word count fuormula javscript code example
Example 1: count word and space in text javascript
<html>
<body>
<script>
function countWords(str) {
str = str.replace(/(^\s*)|(\s*$)/gi,"");
str = str.replace(/[ ]{2,}/gi," ");
str = str.replace(/\n /,"\n");
return str.split(' ').length;
}
document.write(countWords(" Tutorix is one of the best E-learning platforms"));
</script>
</body>
</html>
Example 2: Count Total Amount Of Specific Word In a String JavaScript
Here are two methods (Scroll down please here!) to find the total number of occurrence match
words in the string.
The first function allows you to give a query as input.
The second one uses the .match function of JavaScript.
Both introduced methods are resistant for any chars and
independent of splitter and separator like " " or ",".
str1 is your query
str1 = "fake";
str2 is the whole string:
var inputString = "fakefakefakegg fake 00f0 221 Hello wo fake misinfo
fakeddfakefake , wo 431,,asd misinfo misinfo co wo fake sosis bandari
mikhori?, fake fake fake ";
Method 1 : use .indexOf or .search function of JavaScript
(advantage you can give input)
function CountTotalAmountOfSpecificWordInaString(str1, str2)
{
let next = 0;
let findedword = 0;
do {
var n = str2.indexOf(str1, next);
findedword = findedword +1;
next = n + str1.length;
}while (n>=0);
console.log("total finded word :" , findedword - 1 );
return findedword;
}
Method 2 : use .match function of JavaScript:
function CountTotalAmountOfMachedWordInaString(str2) {
let machedWord = 0;
machedWord = str2.match(/fake/g).length;
console.log("total finded mached :" , machedWord);
return machedWord;
}
call the functions (Inputs):
CountTotalAmountOfSpecificWordInaString("fake" , "fake fakefakegg fake 00f0 221 Hello wo fake rld fakefakefake , wo lklsak dalkkfakelasd co wo fake , fake fake fake" );
CountTotalAmountOfMachedWordInaString("sosis bandarie fake khiyarshour sosis , droud bar fake to sosis3");
