Javascript-Functions

Oct 10.2011

I know HTML, but I am learning Javascript for work and I am running into a few snags. Any help would be appreciated.

I have used a Javascript function for temperature conversion(attached with an external js file). When the temp is converted we are supposed to get a message box if the temps fall under a certain amount.

Example: <90 degrees celcius : a message is supposed pop up.

I haven’t been able to code the message box correctly for it to work.

@pactor21Oct 10.2011 — Assuming you had some function that returns the converted temperature, and you saved it into a variable named, celcius.

function popup(celcius)
{
// Show an alert box when celcius is less than 90.
if(celcius &lt;90)
alert('Temperture fell below 90');
}

or if you wanted to pass the temperature threshold to the function as a second parameter, you could do this

function popup(celcius, threshold)
{
// Show an alert box when celcius is less than threshold.
if(celcius &lt; threshold)
alert('Temperture fell below the threshold. Heat up!');
}

Of course, celcius and threshold should be set before passed to the function.

@KorOct 10.2011 — Not related with the programming, but the measurement unit (temperature degree) is, in all the languages: [B]Cel[COLOR="Blue"]s[/COLOR]ius[/B], after the name of the famous Swedish astronomer and physicist. ?

Success!
