Does anybody have a cross browser JS function to get selected text

Reply Quote

I am trying to create a cross browser JS function to get selected text ... does anybody have anything better than what I am using?

function GetSelectedText()

{

var retval='';

<%If mozilla Then%>

         sel=ce.GetSelection();
         retval=sel.focusNode.textContent.substr(sel.anchorOffset,sel.focusOffset-sel.anchorOffset);
   <%ElseIf IE Then%>

         sel=ce.GetSelection().createRange();
         retval=sel.htmlText;
   <%End If%>

return retval;

}

Please use the following code:

function getSelectedHTML(){
var rng=null,html="";

      if (document.selection && document.selection.createRange){
        rng=editdoc.selection.createRange();
        html=rng.htmlText||"";
      }else if (window.getSelection){
        rng=editwin.getSelection();

        if (rng.rangeCount > 0 && window.XMLSerializer){
          rng=rng.getRangeAt(0);
          html=new XMLSerializer().serializeToString(rng.cloneContents());
        }
      }
      return html;
    }

Thanks, that really got me started, I have fixed the errors and added a keepHTML parameter so that I can choose whether I want just plain text or not.

function HTMLFieldGetSelectedText(keepHTML)

    {
    var rng=null,retval='';
    var ce=document.getElementById('CE_Editor_ID');

    if(ce&&ce.IsReady)
        {
        if (ce.GetSelection && ce.GetSelection().createRange)
            {
            rng=ce.GetSelection().createRange();
            retval=keepHTML?rng.htmlText||'':rng.text;
            }
        else if (ce.GetSelection)
            {
            rng=ce.GetSelection();

            if (rng.rangeCount > 0 && window.XMLSerializer)
                {
                rng=rng.getRangeAt(0);
                retval=keepHTML?new XMLSerializer().serializeToString(rng.cloneContents()):rng.cloneContents().textContent;;
                }
            }
        }

    return retval;

}
