javascript jquery tofixed不起作用

Why does this not work? Can anyone explain this to me?

t = setInterval(refresh_div,100);
    function refresh_div2() {
    jQuery.ajax({
        url:'livesatoshi.php',
        type:'POST',
        success:function(results2) {
            jQuery(".satoshi").html(results2).tofixed(2);
        }
    });
}

The function name is not correct and the toFixed function needs to be corrected , as below :-

t = setInterval(refresh_div2(),100);

success:function(results2){
    jQuery(".satoshi").html(results2.toFixed(2));
}

Put the above code in proper place and you will get your desired result .

toFixed() is case sensitive and is only a prototype function for Number data types. results2 is likely not a Number type at this point, so you'll need to convert it to one with Number.parseFloat().

Assuming you want the value of results2 as a number with 2 decimal points, you'll want to use:

Number.parseFloat(results2).toFixed(2); // returns "###.##" as a string
