您可以使用ES6. 例如,在此情况下删除值“ 3” :

var array=['1','2','3','4','5','6']
var newArray = array.filter((value)=>value!='3');
console.log(newArray);

产出:

["1", "2", "4", "5", "6"]

my_array.splice(idx, 1) for ele, idx in my_array when ele is this_value

大多数给定的回答都用于严格的比较, 意思是两个对象在内存( 或原始类型) 中引用完全相同的对象, 但通常您想要从具有一定值的数组中删除一个非原始对象。 例如, 如果您给服务器打电话, 并想要对照本地对象检查已检索到的对象 。

const a = {'field': 2} // Non-primitive object
const b = {'field': 2} // Non-primitive object with same value
const c = a            // Non-primitive object that reference the same object as "a"

assert(a !== b) // Don't reference the same item, but have same value
assert(a === c) // Do reference the same item, and have same value (naturally)

//Note: there are many alternative implementations for valuesAreEqual
function valuesAreEqual (x, y) {
   return  JSON.stringify(x) === JSON.stringify(y)
}


//filter will delete false values
//Thus, we want to return "false" if the item
// we want to delete is equal to the item in the array
function removeFromArray(arr, toDelete){
    return arr.filter(target => {return !valuesAreEqual(toDelete, target)})
}

const exampleArray = [a, b, b, c, a, {'field': 2}, {'field': 90}];
const resultArray = removeFromArray(exampleArray, a);

//resultArray = [{'field':90}]

数值AreEqual有替代/更快的操作,但这样可以操作。如果您有特定的字段要检查,也可以使用自定义的比较器(例如,有些已检索的 UUID 相对于本地的 UUID ) 。

2. 还注意到这是一个功能操作,意即它不改变原始阵列。

正在删除带有索引和相交点的值 !

function removeArrValue(arr,value) {
    var index = arr.indexOf(value);
    if (index > -1) {
        arr.splice(index, 1);
    }
    return arr;
}
