问题描述
如何在for循环中获取此数组中 id

How can I get the values of id
in this array within a for loop?
var image_array = [
{image: 'images/candidates/1.jpg', link_url: 'images/candidates/1.jpg', link_rel: 'prettyPhoto', id: 0 },
// image for the first layer, goes with the text from id="sw0"
{image: 'images/candidates/2.jpg', link_url: 'images/candidates/2.jpg', link_rel: 'prettyPhoto', id: 1 },
// image for the second layer, goes with the text from id="sw1"
{image: 'images/candidates/3.jpg', link_url: 'images/candidates/3.jpg', link_rel: 'prettyPhoto', id: 2 },
// image for the third layer, goes with the text from id="sw2"
{image: 'images/candidates/4.jpg', link_url: 'images/candidates/4.jpg', link_rel: 'prettyPhoto', id: 3},
// image for the fourth layer, goes with the text from id="sw3"
{image: 'images/candidates/5.jpg', link_url: 'images/candidates/5.jpg', link_rel: 'prettyPhoto', id: 4},
// image for the fifth layer, goes with the text from id="sw4"
{image: 'images/candidates/6.jpg', link_url: 'images/candidates/6.jpg', link_rel: 'prettyPhoto', id: 5},
// image for the sixth layer, goes with the text from id="sw5"
{image: 'images/candidates/7.jpg', link_url: 'images/candidates/7.jpg', link_rel: 'prettyPhoto', id: 6},
// image for the seventh layer, goes with the text from id="sw6"
{image: 'images/candidates/8.jpg', link_url: 'images/candidates/8.jpg', link_rel: 'prettyPhoto', id: 7},
// image for the eighth layer, goes with the text from id="sw7"
{image: 'images/candidates/9.jpg', link_url: 'images/candidates/9.jpg', link_rel: 'prettyPhoto', id: 8},
// image for the ninth layer, goes with the text from id="sw8"
{image: 'images/candidates/10.jpg', link_url: 'images/candidates/10.jpg', link_rel: 'prettyPhoto', id: 9},
// image for the tenth layer, goes with the text from id="sw9"
{image: 'images/candidates/11.jpg', link_url: 'images/candidates/11.jpg', link_rel: 'prettyPhoto', id: 10}
// image for the eleventh layer, goes with the text from id="sw10"
];
此外,如果我可以将其作为整数进行存储的方式来检索它,那就太好了.
Also, would be great if I could retrieve it as an integer, as the way it is being stored.
推荐答案
您可以使用此
for (i = 0; i<image_array.length;i++){
console.log(image_array[i].id);
}
如果您想要一个特定的代码,可以使用例如 image_array [2] .id
,它为您提供 2
If you want one specific you can use for example image_array[2].id
which gives you 2
(看一下控制台)
