从JavaScript中的数组中删除特定对象

Question

I have a object of array stored in local-storage as shown below

  var todos = [
    {"id":0,"text":"Make lunch","completed":true},
    {"id":1,"text":"Do laundry","completed":false},
    {"id":2,"text":"Complete Project","completed":true}
  ]

How can i delete all objects that are completed? Please tell me how to delete it with splice method as i cant replace array i want to just remove it from array!(as my project requirements) Thanks for any help

Answer 1

您可以尝试使用javascript array.filter

todos=todos.filter(todo=>!todo.completed);

Answer 2

这样的事情会做的

var filteredAry = todos.filter(function(e) { return e.competed !== 'true' })

Answer 3

You can filter uncompleted todos like:

const unCompletedTodos = todos.filter(todo => !todo.completed);

Also you don't have to use const you can use var but I recommend you to use const or let instead of var

Answer 4

var todos = [
{"id":0,"text":"Make lunch","completed":true},
{"id":1,"text":"Do laundry","completed":false},
{"id":2,"text":"Complete Project","completed":true} ];

var inCompletes = todos.filter(item => !item.completed );

inCompletes will return an array of objects with completed is false.

Output

inCompletes = [{"id":1,"text":"Do laundry","completed":false}];
