JavaScript slice() method
JavaScript String Object
Definition and Usage
The slice() method extracts a part of a string and returns the extracted part in a new string. Otherwise it returns -1.
Syntax
string.slice(begin,end)
| Parameter | Description |
|---|---|
| begin | Required. The index where to begin the extraction. First character is at index 0 |
| end | Optional. Where to end the extraction. If omitted, slice() selects all characters from the begin position to the end of the string |
Browser Support
The slice() method is supported in all major browsers.
Tips and Notes
Tip: Use a negative number to select from the end of the string.
Example
Example
Extract different parts of a string:
<script type="text/javascript">
var str="Hello happy world!";
// extract all characters, start at position 0:
document.write(str.slice(0)+"<br />");
// extract all characters, start at position 6:
document.write(str.slice(6)+"<br />");
// extract from the end of the string, and to position -6:
document.write(str.slice(-6)+"<br />");
// extract only the first character:
document.write(str.slice(0,1)+"<br />");
// extract the characters from position 6 to position 11:
document.write(str.slice(6,11)+"<br />");
</script>
var str="Hello happy world!";
// extract all characters, start at position 0:
document.write(str.slice(0)+"<br />");
// extract all characters, start at position 6:
document.write(str.slice(6)+"<br />");
// extract from the end of the string, and to position -6:
document.write(str.slice(-6)+"<br />");
// extract only the first character:
document.write(str.slice(0,1)+"<br />");
// extract the characters from position 6 to position 11:
document.write(str.slice(6,11)+"<br />");
</script>
The output of the code above will be:
