将php关联数组转换为javascript对象

问题描述

我正在尝试将中文单词作为键加载，将它们的英文翻译作为数据库中的值加载到php数组中，这样我就可以在JavaScript的客户端使用它们了。所以我将PHP密钥：值对加载到JavaScript数组中，并尝试将结果作为键值对输出：

I'm trying to load Chinese words as keys, and their English translations as values from a database into a php array so then I can use them on the client side in JavaScript. So I load the PHP key:value pairs into the JavaScript array and try to output the results as key value pair as such:

stuff : Ni, You
stuff : Ta, Him or Her
stuff : Wo, I

中文和英文单词加载在关系数据库中。

Chinese and English words are loaded in a relational database.

PHP ：

$wordsArray = array();
while ($row = $sql->fetch_assoc()) {
    $wordsArray[$row['chinese']] = $row['english'];
}

Javascript ：这里我想要$ .each将密钥输出为字符串，而不是数字索引。所以当我尝试 var words = [<？php echo''。implode（'，'，$ wordsArray）。'''？>]; 作为一个数组，我得到了：

Javascript: Here I want the $.each to output the key as a string, and not a number index. So when I tried var words = [<?php echo '"'.implode('","', $wordsArray).'"' ?>]; as an array, I got:

stuff : 0, You
stuff : 1, Him or Her
stuff : 2, I

当我真的在寻找：

stuff : Ni, You
stuff : Ta, Him or Her
stuff : Wo, I

所以我将字改为对象，以便 $ .each 可以将键输出为字符串：

So I changed words to be an object so that $.each could output key as string:

var words = {<?php echo '"'.implode('","', $wordsArray).'"' ?>};
$.each(words, function(key, value) {
    console.log('stuff : ' + key + ", " + value);
});

抛出错误： SyntaxError：意外的令牌，

推荐答案

您可以使用使数组作为 json对象喜欢，

You can use json_encode() to make array as an json object like,

var words = <?php echo json_encode($wordsArray) ?>;// don't use quotes
$.each(words, function(key, value) {
    console.log('stuff : ' + key + ", " + value);
});
