I need to build a chart with the Chart.js library.
I've got a strange behavior with Firefox: the charts behaves randomly, sometimes it's OK and sometimes I need to click several times on my button.
Does anyone know of a method in JavaScript to force the reload via a simple button like this?:
Refresh the page
To see the other ways to reload the page you can check this comment https://stackoverflow.com/a/7632005/17542117, but most likely browser should be reloading with your code snippet itself.
If you are still facing the issue try the following things,
try to narrow down the places where you have to click multiple times
check if you see an invisible overlay over the button which could be blocking your click action. (try placing the button from the top to the bottom of the screen while scrolling and try clicking it at multiple positions, this might help you too to find if invisible overlay is only in a specific portion of the screen)
try to see if your click function throws any console errors which can block your JS code execution on the click action.

The search icon on my mobile website suddenly stopped working recently. It's supposed to toggle open a search bar; however, now when I click it, nothing happens.
When I long press via Chrome on mobile it displays "about:blank#blocked" and on Firefox on hover it displays javascript:void(0).
Not sure what caused it to stop working and it's a bit frustrating.
If anyone has any insights or ideas on how to solve it, that would be super helpful.

I see your issue:-
Your issue is when you are trying to access custom search form that unable to access because you added an extra search button which is not belongs to that. So you try toggle function to show yellow colored area of your code. After it your issue will solve. Below I have attached your site screenshot image, that you can see it for the reference.
I am trying to make a page COMPLETELY UNCLICKABLE (both right click and left click) and to display a message when someone clicks. Since I know that this will raise lots of questions such as
"why would anyone ever want to do this...this is stupid...then nobody
can navigate the site...and it doesn't protect your content
anyway...etc"
here is the explanation of my purpose. I have a page that is at the moment only a graphic mockup of what the finished website will eventually look like. No matter how many times I explain that the mockup is ONLY AN IMAGE and not a real navigable website, they still email me to say that they cannot click on the menus and links. Since it is a single page mockup, I want to pop up an alert() message (can't use a modal because you can't click to dismiss it if clicking is disabled) to let them know that they have clicked something non-functional. I am trying to do this in as few lines of code as possible, and have the following working at the moment:
<script>
$('html').mousedown(function(event) {
event.preventDefault();//To prevent following the link
alert('Demo Graphic Only...clicking on stuff will NOT work at this point.');
});
</script>
The issue is that when using .mousedown I capture the user trying to click on the browser scroll-bar to scroll down. I was surprised by this since it is not part of the actual PAGE CONTENT but rather a part of the BROWSER...but it is catching it nonetheless. I tried using .click in place of .mousedown however only seem to catch a normal (left) click in that case... Does anyone know how to easily (minimal lines of code if possible) capture the left AND right click event, but allow user interaction with the browser scrollbar?
Try this :
$(document).click(function(event) {
event.preventDefault();//To prevent following the link
console.log('Demo Graphic Only...clicking on stuff will NOT work at this point.');
});
This Function will be called when click is made on the page , not on the Scrollbars
Try to use
event.stopPropagation();
or
event.stopImmediatePropagation()
For people who come across this question, an alternative approach, good especially if you need to prevent mousedown specifically:
Put the scrolling content in a wrapper element and prevent mousedown only on the inner element. Set the wrapper element to overflow: auto; height: 100%;
I have an aspx page on my SharePoint site, which I have included tags. For some reason, every button on the page will reload the page when clicked. Even the buttons with no attributes (id, class, etc) or functions will reload the page when clicked. How can I fix this issue? I can't even see what's going on in the debugger because I'm not calling any reload functions, so I have no idea where to place a breakpoint.
Thank you in advance for your help, I really appreciate it.
The problem here is with the <button> tag. Its default behavior is to act as a submit button unless otherwise declared and will reload.
To keep your <button> tag, add type='button' to the button element. I think that prevents the reload.
Or you could go with the ole <input> tag with a type='button'. That keeps the reload from happening as well.
Or some other html element with an onclick event will work too.
First search for a function called doPostback and set a breakpoint on the entry point and click a button. If you hit this breakpoint it could mean that auto post back is turned on for the control generating the button. However if you trigger that breakpoint you should be able to look at the stack trace to figure out how you got there.
If that doesn't work, use the F12 tools in the browser, start with the HTML section and search (Ctrl-F) for the word "click". Then go to the script tab and do the same for each JavaScript file. If all of the buttons exhibit the behavior there is most likely a click event registered. Possibly with jQuery that looks like this $('button') so that it matches all buttons on the page and registers a click handler.
If that doesn't find it, and you have access download one of the master pages from http://startermasterpages.codeplex.com/ and temporarily replace your master page with one of these. Take a screenshot of the scripts that are loading on your page first. Then add them to the starter master page one at a time until the unwanted behavior returns. Then set a breakpoint on every function entry point in that script and click a button and see where you land.
I'm currently moving a website from self hosted onto a CMS system. The current site uses a modal popup script called SqueezeBox.js
I've copied the code across exactly how it looks on the current website, however the modal popup box isn't triggering when I click on a thumbnail image.
Looking at the code in the header I've spotted that the CMS I'm using is also calling a number of other javascript files and I'm wondering if one of them is causing a conflict.
What's the best way to find out if this is the case? I've tried Firefox's plugin Web Developer but can't see anything in the Error Console. However I'm not 100% sure I'm using it correctly. Can anyone else point me in the direction of a simple to use javascript conflict detector?
Cheers

If you have Google Chrome, open up the Developer Tools and you can go into the 'scripts' tab, open up your javascript files and look for the click handler.. click along the side of the code to set a breakpoint, then when the code reaches that spot (if you click it, for example), it will pause, and then in the Developer Tools you can see what functions are being called where as you step through the code. You can also hover over any variable in the code window to see its value. Very handy! You can then see if it's getting into your plugin at all (you can do this as well by setting a breakpoint inside the plugin at a place like the first line that will always be accessed when its run).
I believe you can do the same thing with Firebug
It's a bit of a different thinking process to get into (step into, step over, turning breakpoints on and off etc) but it's extremely useful.
A more simple way of checking where problems are occuring is by adding an alert('im working); or something similar to code you're not sure if it's working. You can also alert a variable to see what the value is at that point. You can also use console command to print it to firebug's console. These are doing things that breakpoints/debugging do for you except with the debugging you don't need to change your code.
If there is a javascript error, then the easies way is using firebug or the Chrome Inspector (right click on the thumbnail and choose "Inspect element"). Open the console tab of either and refresh the page. If there is an error, it will be reported in the console and provide a link to the relevant line.
If there is no error being reported, then the code's logic is preventing the box from being displayed. You'll need to step through the code to find the error. Look at what function is being called from the click handler of the thumbnail image. Go to that function in either tool and place a breakpoint on the first line of the function. Click the thumbnail again and the code will pause on that line. From there you can step through the code and see which code branch is followed. There's likely a sanity check at some point that fails and causes the code to bomb out.
I have a page that uses JQuery UI Tabs and some other bits and pieces. When a user opens this page and quickly clicks on some tab, after a second or so the page reverts to the first tab again!
I am trying to use Firebug to see what's going on, but as far as I can see, when that reversion occurs the body tag highlights, but nothing within it. I am a novice with Firebug - how can I use it to better understand what's going on here?
I can only take a guess without a concrete example, but it sounds you're initialising the tabs twice. The tabs must already be enabled which is allowing the initial navigation between tabs. Then a second initialisation of the tabs is resetting the view back to the first tab.
You are initialising the tabs inside $(document).ready and not window.onload, right?
