JavaScript search() Method


String Object Reference Complete String Object Reference

Definition and Usage

The search() method is used to search a string for a specified value.

This method supports regular expressions. You can learn about the RegExp object in our JavaScript tutorial.

Syntax

stringObject.search(searchstring)

Parameter Description
searchstring Required. The value to search for in a string. To perform a case-insensitive search add an 'i' flag


Tips and Notes

Note: search() is case sensitive.

Note: The search() method returns the position of the specified value in the string. If no match was found it returns -1.


Example 1 - Standard Search

In the following example we will search for the word "W3Schools":

<script type="text/javascript">

var str="Visit W3Schools!";
document.write(str.search(/W3Schools/));

</script>

The output of the code above will be:

6

Try it yourself

Note: In the following example the word "w3schools" will not be found (because the search() method is case sensitive):

<script type="text/javascript">

var str="Visit W3Schools!";
document.write(str.search(/w3schools/));

</script>

The output of the code above will be:

-1


Example 2 - Case-insensitive Search

In the following example we will perform a case-insensitive search:

<script type="text/javascript">

var str="Visit W3Schools!";
document.write(str.search(/w3schools/i));

</script>

The output of the code above will be:
