This works great and all, but i have a fear that1) the code might get changed without me knowing, then i encounter problems and try to debug for days / hours before finding that the code at this site changed

is jQuery's CDN (provided by Media Temple). The code at -1.4.4.js will never change; jQuery will release a new version (which will be at a different URL), if anything needs to change (which happens all the time; version 1.5b was released today).

This will install jQuery to Bower's install directory, the default being bower_components. Within bower_components/jquery/dist/ you will find an uncompressed release, a compressed release, and a map file.

We have created the jQuery Migrate pluginto simplify the transition from older versions of jQuery. The plugin restores deprecated features and behaviors so that older code will still run properly on newer versions of jQuery. Use the uncompressed development version to diagnose compatibility issues, it will generate warnings on the console that you can use to identify and fix problems. Use the compressed production version to simply fix compatibility issues without generating console warnings.

The jQuery team is constantly working to improve the code. Each commit to the Github repo generates a work-in-progress version of the code that we update on the jQuery CDN. These versions are sometimes unstable and never suitable for production sites. We recommend they be used to determine whether a bug has already been fixed when reporting bugs against released versions, or to see if new bugs have been introduced.

The code is hosted and developed in the jQuery GitHub repository. If you've spotted some areas of code that could be improved, please feel free to discuss it on the Developing jQuery Core Forum. If you'd like to participate in developing jQuery, peruse our contributor site for more information.

All source code is kept under Git revision control, which you can browse online. The repository's README has more information on building and testing your own jQuery, as well as instructions on creating a custom build that excludes some APIs to reduce file size.

So the question is how and where do I reference external JQuery libraries in the widget, and how would I write corresponding code in Widget.js? I'm assuming that I can put the hidden popupdiv and the btnShowModalDialog button in Widget.html, right?

As far as where to insert the code inside of widget.js, inside the "startup: function (){" works fine for me. Yes, you are able to insert the popupdiv and the btnShowModalDialog button inside of Widget.html.

Bootstrap is developed mobile first, a strategy in which we optimize code for mobile devices first and then scale up components as necessary using CSS media queries. To ensure proper rendering and touch zooming for all devices, add the responsive viewport meta tag to your .

Also consider that adding a "non-secure" script on a secure site (depending on your browser) will temporarily block insecure (un-secure? non-secure?) items. On Chrome, you may have to click the "shield" in the address bar (and select 'load anyway') to load the code.

If I use jQuery, the script is loaded at the end of the tag. This seems to make it impossible to use jQuery code between ... since the jQuery object is not defined when the script is executed. Any idea how to fix this?

The whole thing came up as there is the header feature in BSS to get code on every page. Hence I thought, than code that I need on every page should go into the header. Now I need to include my JS file on every page, which works too but IMO is a bit contradiction to the announced header feature.

Right click the page name and choose Properties. There's a tab there for adding things to the Head, and that includes javascript/jquery, css, etc. Whatever you put there you put in as code same as you would in the head when coding it normally.

P.S. This may cause issues with the jquery and such in the footer so you'll need to work that part out using Saj's method to override what comes first, but this feature has been there for quite some time to be able to add things to the Head of your pages. It is also page specific.

Sure, that's why I'm asking about the "missing" behavior. And I don't think the way to go is to add jQuery myself in the header and try to get around it in the body... However, I have a solution so no big deal. IMO BSS ss just not that flexible as it should be in the "jQuery code in the header" case.

Another way to get around some of what you're trying to do by adding code to the body instead of the footer (not head code, but within the body itself) is to just include it in a custom code box. That works just as well as anything else and you can put that custom code box within any section you want so you can tie it to whatever code the scripts belong to pretty easily. Where there's a will there's a way, just not always the most efficient is all lol. If we ever get the ability to actually edit the code freehand like you can with Pinegrow, that will be a day to recon with for sure!

Yes, sure it's possible. That's not the problem. The problem is, that if you want to use jQuery code, jQuery lib needs to be loaded already. Which is not the case for HEADER code, as it's loaded later at the end of BODY.

One extreme important programming pattern is DRY. Which implies that "cut & paste" is worst practice too. To avoid managing duplicated code and utilize the power of BSS as generator, it makes sense to add code to the HEADER on the project level. With this, the generator takes care of adding it to every page, while I have only one place where the code is managed.

Of course I can add the code to a separate JS file, which I do. But again, this is bad practice too. But now in the other direction. If I only want to add code to one or some pages that doesn't work (to my knowledge) because the JS file gets added to every page. So, you load code that's not used (bad practice), which takes time, might cause problems etc.

I am using the EXACT code he has done in this video. I have tried it on the workspace and it seems to work fine there. However when I download the workspace files and try to run them locally on my Mac, the jQuery does not work.

Our fix is to only apply this code where it is needed. Fortunately, because of the different parsing behavior in IE9, we can keep the fix in IE9 without exposing it to the same vulnerability as other browsers. Please upgrade when you get a chance to avoid these vulnerabilities.

When you move beyond adding simple enhancements to your website with jQuery and start developing full-blown client-side applications, you need to consider how to organize your code. In this chapter, we'll take a look at various code organization patterns you can use in your jQuery application and explore the RequireJS dependency management and build system.

The first step to code organization is separating pieces of your application into distinct pieces; sometimes, even just this effort is sufficient to improve the structure of your code and its maintainability.

An object literal is perhaps the simplest way to encapsulate related code. It doesn't offer any privacy for properties or methods, but it's useful for eliminating anonymous functions from your code, centralizing configuration options, and easing the path to reuse and refactoring.

If this were the extent of our application, leaving it as-is would be fine. On the other hand, if this was a piece of a larger application, we'd do well to keep this functionality separate from unrelated functionality. We might also want to move the URL out of the code and into a configuration area. Finally, we might want to break up the chain to make it easier to modify pieces of the functionality later.

For non-trivial features, object literals are a clear improvement over a long stretch of code stuffed in a $( document ).ready() block, as they get us thinking about the pieces of our functionality. However, they aren't a whole lot more advanced than simply having a bunch of function declarations inside of that $( document ).ready() block.

In the example above, we self-execute an anonymous function that returns an object. Inside of the function, we define some variables. Because the variables are defined inside of the function, we don't have access to them outside of the function unless we put them in the return object. This means that no code outside of the function has access to the privateThing variable or to the changePrivateThing function. However, sayPrivateThing does have access to privateThing and changePrivateThing, because both were defined in the same scope as sayPrivateThing.

It seems the big reason for this is in the "Reduce the impact of third-party code" section. I have noticed that one script in particular loads in with pretty drastically different speeds (from about 300ms to 800ms). The script is coming from shopify and I'm just wondering what it is, if I can remove it somehow, or at least just curious why it loads fast sometimes but slow others? =11586021193639794548165...

So it seems that Wordpress only runs on v1.12 of jquery. I want to use the latest version on my site, however this breaks the Beaver Builder, which I also want to use. I will get my company to buy the premium version, if I can get it work correctly.

jQuery also provides a paradigm for event handling that goes beyond basic DOM element selection and manipulation. The event assignment and the event callback function definition are done in a single step in a single location in the code. jQuery also aims to incorporate other highly used JavaScript functionality (e.g. fade ins and fade outs when hiding elements, animations by manipulating CSS properties). ff782bc1db
