Can the Javascript validate the input whether is numeric o not???
And how is the coding???

Thank you.

JavaScript provides two functions to do this task. refer the code below

function test(x)
{
    var z=x;
    // This function will tell you the data type of the passed value, numeric, string

    alert(typeof(z))

    // This function will tell return true if numeric is not passed or false

    alert(isNaN(z))

}

test(145)
