# BB-kod (ändra markerad text) ?

## #1 — Guldstrand, 2007-11-11T04:25Z

Är tacksam ifall någon kunde hjälpa mig att ändra följande kod så att det fungerar att ändra **markerad** text.

Har förstått att man ska använda sig av "insertAroundCursor", men förstår inte riktigt hur jag ska ändra koden nedan.

```
<script language=javascript>
function insertAtCursor(myField, myValue) {
//IE support
  if (document.selection) {
    myField.focus();
    sel = document.selection.createRange();
    sel.text = myValue;
  }

//MOZILLA/NETSCAPE support
  else if (myField.selectionStart || myField.selectionStart == '0') {
    var startPos = myField.selectionStart;
    var endPos = myField.selectionEnd;
    myField.value = myField.value.substring(0, startPos) + myValue + myField.value.substring(endPos, myField.value.length);
    myField.selectionEnd = startPos + myValue.length;
  } else {
    myField.value += myValue;
  }
  myField.focus();
}

// calling the function
function SmileIT(smile,form,text){
    insertAtCursor(document.forms[form].elements[text], smile)
}

function BBTag(tag,s,text,form){
  var df  = document.forms[form].elements[s];
  var ele = document.forms[form].elements[text];
  var tval;
  var ttag;
  switch(tag) {
    case '[quote]':
            tval = "QUOTE ";
            ttag  = "[/quote]";
            if(df.value == "QUOTE ") {
              tval = "QUOTE*";
              ttag  = "[quote]";
            }
            break;
    case '[img]':
            tval = "IMG ";
            ttag = "[/img]";
            if(df.value == "IMG ") {
              tval = "IMG*";
              ttag  = "[img]";
            }
            break;

    case '[url]':
            tval = "URL ";
            ttag = "[/url]";
            if(df.value == "URL ") {
              tval = "URL*";
              ttag  = "[url]";
            }
            break;

    case '[*]':
            tval= "List ";
                        if(df.value == "List ") ttag  = "[*]";
            break;

            insertAtCursor(ele, tag);
            df.elements[s].value = tval;
            break;

    case '[hr]':
                        tval= "Hr ";
                        if(df.value =="HR "){
                            ttag="[HR]";
            }
                        insertAtCursor(ele,tag);
            df.elements[s].value=tval;
            break;

    case '[center]':    tval= "Center";
            ttag= "[/center]";
            if(df.value == "Center "){
                    tval = "Center* ";
                 ttag="[center]";
                }
                    
                   
            break;            

    case '[b]':
            tval = "B ";
            ttag = "[/b]";
            if(df.value == "B ") {
              tval = "B*";
              ttag  = "[b]";
            }
            break;

    case '[i]':
            tval = "I ";
            ttag = "[/i]";
            if(df.value == "I ") {
              tval = "I*";
              ttag  = "[i]";
            }
            break;

    case '[u]':
            tval = "U ";
            ttag = "[/u]";
            if(df.value == "U ") {
              tval = "U*";
              ttag  = "[u]";
            }
            break;

    case '[s]':
            tval = "S ";
            ttag = "[/s]";
            if(df.value == "S ") {
              tval = "S*";
              ttag  = "[s]";
            }
            break;
  }
  if(tval!="") df.value = tval;
  if(ttag!="") insertAtCursor(ele, ttag);
}
