Question

I have an input box whose id is sellingprice. i want to check the input value in jquery using the if else condition and display the result value in an input box whose id is result.

example:

if the value in input box is greater 50 it will display in the other input box the word too high

i’m a newbie in jquery and confused on how to implement it. Appreciate if someone may guide me through this.

I’ll revised my question from above:

i have a table value something like this:

sellingprice      result

51                 ?
49                 ?

if the sellingprice value is greater than 50 this will be the calculation: sellingprice – 50 * 0.05 + 3.5

and if the sellingprice value is less than 50 the calculation will be: sellingprice * 0.07;

sorry i’m just trying to simplify my question but this is really the problem that i’m been facing as of this moment. Hope to guide me through this.

[edit after your update]

var sp = $('#sellingprice').val() | 0;
if (sp <= 50) {
   $('#result').val(sp * 0.07)
}
else {
   $('#result').val(sp - 50 * 0.05 + 3.5) /* check the operations order */
}

where

$('#sellingprice').val() | 0

is an explicit (and more efficient than parseInt) int casting. If you can insert also floated point values change this statement with var sp = parseFloat($('#sellingprice').val())

with a ternary operator the code is simply reduced to

var sp = $('#sellingprice').val() | 0;
$('#result').val((sp <= 50)? sp - 50 * 0.05 + 3.5  : sp * 0.07)
