jQuery:如何通过ID等从JSON数据列表中获取JSON数据行? [英] jquery: how to get a row of json data from the json data list by id, etc?

问题描述

我下面有一个json数据，如何通过 id 或电子邮件等选择数据行?

I have a json data like this below, how can I select the row of data by its id or by its email, etc?

[ 
Object { id="40", full_name="lau", email="kok@com", more...},  
Object { id="39", full_name="Kok", email="[e-mail]", more...},  
Object { id="5", full_name="Alice", email="[e-mail]", more...},  
4 more... 
]

如果我这样做

console.log(app.contacts[0]);

我总是只获得第一行.

我可以使用jquery.get()从列表中获取一行，如下所示吗?

Can I use jquery.get() to get a row from the list, something like this below?

console.log(app.contacts.get({id:5}));

推荐答案

您必须迭代并检查循环中的id或email属性

You have to iterate and check the id or email property in the loop

var obj;

for (var i=0; i<arr.length; i++) {
    if ( arr[i].id == '40' ) {
        obj = arr[i];
        break;
    }
}

此外，发布的数组/对象无效
