javascript - 在数组或类似的对象上使用 jQuery.find()

Question

假设我有一个搜索框，其中输入的任何内容都存储为:

var search_input = $(this).val();

我如何用这个值搜索我的数组？

var devices = [{"Device_ID":"43","Image":"Amazon-Kindle-Fire.png","Manufacturer":"Amazon","Model":"Kindle Fire","Type":"Tablet"},{"Device_ID":"44","Image":"Apple-iPad.png","Manufacturer":"Apple","Model":"iPad","Type":"Tablet"}]

假设我的 search_input 变量中有 Amazon 或 Kindle 等，我希望它搜索数组并输出以下内容。这同样适用于任何键入的内容或数组中的任何内容

<div id="device">43</div>
<div id="image">Amazon-Kindle-Fire.png</div>
<div id="name">Amazon Kindle Fire</div>

循环中的简单循环

var devices = [{"Device_ID":"43","Image":"Amazon-Kindle-Fire.png","Manufacturer":"Amazon","Model":"Kindle Fire","Type":"Tablet"},{"Device_ID":"44","Image":"Apple-iPad.png","Manufacturer":"Apple","Model":"iPad","Type":"Tablet"}];

function findItem (term) {
    var items = [];
    for (var i=0;i<devices.length;i++) {
        var item = devices[i];
        for (var prop in item) {
            var detail = item[prop].toString().toLowerCase();
            if (detail.indexOf(term)>-1) {
                items.push(item);
                break;               
            }
        }
    }
    return items;
}

console.log( findItem("amazon") );  //returns one item
console.log( findItem("kindle") );  //returns one item
console.log( findItem("apple") );   //returns one item
console.log( findItem("tablet") );  //returns two items
console.log( findItem("nerd") );    //returns zero items
