What if you do this during battle and the enemy destroys the rope after seeing you climb up it??

 The end of the rope at the top would probably just hang there. And if they destroyed the whole rope I don’t think that would end the Spell early. There just wouldn’t be a rope there anymore and there would be no indication of the spell.

My question is if you can hide in the space during combat and just like stick your arm out to cast a fireball or something and then pull it back in?

Can you cast it inside of itself, to allow for more characters to be stored?  Or will it cause the universe to turn inside out?  What would be interesting is if you don't keep track of time, and the 1st pocket dimension closes before your 2nd pocket dimension.  What happens then?  I would assume the 1st spits out the 2nd into the current plane, then the 2nd one would spit everyone out where they started.

How does this spell work when it comes in contact with a bag of holding?

 

Exactly what you are implying. The Bag of Holding says this:

Placing a bag of holding inside an extradimensional space created by a handy haversack, portable hole or similar item instantly destroys both items and opens a gate to the Astral Plane. The gate originates where the one item was placed inside the other. Any creature within 10 feet of the gate is sucked through it to a random location on the Astral Plane. The gate then closes. The gate is one-way only and can't be reopened.

 

If you unwittingly climb into the extradimensional space created by Rope Trick with your trusty bag of holding at your side, you turn your possible short rest into a REALLY long one, after the rest of the party beats you to death for your stupidity.

Unfortunately, that's the kind of thing that nobody usually thinks about, something that the DM might overlook it, or the player might until it's too late. Although I never played 3.5 (please don't kill me), I believe it actually used to have a warning label on this spell: "Note: It is hazardous to create an extradimensional space within an existing extradimensional space or to take an extradimensional space into an existing one." The 5e description above explicitly says "extradimensional space" four times, as if they were saying, "Let's see if they figure this one out."

 RAW you are save because it is not an "item". RAI you are save because obviously no authour ever wanted to enfore every kind of holding item to be strictly limited to remain on the plane it was created at.

Could the caster (or an ally) grab hold of the rope as it's rising up, to avoid pesky Athletics checks for climbing up a rope?

Do this with a bag of holding instant escape of to get ride of ur enemies 

Bag of holding 😈

Quote from Quirks >>

Arcane Tricksters or Eldritch Knights could also take it.

Since it does not say a minimum length of rope or quality of rope it has a few options for interesting uses. A short rope would make for a quick accent. A poor quality rope could be made from things like bed sheets while in prison, at least a nice prison.

1. Could be use for a B&E where you find a out of the way place less than an hour before closing, cast the spell, climb the rope, and then wait for closing and then descend.

2. Could be used to hide something for an hour.

3. Used to lay an ambush, although you can't attack from it, you can still drop out and attack. Dropping a rock from just outside and climbing back in could be useful.

4. Create a distraction when the contents of iron pots and other noisy things drop out after an hour. Or a time delayed firebomb when alchemist fire was loaded into the space.

5. Make it look like you escaped an enclosed space if you happen to have access to parchment and corn extract while imprisoned.

6. Have a space place to take a short rest.

7. Depending on the DM, could be used to make a bag of holding bomb as it is putting an interdimensional space inside another.

The limits are the imagination of the caster and the conditions they find themselves in.

 3. Used to lay an ambush, although you can't attack from it, you can still drop out and attack. Dropping a rock from just outside and climbing back in could be useful. you would have to be carfeul about held attacks

or just hang from rope and attack

not if you interupt for abit to get down

Quote from norishiuido >>

You'd have to be kind of crazy to use this as a short rest. The duration is 1 hour, so you need to get into it straight away otherwise enemies will ambush you and stop your short rest when it pops.

There's also nothing stopping enemies from following you up there.

 pull the rope up after you

 wait for one hour or disple magic

Dont forget to use your familiar's movement so it can bring the rope up so no one else can climb it.

so if a player is being hanged, they could cast this. sence the rope is already perpendicular

then just climb up, pull the rope inside. and untie it?

Fill it with 100 flasks of alchemists fire, and walk away.

Time. Bomb.

 It would still be tied to whatever it was tied to originally.   But you could climb into the space created & be safe from being attack while you get the rope off your neck.  Until someone climbs in after you...

Though I could see a GM stating that the spell doesn't progress "until the whole rope hangs perpendicular to the ground." because both ends are tied into knots / around something.  Also, could be tough to climb the rope if your hands are tied behind your back.

So you are telling me the material component is a paper bag filled with popcorn crumbs. So that's why my friend's arcane trickster always mentions dropping the popcorn bag she was eating from while watching us die before hiding in her magical 5 feet rope and has her owl familiar take it to a safe place.

Would a caster be able to cast spiritual weapon or arcane hand, step into this extradimensional space, look out and continue to provide vision to control the spiritual weapon to continue attacking with it?

Actually, this wouldn't because of a very specific word in the bag of holding wording: item.

Placing a bag of holding inside an extradimensional space created by a handy haversack, portable hole, or similar item

The extradimensional space from rope trick isn't created by an item (the rope); it's created by a spell. So . . . you're fine to rope trick it with a bag of holding. A Djinni vessel, though . . . ehh, maybe??
