以下代碼的輸出在程序之后給出。我需要按以下順序迭代 j 值 (1,2,3,4),(2,3,4,1),(3,4,1,2),(4,1,2,3) 但是它的順序是 (1,2,3,4),(2,3,4),(3,4),(4) 。任何幫助深表感謝var RRIntervalArrayDiff = [];var validRRIntervalCount =0;var RRIntervalArrayy = [0.62,0.65,0.40,2.54,0.65];var n = RRIntervalArrayy.length;for (i=0; i < n; i++){ for (j=i+1; j<n ;j++){ document.write(""); document.write("i is "+i+" j is "+j); var h = (RRIntervalArrayy[j] - RRIntervalArrayy[i]); document.write(""); if(h < 0.12){ validRRIntervalCount++; } document.write(h); if(j==(n-1)){ document.write(""); document.write(validRRIntervalCount) break; } } validRRIntervalCount = 0; document.write("");} 輸出i 是 0 j 是 1 0.030000000000000027i 是 0 j 是 2 -0.21999999999999997我是 0 j 是 3 1.92i 是 0 j 是 4 0.0300000000000000273i 是 1 j 是 2 -0.25i 是 1 j 是 3 1.8900000000000001我是 1 j 是 4 02i 是 2 j 是 3 2.14i 是 2 j 是 4 0.250i 是 3 j 是 4 -1.89000000000000011

只是按照您需要的順序打印，試試這個：

var RRIntervalArrayDiff = [];

var validRRIntervalCount =0;

var RRIntervalArrayy = [0.62,0.65,0.40,2.54,0.65];

var n = RRIntervalArrayy.length;

var revert = 0;

for (i=0; i < n; i++){

revert = 0;

for (j=i+1; j< n ;j++){

if(revert == 1 && j == i){

break;

}else if(revert == 1 && j != i){

document.write(j + 1);

continue;

}

document.write(j);

if(j==(n-1)){

if(revert == 0){

j = -1;

revert = 1;

}

validRRIntervalCount = 0;

document.write("");

}

嚴格做你想做的事：

for (i=0; i < n; i++){

var j = i + 1

var count = 0

while (count < n-1){

if (j == n)

j = 1

// do your stuff

count++

j++

}

// do your stuff

}

只需一點點模數魔法就可以為您完成工作

var RRIntervalArrayDiff = [];

var validRRIntervalCount = 0;

var RRIntervalArrayy = [0.62, 0.65, 0.40, 2.54, 0.65];

var n = RRIntervalArrayy.length;

for (i = 0; i < n; i++) {

for (j = i; j < n + i; j++) {

var newJ = j % (n) + 1;

//use newJ instead of j in your calculations

}
