Is the caret at the start of the text input?

@PittimannMay 21.2004 — #Hi!

Play with this, if you like:

[code=php]<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
 <html>
 <head>
 <title>Untitled</title>
 <script language="JavaScript" type="text/javascript">
 <!--
 var defaultText1="There is a selection in the text field."
 var defaultText2="Cursor <b>is not</b> at the beginning of the text field."
 var pos;
 var begin;
 var isSel;
 function checkCursor(where) {
 isSel=0;
 begin=0;
 if (document.selection) {//IE stuff
 where.focus();
 sel = document.selection.createRange();
 if(sel.text==""){
 sel.text='µµµ';//insert nonsense at cursor position for IE
 dummy = where.createTextRange();
 dummy.findText('µµµ');
 dummy.select();
 pos=where.value.indexOf('µµµ');//get position of nonsense's begin
 begin=pos;
 document.selection.clear();//delete nonsense
 where.focus();
 }
 if(sel.text!=""){
 isSel=1;
 }
 }//end IE stuff
 else if (where.selectionStart || where.selectionStart == '0') {//Mozilla stuff
 begin = where.selectionStart;
 var end = where.selectionEnd;
 if(end!=begin){
 isSel=1;
 }
 }//end Mozilla stuff
 if(isSel==0&&begin==0){
 document.getElementById('posi').innerHTML='Cursor <b>is</b> at the beginning of the text field';//action to take if cursor is at start pos
 }
 else if(isSel==1){
 document.getElementById('posi').innerHTML=defaultText1;//action to take if text is selected
 }
 else{
 document.getElementById('posi').innerHTML=defaultText2;//action to take if cursor is not at start pos and no text is selected
 }
 }
 //-->
 </script>
 </head>
 <body onload="document.getElementById('posi').innerHTML=defaultText2;">
 <form name=frm>
 <input name="txt" value="abcdefgdefghijklmno" onclick="checkCursor(this);" onkeyup="checkCursor(this);"><br>
 </form>
 <span id="posi"></span>
 </body>
 </html>[/code]
