Question

怎么用JS对二维数组进行组合排序

Answer 1

function doExchange(doubleArrays){
var len=doubleArrays.length;
if(len>=2){
var len1=doubleArrays[0].length;
var len2=doubleArrays[1].length;
var newlen=len1*len2;
var temp=new Array(newlen);
var index=0;
for(var i=0;i<len1;i++){
for(var j=0;j<len2;j++){
temp[index]=doubleArrays[0][i]+
doubleArrays[1][j];
index++;
}
}
var newArray=new Array(len-1);
for(var i=2;i<len;i++){
newArray[i-1]= doubleArrays[i];
}
newArray[0]=temp;
return doExchange(newArray);
}
else{
return doubleArrays[0];
}
}
