I am using react.js
I'm trying to build a blog page.
there is a texterea tag to write a blog for the user.
now I want to add the function that allows users to add words that are linked.
so that when i show the text from that input words that are linked are clickable
enter image description here
like the blue words in wiki in the image above.
pardon my mistakes (1st question in StackOverflow)
I know about dangerouslysetinnerhtml. but not sure if it's the right way to do so. because then users can modify the code inside (i think). so what is the safe and right way to do so
Reading your case Markdown seems best option as it also supports links insertion. For rendering user entered markdown you may use library like React Markdown. For writing markdown textarea is fine as long as you write markdown syntax properly but you may want to consider libraries like React textarea markdown editor to make things easier.
I am building an Angular test preparation app (with Laravel 5.1 API). One of the requirements is to allow the user to print a certificate of achievement.
The client wants the person's name and credentials interpolated into the document (e.g., highlighted below). Here is a snapshot of the PDF template they sent:
The way I'm handling PDF viewing is simply by storing the file on S3 and giving them a link to that file.
Interpolating information into a PDF doc doesn't seem trivial and I haven't found much information on programmatically allowing this, but there are tools like DocHub, that allow you do edit while viewing the PDF.
I'm interested in learning:
is doing this programmatically trivial?
are there 3rd party tools I'm unaware of?
would I even be able to send this information along to the S3 link to interpolate in the first place?
Using PDF as a format for editing is usually a bad choice. If you have a form with fixed fields, then it's easy. Create a PDF template with an interactive form. In this form, based on AcroForm technology, you'll define fields with fixed coordinates, and a fixed size. You can then add content to these fields.
One major disadvantage with this approach is the lack of flexibility. Did you notice that I used the word "fixed" three times in the previous paragraph? If text doesn't fit the predefined field, you're out of luck. If the field is overdimensioned, you'll end up with plenty of white space. This approach is great if you can predict what the data will be like. A typical use case is a ticket or a voucher. For instance: the empty form is a really nice page, with only a couple of fields where an automated system can put a name, a date, a time, and a seat number.
This isn't the best approach for the example you show in your screen shot. The position of every line of text, every word, every character is known in advance. If you want to replace a short word with a long word (or vice-versa), then all those positions (of each line, of the complete page, possibly of the complete document) need to be recalculated. That's madness. Only people with very poor design skills come up with such an idea.
A better idea, is to store the template as HTML. See for instance chapter 5 of iText's pdfHTML tutorial, where we have this snippet of HTML:
<html>
<head>
<title>Invitation to SXSW 2018</title>
</head>
<body>
<u><b>Re: Invitation</b></u>
<br>
<p>Dear <name>SXSW visitor</name>,
we hope you had a great SXSW film festival experience last year.
And we would like to invite you to the next edition of SXSW Film
that takes place from March 9 until March 17, 2018.</p>
<p>Sincerely,<br>
The SXSW crew<br>
<date>August 4, 2017</date></p>
</body>
</html>
Actually, it's not really HTML, because the <name> tag and the <date> tag don't exist in HTML. All HTML processors (browsers as well as pdfHTML) ignore those tags and treat their content as if the tag was a <span>:
It doesn't make much sense to have such tags in the context of pure HTML, but it does make a lot of sense in the case of pdfHTML. With pdfHTMLL, you can configure custom tags, and have a result that looks like the PDFs shown below:
Look at the document for "John Doe" and compare it with the document for "Bruno Lowagie". The name "John Doe" is much shorter than my name, hence more words fit on that first line. The text flows nicely (we could also have chosen to justify the text on both sides). This "flow" is impossible to achieve with your approach, because you will never get a PDF template to reflow nicely.
OK, I get it, you probably say, but what about the practical aspects? You talk about a Java / .Net library, but I am working with Laravel and Angular.js. First, let me tell you that I don't think you'll find any good PDF tools for Laravel or Angular.js, because of the nature of PDF and those development environments (in my opinion, those technologies don't play well together). Regardless of my opinion, this shouldn't be much of a problem for you because you work in an Amazon environment. AWS supports Java, and the Java code needed to get pdfHTML working is minimal. Most of the code samples I wrote for the pdfHTML tutorial are shorter than 15 lines. So why not try Java and pdfHTML?
If you're already using Amazon services, why not use an amazon lambda function, in combination with iText7 (java), to generate the pdf on demand?
That way, you are guaranteed that the pdf is correct, and has nice layout every time.
Generating the pdf can either be done by:
converting HTML,
programmatically creating your entire document,
filling and flattening an XFA form.
I think for your use-case, either option 1 or 2 are the most sustainable.
Hi everyone I am developing an website and I wanna use one block similarly to this link https://careers.mit.edu/#block-views-facts-block.
Which it contains the flowing text and i liked it by the way so i wanna do it similar to this.
Would be grateful if any one suggest me the right way to do it.
they are using Drupal Views to output a text blocks, after custom animate function in JS/JQuery
check this file
https://careers.mit.edu/sites/default/files/js_injector/js_injector_2.js
Drupal.Careers.scrolling_text_animate
and few more to handle text position ...
animate function is quite big, you can do similar or look for an JQ plugin
Could anyone tell me if there's some way of "hooking in" to DotNetNuke so that I can, for example, search and replace text for ALL HTML modules on the site?
e.g. if I use an HTML editor and enter the text {{replace_me}}, then I could have some code that detects "{{replace_me}}" every time a page is rendered and replace it with something else.
Please note that this is a simple example - there may be other ways of "replacing" text - however the actual use case we have is very specific and there will be some significant processing to decide what to replace :) - so whatever solution we implement should basically be:
Get HTML from DB -> Process it however we wish in full C# -> Deliver the modified string.
Thanks!
I believe you can do this with the use of an HTTPModule. Ifinity.com.au used to sell a module that did this, looks like you might be able to download it now for free (maybe?) at http://www.ifinity.com.au/Products/Inline_Link_Master/Product_Details
I am developing a parser in ruby which parses some nonuniform text data. Can anybody tell me, where I can get a good number of plaintext data for that?
Here's you'll get a list of many:

And my fav is:

You could scrape Wikipedia (or just run a bunch of it through lynx -dump). That would also give you a vast source of non-English text as well. Project Gutenberg would be another good source of large amounts of plain text.
