How To Wrap A Selected Text In A TextArea

Jul 27, 2011

I searched about this problem over Internet and found the same result many times, I found this example on stackoverflow [URL] but this example didn't work in my project; I am making a toolbar with buttons that insert HTML tags around the selected text in a <textarea>, this exemple didn't work because when the user click on a button the selected text won't be selected anymore because <textarea> loses focus and selected text will be unselected, I am targeting Firefox and compatible browsers so you don't need to give me the IE code; jQuery codes are accepted;

Highlight HTML Code In Textarea

Aug 4, 2005

I have a PHP/MySQL-based content management system that alows one to edit pages of a website through form textareas. I was wondering if it is possible to change the appearance of HTML tags inside the textarea so the HTML markup looks different (e.g., in grey), making it easier to quickly find and edit the 'real' content without messing up the tag (like accidentally deleting a '>' character).

Put IFRAME Source Code Into Textarea

Jun 27, 2006

I would you grab the source code from an IFRAME and display it in a textarea?

I'm trying to create a sort of preview page that both shows a rendered page, then shows the source code next to it.

[edit]: I'm thinking that using OnLoad JS event in the HTML body tag would allow this to work. The page loads, the OnLoad event calls a JS function that pulls the innerHTML from the IFRAME and inserts it into the textarea.

Showing Javascript Code Outputs In Textarea?

Mar 3, 2006

I'm having a problem showing the output of this code in the textfield.

<html>
<head>

<script language="JavaScript">
<!--
var url = document.URL;
-->
</script>

</head>
<body>

<textarea style="overflow: auto;" rows="1" cols="70" wrap="off" readonly>
<script language="JavaScript">document.write(url);</script>
</textarea>

<br><br>

Create A Small DHTML Code That Created A Unordered List Of Input Forms Dependent On The Number Selected From The Select Dropdown Menu

Oct 21, 2011

I wanted to create a small DHTML code that created a unordered list of input forms dependent on the number selected from the select dropdown menu. Problem is that it doesn't seem to want to generate the list. I think the variables are within the scope of the function too, and I didn't get an errors from the javascript console when using firebug. The script itself runs, I tested it when I used the old standby alert(); to see if the script was active. Here's the code:

Hex To An Image Lookup - Convert The Hex Code Into An Image Containing The Selected Colour?

May 1, 2009

how I can get this lookup to work..:?I'm using a app that uploads an image and returns a hex code in a 3x3 grid. (See here: http://jrm.cc/color-palette-generator) I want to take this one stage further and have a code that will then take the Hex code and look up a field in an sql database containing hex codes. Then convert the hex code into an image containing the selected colour. For example;

User uploads image of the sky

App returns hex codes of sky

App then needs to look in a field database of images on server and finds image/s with similar hex value

App then returns images in replace of the hex code (i.e blue water, swimming pool, blue coloured hat etc etc)
