Javascript function argument

Question

I am using a javascript function and I am trying to pass a string of characters that come from form fields. I am trying to achieve this:

function_name(55,document,form.field1.value,form.field2.value)

but I am trying to pass the above as one argument, for example '44,55,66'

I tried the following without success:

'this.value+','.charAt(0)+document.class.Q_11_2c.value+','.charAt(0)+document.class.Q_12_3c.value'

The function sample should be: function_name(55,document.form.field1.value, document.form.field2.value) — Evan

If you want your function to accept a single argument, rewrite its definition accordingly and remove any charAt() from its argument in call.

Thanks for taking the time to respond. But may I ask how can I pass as an argument a comma (,)?

@Evan "Serialize" to a string (Array.join) and "de-serialize" (String.split) later. However, this is a broken design -- it's hard to get correct (what if a comma comes in the data?) and just useless at this level. Perhaps update the post to include the end result for suggestions on how to correctly write the code.

your function:

function_name(dataString) {
//parse the param string to get values you need 
//dataString.split("unique-delimiter")
}

now call it as:

//make values a single string and pass it to the function
//mydataString = dataArr.join("unique-delimiter") ; 
function_name(mydataString);

just noticed @pst's answer, yes in the calling part you can use Array.join and in the function you can use String.split.
