reverse

问题 Is there an inexpensive way to reverse: { "10": "..." "11": "...", "12": "...", "13": "...", "14": "...", } so that I get: { "14": "...", "13": "...", "12": "..." "11": "...", "10": "...", } reverse() doesn't seem to work on json objects. The only way I can think of is to loop through all the elements and create an array. feels like there should be a better way. Edit: thanks for all the help UPDATE: What about let's say if each key has chronological data. When I use $.each on the object, it

问题 In my project I have a lot of Ajax methods, with external client-side scripts (I don't want to include JavaScript into templates!) and changing URLs is kind of pain for me because I need to change URLs in my Ajax calls manually. Is there is some way to emulate the behavior of {% url %} templatetag in JavaScript? For example, print urlpatterns starting with ^ajax and later in scripts replace patterns with their actual values? That's what on my mind, and my question is - are there any common

问题 Hello I'm making RSS reader and I'm using DOM. Now I stuck, trying to reverse the order of the items in the DOMNodeList. I can make it with 2 cycles - one to make it as array and one for rsort() . Is there any way to reverse the order in the DOMNodeList or must be done with "the array way"? 回答1: There is no method for reversing a DOMNodeList.

问题 Using SCNAction.rotateByAngle(…) in my game I would press left/right/up/down keys or swipe to have an object rotate in that direction. But testing my game on El Capitan or with Metal as the renderer causes the 3D object to rotate the other way i.e. left becomes right and up becomes down. I haven't found any documentation mentioning that the rotation is "inverted" or "reversed" in El Capitan or Metal. The code is: Rotate up = SCNVector3(x:1, y:0, z:0) Rotate down = SCNVector3(x:-1, y:0, z:0)
