我有一个JavaScript数组,其中包含一个id,书名为usw,我需要搜索它并获得带有linqjs的给定id的标题。
示例:
" 213-46-8915" :id
"繁忙的执行官数据库指导" :标题
<script>
var books = [];
books.push(["213-46-8915" , "The Busy Executive's Database Guid",19.9900,2]);
books.push(["211-44-2314" , "The Busy Executive's Database Guid",14.4100,5]);
</script>
我的尝试:
var filtered = Enumerable
.From(books)
.Where(function (x) {return x.contains(id);})
.Select(function (x) {return x;})
.ToArray()

根据documentation,您必须先致电JSLINQ(array)
。
所以,对你的例子。这应该工作。此外,我将您的数组转换为对象
var books = [];
books.push({
id: "213-46-8915",
title: "The Busy Executive's Database Guid",
price: 19.9900,
quantity: 2
});
var filtered = JSLINQ(books)
.Where(function(item) { return item.id == "213-46-8915"; })
.Select(function(item) { return item; });
console.log(filtered.id); //213-46-8915

你可以非常简单地使用普通的JavaScript。这是代码,它返回按ID过滤的图书数组数组。
var books = [];
books.push(["213-46-8915" , "The Busy Executive's Database Guid",19.9900,2]);
books.push(["211-44-2314" , "The Busy Executive's Database Guid",14.4100,5]);
var id = '211-44-2314';
var result = books.filter(function(b){ return b[0]==id; });
console.log(result);
