JavaScript slice character intercept function usage

Slice usage

String.slice (NUM1, num2)
String.slice (num)

The slice () method extracts a part of the string and returns the extracted part with a new string.

return value
A new string. Includes all characters for the string stringobject from start (including start) to end ending (excluding ends).

Instance

<script language= "JavaScript" >
<!--
var myString = new String ("This is a Test");

var myslice = Mystring.slice (0,6);

document.write (' The ' the ' the ' the ' 7 characters our string, ' + myString ');
document.write (', are: ' + myslice);
Document.close ();

-->
</script>

Note: You can use negative values to select elements from the tail of the array.

Note: If end is not specified, then the slice () method selects all elements from start to ending of the array.

Instance

<script type= "text/web Effects" >

var arr = new Array (3)
Arr[0] = "George"
ARR[1] = "John"
ARR[2] = "Thomas"

document.write (arr + "<br/>")
document.write (Arr.slice (1) + "<br/>")
document.write (arr)

</script>

Output

George,john,thomas
John,thomas
George,john,thomas

In this example, we will create a new array and then display the elements selected from it:

<script type= "Text/javascript" >

var arr = new Array (6)
Arr[0] = "George"
ARR[1] = "John"
ARR[2] = "Thomas"
ARR[3] = "James"
ARR[4] = "Adrew"
ARR[5] = "Martin"

document.write (arr + "<br/>")
document.write (Arr.slice (2,4) + "<br/>")
document.write (arr)

</script>
