javascript - calculation based on input field for a result on the fly -

this extension this thread.

---

my situation:

• i need user enter decimal value (ie 0.05) , show simple calculation on fly user types (or pastes). example shown works whole numbers not when decimal entered input field.

• i need display result in multiple places. assumed update getelementbyid getelementbyclass didn't work.

my code:

<input type="text" name="capname" id="numberfield" value="0.07" maxlength="5" /> <span name="mpd" id="mpdresult" class="mpdresult" ></span>   <span class="mpdresult" ></span> (second display)  <script> window.onload = function() {    var base = 500;    var numberfield = document.getelementbyid('numberfield');    numberfield.onkeyup = numberfield.onpaste = function() {       if(this.value.length == 0) {          document.getelementbyid('mpdresult').innerhtml = '';          return;       }       var number = parseint(this.value);       if(isnan(number)) return;       document.getelementbyid('mpdresult').innerhtml = number * base;    };    numberfield.onkeyup(); //could have been onpaste(); }; </script> 

please use var number = parsefloat(this.value);

instead of var number = parseint(this.value);
