[Javascript] RE: Checking for date

Tue Jul 30 12:23:45 CDT 2002

Andrew, 
	this is a fairly comprehensive script for checking dates. It trims
entries of whitespace, then checks the format for dd/mm/yyyy, checks to see
if day and months values are valid - ie it calculates leap year values for
Feb etc.
The instruction: <%=FormatDate("PL", Now())%> gets an ASP date and the
confirm() gives the user the options to revert to today's date - you may
have to change or remove this depending on what server environment you use.

The function works in IE,NS4,NS6.

To put it in a page use something like <input type="text"
onblur="val(this)">.

function getLeap(hmm){
	if((hmm%4==0)&&(hmm%100!=0||hmm%400==0)){
	return 29
	}
	else{
	return 28
	}
}

function val(elem){
txt = elem.value
txt = txt.replace(/^\s+/,"");
txt = txt.replace(/\s+$/,"");
elem.value = txt;
var rege = /\d\d\/\d\d\/\d\d\d\d/;

var brief = txt.match(rege)

	if(!brief){//if date is not of format dd/mm/yyyyy
	if(confirm('This is not a valid date, do you wish to\n revert to
today\'s date?'))
	{elem.value="<%=FormatDate("PL", Now())%>"}
	else
	{elem.value="";}
	return;}

var info = brief[0].match(/\d+/g)

var dateInfo = new Array()
dateInfo[1] = 31;
dateInfo[2] = getLeap(info[2]);
dateInfo[3] = 31;
dateInfo[4] = 30;
dateInfo[5] = 31;
dateInfo[6] = 30;
dateInfo[7] = 31;
dateInfo[8] = 31;
dateInfo[9] = 30;
dateInfo[10] = 31;
dateInfo[11] = 30;
dateInfo[12] = 31;

	if(info[1]>12){//if month is greater than 12
	if(confirm('This is not a valid month, do you wish to\n revert to
the default date?'))
	{elem.value="<%=FormatDate("PL", Now())%>"}
	else{elem.value="";}

	return;}

	if(info[0]>dateInfo[parseInt(info[1])]){//if day is not valid -
leapyears/feb taken into account
	alert('This is not a valid day');
	elem.value="";
	return;}
}

Reply-To: javascript at LaTech.edu

What I want to do is move the div element which has the
image of a red ball in it.  I am trying to do so by
changing the style's margin-left value to 100 points.
I am using IE5.5.  Simply stated, I do not know how to
write the function moveBall.  Will someone please write
in the correct process for this funciton and give a few
comments to explain what they did.

	document.all.red.style.marginLeft="100pt";

	For what it's worth, "red" may be a bad name to give an element; I
know
it's recognized color in CSS and HTML.  I try to stay away from words that
mean anything when naming my objects... just my two cents, so use it as you
will.

Cheers,

Peter

Reply-To: javascript at LaTech.edu

Hi All,

I have a site I'm putting together which is framed. It pops up a small 
navigation page with links to other pages. I'd like the links in this 
navigation page to open the selected page in the parent framed site.

There are 4 frames on the main page: topleft, navleft, navtop and 
mainFrame. The links in the popup nav window need to load the linked 
pages in mainFrame.

How can I do this?

Phill,

	First, make sure that when you open the window, you set it to a
variable,
and then assign the opener property in case it wasn't set, e.g.

var newWin = window.open(yadda yadda);
newWin.opener = top;

	And then in the new window:

window.opener.frames.mainFrame.location.href = "whatever.html";

Regards,

Peter

If a user types in a date on a form, like so

30,June 2002

How could I check in Javascript to ensure it is a valid date, and in the
format I want, say,    dd mmm,yyyy

Check out http://javascript.internet.com/forms/ for some general date
validation scripts. You may be able to tailor them to your specific needs.

	Maybe it's just old-school precaution, but not every browser assigns
the
opener attribute implicitly.  I didn't know the target audience, and an
extra line or two of code won't make or break a site.

I somewhat agree with Peter. Although I would not use "red" because it may 
be a recognized attribute, it's usually good programming practice to give 
your objects some form of recognizable name. Maybe something like 
'id="idMobileBox"'.

Thank you Peter,
I like to be 'old school'  too but sometimes one misses things like this.
