Hi Cluskitt,<br />
<br />
I notice that If I insert a value 500 it pass and it doesn't. <br />
<br />
only value = my suggested value or multiply by itself<br />

Hi Cluskitt,

I notice that If I insert a value 500 it pass and it doesn't.

only value = my suggested value or multiply by itself



<div>
I thought you meant only increments of the value or increments of half the value.<br />
Just change the if to:<br />
if (FieldValue % MyValue == 0 || FieldValue == MyValue / 2)
</div>

<div class="content wysiwyg-content">
Hello, <br />
<br />
I have a input and I suggest a value, for example:<br />
<br />
200<br />
<br />
this field only must accept a multiply value from itself or divided by itself. <br />
<br />
Then<br />
<br />
It only can accept: 200 - 400 - 600 - 800 - 900 etc<br />
<br />
thanks<br />
Alex

How can I accept only a value valid in my input?

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.
