If I try the code below on the console in Chrome, it is working. But the code is not working in my Javascript extension in Chrome.
var region = document.getElementById("physicalDeliveryOfficeName");
region.removeAttribute("onchange");
Any thoughts what am I doing wrong? Tried to add this line in my function and on the top of my script but it is not working.
This is due to the execution environment that it is isolated in a Chrome extension.
You have to inject the code into the page to do modify the page context handlers.
Please see Insert code into the page context using a content script
It works in console because the dom has loaded. Wrap your code in an event handler.
document.addEventListener("DOMContentLoaded", function(event) {
var region = document.getElementById("physicalDeliveryOfficeName");
region.removeAttribute("onchange");
});

I'm trying to inject code into YouTube that fixes a bug in Magic Actions for YouTube. I have the following code from Magic Actions for Youtube that fixes the placement of Action bar that comes under the video but after update to YouTube it shows up at the top.
javascript:(function(){var b=document.querySelector('#watch7-content span'),a=document.querySelector('ytd-video-primary-info-renderer'),c=a&&a.firstElementChild;b&&a&&c&&a.insertBefore(b,c)})();
The above code is used as a bookmark but I want to use Tampermonkey to insert and run this code anytime the YouTube video plays.
window.onload = function() {
var b=document.querySelector('#watch7-content span'),a=document.querySelector('ytd-video-primary-info-renderer'),c=a&&a.firstElementChild;b&&a&&c&&a.insertBefore(b,c);
};

I have a slight problem with this online code editor. When I launch my snippet, it only works one time. If I try to bring any modification to the code, it crashes for unknown reasons.
https://playcode.io/313059?tabs=console&script.js&output
Any clue of what is going on here?
I just checked and I think that your code is executing while the editor is not loaded yet. Wait for the document or window to be loaded and then execute the code as following:
$( document ).ready(function() {
var block = document.getElementById('block');
var block_scale = window
.getComputedStyle(block, null)
.getPropertyValue("transform");
var matrix = block_scale.match(/\d+(?:\.\d+)?/gm);
console.log(matrix[0]);
});

Adding this line of code $("#locate-me-button").click(loadLocation()); breaks my entire JavaScript code file even if I don't click the #locate-me-button element. When this line is commented out the entire file works perfectly again. Why would that be?
You are invoking the function as passing its return value to event handler, just pass the function reference to .click()
$("#locate-me-button").click(loadLocation);
//^ () is removed
The another way (at least for case that you have parameter):
$("#locate-me-button").click(function(){
loadLocation();
});

This is the image of my html code.
I want to get rid of the line boxed in red.Please help me.That line does not show in the actual code, but when the page is opened on a browser i.e in (google chrome) and selected "view source code" it shows the line.I want to get rid of it.Please help me, reply me a.s.a.p..Thank you.
Definitely adware. Check out: http://www.malwarekillers.com/tag/remove-track-breaking-news/
As #Tanuel said, this is either from malware or a browser extension since it seems that you didn't put it in the source code.
Go to Dev Tools in Chrome (Ctrl+Shift+i) and look at Network and check what scripts are being loaded on the page.
Also, take your time to explore the Elements tab and to find out how that line is being added to the code.
This is a bad post but I can feel the frustration in your question and the answer is probably just this:
<script>
$(document).on('pageload',function()
{
document.getElementsByTagName('script')[0]='';
});
</script>
Add it to the bottom of your page.

I have wrote following code example:
html:
<input type="checkbox" name="terminal" class="all" data-terminal-id="9800" >
javascript:
function checkRightBarVisibility(){
if(this.checked){
alert('checked');
}
}
$('input[name=terminal]').change(checkRightBarVisibility);
http://jsfiddle.net/o9ovnkxv/6/
This code works as expected.
But in my real code I have same javascipt code but I don't see alert.
I have not ideas how can it possible.
debug information:
bigger picture(http://i.stack.imgur.com/ADXB5.jpg)
Please help me to find the mistake.
P.S.
full code is very huge thus I didn't post it.
update:
I tried following in debug:
I wrote following row:
$('input[name=terminal]').change(checkRightBarVisibility);
After it I have seen alert 1 time.
But only one time.
If your inputs are being added dynamically then you should use delegation:
$('body').on("change", 'input[name=terminal]', checkRightBarVisibility);
(In jQuery, how to attach events to dynamic html elements?)
