parseInt() Function, JavaScript

You can use the parseInt(), Function from JavaScript to  parse a string / variable or other value and get in return an integer.
In the example below, you will see a practical application of this built in Function.

Syntax:
parseInt("String" or VariableName)

See the example below.









<script type='text/javascript'>
var b='34.54354'
var t='11 at this table.'

document.write('This example uses parseInt() Function and returns' + '<hr>' +parseInt(b) +'<hr>')

document.write('This example does not and returns' + '<hr>' + b +'<hr>')
document.write('This example uses parseInt() Function and returns' + '<hr>' +parseInt(t) +'<hr>')
document.write('This example uses parseInt() Function and returns' + '<hr>' +t)

</script>
