<p class="Articlelist_txts_p">Detailed explanation of JavaScript string replacement method and FAQ
This article will explore two ways to replace string characters in JavaScript: internal JavaScript code and internal HTML for web pages.
Replace string inside JavaScript code
The most direct way is to use the replace() method:
str = str.replace("find","replace");
This method replaces only the first match. To replace all matches, use a regular expression and add the global flag g:
str = str.replace(/fi</p>

This in JavaScript usually refers to an object that "owns" the method, but it depends on how the function is called.
When there is no current object, this refers to the global object. In a web browser, it is represented by window.
When calling a function, this maintains the global object; but when calling an object constructor or any of its methods, this refers to an instance of the object.
You can change the context of this using methods such as call(), apply(), and bind(). These methods call the function using the given this value and parameters.
JavaScript is an excellent programming language. A few years ago, this sentence was</p>
