JavaScript how to solve NaN when i deleting number?

This is the code when i am adding in all textbox it works fine but after removing number it shows NaN

``````function sumVal()
{
var total = 0;
var coll = document.getElementsByTagName("input")
for ( var i = 0; i<coll.length; i++)
{
var ele = coll[i];
total += parseInt(ele.value);
}
var Display = document.getElementById("Display");
Display.innerHTML = total;
}

<input onkeyup="sumVal()" />
<input onkeyup="sumVal()" />
<input onkeyup="sumVal()" />
``````

Try checking that your value is NaN before adding it to the total:

``````total += (isNaN(parseInt(ele.value, 10)) ? 0 : parseInt(ele.value, 10));
``````

Also, don't forget the radix for `parseInt` (or use `parseFloat` in the event you have decimal places):

An integer that represents the radix of the above mentioned string. Always specify this parameter to eliminate reader confusion and to guarantee predictable behavior. Different implementations produce different results when a radix is not specified.

``````var nums = [10, "sads", 44, 16];
var numsLen = nums.length;
var total = 0;

while(numsLen--){
total += (isNaN(parseInt(nums[numsLen], 10)) ? 0 : parseInt(nums[numsLen], 10));
}
``````

In this example, since "sads" is not a number (NaN) we add 0 to the total.

You should make sure that the element's value is a valid number first:

``````if (isNumber(ele.value))
total += parseInt(ele.value, 10);
}
``````

You'll need this function:

``````function isNumber(n) {
return !isNaN(parseFloat(n)) && isFinite(n);
}
``````

The above function is the famous `isNumber` function from here.
