If I click this button several times and leave the page (google search) then hit back on my browser
1) Chrome resets the DOM so it looks like the page has been refreshed
2) Firefox keeps the DOM but F5 will put it back to its initial state as expected
I'd like the firefox behavior in chrome. Is there a way to do that?

I think you can type
about:config
in the adress bar and search for
"browser.cache.check_doc_frequency"
and change it to 1 , that means it reloads every time

I have following HTML,
$(document).ready(function() {
$('#searchMovieBtn').click(function(e) {
e.preventDefault();
console.log('search');
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="searchMovieBtnBox">
<button class="btn btn-primary" type="button" id="searchMovieBtn">Search</button>
</div>
When I click on button, nothing happens, it seems like event is not triggering.
It is a caching issue. When you was developing and testing your JQuery code, your old code remained into the browser cache. Browser cached it to load page faster in next uses. In order to solve this problem you have 3 options.
Delete your browser history
Refresh your browser by pressing Ctrl + F5 (Preferred for developing purpose)
Tell browser that this JQuery code has changed by adding a version for it. It is used when you are publishing your code on the server because you can't ask your clients to delete their browser history or load your page by pressing Ctrl + F5
Here is how you could add version to your JQuery code:
<script type="text/javascript" src="js/script.js?v=1"></script>
Look at v=1. Next time when you updated your JQuery code change it to v=2 to tell browser that your code has been changed.
You can try the next thing,
First of all, your HTML markup I think it might be wrong as you are not pointing out correctly the folders.
I attached all the css and js bootstrap + jquery files through a CDN.

Therefore,your script.js stays as it is.
For me it has worked like this. I got the message printed onto my console.
Hope that helps you.
Make sure you don't have another element in the HTML with the same id.
I'm trying to create a simple proof-of-concept regarding the use of localStorage to trigger tabs in my application when changes occur. I know this is possible based on other articles I've seen. I understand the spec states the event will fire on ever page except the one I'm on - this is in fact what I want. However, I can't seem to get this simple demo to actually work.
I've taken the code below, and opened up multiple tabs of it. Using my Chrome Dev Tools, I can check >localStorage in the console and see the value before and after the "Add" and "Clear" buttons are pressed - they are in fact functioning as desired in storing and clearing the key value pair into local storage, yet the event isn't firing the alert.
I even placed breakpoints in the javascript in my Chrome Dev Tools of each tab, yet I can never seem to get the "onStorageEvent" function to hit in any tab opened.
What am I doing wrong?
<!DOCTYPE html>
<html>
<head>
<title>Tab1</title>
</head>
<body>
<button id="add" onclick="localStorage.setItem('tab','changed')">Add</button>
<button id="clear" onclick="localStorage.clear()">Clear</button>
<script type="text/javascript">
function onStorageEvent() {
alert("storage event: " + localStorage.getItem("tab"));
}
window.addEventListener('storage', onStorageEvent, false);
</script>
</body>
</html>
In order for the window.addEventListener to work on storage:
you MUST access the page using web-server (http://a.b.c.d/ or http://domain)
Direct access (using file:/// or c:\file.html will not work.
(chrome and ie ignore it, firefox and safari can run it anyway).
I would consider also removing the 3rd, it is not relevant to elements in your DOM tree, and it might cause troubles (let the browser have it's defaults).
This code was tested in Chrome 52, Firefox 47+48, IE 11, Safari 5.7.1
<!DOCTYPE html>
<html>
<head>
<title>Tab1</title>
</head>
<body>
<button id="add" onclick="localStorage.setItem('tab','changed')">Add</button>
<button id="clear" onclick="localStorage.clear()">Clear</button>
<script type="text/javascript">
function onStorageEvent() {
alert("storage event: " + localStorage.getItem("tab"));
}
window.addEventListener('storage', onStorageEvent);
</script>

I am working on a legacy app that has an iframe involved. The back button is working on the iframe and I need it to bypass the iframe and work on the parent window only.
Here is a dumbed down version of the issue and description of what I know.
the main page "index.html" has an iframe that is being added via javascript. It loads a.html, makes an ajax call that then does a window.location = "b.html" At this point if you use the back button it essentiallys makes the iframe go back to a.html and then redirects to b.html so you are effectively stuck on the page. If I remove the ajax call and do an window.location on load everything works ok. However given the architecture and what happen on the page I can't remove the Ajax call from the picture.
Here is the code I am looking at, let me know your thoughts on how to solve this issue. Also I should mention in Chrome 41 this isn't an issue, however the newer chrome 48 and 49 it is an issue. I tried history.replaceState but wasn't able to figure out a way to use it in this situation that made things work.

This is only possible in HTML5 compatible browsers, and it would go something like this..
This goes in the child frame..
// catch the back button click.
window.onpopstate = function(event) {
// make the parent window go back
top.history.back();
};
This also only works if both frames are in teh same domain.
I have a button Which prints the Page on click of a button which triggers onclick(); javascript function. the code goes like this.
<html>
<input type="submit" value="Print" onclick="printInfo()">
</html>
Script is placed in <head> tag
<script type="text/javascript">
function printInfo()
{
window.print();
}
</script>
when we click on the button in Chrome and Mozilla the page is printed normally but in IE the font decreases and is set to half of the page.
Please help me on how to maintain consistent in IE and Chrome.
I have an open web page dialog. From there, what I'd like to do is when the user clicks on a link, refresh the contents of the dialog with modified query string parameters. The problem I am running into is that rather than refresh the same web page with new parameters, a new browser window pops up.
Here is the page used to open the dialog:
<!DOCTYPE html>
<html>
<head>
<title></title>
<script type="text/javascript">
function ShowPopup() {
var popWinFeatures = "dialogWidth: 800px;dialogHeight:600px;center:yes;status:no;scroll:no;resizable:yes;help:no";
window.showModalDialog("webPageDialog.html","PopUpWin",popWinFeatures);
}
</script>
</head>
<body>
Click For Modal
</body>
</html>
and this is the code within the webpage dialog that attempts to refresh the webpage with changed query string parameters:
<!DOCTYPE html>
<html>
<head>
<title></title>
<script src="scripts/jquery-1.6.4.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
var queryString = "?ab=123";
var newURL = window.location.protocol + "//" + window.location.host + "/" + window.location.pathname;
$('#testLink').attr('href', newURL+queryString);
});
</script>
</head>
<body>
Please Click Me
</body>
</html>
I've also tried using window.open as well as setting window.location. And I've also tried setting window.location.href but the result was the same.
the new browser window displays exactly what I expect. It's just not in the same window.
Thoughts?
Since posting this question, I came up with two possible solutions. In case anyone comes after me and wants to know what I ended up doing, here you go!
The first was just to make the popup non-modal. Removing the modal piece gave me the behavior exactly like I expected it. This didn't work in my situation however for a different reason... It seems that the session cookie was not carried over which in this web app, would cause the log-in page to be displayed before then displaying the correct page. This struck me as odd, but ran out of time to investigate why that was happening.
Second (and this is the solution i ended up going with) was to use an iframe, and display what i needed within the iframe. Definitely not my favorite, but it works!
