I am using ionic v4. I have a web page where when completing a form, a PDF file is downloaded. I want to perform this same action on the Android device.
How can I do it using webview?
Can you provide more information?
You just want do download a specific PDF link file? Maybe something like this:
Using href
Define a variable with the desired URL link:
var url="https://www.w3schools.com?name=ADAM"
Insert into your html file:
< a target="_blank" href="{{url}}">PDF< / a>
If you share some code I can help you out more...

I'm working on a URL preview widget, so I'd like to extract the meta tags from the HTML of a given URL.
However, the problem is that websites like Twitter don't return the entire HTML when they detect there's no JavaScript engine enabled (i.e. doing a GET request from the http package).
So, I'd like to know if there's any workaround for these cases, for example, using some kind of headless browser to get the entire HTML.
Thanks!
We know that we can use pages or components in ionic. These pages and components contain .html files, which have html markup. When we build the app, all these files are bundled into the app.
My question is whether we can use or embed external .html files and act on that .html file.
For example: if we have a login page which contains username and password fields and submit button. We have already defined css for this page. There is a requirement for my project to embed external .html file and use it as login page. It may have a different css.
if you mean that you have html tags in JSON response for example and you want to add them to ionic just do :
<div [innerHTML]="your-JSON-response-Html"></div>
I tried pdf, txt and png file url, only pdf url can't be open with browser if click the url, but trigger download.
I google this but only got how to fix, like instead with google doc or use pdf.js, or other html code.
What is the reason? the website ? Forgive me that i have no idea of website architecture.
When you get a file from a website, it has a content type sent along with it. Depending on the content type, the browser may choose to display it. For example, content type "application/pdf" might be shown in a browser, but "application/octet-stream" will be downloaded.
The raw URL on GitHub has content type "application/octet-stream" (a binary file) so that it will be downloaded.
The only way around this, since you can't change GitHub's code that sets the content type, is to get the data from JavaScript and parse it there -- by using pdf.js or something similar.
In my cordova inappbrowser app, pdfs can be downloaded by calling a RESTful service that streams the content to the user's browser (see html snippet below). This works fine on iOS and using Google Chrome directly on Android but not when doing it through cordova inappbrowser. Clicking on the link doesn't do anything. I've tried many of the suggestions here including using gview but no result.
The tag in html is an href (I tried using window.open as well) that evaluates to something like https://xxx/member/get_pdf/217521359ashr868af6as. Using target='_blank' (tried _system also)
where the value after get_pdf is a guid (value above is not the real guid)
The google viewer workoaround that many people propose works fine with a physical pdfs but my files are streamed back from the service above and gview doesn't recognize it as a pdf and shows error 'preview not available' and its not an option to store them physically. Is there some specific header to set to make gview recognize the streamed response as a pdf? I set content_type, Content-length, tried adding Content-disposition with a filename also. No go.
Any suggestions appreciated.
Thanks,
Patrick
I recently develop a shortener URL script, now I'm trying to add Addthis buttons but the problem is that is sharing the current URL of the site is on. I want the Addthis buttons share the URL that is inside of the URL Input field anybody got some idea on how to do it?
Basically I want to add Addthis buttons and share the URL from a Input field that got the URL shorted .
The Real Question: How can you specify a custom URL for Addthis?
jQuery Solution
HTML
<a href="http://www.addthis.com/bookmark.php" class="addthis_button" id="youmusthaveanid">
jQuery
$('#youridhere').attr('addthis:url', $('#yourinput').val);
Note: Remember you will have to trigger this on every update of the text box if it's content changes after the Javascript has been run on initial load.
PHP Solution
HTML/PHP
<a href="http://www.addthis.com/bookmark.php" class="addthis_button" addthis:url="<?=$yourvariablehere?>"
