Java Script Help

In document ready you'd do something like:

$('#m1-sum-arg3Field').text("1.50")

whatever fields are appropriate.

where abouts in the code would i put that, i just put it here and nothing happened

(i didnt bother copying all the code)

/**
* Called when document is loaded.
*/
phoneui.documentReadyHandler = function() {
}
$('#m1-sum-arg3Field').text("1.50")
}

function updateTotal() {
//read arg1-arg4 input values
// inspect the html file to get the field IDs
var arg1 = parseFloat($('#m1-sum-arg1Field').val());
var arg2 = parseFloat($('#m1-sum-arg2Field').val());
var arg3 = parseFloat($('#m1-sum-arg3Field').val());
var arg4 = parseFloat($('#m1-sum-arg4Field').val());

//convert all non-numeric (NaN) inputs to 0
arg1 = isNaN(arg1) ? 0 : arg1;
arg2 = isNaN(arg2) ? 0 : arg2;
arg3 = isNaN(arg3) ? 0 : arg3;
arg4 = isNaN(arg4) ? 0 : arg4;
//compute sum of args
sum = (arg1*arg2)+((arg1*arg1)/(2*(arg3+(0.1*arg4))));

can you not write iPhone apps in java? Java is a much nicer language to learn/understand than JavaScript... Or even Objective C?

 

[Andy_con]

mobione uses java script to do the iphone app

 

[Andy_con]

things are looking good just one more bit of java script to get sorted and the app is done

ok so my next big thing to do

this is the first page -

i can probably faff around with the coding i have to make this page. but i need this page to turn mph/kph into metres per second and put that result automatically into the speed column on the second page. how do you get the result to post in a completely seperate file??

second page -

Do it all on one page, seperated into div's (hide the ones that aren't currently on show).

In just pure html, it will be a lot easier & quicker within one page.

Ahhh i don't want to start all over again.

you make it sound so simple...

i do have a copy of dreamwaeaver and a rough idea how to use it
