【单选题】var arr = [2, 0, 6, 1, 77, 0, 52, 0, 25, 7];var newArr = [];for (var i = 0; i <; arr.length; i++) {if (arr[i] >;= 10) {newArr[newArr.length] = arr[i];}}console.log(newArr);运行上面的代码，输出结果是()。[/i][/i]
A: 2,0,6,1,0,0,25,7
B: 7,25,0,0,1,6,0,2
C: 77,52,25
D: 25,52,77
A: 2,0,6,1,0,0,25,7
B: 7,25,0,0,1,6,0,2
C: 77,52,25
D: 25,52,77
举一反三
- var arr = [2, 0, 6, 1, 77, 0, 52, 0, 25, 7];var newArr = [];for (var i = 0; i <; arr.length; i++) {if (________) {newArr[newArr.length] = arr[i];}}console.log(newArr);补充完整上面的代码，newArr数组中的数据是arr中不包含 0的数据。[/i]
- var arr = [2, 0, 6, 1, 77, 0, 52, 0, 25, 7];var newArr = [];var j = 0;for (var i = 0; i <; arr.length; i++) {if (arr[i] >;= 10) {_________________}}console.log(newArr);补充完整代码，运行后newArr数组中存放的是arr数组中所有大于等于10的值。[/i] A: j++;newArr[j] = arr[i]; B: newArr[j] = arr[i];j++; C: arr[i]=newArr[j];j++; D: j++;arr[i]=newArr[j];
- 【单选题】var arr = [2, 6, 1, 7, 4];var sum = 0;for (var i = 0; i <; arr.length; i++) {sum += arr[i];}运行上面的代码后，sum里面的值是（）。[/i] A: 20 B: 25 C: 18 D: 26
- 分析下段代码输出结果是_________。 var arr = [2,3,4,5,6]; var sum =0; for(var i=1;i < arr.length;i++) { sum +=arr[i] } console.log(sum);[/i]
- 智慧职教: var arr = [2,3,4,5,6]; var sum =0; for(var i=1;i < arr.length;i++) { sum +=arr[i] } console.log(sum);[/i]
