How to change text input name with radio buttons?

• Here is the text input box: <input type="text" name="english" onkeyup="transcrire()" id="pfc_words" title="<?php echo _pfc("Enter your message here"); ?>" maxlength="<?php echo $max_text_len; ?>"/> I have the following radio buttons: <input type="radio" name="language" value="" checked onClick="french();"/><label for="language">French </label> <input type="radio" name="language" value="" onClick="english();"/> <label for="language">English </label> i need a function to change the name of the text input "english" depending on the radio button selected. if the first radio button is selected i want the text input name set to "french" and if the second radio button is selected i want text input name set to "english".

• Answer:

  <input type="text" name="english" id="pfc_words"... <input type="radio" name="language" checked onClick="setInputName('French')"/> <script type="text/javascript"> function setInputName(name) { var inputElement = document.getElementById('pfc_words'); inputElement.name = name; } </script>
