In this article we will show you the solution of how to remove last character from string in jQuery, the desire to trim a few characters from a string may arise occasionally when working using strings in javascript.
However, as strings in javascript are immutable, this cannot be done.
As a result, in order to delete a character from a string, a new string must be created.
For this, there are several methods that we will learn about in this article, including substring(), slice(), substr(), and replace().
Using the javascript substring() technique, we may remove the last character from a string by extracting and returning the desired portion of the string.
Generally speaking, a starting index and ending index are the two parameters required by the substring() method.
So it returns a string between these indices (the indices provided are inclusive).
If only one index is supplied to the substring() method, it's going to be treated as that of the starting index, and the substring will be produced beginning from the given index through the final index.
This approach has an O(n) time complexity, where n seems to be the length of a substring.

<html lang="en">
<head>

<script>
$(document).ready(function(){
$("a").click(function(){
var fid = $(this).attr("href");
var itemId = fid.substring(1, fid.length);
alert("The ID of the linked image is - " + itemId);
});

- The <script> tag was then added. The script tag also includes the javascript google API run or an explanation of the code or file we used.
