How can i count the number of characters in a textbox using jquery?
$("#id").val().length < 3
just counts upto 3 character spaces but not the number of characters
This question is related to
jquery
For length including white-space:
$("#id").val().length
For length without white-space:
$("#id").val().replace(/ /g,'').length
For removing only beginning and trailing white-space:
$.trim($("#test").val()).length
For example, the string " t e s t " would evaluate as:
//" t e s t "
$("#id").val();
//Example 1
$("#id").val().length; //Returns 9
//Example 2
$("#id").val().replace(/ /g,'').length; //Returns 4
//Example 3
$.trim($("#test").val()).length; //Returns 7
Here is a demo using all of them.
Use .length to count number of characters, and $.trim() function to remove spaces, and replace(/ /g,'') to replace multiple spaces with just one. Here is an example:
var str = " Hel lo ";
console.log(str.length);
console.log($.trim(str).length);
console.log(str.replace(/ /g,'').length);
Output:
20
7
5
