Insert a value from a file in an html page

[Aquatic]

Hi,
I do not know much about javascript (let alone php), so I will need a little bit more than a lead to help me with this.

What I would like is to be able to read a word (or in this case a real number) from a simple flat text file (or like the old .ini files), or even from a spreadsheet, with the following sort of data -

a1=27.99
a2=19.99
a3=53.49
c23=8.25
f217=149.99

............etc.
- where the first bit of the line is an identifier, and the second bit is the value needed. (I don't care what delimits the identifier).
Then in the html file, at the position it is needed, have an "insert the value of a3: here" type of statement.

This must have been done before, but I have spent 2 days searching for a similar idea, but to no avail.

My original idea was to have a numbers.js file containing -

var a1=27.99
var a2=19.99
var a3=53.49
var c23=8.25
var f217=149.99

.............etc.

Then in the html file have a -

<script type="text/javascript" src="numbers.js">
document.write (a1)
</script>

in the appropritate position. But it doesn't work.....:(

Can anyone help me please?

Are you looking for File Operation with JavaScript?
Sorry ...............!
It's not possible with standard JavaScript :-(

hi ...

if it would be a txt-file only you could make an attempt to load it into an iframe (may be even hidden) and then parse it with javascript and fill its values into your webpage ... but: the webpage has to be your own. this could work ... since the browser loads the txt-file like any other document and you may handle it that way ... but it would be a hack or workaround for the fact that you cannot read files with javascript except when they are loaded into the browser and you are able to retrieve its values form a document ...

kind regards

Hi,
I don't really need to do file I/O, I just want the javascript to print out the contents of a specific variable defined in numbers.js own code.
- numbers.js file just contains a bunch of variables:

var a1=27.99
var a2=19.99
var a3=53.49
var c23=8.25
var f217=149.99
.............etc.
 

Then in the html file where the variables value is needed, have a -

<script type="text/javascript" src="numbers.js">
document.write (a1)
</script>
 

Does that make sense ?

Try changing this:

<script type="text/javascript" src="numbers.js">
document.write (a1)
</script>
 

to this:

<script type="text/javascript" src="numbers.js"></script>
<script type="text/javascript">
document.write (a1);
</script>
