This is how you might go about using jQuery to remove string from string so to speak. The example below will hopefully clarify what I mean. It uses jQuery.grep() which is a really cool search function – It’s kind of a PHP substring equivalent… kind of anyways. As always just copy, paste, run using Firebug to test out and experiment.

(function($) {
var myFruits = "Apples, Bananas, Mangos, Blackberries, Oranges";
myFruits = myFruits.replace(/bMangos(, |$)/gi, "");
 
var myFruits = "Apples, Bananas, Mangos, Blackberries, Oranges";
var result = $.grep(myFruits.split(', '), function(v) { return v != "Mangos"; }).join(', ');
console.log(result);
 
function filterOut(my_str, t) { //string, term
  return $.grep(my_str.split(', '), function(v) { return v != t; }).join(', ');
}
})(jQuery);

//output: Apples, Bananas, Blackberries, Oranges

Frequently Asked Questions (FAQs) about jQuery String Manipulation

How can I remove a specific character from a string using jQuery?

To remove a specific character from a string in jQuery, you can use the replace() method. This method searches a string for a specified value, or a regular expression, and returns a new string where the specified values are replaced. Here is an example:

var str = "Hello, World!";
str = str.replace(",", "");
In this example, the comma is removed from the string.

Can I remove multiple instances of a character from a string in jQuery?

Yes, you can remove multiple instances of a character from a string in jQuery. You can use the global search flag (g) in the replace() method to replace all occurrences of a character. Here is an example:

var str = "Hello, World, Hello!";
str = str.replace(/,/g, "");
In this example, all commas are removed from the string.

How can I remove a substring from a string in jQuery?

To remove a substring from a string in jQuery, you can use the replace() method. You just need to specify the substring you want to remove as the first argument of the replace() method. Here is an example:

var str = "Hello, World!";
str = str.replace("World", "");
In this example, the substring “World” is removed from the string.

Can I remove a substring from a string case-insensitively in jQuery?

Yes, you can remove a substring from a string case-insensitively in jQuery. You can use the replace() method with a regular expression and the case-insensitive flag (i). Here is an example:

var str = "Hello, World!";
str = str.replace(/world/i, "");
In this example, the substring “World” is removed from the string, regardless of its case.

How can I remove the first character from a string in jQuery?

To remove the first character from a string in jQuery, you can use the substring() method. This method extracts the characters from a string, between two specified indices, and returns the new sub string. Here is an example:

var str = "Hello, World!";
str = str.substring(1);
In this example, the first character of the string is removed.

How can I remove the last character from a string in jQuery?

To remove the last character from a string in jQuery, you can use the slice() method. This method extracts a part of a string and returns the extracted part in a new string. Here is an example:

var str = "Hello, World!";
str = str.slice(0, -1);
In this example, the last character of the string is removed.

Can I remove a character at a specific position from a string in jQuery?

Yes, you can remove a character at a specific position from a string in jQuery. You can use the slice() method twice to achieve this. Here is an example:

var str = "Hello, World!";
str = str.slice(0, 5) + str.slice(6);
In this example, the character at the 6th position of the string is removed.

How can I remove all spaces from a string in jQuery?

To remove all spaces from a string in jQuery, you can use the replace() method with a regular expression that matches all spaces. Here is an example:

var str = "Hello, World!";
str = str.replace(/\s/g, "");
In this example, all spaces are removed from the string.

Can I remove all non-alphanumeric characters from a string in jQuery?

Yes, you can remove all non-alphanumeric characters from a string in jQuery. You can use the replace() method with a regular expression that matches all non-alphanumeric characters. Here is an example:

var str = "Hello, World!";
str = str.replace(/\W/g, "");
In this example, all non-alphanumeric characters are removed from the string.

How can I remove a string from the end of another string in jQuery?

To remove a string from the end of another string in jQuery, you can use the replace() method with a regular expression that matches the string at the end of the string. Here is an example:

var str = "Hello, World!";
str = str.replace(/World!$/, "");
In this example, the string “World!” is removed from the end of the string.
