Beregne antal ord og antal punktum.

Hej,
Her har du en simpel udgave:
Pladser følgende i Head delen af den html side:
<script type="text/javascript">
function countit(){
var formcontent=document.wordcount.wordcount2.value
formcontent=formcontent.split(" ")
document.wordcount.wordcount3.value=formcontent.length
}
</script>

Pladcere følgende i Body delen
<form name="wordcount">
<textarea rows="12" name="wordcount2" cols="38" wrap="virtual"></textarea><br>
<input type="button" value="Calculate Words" onClick="countit()"> <input type="text" name="wordcount3" size="20">
</form>

Og lidt indviklet udgave:
Pladser følgende i Head delen af den html side:
<script type="text/javascript">
function CountWords(this_field, show_word_count, show_char_count){
if (show_word_count===undefined){show_word_count=true;} //show is default
if (show_char_count===undefined){show_char_count=false;} //noshow is deft
el=document.getElementById(this_field);
char_count=el.value.length;          // very crude measure
fullStr=el.value+" "; // add space delimiter to end of text
initial_whitespace_rExp= /^[^A-Za-z0-9]+/gi; //use for complex whitespace
left_trimmedStr=fullStr.replace(initial_whitespace_rExp, " ");
non_alphanumerics_rExp=/[^A-Za-z0-9]+/gi;  // and for delimiters
cleanedStr=left_trimmedStr.replace(non_alphanumerics_rExp, " ");
splitString=cleanedStr.split(" ");word_count=splitString.length -1;
if (fullStr.length <2){word_count=0;}
if (word_count===1){wordOrWords=" word";}else{wordOrWords=" words";}
if (char_count===1){charOrChars=" character";}else{charOrChars=" characters";}
if (show_word_count && show_char_count){
  msg="Word Count:\n"+" "+word_count+wordOrWords+"\n";
  msg += " "+char_count+charOrChars;window.alert(msg);
  } else{
  if (show_word_count){alert("Word Count:  "+word_count+wordOrWords);}
  else{
      if (show_char_count){
        window.alert("Character Count:  "+char_count+charOrChars);}
      }
  }
return word_count;
}
</script>
Pladcere følgende i Body delen
<form name="wordcount">
<textarea id="w_in" cols="55" rows="8"></textarea>
<button onclick="CountWords('w_in');return false;">Count The Words Now!
</button>
</form>
Jeg håber hjælper. Funktionerne udregner antal ord i en sætning!

Tak for svaret, dog er det java jeg programmerer i og ikke javascript :) Så det er ikke til så megen nytte, desværre.

aaben filen med en BufferedReader omkring en FileReader
en while loekke som laeser linierne ind med readLine
tael antal punktummer i linien med en for loekke
split linien i ord med split funktionen (som tager regex udtryk)

Her ahr du java udgaven!!!
