Search a String Variable with JavaScript Methods
Write the JavaScript code to search through a string.
Compare JavaScript methods for searching through strings.
Use a JavaScript method to replace a value in a string.
In this intermediate-level project you will write JavaScript code to search through a string variable. You’ll use a variety of JavaScript methods to locate values within a string to determine whether they exist, find their position in the string, or even replace them with other values. The Notepad++ editor and Chrome browser are used to write inline JavaScript code and view the results. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.
Skills you will develop
- JavaScript replace()
- Javascript Methods
- JavaScript search()
- Strings
- Java Syntax
Learn step-by-step
In a video that plays in a split-screen with your work area, your instructor will walk you through these steps:
Declare a JavaScript variable and assign to it a string value, while demonstrating string-handling techniques.
Use the JavaScript includes() method to search through a string to determine whether it contains a string of characters.
Search through a string using the JavaScript search() method with the goal of returning the position of the matching characters or set of characters.
Search through a string with the JavaScript indexOf() method to return the first occurrence of a specific value.
Search through a string with the JavaScript lastIndexOf() method to return the last occurrence of a specific value.
Locate and replace a value in a JavaScript string using the replace() method.
