Hi!
About a year ago I was working on a text editor which included highlighting and such, but also offered the functionality to insert BB-code, just like at DaniWeb. The basic idea of this is to retrieve the position of selected text, retrieve the text, embody it with BB-code and then save the changes in the value of the textarea. Here is the function I created:
*** EDIT: Due to the annoying fact that BB-code within the CODE tags is also parsed on DaniWeb, I added forward-slashes to prevent that. Remove them in order for the code to function properly. ***
/*
*
* Function: InsertBBCode
* Parameters:
[0] TXT_Element: The textarea element in which BBCode needs to be inserted
[1] Variable: Contains the variable name of the BBCode
[2] Value: Contains the variable value of the BBCode
* Notes: inserts bbcode into the textarea

function InsertBBCode( TXT_Element, Variable, Value )
{
var Open_Tag = "";
var Close_Tag = "";
switch ( Variable ) {
case "bold" :
Open_Tag = "\[b\]";
Close_Tag = "\[/b\]";
break;
case "underline" :
Open_Tag = "\[u\]";
Close_Tag = "\[/u\]";
break;
case "italic" :
Open_Tag = "\[i\]";
Close_Tag = "\[/i\]";
break;
case "justifyleft" :
Open_Tag = "[align=left]";
Close_Tag = "[/align]";
break;
case "justifycenter" :
Open_Tag = "[align=center]";
Close_Tag = "[/align]";
break;
case "justifyright" :
Open_Tag = "[align=right]";
Close_Tag = "[/align]";
break;
case "insertorderedlist" :
Open_Tag = "[list=1][*]";
Close_Tag = "[/*][/list]";
break;
case "insertunorderedlist" :
Open_Tag = "[list][*]";
Close_Tag = "[/*][/list]";
break;
case "indent" :
Open_Tag = "[indent]";
Close_Tag = "[/indent]";
break;
case "outdent" :
/* Outdent is removing the indent tags, which the user can do by himself. */
break;
case "CreateLink" :
Open_Tag = "\[url=" + Value + "\]";
Close_Tag = "\[/url\]";
break;
case "FontSize" :
Open_Tag = "\[size=" + Value + "\]";
Close_Tag = "\[/size\]";
break;
}
if ( typeof(TXT_Element) != "undefined") {
/* Length of the selection: */
var Length = parseInt(TXT_Element.value.length);
/* Open position of the selection: */
var SelectionStart = TXT_Element.selectionStart;
/* End position of the selection: */
var SelectionEnd = TXT_Element.selectionEnd;
/* Value of the new textarea: */
var NewValueTextArea = "";
/* Updating textarea value: */
NewValueTextArea = TXT_Element.value.substring(0,SelectionStart); // Beginning text
NewValueTextArea += Open_Tag; // Open tag
NewValueTextArea += TXT_Element.value.substring(SelectionStart,SelectionEnd); // Text between tags
NewValueTextArea += Close_Tag; // Close tag
NewValueTextArea += TXT_Element.value.substring(SelectionEnd,Length); // Ending text
/* Updating textarea content: */
TXT_Element.value = NewValueTextArea;
} else {
/* If nothing is supported, put it on the end: */
TXT_Element.value += Open_Tag + Close_Tag;
}
//alert("Value of the hidden input:\n\n" + TXT_Element.value);
/* Focussing element: */
TXT_Element.focus();
}The above function is written in JavaScript, and all the steps are obviously clearly explained. If you have any questions, post a reply!
