Hi all guy!!! I have writing this code but my var word don't count the uppercase letters!!!
HOW TO FIX????
Code:
<!DOCTYPE HTML>
<html>
<head>
<script type="text/javascript">
function alphabet (letter)
{
var returnValueAlphabet = true;
if (letter == "a" || letter == "b" || letter == "c" || letter == "d" || letter == "e" || letter == "f" || letter == "g" || letter == "h" || letter == "i" || letter == "j" || letter == "k" || letter == "l" || letter == "m" || letter == "n" || letter == "o" || letter == "p" ||letter == "q" || letter == "r" || letter == "s" || letter == "t" || letter == "u" || letter == "v" || letter == "w" || letter == "x" || letter == "y" || letter == "z")
{
returnValueAlphabet = false;
}
return returnValueAlphabet;
}
function start ()
{
var len = [];
var count = 0;
var phrase = 0;
var numberWord = 0;
var word = 0;
var arrayPhrase = "Yesterday is history. Tomorrow is a mystery. But today is a gift. For this it is called present."; <------ *UPDATING var arrayPhrase = ["Yesterday is history....ecc"];
*UPDATING ---> ---> ---> ---> ---> ---> ---> ---> ---> ---> ---> ---> ---> ---> ---> ---> --->
for (i = 0; i < arrayPhrase.length; i++)
{
if (arrayPhrase[i] == ".")
{
len[count] = numberWord;
numberWord = 0;
count++;
phrase++;
}
if (!alphabet (arrayPhrase[i]))
{
numberWord++;
word++;
}
}
alert ("Total words =" + " " + word + "\n\n" + "Total phrase =" + " " + phrase + "\n\n" + "Words in the phrase =" + " " + len.join (", "));
}
</script>
</head>
<body>
<button type="button" onclick="start ()">TRY ME</button>
</body>
</html>
*UPDATING, I reread my problem and call that the stringh "Yesterday...... ecc" is insert into a array!!!! And now all programs don t work....
<!DOCTYPE HTML>
<html>
<head>
<script type="text/javascript">
function alphabet (letter) {
var returnValueAlphabet = true;
letter =letter.toLowerCase();
if (letter == "a" || letter == "b" || letter == "c" || letter == "d" || letter == "e" || letter == "f" || letter == "g" || letter == "h" || letter == "i" || letter == "j" || letter == "k" || letter == "l" || letter == "m" || letter == "n" || letter == "o" || letter == "p" ||letter == "q" || letter == "r" || letter == "s" || letter == "t" || letter == "u" || letter == "v" || letter == "w" || letter == "x" || letter == "y" || letter == "z")
{
returnValueAlphabet = false;
}
return returnValueAlphabet;
}
function start ()
{
var len = [];
var count = 0;
var phrase = 0;
var numberWord = 0;
var word = 0;
var arrayPhrase = "Yesterday is history. Tomorrow is a mystery. But today is a gift. For this it is called present.";
// <------ *UPDATING var arrayPhrase = ["Yesterday is history....ecc"];
// *UPDATING ---> ---> ---> ---> ---> ---> ---> ---> ---> ---> ---> ---> ---> ---> ---> ---> --->
for (i = 0; i < arrayPhrase.length; i++)
{
if (arrayPhrase.charAt(i) == ".")
{
len[count] = numberWord;
numberWord = 0;
count++;
phrase++;
}
if (!alphabet (arrayPhrase.charAt(i)))
{
numberWord++;
word++;
}
}
alert ("Total words =" + " " + word + "\n\n" + "Total phrase =" + " " + phrase + "\n\n" + "Words in the phrase =" + " " + len.join (", "));
}
</script>
</head>
<body>
<button type="button" onclick="start ()">TRY ME</button>
</body>
</html>
Of course, there is no reason at all to even need that alphabet function.
Code:
function start ()
{
var arrayPhrase = "Yesterday is history. Tomorrow is a mystery. But today is a gift. For this it is called present.";
var phrases = arrayPhrase.split(".");
var wordsPerPhrase = [ ];
var totalWords = 0;
for ( var p = 0; p < phrases.length - 1; ++p )
{
var words = phrases[p].replace(/^\s+/,"").replace(/\s+$/,"").split(" ");
wordsPerPhrase[p] = words.length;
totalWords += words.length;
}
alert ( "Total words = " + totalWords + "\n\n"
+ "Total phrases = " + phrases.length + "\n\n"
+ "Words in each phrase = " + wordsPerPhrase.join(", ")
);
}
start();

I don t see anyone of your method Pedant!!! xD
And your last comment!! It's a mystery for me \s+\... I don't think it's a code for beginner
However thanks for all example, I'll remember for the next time!!!!

Hi guy... This code don't work, my anti-bug crah when arrive at this part:
if (arrayPhrase.charAt(i) == ".")
Don't know how to works with the array!!!
function start ()
{
var arrayPhrase = "Yesterday is history. Tomorrow is a mystery. But today is a gift. For this it is called present.";
// split breaks a sting into an ARRAY of strings, all broken
// apart on the character (or regular expression) you give:
var phrases = arrayPhrase.split(".");
// so now we have each sentence (that used to end in a period)
// in a separate element of the array named phrases
var wordsPerPhrase = [ ];
var totalWords = 0;
// loop through all the phrases/sentences in the phrases array
// notice that we do *NOT* process the last element of the array
// because it will be the blank string after the last period
for ( var p = 0; p < phrases.length - 1; ++p )
{
// this is the trickiest part, so let's break it down in pieces:
// phrases[p] :: get one phrase from the array
// .replace(/^\s+/,"") :: replace all *leading* spaces with nothing
// .replace(/\s+$/,"") :: replace all *trailing* spaces with nothing
// (in other words, trim the spaces off both ends
// .split(" "); :: split the phrase into words, just as we split into phrases
var words = phrases[p].replace(/^\s+/,"").replace(/\s+$/,"").split(" ");
// so now we have an array named words...and it has as many elements
// as there are words in the phrase!
// put the count of words in to proper element of the wordsPerPhrase array
wordsPerPhrase[p] = words.length;
// and bump the count of the total number of words
totalWords += words.length;
}
// and then just show the final numbers:
// I corrected the value for Total Phrases from my prior post
alert ( "Total words = " + totalWords + "\n\n"
+ "Total phrases = " + (phrases.length-1) + "\n\n"
+ "Words in each phrase = " + wordsPerPhrase.join(", ")
);
}

But in my inizial post i write arrayPhrase = ["Yesterday.....];
This is an array!!! I would use an array!!!
That would then be an array containing ONE element which is a string. Then arrayPhrase[0] will be the entire string and arrayPhrase[1] will be beyond the end of the array.
Using array notation to reference characters in a string has been recently introduced as an alternative to using charAt but there are still lots of browsers in use that don't support it.

An ok!!!! But however if I use charAt, still don't work !!!!!!!!!!!
So what does your code look like now. Also are there any error messages on the error console?
No error in console, but I find error!!!
When I write array = ["Yehxcwj ecc...."]
the programs read this how to one element of array, so when start cicle for (i = 0; i < array.length; i++), the programs execute only one for because the length of array is 0. How to fix this problem!?!?! Beacause my problem ask: " Is stored in an array a text of char. Print the numbers of word, phrase and word for phrase!!!".
If I use an simple var the progrma work perfectly
... Then arrayPhrase[0] will be the entire string ...
So just do
Code:
var text = arrayPhrase[0];
and then replace all uses of arrayPhrase after that point with text.
But I strongly suspect you are misreading the homework assignment. Or the instructor just used the wrong words. Maybe you should copy the assignment here *VERBATIM*.
