Remove first 3 characters from title

I need to remove first 3 characters from title. I used:

$(".layered_subtitle").each(function() {
var text = $(this).text();
text = text.replace('06.', '');
$(this).text(text);

I have dynamicly loaded titles with numbering:

01.title

02.title

03.title ..

How to to separate characters to be removed?

You could use substring method like this:

$(".layered_subtitle").each(function() {
    var text = $(this).text();
    if(text && text.length > 3){
        text = text.substring(3)
        $(this).text(text);
    }
});

If you need to do this on ajax request success:

function removeChars(){
   $(".layered_subtitle").each(function() {
       var text = $(this).text();
       if(text && text.length > 3){
           text = text.substring(3)
           $(this).text(text);
       }
   });
}
var serializedData = {};//Fill data
$.ajax({
    url: "url",
    type: "post",//post or get
    data: serializedData,
    // callback handler that will be called on success
    success: function (){
        //Add here logic where you update DOM
        //(in your case add divs with layered_subtitle class)
        //Now there is new data on page where we need to remove chars
        removeChars();
    }
});

If you don't know the exact position of separator (point) you must find it:

var newText = oldText.substr(oldText.indexOf('.') + 1);

Or, if you can find many digits or a space char after separator you need to use a regex:

var newText = oldText.replace(/^\d+\.\s*/, "");

Both would work.

You can remove the first three characters, if the title is at least three characters:

if (text.length >= 3) text = test.substring(3);

You can use a regular expression to only remove the numbers if it matches the format "nn.xxxx":

 text = text.replace(/^\d\d\./, '');

The answers so far are all right, but i think you should do it differently for future use. Maybe your count will extend, so just search for the first occurence of "." and then cut the string there.

text = text.substring(text.indexOf(".")+1);

Try this

text = text.substring(3)

instead of 

text = text.replace('06.', '');

Try like this

text = text.substr(3);
alert(text);
$(this).text(text);

You can use this (shortest of the slice/substring/substr-related JavaScript functions which are effectively the same if only using the first argument with a positive integer):

text = text.slice(3);

Just use javascript substring :

text = text.substring(3);
