How can I move text cursor in a text input field?

Thanks the following codes. while in Firefox, you just need to invoke textElement.focus() method.

So here is how to position the caret end the end of a text field/text
area with IE4/5:

<script>
function setCaretToEnd (el) {
  if (el.createTextRange) {
    var v = el.value;
    var r = el.createTextRange();
    r.moveStart(&aposcharacter', v.length);
    r.select();
  }
}
function insertAtEnd (el, txt) {
  el.value += txt;
  setCaretToEnd (el);
}
</script>








       ONCLICK="insertAtEnd (this.form.aText,
this.form.a2ndText.value);"
>




       ONCLICK="insertAtEnd (this.form.aTextArea,
this.form.a3rdText.value);"
>


</body></html></HTML>
