I am trying to create a web page with the following :
Buttons and input fields etc. in the top half of the page that allow the user to define certain criteria, when the user clicks submit, the page calls some php code that writes an iframe referenced html file which is then shewn on the bottom part of the web page.
I think I understand how to do this for a web page referring to a single iframe document source but there may be more than one user running the page so how do I have the iframe pointing to the correct iframe source for each user?
Some web searching sugests that this is the kind of thing done with XMLHttpRequest, I'll have a look into that.
If I understand correctly, your PHP code creates an HTML file and then loads it in an iframe.
You could have your PHP script output the HTML, then load the PHP script in your iframe directly. Now there is no way for another user to accidentally get the other users' output.
I'm not sure if I understand exactly what you want to do.. but if you have already existing database of users, make a new table with Iframe preferences... so when they click submit, the preferences will be saved to the database with the user_id.. so next time just check if the user has already chosen... if yes, get the preferences from database.. if not -> redirect him to do so.
I don't know if that's exactly what you want

Background:
I need to allow users to create web pages for various products, with each page having a standard overall appearance. So basically, I will have a template, and based on the input data I need the HTML page to be generated for each product. The input data will be submitted via a web form, following which the data should be merged with the template to produce the output.
I initially considered using a pure templating approach such as Nunjucks, but moved to ReactJS as I have prior experience with the latter.
Problem:
Once I display the output page (by adding the user input to the template file with placeholders), I am getting the desired output page displayed in the browser. But how can I now obtain the HTML code for this specific page?
When I tried to view the source code of the page, I see the contents of 'public/index.html' stating:
This HTML file is a template.
If you open it directly in the browser, you will see an empty page.
Expectedly, the same happens when I try to save (Save As...) the html page via the browser. I understand why the above happens.
But I cannot find a solution to my requirement. Can anyone tell me how I can download/save the static source code for the output page displayed on the browser.
I have read possible solutions such as installing 'React/Redux Development Extension' etc... but these would not work as a solution for external users (who cannot be expected to install these extensions to use my tool). I need a way to do this on production environment.
p.s. Having read the "background" info of my task, do let me know if you can think of any better ways of approaching this.
Edit note:
My app is currently actually just a single page, that accepts user data via a form and displays the output (in a full screen dialog). I don't wish to have these output pages 'published' on the website, and these are simply to be saved/downloaded for internal use. So simply being able to get the "source code" for the dislayed view/page on the browser and saving this to a file would solve my problem. But I am not sure if there is a way to do this?
Its recommended that you use a well-known site generator such as Gatsby or Next for your static sites since "npx create-react-app my-app" is for single page apps.

If I'm understanding correctly, you need to generate a new page link for each user. Each of your users will have their own link (http/https) to share with their users.
For example, a scheduling tool will need each user to create their own "booking page", which is a generated link (could be on your domain --> www.yourdomain.com/bookinguser1).
You'll need user profiles to store each user's custom page, a database, and such. If you're not comfortable, I'll use something like an e-commerce tool that will do it for you.
You can turn on the debugger (f12) and go to "Elements"
Then right-click on the HTML tag and press edit as HTML
And then copy everything (ctrl + a)
I've got a C#, Kendo MVC, Razor site. There's a Kendo grid where one of the cells has a hyperlink to a pdf file, like this:
File 123
Clicking on the link opens a pdf in a new browser tab. The problem is, the URL is visible in the browser and can be changed to see another file. For example, the user could replace 123 with 456 and see File456.pdf. I need to do two things:
Hide the filename in the URL when the pdf is opened.
Hide the URL when the user hovers over the hyperlink.
Alternatively, I'd take a way to click the link (without the user seeing the URL) and download the file, but I think whether to download or view the file is browser specific.
I would just create an event to send the user back to the controller and handle the opening or download there, but the Kendo grid complicates that and this, as usual, needs to be changed right away. I'll take suggestions on how to manipulate the Kendo row to open a pdf, but I'm hoping there's a simple way to change just hide the URL from the user.
The problem is, the URL is visible in the browser and can be changed to see another file.
In my opinion the correct approach in this case would be not to pretend to hide something from the user, but rather know who your users are and implement authorization on your server. This means that if user A attempts to access file 123 that belongs to user B he gets denied. But if he attempts to access file 124 that belongs to him, then why care that he modified the url in the browser? After all user A accessed his own file. So instead of serving a static file directly, you could put those files into a folder that is not directly accessible and serve them through a controller action that will apply the necessary authorization logic (does the file that the user is trying to access actually belong to him before serving it?).
So my advice in this case for you would be to implement authorization on your server based on the resources that he is trying to access.
If you handle the redirection in JS I think it won't show the url. For example
<p onclick="redirect('http://example.com/Files/File123.pdf')">Click here for PDF</p>
<script>
function redirect(link)
{
window.location = link;
}
</script>
I am trying to have a single GAS project that changes its UI by serving up different HTML pages based on what the user clicks. I cannot figure out how to serve up different HTML from the script, replace the current browser page and retain state. Any help appreciated. Thank you.
I use two options:
Have a main page which has buttons or text areas with onchange set to a function which calls back to the server side and gets new page data, then replace the current page or a portion of the page, with the new page.
Pass parameters in the URL and have the server side doGet() parse the parameters and branch to load a given page based on these values.
I have used a combination of both of these effectively. Basically I have a div which has my "menu" and a div which is the section to be replaced. My menu changes and then data is sent back to the server to get the dynamic body. The HTML is returned and then I replace using innerHTML.
In the same code I offer the ability to pass menu values via the published URL. This allows me to go directly to some values if I so choose as I have a Google Site where we embed the script into pages and the menu selections may be specific to that page. It allows us to use an iFrame to show the web app and go directly to the pertinent interface.
With google.script.run you can run any script on the server from the html page. By communicating with the server you have access to PropertiesService which gives you the capability to store information between pages. Personally I like the HTML Service createHtmlOutput(html) because I can edit the html without having to edit a separate page.
I decided to answer your question here so that I could use the code section.
Question:
I am actually looking to avoid manipulating the HTML and serve up a
completely different HTML file stored in the project. How do I make
the page call the script again and replace itself with the new
content?
We I'm guessing that completely replacing the page is not really what you want because the user will suffer a page refresh. But you could create divs like this:
<style>#R01{display:none;}</style>
<div class="replaceable" id="R01"></div>
If you put all your replaceable content in divs like that then you can request content from the server via calls like this:
google.script.run
.withSuccessHandler(updateConversation)
.withFailureHandler(showStatus)
.getConversation();
and put the new content into the appropriate divs and then change the css with another pair and turn the old content off and the new content on. Thereby avoiding a page refresh. Don't forget to save the old data into the PropertiesService first. So I don't think changing the entire page is the way to go but I could be wrong. I think just changing some of the internal content will avoid the need for a total page refresh. If you want to change images you can avoid another download by using CSS Sprites
I've an app, which loads data from database. In a table I'm storing some URLs EX: https://facebook.com. Remember these URLs are dynamic and are controlled in admin panel.
Now, I need to get contents of these URLs and display it inside iFrame or inside a div within my app. Idea here is user should not go away from my app.
When I tried to load https://facebook.com it never loads because they've (X-Frame-Options) enabled.
Is there any solution for this?
You cannot tell the browser to ignore the security instructions provided by the third party site. That would defeat the object of having them in the first place.
If you want to display the content on your site, then you will have to display it from your own server (e.g. by using a server side process to read the data from the third party site and serve it from your own). Obviously, this will mean that you cannot (for example) load Facebook using the user's own credentials.
I am trying to make a Chrome extension for personal use that makes all the password fields type="text", so I can see the clear passwords. (I know that I can probably find something like this in the Chrome store, but it's something I want to do myself).
I am however having a hard time accessing the actual page content (the page I'm viewing in the tab). If I do
document.getElementById('text')
this selects the element from background.html not the page I'm viewing. How can I access the actual page?
Also, is there a way I can include an external javascript file so I can use functions from there?
You would need to use content script - javascript file injected into an actual page with access to DOM and events.
