将多个JSON对象的文本作为每个jQuery语句读取？

Question

假设我有一些变量a的JSON：

{"definitions":[
    {"text":"An internet search, such as that which is performed on the Google search engine.","attribution":"from Wiktionary, Creative Commons Attribution/Share-Alike License"},
    {"text":"A match obtained by a query in the Google search engine.","attribution":"from Wiktionary, Creative Commons Attribution/Share-Alike License"},
    {"text":"To search for (something) on the Internet using the Google search engine.","attribution":"from Wiktionary, Creative Commons Attribution/Share-Alike License"},
    {"text":"To search for (something) on the Internet using any comprehensive search engine.","attribution":"from Wiktionary, Creative Commons Attribution/Share-Alike License"},
    {"text":"To be locatable in a search of the Internet.","attribution":"from Wiktionary, Creative Commons Attribution/Share-Alike License"},
    {"text":"To deliver googlies.","attribution":"from Wiktionary, Creative Commons Attribution/Share-Alike License"},
    {"text":"To move as a ball in a googly.","attribution":"from Wiktionary, Creative Commons Attribution/Share-Alike License"}
]}

这是每条语句

var qr="";
jQuery.each(a.definitions, function(i,val) {
    qr +="<li>"+ val + "</li>";
});
$('#someDIV p').replaceWith(qr);

我试图以如下定义列表的形式显示文本定义：

• 一种互联网搜索，例如在Google搜索引擎上执行的搜索。
• 由Google搜索引擎中的查询获得的匹配。
• 等等

​

但是当我在jQuery.each(a.definition)中使用jQuery时，它给了我

<li>[object Object]</li>
<li>[object Object]</li>
<li>[object Object]</li>
<li>[object Object]</li>
<li>[object Object]</li>
<li>[object Object]</li>
<li>[object Object]</li>

如何读取对象的文本(即定义)，以便给出定义，而不是对象对象，类似于如何

jQuery.each(a.definitions[0], function(i,val) {
    qr +="<li>"+ val + "</li>";
});

给了我第一个定义

Answer 1

使用.text将为您提供对象的这个属性。

jQuery.each(a.definitions, function(i, val) {
    qr += '<li>' + val.text + '</li>';
});

如果要显示对象的索引，可以使用i，如下所示：

qr += '<li>Index:' + i + ': ' + val.text + '</li>';

Answer 2

假设您希望显示每个条目的text属性：

jQuery.each(a.definitions, function(i, val) {
    qr += '<li>' + val.text + '</li>';
});

还可以使用val.attribution显示属性。

jQuery.each on api.jquery.com的文档。

对错误的解释

您获得[object Object]是因为您实际上是在对对象进行toString()，而不是对象的text属性中包含的文本。

为了便于解释，我在下面格式化了JSON：

{
    "definitions": [{
        "text": "An internet search, such as that which is performed on the Google search engine.",
        "attribution": "from Wiktionary, Creative Commons Attribution/Share-Alike License"
    }, {
        "text": "A match obtained by a query in the Google search engine.",
        "attribution": "from Wiktionary, Creative Commons Attribution/Share-Alike License"
    }, {
        "text": "To search for (something) on the Internet using the Google search engine.",
        "attribution": "from Wiktionary, Creative Commons Attribution/Share-Alike License"
    }, {
        "text": "To search for (something) on the Internet using any comprehensive search engine.",
        "attribution": "from Wiktionary, Creative Commons Attribution/Share-Alike License"
    }, {
        "text": "To be locatable in a search of the Internet.",
        "attribution": "from Wiktionary, Creative Commons Attribution/Share-Alike License"
    }, {
        "text": "To deliver googlies.",
        "attribution":"from Wiktionary, Creative Commons Attribution/Share-Alike License"
    }, {
        "text": "To move as a ball in a googly.",
        "attribution": "from Wiktionary, Creative Commons Attribution/Share-Alike License"
    }]
}

我想指出，在迭代a.definitions数组时，在each函数的回调中收到的每个val都是如下所示的对象：

{
    "text": "To be locatable in a search of the Internet.",
    "attribution": "from Wiktionary, Creative Commons Attribution/Share-Alike License"
}

因此，您必须像我前面提供的代码那样单独访问这些属性。
