This article will explain in detail how the search () method in JavaScript uses strings. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The search () method uses a string

The search method can take a string as a parameter. String parameters are converted to regular expressions:

Example

Retrieve the substring of "Runoob" in the string:

Varstr= "VisitRunoob!"

Varn=str.search ("Runoob")

The replace () method uses regular expressions

Example

Use regular expressions and are case-insensitive to replace Microsoft in a string with Runoob:

Varstr=document.getElementById ("demo") [xss_clean]

Vartxt=str.replace (/ microsoft/i, "Runoob")

The output is as follows:

VisitRunoob!

The replace () method uses a string

The replace () method takes the receive string as a parameter:

Varstr=document.getElementById ("demo") [xss_clean]

Vartxt=str.replace ("Microsoft", "Runoob")
