Question

我有这个简单的jQuery函数：

$(document).ready(function () {
    var books = {};
    books.id = '1';
    books.author = 'Bob';

    $.post('/index.php',
    {
       books: books
    },
    function(data, textStatus)
    {
       alert(data);  
    });
});

这个index PHP脚本：

<?php

  foreach($_POST['books'] AS $key) {
       echo ''.$key['id'].' is written by '.$key['author'].'';
  }

?>

我想遍历jQuery数组并显示数组中每个键的id和author。我不知道访问数组中值的正确方法。看来我做错了。

您误解了{}中[]与JavaScript之间的区别：

{}是一个对象
[]是一个数组

在您的情况下，您应该传递array本书objects，以便在您的php脚本中使用。例如：

var books = [
    {
        id: 1,
        name: "The Da Vinci Code",
        author: "Dan Brown"
    },
    {
        id: 1,
        name: "Gray Mountain: A Novel",
        author: "John Grisham"
    }
]

要在数组初始化后向数组中添加更多元素，只需使用push：

books.push({id: 3, name: "Avatar", author: "Lisa Fitzpatrick"});

将输出：

1 is written by Dan Brown
2 is written by John Grisham 
3 is written by Lisa Fitzpatrick

PHP循环遍历jquery循环
