    Question General JS question: Insert text at caret position?

    General JS question: Insert text at caret position?


    Hi Everyone,

    Perhaps unrelated to Ext, I was hopeful that someone had a snippet lying around that they wouldn't mind sharing. Javascript, is not my forte!

    I have a textarea caret position (as integer, say 15). And would like to insert text at that position.

    Are there cross-browser solutions at doing so?

    Thanks always.
    Alex

    Thanks for the hint, that snippet seems to require that the text area in which the text is being inserted has focus to work. What I need, is an ability to insert text at position X for example (which may not be where the caret is positioned in the given text area).

    ex:

    <textarea id='test'>abc<textarea>

    with something like

    insertAt( $('test'), 1, '111' );

    adjusts the text to

    a111bc


    in the text area.

    So you're just doing string manipulation on the value then? Nothing special needed, just manipulate the string!

    NM got it! Thanks

    Code:
    function moveCursor( obj, pos ){
    	if( obj.createTextRange ){ 
            var range = obj.createTextRange(); 
            range.move("character", pos); 
            range.select(); 
        } else if( obj.selectionStart ){ 
            obj.focus(); 
            obj.setSelectionRange(pos, pos); 
        } 
    }
