I have a simple text area box with php in the box on refresh:
<textarea><?php //php in here ?></textarea>
At the moment, the php is very long and when it does echo out the value the box should be there is a lot of white space in between. i think this is because of the large amount of php (not shown). is there a way to use the trim() or a css attribute that aligns the text to the left?
Anything between two PHP is extracted by the compiler and the result of the PHP is inserted at that point. No new lines or anything within the tags is outputted. You are also allowed to use new lines within the tags.
Example:
<textarea>
<?php
for($i=0;$i<10;$i++)
{
echo("hello");
}
?>
</textarea>

I am using html textarea to simulate a command prompt. On typing a command command (e.g. ipconfig) and hitting Enter key, the command output gets appended to to the text. To read the output I have added aria-live="polite" attribute to the textarea which works fine with NVDA screen reader. However, JAWS on IE, starts reading from the top every time a command is entered. How do I make it read only the newly appended text like NVDA does?
So far I have tried aria-relevant="additions", role=log, role=alert attributes but nothing seems to work.
enter code here
<textarea id="commandPrompt" aria-live="polite"
rows="5" cols="45" wrap="off" spellcheck="false">
</textarea>
IN theory, you should be able to define precisely what should be read using aria-relevant and aria-atomic.
Unfortunately, Jaws doesn't follow standards very well. These two attributes are known not to always work as expected with Jaws, depending on the browser used, the element to which they are applied, etc.
This is probably not the answer you wanted to have, but if Jaws doesn't do what you expect, the only solution is most likely to put the text to be spoken in another element.
In a div or span you are much more mikely to have the expected behavior.
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 have a micropost feature and was testing the way it formats text that has been posted when displaying back to the user.
I pasted the following text like this:
and this was displayed back to me:
I'm using "simple_format h(content)". When I remove the helper the text is displayed with out a new line from the word "In". It displays as one big paragraph so I assume the helper is working but for some reason my double new lines are being ignored.
Any idea what is going on? Am I missing something?
By seeing it back, do you mean inside a textarea, or on the page? If it's on the page, all whitespace is compressed to one space each. If it's the latter, simply use the css rule:
white-space:pre;
On the proper selector.
However, if it is in a textarea (which preserves whitespace by default), there must be something stripping the extra space when you save it into the database. You might want to debug down your stack in the model & controller, to see where this might be happening. I have to admit i haven't used the the simple_format method.
Thanks to chrome developer tools as per usual. I realised that each text separated by 2 new lines were wrapped with p tags so I just added a bottom margin of 5px using css to p. Works perfectly.
