[Solved] Textarea indent 4 spaces jQuery & Codeigniter

Hi,

I have not tested it, but is should work.
What you need to do is to find the newline and add your startTag to each line.
Because of different character for new line on Windows, Linux and Mac you need to test for all 3.
You will notice I use the \r\n (Windows linebreak) to insure it works on most systems

PHP Code:

function wrapText(elementID, openTag, closeTag) {
    var textArea = $('#' + elementID);
    var len = textArea.val().length;
    var start = textArea[0].selectionStart;
    var end = textArea[0].selectionEnd;
    var selectedText = textArea.val().substring(start, end);
    var replacement = openTag + selectedText + closeTag;

    replacement.replace(/\r\n|\r|\n/g,"\r\n"+openTag);

    textArea.val(textArea.val().substring(0, start) + replacement + textArea.val().substring(end, len));
}

It's only when I click on my button for it I though And I am not after line break

There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!
