javascript - 如何从二维数组中删除特定的一维数组？

Question

我的项目功能如下:我有一个二维数组，那么应该删除特定的一维数组。二维数组为:

//ID,姓名,年龄,分数。学生的ID是唯一的。

var arr1=[["1","aaa","20","90"],
      ["2","bbb","21","80"],
      ["3","ccc","22","70"], 
      ["4","ddd","23","60"],
     ];

var arr2=["3","ccc","22","70"];

我想得到一个二维数组，结果如下:

result=arr1=[["1","aaa","20","90"],
      ["2","bbb","21","80"],
      ["4","ddd","23","60"],
     ];

我写了一些代码，但出现逻辑错误。jsfiddle的URL是:Edit fiddle

非常感谢。

Answer 1

那么您想删除arr1中的数组，其ID与arr2中的ID相对应吗？如果这就是问题所在，只需写:

for(var i=0;i<arr1.length;i++){
    if(arr1[i][0] === arr2[0])
        arr1.splice(i, 1);
}
