Get element value and add them (parseFloat seems to fail)

I have the code above:

var element1=$("#element1").val(); 
//the element1 value is 12.60 
//html code for this element <input id="element1" value="12.60" />
element1=parseFloat开发者_JS百科(element1).toFixed(2);

var element2=$("#element2").text(); 
//the element2 value is 1.00 
//html code for this element <span id="element2">1.00</span>
element2=parseFloat(element2).toFixed(2);

var addthem=element1+element2;

console.log(addthem);

And of course I am expecting to see 13.60 but I get 12.601.00 (add the as string).

Am I missing something?

parseFloat is working fine, but then you're explicitly getting a string version of the values (via toFixed), and so + concatenates the strings. Only use toFixed at the point you want to convert the numbers to a string (for instance, to output to an element).

---

A quick check with Firebug, shows that the toFixed() method returns a string in Firefox:

var f = 16.055;
console.log(typeof(f.toFixed(1)));

returns: string

Thus you should change the second last line to:

var addthem = parseFloat(element1) + parseFloat(element2);

toFixed(), i believe, returns a String as its datatype. The + operator you use in var addthem=element1+element2; works as string concatenation, since + is overloaded in JavaScript. If any of the operands is a string, a string value is returned.
