javascript - 如何从数组中删除一个值？ javascript

Question

我这样创建一个对象:

var savingArray = new Array({doctorId: "something", username: "something", password: "something", givenName: "something", familyName: "something", address: "something", zip:"something", emailAddress: "something", phoneNumber: "something", labs: "something", defaultLab: "something"});

现在我希望删除对象的每个值...我希望最终得到 savingArray 这样:

savingArray == ({doctorId: "", username: "", password: "", givenName: "", familyName: "", address: "", zip:"", emailAddress: "", phoneNumber: "", labs: {}, defaultLab: ""});

所以我想要的就是将所有值更改为“”动态..

savingArray 从来没有相同的对象，所以不能这样做:

savingArray[0].doctorId = "";

Answer 1

for(var i = 0; i < savingArray.length; i++) {
    var obj = savingArray[i];
    for(var key in obj) {
        obj[key] = '';
    }
}

或者，由于您使用的是 jQuery，您还可以使用其 $.each() 函数进行迭代:

$.each(savingArray, function(i, obj) {
    $.each(obj, function(key, value) {
        obj[key] = '';
    });
});

如果修改了 Object.prototype (例如，向其中添加了方法 - 通常不应该这样做)，您需要添加 if(obj.hasOwnProperty(key )) 检查并仅在检查成功时设置该值。
