As you know, the best way to find the length of a string is by using the strlen() function.
Java has an inbuilt method called length() to find the number of characters of any String. int length(); where length() is a method to find the number of characters and returns the result as an integer.
Java String length method() The Java String class contains a length() method that will return the total number of characters a given String contains. This value includes all blanks, spaces, and other special characters. Every character in the String is counted.
The string length is the number of characters in a string. In the string length '\0,' a character is not counted. In the example shown above, the length of the string str is 6.
You don't need jquery, just use yourstring.length. See reference here and also here.
Update:
To support unicode strings, length need to be computed as following:
[..."𠮷"].length
or create an auxiliary function
function uniLen(s) {
return [...s].length
}
The easiest way:
$('#selector').val().length
jQuery is a JavaScript library.
You don't need to use jQuery to get the length of a string because it is a basic JavaScript string object property.
somestring.length;
HTML
<div class="selector">Text mates</div>
SCRIPT
alert(jQuery('.selector').text().length);
RESULT
10
You don't need to use jquery.
var myString = 'abc';
var n = myString.length;
n will be 3.
A somewhat important distinction is if the element is an input or not. If an input you can use:
$('#selector').val().length;
otherwise if the element is a different html element like a paragraph or list item div etc, you must use
$('#selector').text().length;
