Word And Character counter JS

When you  have a text area field where you need to provide information about the word count when the user enters some text in the field. Length of the field is supposed to be 50 Characters. Initially it would show 50 characters left.

 Only 50 characters allowed!
characters left 

<SCRIPT LANGUAGE="JavaScript">  function CountLeft(field, count, max) {  if (field.value.length > max)  field.value = field.value.substring(0, max);  else  count.value = max - field.value.length;  }  </script>   <center>  <form name=sample action="">  Only 50 characters  allowed!</br>  <textarea rows="15" name="text" cols="45"   onKeyDown="CountLeft(this.form.text,this.form.left,50);"  onKeyUp="CountLeft(this.form.text,this.form.left,50);"></textarea>  <input readonly type="text" name="left" size=3 maxlength=3  value="50"> characters left</font>  </form>  </center>

Counting the number of words in a  text area is quite simple with JavaScript. The idea is to count the number of spaces and use this to calculate the number of words. The following example illustrates the script.

Word Count:

<script> function cnt(w,x){ var y=w.value; var r = 0; a=y.replace(/\s/g,' '); a=a.split(' '); for (z=0; z<a.length; z++) {if (a[z].length > 0) r++;} x.value=r; } </script> <form name="myform"> <textarea rows="15" name="w" cols="45" onkeyup="cnt(this,document.myform.c)"></textarea> <br />Word Count: <input type="text" name="c" value="0" size="5" onkeyup="cnt(document.myform.w,this)" /> </form>
