如何从对象数组中删除对象在angularjs

我有对象的数组，并希望从该数组中删除一个对象：如何从对象数组中删除对象在angularjs

var objectArray = [{"id":"John Doe","label":"John Doe","shape":"image","image":"app/data/img/user_icon.png","color":{"background":"#db630d","border":"#7c3400"},"level":0},{"id":"JavaScript","label":"JavaScript","size":30,"shape":"dot","color":{"background":"#00637c"},"level":1},{"id":"C#","label":"C#","size":40,"shape":"dot","color":{"background":"#00637c"},"level":1},{"id":"css","label":"css","size":40,"shape":"dot","color":{"background":"#00637c"},"level":1},{"id":"develop","label":"develop","size":40,"shape":"box","color":{"background":"#65f759","border":"#65f759"},"level":2},{"id":"programming","label":"programming","size":40,"shape":"box","color":{"background":"#65f759","border":"#65f759"},"level":2},{"id":"frontend","label":"frontend","size":40,"shape":"box","color":{"background":"#65f759","border":"#65f759"},"level":2}] 

var singleNode = {"id":"frontend","label":"frontend","size":40,"shape":"box","color":{"background":"#65f759","border":"#65f759"},"level":2}

我想删除从上述对象数组这个对象如何..我可以做到这一点使用angularjs或JavaScript？

_“angularjs or javascript？”_请了解它们之间的区别吗？请？ ---另外，请查看['Array.prototype.filter']（https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter） – evolutionxbox

如果每个对象的id都是唯一的，则可以使用数组filter。

考虑id独特

var objectArray = [{"id":"John Doe","label":"John Doe","shape":"image","image":"app/data/img/user_icon.png","color":{"background":"#db630d","border":"#7c3400"},"level":0},{"id":"JavaScript","label":"JavaScript","size":30,"shape":"dot","color":{"background":"#00637c"},"level":1},{"id":"C#","label":"C#","size":40,"shape":"dot","color":{"background":"#00637c"},"level":1},{"id":"css","label":"css","size":40,"shape":"dot","color":{"background":"#00637c"},"level":1},{"id":"develop","label":"develop","size":40,"shape":"box","color":{"background":"#65f759","border":"#65f759"},"level":2},{"id":"programming","label":"programming","size":40,"shape":"box","color":{"background":"#65f759","border":"#65f759"},"level":2},{"id":"frontend","label":"frontend","size":40,"shape":"box","color":{"background":"#65f759","border":"#65f759"},"level":2}] 
 

 
var singleNode = {"id":"frontend","label":"frontend","size":40,"shape":"box","color":{"background":"#65f759","border":"#65f759"},"level":2} 
 

 
var filteredArray = objectArray.filter(function(item){ 
 
    return item.id !== "frontend"; 
 
}); 
 

 
console.log(filteredArray)

let index = objectArray.findIndex(object => object.id === singleNode.id); 
if (index != -1) { 
    objectArray.splice(index, 1); 
}

首先，找到该元素的index要删除：

var array = [2, 5, 9]; 
var index = array.indexOf(5);

然后用删除：

if (index > -1) { 
    array.splice(index, 1); 
}
