selected", //classname for the selected page dots
wrap:true //Creates a continuous carousel
}
var carousel = $(".carousel").carousel(options);
}
Changed # to . on Css.
.carousel {
overflow:hidden;
margin:0 -10px;
}
.carousel_page {
overflow: auto;
-webkit-scrolling:touch;
padding:0 10px;
}
.carousel_dots {

margin-left: auto;
margin-right: auto;

Now, on the CSS file when I change .carousel_dots to #carousel_dots as it was originally. The carousel starts working. The problem is I need it as a class not an ID.
I'm pretty sure the problem is in the jquery, somewhere in there I need to set carousel_dots as a class and not an ID, but where?
Any help will be much apreciated, thanks.
jQuery is designed to trigger on HTML selectors, either elements, ID's or Class's. It's very common for it to trigger on ID's because, as you identified, they occur once and that isolates the action to that particular item.
I know that you changed the ID's to Class's because you want to use the CSS class multiple times. You can do this by using Class's. But, to maintain the jQuery logic, you should not change the ID's to Class's for that purpose. Use the ID's to synch with jQuery. Use Class's to control your CSS.
It's difficult to advise you regarding the case you displayed because you didn't identify the initial status and exactly how you changed it. If you can do that, we can be specific about what changes you should make. Good luck.
