I did to some extant and it replacing for first space not for all, I think I need to use .each function of Jquery, I have used .each function but I didn't get the result see this

HTML :

Title : <input type="text" id="title"><br/>
Keyword : <input type="text" id="keyword">

Jquery:

$('#title').keyup(function() {
    var replaceSpace = $(this).val(); 

        var result = replaceSpace.replace(" ", ";");

        $("#keyword").val(result);

});

Thanks.

Answer 1

var result = replaceSpace.replace(/ /g, ";");

Here, / /g is a regex (regular expression). The flag g means global. It causes all matches to be replaced.
