jquery in javascript is not working - javascript

I have included jquery in javascript but it is not working wt to do
i hv also included jquery in it
<script type="text/javascript" src="/home/aman/html/book_cricket.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11./jquery.min.js"></script>

jQuery should run at the beginning
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11./jquery.min.js"></script>
<script type="text/javascript" src="/home/aman/html/book_cricket.js"></script>

The browser reads the javascript files in the order you place them.
Try reversing them to
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11./jquery.min.js"></script>
<script type="text/javascript" src="/home/aman/html/book_cricket.js"></script>

Does the order of javascript makes a difference?

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="js/sb-admin-2.min.js"></script>
<script src="vendor/chart.js/Chart.min.js"></script>
<script src="vendor/datatables/jquery.dataTables.min.js"></script>
<script src="vendor/datatables/dataTables.bootstrap4.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>
<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.

scripts included in partials dont work as expected in ejs

I use lodash accross my website and its now telling me that uniqBy is not a function. I thought maybe this was due to me using an older version of the library so I updated it and still had the same issue. I do bring it into the html via ejs <%- include %> but when using something like ejs lodash wont work as expected. I try to use _.uniqBy to sort an array but unless I specifically insert a lodash script into html it wont work.
<%- include ../partials/scripts.ejs%>
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<script type="text/javascript" src="https://cdn.datatables.net/v/bs/dt-1.10.12/datatables.min.js"></script>
<script type="text/javascript" src="/js/accounting/dataTables.buttons.min.js"></script>
<script type="text/javascript" src="/js/accounting/jszip.min.js"></script>
<script type="text/javascript" src="/js/accounting/pdfmake.min.js"></script>
<script type="text/javascript" src="/js/accounting/vfs_fonts.js"></script>
<script type="text/javascript" src="/js/accounting/buttons.html5.min.js"></script>
<!-- <script type="text/javascript" src="/js/lodash.js"></script> Works with this -->
<script type="text/javascript">
// Returns undefined unless the lodash script tag is uncommented
console.log(_.uniqBy);
</script>
<script type="text/javascript" src="/js/cost/list.js">//Lodash used in here</script>
<%- include ../partials/footer.ejs%>
And the scripts partial is:
<script type="text/javascript" src="/js/jquery.min.js"></script>
<script type="text/javascript" src="/js/bootstrap.min.js"></script>
<script type="text/javascript" src="/js/bootstrap-formhelpers.min.js"></script>
<script type="text/javascript" src="/js/select2.min.js"></script>
<script type="text/javascript" src="/js/moment.min.js"></script>
<script type="text/javascript" src="/js/lodash.js"></script>
<script type="text/javascript" src="/js/jquery.cookiebar.js"></script>
<script type="text/javascript" src="/js/slide.js"></script>
<script type="text/javascript" src="/js/email.js"></script>
<script type="text/javascript" src="/js/jspdf.js"></script>
In my cost/list.js I use jquery with document.ready() before I use lodash so my question is why does this happen? I thought maybe first it was scope but It cant be as I use these files everywhere and never had this issue before. Then I thought maybe it was the loading as the ejs including of partials could load either before or after the page is ready but my js cost/list.js should wait for it to be ready due to the $(document).ready(). Im not sure what the issue is and any ideas as to whats happening with the ejs includes would be great.
Went through the page a bit more and found out its pdfmake use lodash too but they use an older version(3.x) whereas today im on (4.17.4) this is why as pdfmakes lodash comes last it takes precedence and becomes the global. Hopefully this will help someone in the future. Check your scripts I went through them one by one moving my lodash script after every other script and found it that way

Simple JQuery Drag and Drop not working at all

I am new to JQuery stuff ,but this is ridiculous ,i cant do drag and drop work
.php file
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>PHP Test</title>
</head>
<body>
<span id="drag">Drag me</span>
<script type="text/javascript" src="js/jquery-2.1.3.min.js"></script>
<script type="text/javascript" src="js/drag.js"></script>
<script type="text/javascript" src="js/jquery-ui.js"></script>
</body>
</html>
my drag js file
$(document).ready(function() {
$('#drag').draggable();
});
By the way, do i need to have JQuery UI to make drag and drop stuff?
Thank you
You should include the libraries in the correct order:
<script type="text/javascript" src="js/jquery-2.1.3.min.js"></script>
<script type="text/javascript" src="js/jquery-ui.js"></script>
<script type="text/javascript" src="js/drag.js"></script>
Your custom code (drag.js) should be last, after jquery and jquery-ui have been loaded.
The draggable() function requires jQueryUI to work. After including jQueryUI your code works fine.
$('#drag').draggable();

I would use cdn to save on speed and resources, and also be sure that you have a working copy. The order was probably your issue, however, as people mentioned above.
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jqueryui/1.11.2/jquery-ui.js"></script>
You should first load UI script and use it after.
<script type="text/javascript" src="js/jquery-2.1.3.min.js"></script>
<script type="text/javascript" src="js/jquery-ui.js"></script>
<script type="text/javascript" src="js/drag.js"></script>
Important: don't forget jQuery 2.* browser compatibility:
https://jquery.com/download/#jquery-2-x
It doesn't support IE 8 or earlier!

what is the squence of jquery files

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>

Conflict between the different INCLUDED JavaScript files

When I include the enhance.js plugin it makes a conflict with other jquery plugins, such as UI jquery plugins
I can't use the date picker functions for example .
what is the possible solution ?
From documentation: http://api.jquery.com/jQuery.noConflict/
<script type="text/javascript" src="other_lib.js"></script>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$.noConflict();
// Code that uses other library's $ can follow here.
</script>
And/or you can use aliasing here:
<script type="text/javascript" src="other_lib.js"></script>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$.noConflict();
jQuery(document).ready(function($) {
// Code that uses jQuery's $ can follow here.
});
// Code that uses other library's $ can follow here.
</script>
