Hello, I need help with the following function Please:
function saveCaret(elem)
{
if( elem.isTextEdit )
{
elem.caretPos = document.selection.createRange();
}
}
var selectionStartChar
function getCaretPos(elem)
{
if ( elem.isTextEdit && elem.caretPos )
{
var orig = elem.value;
alert (orig);
var bookmark = "~";
var caretPos = elem.caretPos;
caretPos.text = bookmark;
selectionStartChar = elem.value.search( bookmark );
window.status = "Caret is at character " + selectionStartChar;
//window.document.writeln ("Caret is at character " + selectionStartChar);
alert ("Users selection starts at char " + selectionStartChar + " (this is the selection we want to move)" );
elem.value = orig;
}
}
it gets called:
<textarea name="ta1" rows="13" cols="60" onSelect="saveCaret(this);">
<input name="btn" type="button" onclick="getCaretPos(ta1)" value="Move Selected Text">
What I am trying to achieve is to hold the 'selected value' at the same time as detecting the char position of the strat of the user selection. By the time it gets into the second function, to the line: alert (orig); my selection has been lost - I still get the char position I am looking for
Thank you in advance
Here is the complete cut n paste code .html. I have achieved some usefull functionality, please copy n run the page. My objective: there are two text areas. Each area has section headers EG:Issues (it will become clear if you run the page) what I am trying to do is: A user selects some text form a section, when they press the move text button, the text will be copied into the same section in the above textarea, (please dont let the length of the code put you off running it, i am not a js techo - i'm sure a techo will spot my error easily - alerts walk you thru what I have working, 95% is working!!) Here is what I have working. OnSelect of the second text area a function runs to createRange. Then on click of the moveText button four function run to detect the char positions of the sections, the first char of the user selected text string and what section it came from. When the last function runs to move the text - All of it moves, please help me - it would be hugely appreciated.
