<script>
   function removeSpaces() {
      var textInput = insertText.value;
      var textInput = textInput.replace(/\s{2,}/g, " ");
      insertText.value = textInput;
   }
</script>
<input type="text" id="insertText" value="containin extra space">
<button onclick="removeSpaces()">ok</button>
</body>
</html>
