Question

My intention is to create PuzzleGame , example http://migo.sixbit.org/puzzles/fifteen/(我的意图是创建PuzzleGame ，例如http://migo.sixbit.org/puzzles/fifteen/)

Main priority is to move Cells from one with value , to another one undefined .(主要优先事项是将单元格从具有值的一个移到另一个未定义的 。) Here is my function:(这是我的功能：) moveCell(row, col) { this.puzzleTable = []; let actRow = 0, actCol = 0; for (let r = -1; r <= 1; r++) { actRow = row + r; if (actRow >= 0 && actRow < this.rowCount) { moveCells(this.puzzleTable[actRow][col], row, actRow); } } for (let c = -1; c <= 1; c++) { actCol = col + c; if (actCol >= 0 && actCol < this.colCount) { moveCells(this.puzzleTable[row][actCol], col, actCol); } } } For example:(例如：) Arr[0][0] to Arr[1][1] I do not want to change their value , I want them swap(我不想更改其值 ，我希望它们交换) What is the best practice ?(最佳做法是什么？)   ask by Rejzozroutko Tezbir translate from so

Answer 1

Well you could simply store the values of both cells in two temporary variables and assign them to each other accordingly.(好吧，您可以简单地将两个单元格的值存储在两个临时变量中，并相应地相互分配它们。)

For example:(例如：) var tempA=Arr[0][0]; var tempB=Arr[1][1]; Arr[0][0]=tempB; Arr[1][1]=tempA;
