How to find the single or multiple paragraphs which have the required word or string? Var str = 'Hello world, welcome to the universe.' ĭocument.getElementById('demo').innerHTML = n Occurrences of any Substring or Word can be obtained just by passing it into the code, in the findWord variable, in this case. The code has a while loop to Search the substring or the word and count the number of occurrences 'Is time an illusion created within our minds? Or is it a dimension of the physical universe? Either way,time largely defines the human experience.' In this case, we will use the indexOf() Method in JavaScript to find the number of occurrences of desired word or substring. How to find the number of occurrences of a particular word or a string in a given string or paragraph? Var modifiedStrng = strng.replace(/CREATED/i, 'brainwashed') ĭocument.write('Modified String : ' + modifiedStrng + '') Strng = 'Is time an illusion created within our minds?' ĭocument.write('Original String : ' + strng + '') Var modifiedStrng = strng.replace("created", "brainwashed") ĭocument.write("Modified String : " + modifiedStrng + "") Strng = "Is time an illusion created within our minds?" ĭocument.write("Original String : " + strng + "") We can use the replace() method with either regular expression or string as an argument. We can achieve this by using a Regular Expression that provides us the text replace functionality with its string method: replace() which replaces the specified string with the desired word or substring thereby modifying the original string. The string position is 11 because JavaScript counts the first position of string as 0 How to find a string and replace it with some other string? Strng = "Is time an illusion created within our minds? Or is it a dimension of the physical universe? Either way,time largely defines the human experience." ĭocument.write("Desired String is present at position : " + position) 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. (not yet compatible with optimizeChunkAssets) rules.X.replacements.X.In this article, we will learn how to search and locate the words or substrings in paragraphs or large strings. If set, locations where patterns are matched will have X characters of the source code (before and after) logged for inspection. (condition must be met for at least one compilation)Įxamples: (see rules.X.chunkMatchCount) logAroundPatternMatches - number (new WebpackStringReplacer(Ĭhecked against the number of pattern matches, in all (unignored) chunks/files within the compilation. Const WebpackStringReplacer = require("webpack-string-replacer")
