I was looking in HtmlPurifier documentation, but I can't see nothing about that.
Let's say I have
<div class="codebox">
All html tags here - Even <div class="codebox">another code box</div>
</div>
I want to parse the content of the first <div class="codebox"> so it can be readable as plaintext.
Can htmlpurifier do that ?
Out of the box HTMLPurifier can't do that and there is no config setting, that I know of, that can convert only the first <div> tag to plain text without converting the entire document. And even for converting the entire document to text the HTMLPurifier is neither needed nor recommended.
You can extend functionality of HTMLPurifier but unless you are an expert coder, I wouldn't recommend doing that.
However if you want to convert a part of the HTML document to text then break it into parts and run the part which you want to convert to text through
strip_tags()
PHP Manual page on strip_tags
You could convert all the div tags in your document to plain text with this configuration directive:
$config->set(HTML.ForbiddenElements, 'div'); //This will black list 'div' tag
And if you absolutely insist on converting your entire document to text using HTMLPurifier then here is the config directive that will do that.
$config->set('HTML.Allowed', ''); //This will white list NO tags ''
In HTML I can do:
<textarea>
line 1
line 2
line 3
</textarea>
However, the same thing doesn't work with the JSF <h:inputTextarea>, as I have to specify the value attribute instead of the body. Is there a way that I can specify a multiline value? Ideally I would like to be able to do it as seamlessly as in HTML, ie with no \n and actually putting it onto multiple lines, for easy readability.
You could try this :
<h:outputFormat escape="false" value="Line 1<br/>Line 2" />
Which would render:
Line 1
Line 2
Note:The escape="false" means you can embed html, like lists etc...
or else we can even try like this:
Alternatively you could set readonly to true on the inputTextArea and set the rows attribute.
I Hope this will help you
Well, I couldn't find a way to include the textarea content directly into the .xhtml, while keeping the content on several lines. There's probably a way with some javascript by using a different tag and then copying it in or something, but I wanted to keep it fairly clean.
What I ended up doing was using the value attribute of h:inputTextarea and I populated it from my managedBean. I created text files of the content I wanted (they were quite big files) and loaded them into the managedBean property using a FileReader. When you assign them to the value of the h:inputTextArea, the \n etc are respected, so that it gives you the identical effect to if you had hardcoded the text into the .xhtml between textarea tags.
I have a heredoc string
html =<<EOF
<span>
Hello hello 123
</span>
<a>Link1</a>
<a>Link2Link2</a>
EOF
If I say puts html, it will give html as it is, meaning with new lines which is fine. If I call p html I'll get the html without line breaks.
However, what I really need to do is to convert this html into picture and it should have line breaks. Here is how I do that:
kit = IMGKit.new html, quality: 30
# using Magick::Image ......
# some code which is not important....
img.write("my_gif.gif")
It's almost fine except the fact that the result html, as I've already said, doesn't have line breaks, it has only one line:
<span>Hello hello 123</span><a>Link1</a><a>Link2Link2</a>
Of course, if I add <br /> tags, it all will be worked out. But I'm not able to do that for some reason, I want not to use <br /> and still have line breaks.
This is not the problem of IMGKit or Rmagic as I'm pretty sure.
So how do I achieve that?
I agree it is not a problem with IMGKit - it is doing what it is supposed to do - render the HTML. There is also nothing wrong with the heredoc, and nothing magical you can do with Ruby's representation of the HTML such that literal whitespace (spaces, tabs, newlines) in HTML source become visible when rendered.
The most common rendering of source whitespace by HTML viewers is that any length of pure whitespace (whether spaces, tabs, newlines or any combination) is rendered as a single space -> <- in the view. Additionally, whitespace between one element end and another starting is often completely ignored (although the rendering of the elements themselves may cause layout/spacing effects in the view).
You could, however, do something like this:
kit = IMGKit.new html.gsub(/\n/,"<br/>"), quality: 30
and have line breaks rendered without adding <br/> to your heredoc.
I've got wiki style content which is sanitized and stored in another field of the db for output as html. The original body field I'm not sure how to deal with as when I santize it characters are escaped and don't display well in the textarea.
What are the dangers of unsafe content in textareas? I'm sure I read previously that downloading such textarea content with ajax is preferable but I'd rather not go down that route if not necessary.
all HTML tag are no safe. by example if you close the textarea, you can add all nez HTML tag or what you want like JS. So it's exactly like inside a non textarea tag.
HI All,
I know this is bit strange question, but please suggest.
I want to create a link on website url content in input type"text" field not any other html tag,Is it possible and if yes how.
Regards & Thanks

I don't know whether I understood your question correctly or not. Based on my understanding I gave the answer. Feel free to raise your question. Nothing is impossible.
</input>
It displays a text box. You can enter any data into it. If you press enter key then it forwards the page to Google.com
You can use SPAN instead of INPUT. This also serve the same purpose.
<a href="http://www.google.com" ><span style="border:1px solid blue;" >Link</span></a>
This is unfortunately not possible in the way you've asked it in HTML 4 or below. Even with HTML5 which has several new INPUT TYPEs, including URL, it only does validation and has some other useful functions, but won't give you want you want.
You might look for some jQuery plugins that can help you do this, most use the same principals behind Rich Text or other online/web-based HTML WYSIWYG editors. I've had trouble locating them myself.
These 3 situations (that I can think of right now) are pretty much what you will face natively with HTML4 or below, as text in an actual HTML4 INPUT textbox is pure text. It is not html and therefore NOT clickable. Here are some variations:
The INPUT tag's VALUE attribute, also referenced as the corresponding DOM object's "value" property (which is basically what you've been doing, and the most you can hope for, if you decide that you MUST have the text that's ACTUALLY inside the textbox (because the text inside the textbox is the VALUE attribute, as I have it with "http://yahoo.com" in this example):
<input id="myTxtbox" type="text" value="http://yahoo.com">
where the INPUT's VALUE = "http://yahoo.com", which you can retrieve with:
in pure javascript:
document.getElementById("myTxtbox").value
in jQuery:
$("myTxtBox").val()
When your link/url is the text in between the and , i.e. the text/innerText of the textbox. This is useless for your question/scenario since it's not clickable, and more importantly NOT INSIDE the textbox. However, someone might want to use this to retrieve any text that you may be using as a label (if you're not using the <label> tag itself already that is):
<input id="myTxtbox" type="text">
http://yahoo.com
</input>
The textbox's text/innerText is NOT an attribute here, only a DOM object property, but can still be retrieved:
pure javascript:
document.getElementById("myTxtbox").innerText
jQuery:
$("myTxtBox").text() -- you would use this to capure any text that you may be using as a label (if you're not using the tag).
The result being: http://yahoo.com
When your link/url is the form of an ANCHOR () with an HREF to your url (and visible link text) in between the and , i.e. the innerHTML of the textbox. This is getting a bit closer to what you want, as the link will appear as, and function as an actual link. However, it will NOT be inside of the textbox. It will be along side it as in example #2. Again, as stated in example #1, you CANNOT have actual working HTML, and therefore a working 'link' inside of a textbox:
<input id="myTxtbox" type="text">
<a href="http://yahoo.com">
http://yahoo.com
</a>
</input>
Once again, similarly to example #2, the textbox's innerHTML is NOT an attribute here, only a DOM object property, but can still be retrieved:
pure javascript:
document.getElementById("myTxtbox").innerHTML
jQuery:
$("myTxtBox").html()
The result being: http://yahoo.com
You could simply do this :
<input type=text value="link" readonly>
So whenever somebody clicks the textbox, it works as a link, and since it's read only, there wont be any text input/change.
Be careful tho, for it wont look like a regular link and might cause confusion, or may be misinterpreted as a normal textbox.
This is how I did it with JavaScript and JQuery. This wraps the entire text field in a hyperlink, so essentially the entire text field is click-able, which may not be the functionality you are looking for. It worked for my purposes though.
The reason I didn't just use a $(nameTextField).click(function(){...}) structure is because the text field I'm using has the disabled attribute set, so click functions aren't fired. That's why I had to wrap the text field in a hyperlink.
// Make person name a hyperlink to page in new tab
var nameLink = "/exampleUrl/?initStudentId=$" + studentId;
$("#studentNameLink").replaceWith($("#studentNameLink").html()); // Unwrap any previously wrapped text fields
$(nameTextField).wrap("<a id='studentNameLink' target='_blank' href='" + nameLink + "'>"); // Wrap text field in anchor
$(nameTextField).css('color', '#326699'); // Make text blue
$(nameTextField).val(studentName); // Set text field value
Half the people here missunderstood it. The OP would like to have the content/value of the input fields to be hyperlinks instantly and NOT the fields themselves.
It is doable... although it's not an input field but the appearance acts like such one.
Use the following: contenteditable=true
HTML
<div contenteditable=true>
<a id=lnk style=-moz-appearance:textfield href=http://www.google.com>http://www.google.com</a>
</div>
or optionally -webkit-appearance ..depends
JavaScript
var lnk=document.getElementById('lnk');
lnk.addEventListener('click',()=>{
window.location.href = lnk.getAttribute('href');
});

You want someone clicking a textbox to actually be treated as a link click?
Sounds malicious to me but you could bind the focus event via javascript to a window.redirect().
I don't know if I get the question right. As I've understood you want to be able to type in a ...-tag into an input-field. No other tags should be allowed. You can achieve this by using PHP for example:
<!-- HTML-Code -->
<input type="text" name="link" />
// PHP-Code
$link = strip_tags($_POST['link'], 'a'); // Remove all other tags than the <a>-Tag...
Is that what you mean?
Yes, it is possible, but it's not that simple. You need to create div, or other tag you prefer, that will be always floating over your input, using CSS positions, and create anchor inside it.
For example, virtual keyboard img is embedded into input field that way on russian Google page (http://www.google.ru/)
Because of browser-compatibility it's not a simple task.
EDIT: Understood your question a little more. You still need first part of the answer, and you will need to handle keypress event inside your input. When symbol is entered you will need to update your floating div.
So now task is difficult even more. Maybe you should revise your model and not the code.
