[英]Is it possible to store a javascript function call and execute it when some variable is set?
[英]Is it possible to store a function call in a dynamic variable?
還有一個動態變量名。 我試過這樣做:
let positionAx = [450, 420, 425, 425, 430, 444, 449, 453, 449, 471, 475]; // x + z Coordinates for the following units in order:
let positionAz = [541, 532, 532, 558, 558, 566, 566, 566, 562, 542, 546]; // CC, melee x2, ranged x2, female x4, cavalry x1, special x1
let dynamicShiftx = ["position" + poppedPosition + "x" + ".shift();"];
let dynamicShiftz = ["position" + poppedPosition + "z" + ".shift();"];
let shiftPositionX = dynamicShiftx;
let shiftPositionZ = dynamicShiftz;
dynamicShiftx
和dynamicShiftz
產生我需要的東西,即positionAx.shift();
和positionAz.shift();
但它實際上並沒有改變那個價值。 我究竟做錯了什么? JS新手順便說一句。
使用 object 對 arrays 進行分組,然后您可以生成一個字符串鍵,讓您可以使用括號表示法訪問所需的數組,如下所示:
let positions = {
Ax: [450, 420, 425, 425, 430, 444, 449, 453, 449, 471, 475],
Az: [541, 532, 532, 558, 558, 566, 566, 566, 562, 542, 546],
Bx: ...
...
};
let shiftPositionX = positions[poppedPosition + "x"].shift();
let shiftPositionZ = positions[poppedPosition + "z"].shift();
