Hi everyone,

I've just developed little code which calculates a certain score
depending on there values. The javascript works in the form. However
when i tried putting on to an external javascript document
("parScore.js"). It doesn't calculate the way it suppose to. Its like
it needs the reference from the form fields :s

I've referenced it as this in the html....

<script src="javascript/parScore.js"></script>


My javascript file contains this code....

<!--

The code does work in the html file. But to an external .js file it
does put something in the parscore field and msgbox does appear. But i
get the value 0 all the time. Regardless of me filling in the fields
in the html form.

Have i missed something out?

Do you really have comment markers at the beginning and end of the js
file? If so, remove them. You don't need them when it's in the HTML,
either. That was used for supporting obsolete browsers.

If that still doesn't work, try installing Firebug (you should anyway)
and debugging the code in Firefox.

In your html file this code as given can only works if it is in end of
the file

after the navigator have seen the elements referenced in the script :

// variables to hold the values of basic obs
var vHR = document.getElementById('HR').value;
var vTemp = document.getElementById('Temp').value;
var vRespRate = document.getElementById('RespRate').value;
var vBP = document.getElementById('BP').value;
var vSa02 = document.getElementById('Sa02').value;
var vGCS = document.getElementById('GCS').value;
var vUrineOutput = document.getElementById('UrineOutput').value;
var vLevelOfCons = document.getElementById('LevelOfCons').value;
var vO2Stat = document.getElementById('O2Stat').value;

put your global variables values somewhere the navigator can understand
of what you talk (after loading ?)


// begin script :

// variables to hold the values of basic obs
var vHR, vTemp, vRespRate, vBP, vSa02,
vGCS, vUrineOutput, vLevelOfCons, vO2Stat;

window.onload = function() {
vHR = document.getElementById('HR').value;
vTemp = document.getElementById('Temp').value;
vRespRate = document.getElementById('RespRate').value;
vBP = document.getElementById('BP').value;
vSa02 = document.getElementById('Sa02').value;
vGCS = document.getElementById('GCS').value;
vUrineOutput = document.getElementById('UrineOutput').value;
vLevelOfCons = document.getElementById('LevelOfCons').value;
vO2Stat = document.getElementById('O2Stat').value;
}

//variables to hold the score
var vScoreHR,
vScoreTemp,
vScoreRespRate,
vScoreBP,
vScoreSa02,
vScoreGCS,
vScoreUrineOutput,
vScoreLevelOfCons,
vScoreO2Stat;

that can't work except if each of them is a number
