need a special kind of time object

[lemorris]

Ok here's the challenge.

I need for people to type -30 into a field, then when they press TAB, have the field display a time that is 30 minutes prior to the current time.

Is this possible?

I tried to make it work with 2 text fields using this:


on(keyPress "<Tab>"){
if (tk != -30){
feedback.text = "wrong";
}else{
mydate = new Date();
code = mydate.getHours() + ":" + (mydate.getMinutes(-tk))
if (mydate.getMinutes() > 59){
code = mydate.getHours() - 1 + ":" + (mydate.getMinutes()-tk)
}
}
}

I failed badly. I'm frustrated because my code won't work, and that caused me to think I'm fat and ugly.

Please help me get this time thing working so my self-esteem can be restored.

Thanks,

This isn't the whole thing, but gives you the 'time manipulation' stuff. Dat2 will be a date object with the desired time.

Date.getTime() is very useful because it represents the date as a single number (milliseconds since 1970). Then you can subract (or add) whatever you need, and then convert this back to a date object.

For your date, I'm subtracting 30 minutes, expressed in milliseconds.

code:

---

dat = new Date();



dat2 = new Date(dat.getTime() - 30*60*1000);



trace("current time is : " + dat);

trace("previous time is : " + dat2);

Thanks Jbum, but I'm still floundering over here.

I just need the hours and the minutes.

Here's what I have:

On frame one:


stop()
mydate = new Date();
hrs = mydate.getHours()
mins = mydate.getMinutes()
if (mins < 10){
mins = "0"+mins
}
current = hrs + ":" + mins


On the stage I have an input text box named : tke

I have a dynamic text box var name : current

Another dynamic text box var name : feedback

I have a button that will be invisible with this code:


on(keyPress "<Tab>"){
right = "-30"
if (tke.text = right){
if (mins < 30){
mydate = new Date();
mins2 = (mydate.getMinutes()+30)
hrs2 = (mydate.getHours()-1)
current = hrs2 + ":" + mins2
}
if(mins > 30){
mydate = new Date();
mins3 = (mydate.getMinutes()-30)
hrs3 = mydate.getHours()
current = hrs3 + ":" + mins3
}

if(tke.text != right){
feedback.text = "wrong";
}
}
}


I need the user to type -30 into the tke input field and when they push tab the current time displayed is 30 minutes ago. I need to account for the hour if it's like 3:07 or something too.

If they type anything else in the input text field I want an error message to pop up that say's wrong. But no other changes.

I realize I may be over doing this, but I can't see another way.

I was close with your method but I panicked again.

Thanks for your help.

Here's a modification of my above script. It extracts the hours and minutes from dat2, and then adds leading zeros.

code:

---

dat = new Date();

dat2 = new Date(dat.getTime() - 30*60*1000);

hrs = dat2.getHours(); // extract hours

mins = dat2.getMinutes(); // extract minutes

hrs = String(hrs+100).substr(1,2); // add leading zeros

mins = String(mins+100).substr(1,2); // add leading zeros

prevtime = hrs + ':' + mins;

trace("current time is : " + dat);

trace("previous time (HH:MM) is : " + prevtime);

Thanks Jbum!!

Not only did I get the code to do what I needed. A hot chick winked at me while I was driving my '58 http://www.58vw.com. I owe you many thanks. My self esteem is restored.

Here's how I used your code:

onClipEvent(enterFrame){

dat = new Date();
dat1 = new Date(dat.getTime() - 30*60*1000);
dat2 = new Date(dat.getTime() - 30*60*1000);
hrs = dat2.getHours(); // extract hours
hrs1 = dat.getHours(); // extract hours
mins = dat2.getMinutes(); // extract minutes
curmins = dat.getMinutes(); // extract minutes
hrs = String(hrs+100).substr(1,2); // add leading zeros
hrs1 = String(hrs1+100).substr(1,2); // add leading zeros
mins = String(mins+100).substr(1,2); // add leading zeros
curmins = String(curmins+100).substr(1,2); // add leading zeros
prevtime = hrs + ':' + mins;
curtime = hrs1 + ':' + curmins;
//trace("current time is : " + dat);
//trace("previous time (HH:MM) is : " + prevtime);
}

I doubled up so I could display both in text fields on the stage.

Thanks again.
