[javascript] How to set the max value and min value of <input> in html5 by javascript or jquery?

I am trying to find out how to set the max value and min value of html5 type input by javascript or jquery.

<input type="number" max="???" min="???" step="0.5"/>

Would someone please guide

Try this:

<input type="number" max="???" min="???" step="0.5" id="myInput"/>

$("#myInput").attr({
   "max" : 10,
   "min" : 2
});

Note:This will set max and min value only to single input

jQuery makes it easy to set any attributes for an element - just use the .attr() method:

$(document).ready(function() {
    $("input").attr({
       "max" : 10,        // substitute your own
       "min" : 2          // values (or variables) here
    });
});

The document ready handler is not required if your script block appears after the element(s) you want to manipulate.

Using a selector of "input" will set the attributes for all inputs though, so really you should have some way to identify the input in question. If you gave it an id you could say:

$("#idHere").attr(...

...or with a class:

$(".classHere").attr(...

Try this

 $(function(){
   $("input[type='number']").prop('min',1);
   $("input[type='number']").prop('max',10);
});
