case statements

[florida]

I have alot of these "if" statements ( I listed 2 as an example) and would like to put them in a case statement. My ifs work great for checking blank spaces in my form but now I would like to make it all into case statements.


function stdRequire()
{

stdInfo = ''
ct = 0


if(/^\s*$/.test(document.stand.poc_fnm.value))
{
stdInfo += "\npoc first name";
ct++;
}

if(/^\s*$/.test(document.stand.poc_lnm.value))
{
stdInfo += "\npoc last name";
ct++;
}

etc...

if (stdInfo != '')
{

alert(stdInfo);
return false;
}


}



/////
//My attempt using CASE statements:
/////

function stdRequire()
{

stdInfo = ''
ct = 0

switch(n)
{
case(/^\s*$/.test(document.stand.poc_fnm.value):

stdInfo += "\nPOC's First Name";
ct++;
break;

case(/^\s*$/.test(document.stand.poc_lnm.value):

stdInfo += "\nPOC's Last Name";
ct++;
break;

etc...

Any advice on if this is correct??

It looks to me like you haven't defined "n" yet that you're using in your switch statement. It looks like what you're trying to do is:

switch(/^\s*$/.test(document.stand.poc_fnm.value)){

case 'true':
//do stuff
break;

case 'false':
//do stuff
break;
}



The Regular Expression test method will return a boolean value. Your two cases should therefore be the possible values of that boolean value.
I'm not sure that you really need a case/switch statement for a two case scenario. Why are you changing what you already have?

I don't think you can do what you are asking

switch (expression) {
case label : statements; break;
case label : statements; break;
... default : statements;
}

The expression must evaluate to match the 'label'
Javascript case/switch is not your typical case statement.

Hope that helps (or hinders) a little.
