如何使用splice正确地将array2连接到array1
如何使用splice正确地将array2连接到array1
提问于 2018-07-25 06:31:37
在本例中，我想使用splice将array2连接或附加到array1，它返回空数组，但它应该返回两个数组中的所有值
var obj = [{"id":"36","task_name":"task1","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"37","task_name":"task2","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"38","task_name":"task3","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"39","task_name":"task4","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"40","task_name":"task5","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"41","task_name":"task6","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"42","task_name":"task7","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"43","task_name":"task8","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"44","task_name":"task9","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"45","task_name":"task10","birth_date":"2018-06-15 00:00:00","is_completed":"0"}];
var obj2 = [{"id":"46","task_name":"task11","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"47","task_name":"task12","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"48","task_name":"task13","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"49","task_name":"task14","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"50","task_name":"task15","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"51","task_name":"task16","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"52","task_name":"task17","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"53","task_name":"task18","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"54","task_name":"task19","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"55","task_name":"task20","birth_date":"2018-06-15 00:00:00","is_completed":"0"}];
var arr = Object.values(obj);
var arr2 = Object.values(obj2);
var fin = arr.splice(10,0,...arr2)
console.log(fin );回答 4

既然你已经在使用扩展运算符，为什么不对两个数组都使用它呢？另外，你不需要Object.values，因为你是从数组开始的-如果这些数组是对象的话会更合适。
var obj = [{"id":"36","task_name":"task1","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"37","task_name":"task2","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"38","task_name":"task3","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"39","task_name":"task4","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"40","task_name":"task5","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"41","task_name":"task6","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"42","task_name":"task7","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"43","task_name":"task8","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"44","task_name":"task9","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"45","task_name":"task10","birth_date":"2018-06-15 00:00:00","is_completed":"0"}];
var obj2 = [{"id":"46","task_name":"task11","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"47","task_name":"task12","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"48","task_name":"task13","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"49","task_name":"task14","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"50","task_name":"task15","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"51","task_name":"task16","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"52","task_name":"task17","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"53","task_name":"task18","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"54","task_name":"task19","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"55","task_name":"task20","birth_date":"2018-06-15 00:00:00","is_completed":"0"}];
var fin = [...obj,...obj2]
console.log(fin);

您可以在不使用splice()的情况下简单地完成此操作
var obj = [{"id":"36","task_name":"task1","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"37","task_name":"task2","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"38","task_name":"task3","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"39","task_name":"task4","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"40","task_name":"task5","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"41","task_name":"task6","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"42","task_name":"task7","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"43","task_name":"task8","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"44","task_name":"task9","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"45","task_name":"task10","birth_date":"2018-06-15 00:00:00","is_completed":"0"}];
var obj2 = [{"id":"46","task_name":"task11","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"47","task_name":"task12","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"48","task_name":"task13","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"49","task_name":"task14","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"50","task_name":"task15","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"51","task_name":"task16","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"52","task_name":"task17","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"53","task_name":"task18","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"54","task_name":"task19","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"55","task_name":"task20","birth_date":"2018-06-15 00:00:00","is_completed":"0"}];
console.log(obj.concat(obj2));

我可以确认，Array.concat()似乎给出了预期的结果：
var obj = [{"id":"36","task_name":"task1","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"37","task_name":"task2","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"38","task_name":"task3","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"39","task_name":"task4","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"40","task_name":"task5","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"41","task_name":"task6","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"42","task_name":"task7","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"43","task_name":"task8","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"44","task_name":"task9","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"45","task_name":"task10","birth_date":"2018-06-15 00:00:00","is_completed":"0"}];
var obj2 = [{"id":"46","task_name":"task11","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"47","task_name":"task12","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"48","task_name":"task13","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"49","task_name":"task14","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"50","task_name":"task15","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"51","task_name":"task16","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"52","task_name":"task17","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"53","task_name":"task18","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"54","task_name":"task19","birth_date":"2018-06-15 00:00:00","is_completed":"0"},{"id":"55","task_name":"task20","birth_date":"2018-06-15 00:00:00","is_completed":"0"}];
var fin = obj.concat(obj2)
console.log(fin);
