Array Value

Copy linkTweet thisAlerts:
Dec 15.2011

Hello,

I am currently working on building a library and having my functions(methods) within my library. I am having trouble find some code for JavaScript that can help me to do the following:

[B]Finding the total value of just the numbers in an array, even if some of the items are not numbers.[/B]

Anyone know what I am looking for?

Thanks so much!

Fred Williams

@JMRKERDec 15.2011 — If you are really interested in learning JS, you should attempt to do these simple functions yourself,

then ask for help when you can not make them work as desired.

<i>
</i>&lt;script type="text/javascript"&gt;
var arr = ['a',1,'b',2,'c',3,'d',4];

var sum = 0;
for (var i=0; i&lt;arr.length; i++) {
if (!isNaN(parseInt(arr[i]))) { sum += arr[i]; }
}
alert(sum);
&lt;/script&gt;


You will never get better without the work that goes with the knowledge.

Success!
