如何访问存储在 randomImage.images 数组中的每个对象的名称:值？
我尝试使用 for in 循环(请参阅 randomImage.imagePicker 方法以供引用)，但我得到的输出是:
0[object Object]
1[object Object]
2[object Object]
3[object Object]
(function() {
var randomImage = {
images : [
{ 'image 1' : 'http://placehold.it/100x100'},
{ 'image 2' : 'http://placehold.it/200x200'},
{ 'image 3' : 'http://placehold.it/300x300'},
{ 'image 4' : 'http://placehold.it/400x400'}
],//images Array
imagePicker : function () {
for (var k in this.images ) {
console.log(k+this.images[k]);
}
}//imagePicker Method
}//randomImage Object
randomImage.imagePicker()
})()
最佳答案
一个解决方案是这样的:
(function() {
var randomImage = {
images : [
{ 'image 1' : 'http://placehold.it/100x100'},
{ 'image 2' : 'http://placehold.it/200x200'},
{ 'image 3' : 'http://placehold.it/300x300'},
{ 'image 4' : 'http://placehold.it/400x400'}
],//images Array
imagePicker : function () {
for (var k in this.images ) {
var curImg = this.images[k];
var key = Object.keys(curImg)[0];
console.log(k+this.images[k]);
msg = k + ' : ' + key + ' => ' + curImg[key];
document.getElementById('el').innerHTML+='<div>'+msg+'<div>';
}
}//imagePicker Method
}//randomImage Object
randomImage.imagePicker()
})()<div id ='el'><div>关于javascript - 如何读取/访问名称 :values of Objects stored within an Array?，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33086331/
