We can use the search() method with either a regular expression or string as an argument. This uses an expression to search for a match and returns the starting position of the desired word or substring. We can achieve this by using a Regular Expression which provides us the text search functionality with its string method: search(). How to find a position of a particular word or a substring in the given string? Var incStr = strng.includes("human", 38) Strng = 'Either way, time largely defines the human experience.' Ĭase 2 - Starting Point of search is after ‘h’ in the word “human” Strng = "Either way, time largely defines the human experience." ĭocument.write("Is 'human' present in the string? : " + incStr) Ĭase 1 - Starting Point of the search is before ‘h’ in the word “human” Note: includes() method is not supported in IE11 Also, it has got the flexibility to identify the starting position of the search. If the word or substring is present in the given string, the includes() method returns true otherwise, it returns false. In this case, we will use the includes() method which determines whether a string contains the specified word or a substring. How to find if a word or a substring is present in the given string? How to find the single or multiple paragraphs which have the required word or string.How to find the number of occurrences of a particular word or a string in a given string or paragraph.How to find a string and replace it with some other string.How to find a position of a particular word or a string in the given string.How to find if a word or a substring is present in the given string.We have a couple of scenarios which we are going to look into to achieve it. Sometimes, we come across a requirement where we need to find the substrings in a paragraph. We will achieve this by using both, JavaScript and jQuery. In this article, we will learn how to search and locate the words or substrings in paragraphs or large strings.
