问题描述
到目前为止，我正在尝试使用名为data-settings的附加属性记录对象的运动，到目前为止，我已经设法设置了某种JSON/Array，但我希望其中一个对象能够像这样保存多个哈希数组.
I'm trying to record an objects movements with an attached attribute called data-settings so far I have managed to set up some sort of JSON/Array but I want one of the objects to hold multiple arrays of hashes like so.
{ nPosX: newPX, nPosY: newPY, moves: [{ posX: newPX, posY: newPY, time: 0 }], [{ posX: newPX, posY: newPY, time: 5 }] }
但是我正在努力向moves添加另一个数组，所以我只有这个:
However I'm struggling to add another array to the moves so I only have this:
{ nPosX: newPX, nPosY: newPY, moves: [{ posX: newPX, posY: newPY, time: 0 }] }
如何将带有散列的数组推入moves?
How do I push an array with hashes to moves?
谢谢
推荐答案
el = { nPosX: newPX, nPosY: newPY, moves: [{ posX: newPX, posY: newPY, time: 0 }] }
el.moves.push({ posX: newPX, posY: newPY, time: 5 })
赠予:
{ nPosX: newPX, nPosY: newPY, moves: [{ posX: newPX, posY: newPY, time: 0 },{ posX: newPX, posY: newPY, time: 5 }] }
您的原始语法无效，因为您有两个数组，每个数组都包含一个对象，每个对象都附加到"moves"键上.这不是有效的JSON.
Your original syntax isn't valid as you have two arrays containing a single object each attached to the "moves" key. It's not valid JSON.
