When trying to sort based on values that do not fit the standard ascending and descending sort logic provide by your database engine you can use the following decode() function to sort based on custom value ordering. By ordering your value list in a…

Sorting in Javascript with sort uses lexical sorting by default, which means it will sort in alphabetical order. That's fine for strings of characters, but it means that arrays of numbers don't sort in numerical order! To fix that, we'll pass a custo…

1,layer是对游戏中所有物体的分类别划分,如UIlayer, waterlayer, 3DModelLayer, smallAssetsLayer, effectLayer等.将不同类的物体划分到不同的层,便于相机拣选,在相机的cullmask中可以选择渲染哪些层,不选择的层则不会渲染.还可以用于射线检测对象的拣选,可以指定只对某些层的对象进行射线检测. 2,canvas默认是屏幕空间的2D对象,在屏幕空间时仅具有sort order属性,当把它设置为世界空间时,sort order属性消失…

如果在ECshop后台批量添加过大量类目的人都能体会到是多么的不方便(这点还是要说一下ECshop的产品经理,细节上还是要多注意),每次添加都需要在几百个类目里面找到要添加的父类目也是一个麻烦事,比如我的 Tao Fashion 站,里面一共有400多个类目 每次添加一个新类目,即使是同一父类目下的,都需要从头再找一遍,非常不方便,设置类目的顺序的时候,也要自己记着这个父类目下已经添加几个了,记着下一个添加的时候+1,经常弄错. 咱是新人类,要用技术的办法解决这个问题,实现在Category L…

Question 791. Custom Sort String Solution 题目大意:给你字符的顺序,让你排序另一个字符串. 思路: 输入参数如下: S = "cba" T = "abcd" 先构造一个map,sMap key存储S中出现的字符,value存储字符在S中的位置 c -> 0 b -> 1 a -> 2 再构造一个int数组,sIdx sIdx,存储S中的字符在T字符串中出现的次数 遍历T字符串 如果字符在sMap中,sIdx…

S and T are strings composed of lowercase letters. In S, no letter occurs more than once. S was sorted in some custom order previously. We want to permute the characters of T so that they match the order that S was sorted. More specifically, if x occ…
