JavaScript - 比较两个多维数组

Question

我有两个多维数组:

首先是类似的东西 (['one','one','three'],['four','five',five'],['one','one','one'])

而第二个是这样的 (['one','one','nine'],['one','one','one'],['two','two'],['two','two','two']...)

现在,我想要的是找到第一个数组与第二个数组的匹配第一个索引,但两个数组中至少前两个索引的位置也必须匹配,例如:

first_array(['one','one','three'],['four','five',five'],['one','one','one'])

会匹配

second_array(['one','one','nine'],['one','one','one'],['two','two'] ['two','two','two "] ...)

输出将是例如.'警报(' 匹配".).

我试过了

for(i=0; i<1; i++){
    if(first_array[0] == second_array) console.log('Match');
    else console.log('No match');
}

但我总是得到'不匹配',尽管有一场比赛.PS在'for'循环中,我的i是i <1,因为我只想比较first_array的第一个索引和完整的second_array.

提前致谢

Answer 1

var md1 = [['one','one','three'],['four','five','five'],['one','one','one']];

var md2 = [['one','one','nine'],['one','one','one'],['two','two'],['two','two','two']];

//Iterate through all elements in first array
for(var x = 0; x < md1.length; x++){

    //Iterate through all elements in second array    
    for(var y = 0; y < md2.length; y++){

      /*This causes us to compare all elements 
         in first array to each element in second array
        Since md1[x] stays fixed while md2[y] iterates through second array.
         We compare the first two indexes of each array in conditional
      */
      if(md1[x][0] == md2[y][0] && md1[x][1] == md2[y][1]){
        alert("match found");
        alert("Array 1 element with index " + x + " matches Array 2 element with index " + y);
      }
    }
}
