I am currently trying to write a ''web application'' that has a simple
text area inside, in which I want the letters of the
text written to be pointed out.
For example, if I write:
''How old are you? I am 19 years old''
I need a code to tell me how many 'A's and 'Y's and 'D's (and all letters of the alphabet from 0-26) are used in this sentence when I press a button on a HTML/ CSS page.
Could you please tell me what I must write into my .JS file and what I should write into my .HTML file to do this with a click of a button when something is written in the ?
I hope my explanation was detailed enough. Thanks!
Edit (I'm very sorry for the problems I caused) - What I have done so far looks like this:
HTML:
<link rel="stylesheet" type="text/css" href="theme.css">
<meta charset="utf-8">
<script src="test.js" type="text/javascript"></script>
<div class='header'>
Al.Fa.Be
</div>
<div class='yaz'>
<textarea></textarea>
</div>
<div class='description'>
<a href='http://www.google.com'>Ara</a>
</div>
<div class='description2'>
<input id="clickMe" type="button" value="Hesapla" onclick="doFunction();" />
</div>
CSS:
body{
background:white;
}
selection{
background:#CCC;
}
#clickMe{
background:#CCC;
border:1px solid #333;
}
.header{
font-size:70px;
font-weight:bold;
font-family:Arial;
color:#333;
margin-left:580px;
padding-top:200px;
}
textarea{
width:1210px;
height:40px;
color:black;
margin-top:20px;
margin-left:100px;
padding-left:10px;
padding-top:10px;
font-size:18px;
font-family:Arial;
}
.description{
background:#f2f2f2;
padding:6px;
width:50px;
text-align:center;
border:1px solid #ddd;
font-family:Arial;
margin-left:620px;
margin-top:20px;
font-size:14px;
}
.description a{
color:#555;
text-decoration:none;
}
.description2{
background:#f2f2f2;
padding:6px;
width:60px;
text-align:center;
border:1px solid #ddd;
font-family:Arial;
margin-left:750px;
margin-top:-30px;
font-size:14px;
}
.description2 a{
color:#555;
text-decoration:none;
}
.yaz{
color:white;
}
Javascript:
//
Input name. Count number of alphabets a-z
class program
{
public static void main(String[] args)
{
String name = args[0];
int count[] = new int[29];
int i,p;
int n = name.length();
name = name.toUpperCase();
char c;
for (i=0; i<29; i++)
{
count[i] = 0;
}
for (i=0; i<n; i++)
{
c = name.charAt(i);
p = (int) c;
count[p-65]++;
}
for (i=0; i<29 ; i++)
{
if (count[i] >0)
{
System.out.println((char)(i+65) + " occurs " + count[i] + " times");
}
}
}
}
