In jQuery, what's the best way of formatting a number to 2 decimal places?

Question

This is what I have right now:

$(\"#number\").val(parseFloat($(\"#number\").val()).toFixed(2));

It looks messy to me. I don\'t think I\'m

We modify a Meouw function to be used with keyup, because when you are using an input it can be more helpful.

Check this:

Hey there!, @heridev and I created a small function in jQuery.

You can try next:

HTML

​

jQuery

// apply the two-digits behaviour to elements with 'two-digits' as their class
$( function() {
    $('.two-digits').keyup(function(){
        if($(this).val().indexOf('.')!=-1){         
            if($(this).val().split(".")[1].length > 2){                
                if( isNaN( parseFloat( this.value ) ) ) return;
                this.value = parseFloat(this.value).toFixed(2);
            }  
         }            
         return this; //for chaining
    });
});
