I am using a text box which would allow only two digits(i.e.,1-99). It should restrict all other keys except 1-99 while entering into the textbox

I am using a text box. It should restrict all other keys except 1-99 while entering into the textbox. i need code to restrict them.

On SO it's appreciated when you make an effort at solving your issue. What have you tried? Please show the current code you're using and what specifically it isn't doing. — DACrosby, Aug 26 '15 at 04:35

<input type="number" onkeydown="limit(this);" onkeyup="limit(this);">

LIMIT With JS

function limit(element)
{
var max_chars = 2;

   if(element.value.length > max_chars) {
       element.value = element.value.substr(0, max_chars);
   } 
}

i want to restrict the other keys like 123, 786,etc. the third digit should also be restricted. – harika mandula Aug 25 '15 at 10:36
yes, with this way you can validate with regular expression var regular /^[0-9]{1,99}$/ – Ghulam Ali Aug 25 '15 at 11:11

The answers provided for this SO question should help you figure it out. It's a combination of HTML and JavaScript. There are two main ideas: 1 - use input with type=number as Ghulam Ali suggested to restrict inputs to your range of values and augment that with some JS to restrict the length. 2 - use input with type=text to restrict the length and augment it with some JS to restrict inputs to your range of values.
