Php file script src

At first such an notion may seem strange, even impossible; after all, who among us isn't familiar with that barrier dividing server side and client side scripts that prohibit the two from interacting? Well, it turns out superficial exchange is allowed. The syntax to referencing a PHP file using external JavaScript is consistent enough with what we already know:. So you're probably wondering at this point: "So what's the catch? Think of it as a dynamic.

An allow-list for specific inline scripts using a cryptographic nonce number used once. The server must generate a unique nonce value each time it transmits a policy.

It is critical to provide an unguessable nonce, as bypassing a resource's policy is otherwise trivial. See unsafe inline script for an example. Specifying nonce makes a modern browser ignore 'unsafe-inline' which could still be set for older browsers without nonce support. Note: The CSP nonce source can only be applied to nonceable elements e.

A sha, sha or sha hash of scripts or styles. The use of this source consists of two portions separated by a dash: the encryption algorithm used to create the hash and the baseencoded hash of the script or style. In CSP 2. CSP 3. The strict-dynamic source expression specifies that the trust explicitly given to a script present in the markup, by accompanying it with a nonce or a hash, shall be propagated to all the scripts loaded by that root script. At the same time, any allow-list or source expressions such as 'self' or 'unsafe-inline' are ignored.

You should replace them with addEventListener calls:. The risk might be small, but why take it when you could avoid it? IMO, they chose the right course of action. Not useless. I could use this to hide some proprietary calculations that are normally exposed when using straight up JavaScript. Decent tip. It is useless, because you could just do that with Ajax instead. Very handy if you want to mix small javascript-generated content with static html. Best of both worlds, if done properly.

The javascript got the creation date of the account and number of views of that particular page with sessions from the database, then wrote those values to a javascript file. If JS detected that the account was less than 5 minutes old and that the page had been viewed 2 times or less due to refreshes, coming back to the overview page via link, etc it showed a welcome message. I would also recommend adding a header call to declare the content type within the php. Although the script tag likely guesses it correctly, it never hurts to be more thorough.

And I cannot think of any browser that does not support iframes. But definitely an option in that case, and as far as I can tell, pretty much has the same result.

And has the added benefit of not relying on JavaScript, so that actually seems like a stronger solution for that bizarre circumstance. You may not like it, but it is part of the HTML5 standard … sorry, just being picky. The post kept me interested. Oh, of course. XSSI has many features, including pattern matching. Many web sites work just fine without a database back end, especially if they use the database simply to store documents. In fact, you can even build a light content management system using XSSI.

Thanks for the info. But of course, in PHP, you have the option of setting the time zone in the code. Well, those requests came from the project managers, who get them from the client. Ok now I can see where this could grow to be something more. A php library to do javascript dom manipulation. I think some might be missing the point here… This is just a simple example of something that was crafted out of necessity in a nick of time.

Far from it, think again… This opens the possibility to have JS scripts that would contain stuff you have on your database easily! We are talking about dynamic Javascript here! How about you have a table with the localized language strings, where you could add new entries and get others to help you translate to many other languages?

You could also cache the results server side as well, making deployment of localized custom scripts far easier than it was before. Hey Louis, I used the same trick in getting the JavaScript content from the server. As all of us know each and script tag inclusion in html makes an http request to the server and makes page loading slow and I was having lot of individual JavaScript files. So to reduce http requests to server I created an php file to combine all the JavaScript files together, then I included single script tag by calling that php file.

I could use this to hide some proprietary calculations that are normally exposed when using straight up JavaScript…. That is what I am using on my html pages. So it is cetainly NOT useless! OK, I set up a couple of test files to check this out, but it fails to run as expected.

My HTML file looks like this:.
