I am using jquery and its related plugins in my site.
Since i use more js. for visiting each page in my site. all the js loads so site loading time increases.
How to use js libraries efficiently without loading js for each page visit.
UPDATE:
I am using
<!-- JQUERY-->

This much of js i am using in header section. once i am visiting each page all these loads again and again
The user doesn't have to load it each time, just be sure to set your cache headers correctly so the user caches the JavaScript files that are reused. For libraries specifically (since this is tagged jQuery), look at using a CDN - which will also have the cache headers I mention, as well as parallelizing the download since it's not on your own domain.
Also, you can use a Content delivery network (CDN) for libraries like jQuery etc. Google provides a bunch.
Additionally to the previous answer you should minify all javascript file together, optionally you can use gzip compression.

I'm wondering if the order of the javascript in a page will affect how things work? If yes, is there any problem on my way of arranging them?
<script src="vendor/jquery/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script src="vendor/bootstrap/js/bootstrap.bundle.min.js"></script>
<script src="vendor/jquery-easing/jquery.easing.min.js"></script>

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script>
Yes it makes a huge difference and you have made the mistake of including TWO versions of jQuery, bootstrap and datatables. You need to remove
<script src="vendor/jquery/jquery.min.js"></script>
<script src="vendor/datatables/jquery.dataTables.min.js"></script>
and
<script src="vendor/datatables/dataTables.bootstrap4.min.js"></script>
and move the bootstrap one to before the data tables
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script>
<script src="https://cdn.datatables.net/1.10.23/js/jquery.dataTables.min.js"></script>
<script src="vendor/jquery-easing/jquery.easing.min.js"></script>
<script src="js/sb-admin-2.min.js"></script>
<script src="vendor/chart.js/Chart.min.js"></script>
<script src="js/demo/chart-area-demo.js"></script>
<script src="js/demo/chart-pie-demo.js"></script>
<script src="js/demo/datatables-demo.js"></script>
I would personally have EITHER CDN OR downloaded versions
But take a look at the guidelines
https://getbootstrap.com/docs/5.0/getting-started/introduction/
https://cdn.datatables.net/
The order of the javascript files in an html file only makes a difference if they are interdependent. For example if you have a script that uses JQuery and you have declared the jquery script after your script, you will have problem. So when you have a script (or scripts) that is used from another script (or scripts) declare first the script (or scripts) that is used and then the script (or scripts) that uses it.
Ok so I am trying to load sb-admin-2 and the menu is not collapsing, I browsed for some solutions and none of them work for me, also as you can see the data-table is not working too and my tags looks like this:
<script type="text/javascript" src="{{STATIC_URL}}/static/lib/angular.min.js"></script>
<script type="text/javascript" src="{{STATIC_URL}}/static/lib/bootstrap.min.js"></script>
<script type="text/javascript" src="{{STATIC_URL}}/static/lib/angular-resource.min.js"></script>
<script type="text/javascript" src="{{STATIC_URL}}/static/lib/angular-ui-router.min.js"></script>
<script type="text/javascript" src="{{STATIC_URL}}/static/lib/angular-animate.min.js"></script>

<script type="text/javascript" src="{{STATIC_URL}}/static/lib/ng-file-upload.min.js"></script>
<!--SB ADMIN FILES-->
<script type="text/javascript" src="{{STATIC_URL}}/static/lib/metisMenu.min.js"></script>
<script type="text/javascript" src="{{STATIC_URL}}/static/lib/jquery.dataTables.min.js"></script>
<script type="text/javascript" src="{{STATIC_URL}}/static/lib/dataTables.bootstrap.min.js"></script>
<script type="text/javascript" src="{{STATIC_URL}}/static/lib/dataTables.responsive.js"></script>
<script type="text/javascript" src="{{STATIC_URL}}/static/lib/sb-admin-2.min.js"></script>
can you help me out guys.
ps: I am loading sb-admin through angularjs and django
gentos - i had a similar issue (sidebar not collapsing) and it turned out that i had overlapping jquery's. Once i removed the calls to both jquery and jquery.min files and just used a jquery link:
<script type="text/javascript" src="http://code.jquery.com/jquery-1.12.4.min.js"></script>
collapsible sidebar returned. I also reordered jquery and put the above link at the top of my HTML file (above bootstrap, metisMenu, etc.)
So I recently transfered over my files from one server to another. For some reason on the new
server I am getting odd errors in chrome under the network tab such as:
Uncaught ReferenceError: jQuery is not defined
Uncaught ReferenceError: autoResize is not defined
Some pages even stopped working!
I was messing around with the order of my script links.
Here is my current order:
<script type="text/javascript" src="assets/assetsz/js/modernizr.min.js"></script>
<script type="text/javascript" src="assets/assetsz/js/bootstrap.min.js"></script>
<script type="text/javascript" src="assets/assetsz/js/jquery.cookie.js"></script>
<script type="text/javascript" src="assets/assetsz/js/jquery.uniform.min.js"></script>
<script type="text/javascript" src="assets/assetsz/js/flot/jquery.flot.min.js"></script>
<script type="text/javascript" src="assets/assetsz/js/flot/jquery.flot.resize.min.js"></script>
<script type="text/javascript" src="assets/assetsz/js/responsive-tables.js"></script>
<script type="text/javascript" src="assets/assetsz/js/custom.js"></script>
<link href="assets/font-awesome/css/font-awesome.css" rel="stylesheet" />
<script type="text/javascript" src="assets/assetsz/js/jquery-ui.min.js"></script>
<script type="text/javascript" src="assets/assetsz/js/jquery-migrate-1.2.1.min.js"></script>
<script type="text/javascript" src="js/jquery-1.11.1.min.js"></script>
<script type="text/javascript" src="js/page-manager.js"></script>
<script type="text/javascript" src="js/tools.js"></script>
<script src='https://coinbase.com/assets/button.js' type='text/javascript'></script>
How should I order this and is there any way to make it so the order doesnt matter?
Thanks I have no idea what to search for this so I am stuck.
EDIT: New order. Less errors. http://prntscr.com/3y98gt

1rst place: JQuery
2nd place: JQuery Migrate
3rd place: JQuery UI
4th place: Bootstrap
Order of the rests are less important, but pay attention to don't call function before is loading by the script tag, eso
Another advice: separate CSS and JS files. It's a bad idea to mix everything.
Pay also attention: for performance reason, it's better to load JS at the end of the page. But CSS have to take place in the head section.
For starters, every script which uses jQuery should be loaded after your jQuery include. So, putting jquery-1.11.1.min.js on top should be a quick fix.
i have these jquery files included but some plugins work and some are not when i change squence then some plugins work but other give error. Please tell me best squence of these files. Thanks
<script type="text/javascript" src="js/jquery.min.js"></script>
<script type="text/javascript" src="js/jquery-1.10.2.min.js"></script>
<script type="text/javascript" src="js/jquery-1.9.1.js"></script>
<script src="js/jquery-ui.js" type="text/javascript"></script>
<script type="text/javascript" src="js/urdutextbox.js"></script>
<script type="text/javascript">
var jQuery_1_10_2 = $.noConflict(true);
</script>
<script type="text/javascript" src="js/jquery-ui.min.js"></script>
<script type="text/javascript" src="js/jquery-ui-timepicker-addon.js"></script>
<script type="text/javascript" src="js/jquery-ui-sliderAccess.js"></script>
<script type="text/javascript" src="js/jquery-ui-timepicker-addon.min.js"></script>
<script src="js/sitefunction.js"></script>
<script src="js/jquery.cookie.js"></script>
This would work.
<script type="text/javascript" src="js/jquery-1.10.2.min.js"></script>
<script type="text/javascript" src="js/jquery-ui.min.js"></script>
<script type="text/javascript" src="js/jquery-ui-sliderAccess.js"></script>
<script type="text/javascript" src="js/jquery-ui-timepicker-addon.min.js"></script>
<script src="js/sitefunction.js"></script>
<script src="js/jquery.cookie.js"></script>
<script type="text/javascript" src="js/urdutextbox.js"></script>
Also note that you do not need to include normal and minified versions (*.min.js). And since jquery-ui.js depends on jquery core code, it could be kept down to jquery core.
Also please note that you may not require two or more versions of a jquery core thing as it might not make any sense. Instead if you really wish to have some recently added functionality, please make your own custom file by going to jquery custom build at this link.
Just because a version of jQuery requires a certain version doesn't mean it won't work with a later version.
I would try to remove:
<script type="text/javascript" src="js/jquery.min.js"></script>
<script type="text/javascript" src="js/jquery-1.10.2.min.js"></script>
I would also completely remove this since there's no way for a plugin to work after you remove jQuery as a global.
<script type="text/javascript">
var jQuery_1_10_2 = $.noConflict(true);
</script>
Also, you're free to remove the type="text/javascript" from your script tags, no issue with it but it's not needed.
I'd put your site functions after all the other scripts are include as well, and I'd put jquery.cookie.js before the ui stuff, just as preference.
So, I'd end up with:
<script src="js/jquery-1.9.1.js"></script>
<script src="js/jquery.cookie.js"></script>
<script src="js/urdutextbox.js"></script>
<script src="js/jquery-ui.min.js"></script>
<script src="js/jquery-ui-timepicker-addon.js"></script>
<script src="js/jquery-ui-sliderAccess.js"></script>
<script src="js/jquery-ui-timepicker-addon.min.js"></script>
<script src="js/sitefunction.js"></script>
I want to play around with the ExtJs calendar and was wondering which js files i will need to include to do so?
The example from the Ext website includes many js files and I am wondering which ones are necessary and which ones are not. I'm assuming it depends on what functionality I wish the calendar to have, so lets just say I want to expose all of its functionality for now.
the following is a list of js and css files from the example on the Ext website:
<!-- Calendar-specific includes -->
<link rel="stylesheet" type="text/css" href="resources/css/calendar.css" />
<script type="text/javascript" src="src/Ext.calendar.js"></script>
<script type="text/javascript" src="src/templates/DayHeaderTemplate.js"></script>
<script type="text/javascript" src="src/templates/DayBodyTemplate.js"></script>
<script type="text/javascript" src="src/templates/DayViewTemplate.js"></script>
<script type="text/javascript" src="src/templates/BoxLayoutTemplate.js"></script>
<script type="text/javascript" src="src/templates/MonthViewTemplate.js"></script>
<script type="text/javascript" src="src/dd/CalendarScrollManager.js"></script>
<script type="text/javascript" src="src/dd/StatusProxy.js"></script>
<script type="text/javascript" src="src/dd/CalendarDD.js"></script>
<script type="text/javascript" src="src/dd/DayViewDD.js"></script>
<script type="text/javascript" src="src/EventRecord.js"></script>
<script type="text/javascript" src="src/views/MonthDayDetailView.js"></script>
<script type="text/javascript" src="src/widgets/CalendarPicker.js"></script>
<script type="text/javascript" src="src/WeekEventRenderer.js"></script>
<script type="text/javascript" src="src/views/CalendarView.js"></script>
<script type="text/javascript" src="src/views/MonthView.js"></script>
<script type="text/javascript" src="src/views/DayHeaderView.js"></script>
<script type="text/javascript" src="src/views/DayBodyView.js"></script>
<script type="text/javascript" src="src/views/DayView.js"></script>
<script type="text/javascript" src="src/views/WeekView.js"></script>
<script type="text/javascript" src="src/widgets/DateRangeField.js"></script>
<script type="text/javascript" src="src/widgets/ReminderField.js"></script>
<script type="text/javascript" src="src/EventEditForm.js"></script>
<script type="text/javascript" src="src/EventEditWindow.js"></script>
<script type="text/javascript" src="src/CalendarPanel.js"></script>
Calender is not included with the main extjs javascript files. You can use the calendar-all.js with the CSS instead of having the individual files added from the src directory. The calendar-all.js file is available in the calendar example folder itself.
So, you will require:
<!-- CSS files -->
<link rel="stylesheet" type="text/css" href="resources/css/ext-all.css">
<link rel="stylesheet" type="text/css" href="resources/css/calendar.css" />
<!-- Scripts -->
<script type="text/javascript" src="adapter/ext/ext-base.js"></script>
<script type="text/javascript" src="ext-all.js"></script>
<script type="text/javascript" src="calendar-all.js"></script>
FYI, you can also check out Ext Calendar Pro as well, which is the full product version of the example that shipped with 3.3. (Full disclosure: I am the author)
It has additional examples and complete docs and many bugs have been fixed since that example was created.
But yes, if you just want to play around with the one in 3.3 simply include calendar-all.js as mentioned above.
I think you only need this ones:
<link rel="stylesheet" type="text/css" href="resources/css/ext-all.css">
<script type="text/javascript" src="adapter/ext/ext-base.js"></script>
<script type="text/javascript" src="ext-all.js"></script>
Everything else is loaded by Ext JS by itself.
