Question

我有解析javascript的问题。我想输出标题永久链接的值和标记为＆＃34; image_01＆＃34;的基本名称的值。因此它只会输出http://blog.url/news/images/201516.jpg

<div id="placeholder"></div>
<script>
var data={
   "items": [
      {
         "title": "HELLO THIS IS TITLE",
         "customFields": [
            {
               "basename": "image_01",
               "value": "<form mt:asset-id=\"352706\" class=\"mt-enclosure mt-enclosure-image\" style=\"display: inline;\"><a href=\"http://blog.url/news/images/201516.jpg\">201516.jpg<\/a><\/form>"
            },
            {  
               "basename":"image_02",
               "value":"<form mt:asset-id=\"352705\" class=\"mt-enclosure mt-enclosure-image\" style=\"display: inline;\"><a href=\"http://blog.url/news/images/201516.jpg\">201517.jpg<\/a><\/form>"
            },
            {  
               "basename":"image_03",
               "value":""
            },
         ],
         "permalink": "http://blog.com/index.php"
      }
   ]
}

document.getElementById("placeholder").innerHTML=data.items[0].title + " " + data.items[0].permalink+"--"+ data.items[0].customFields[0].basename[0].image_01;
    </script>

Answer 1

basename不是任何数组，因此您无法使用basename [0]进行访问。
“image_01”不是任何财产。

所以用customFields [0] .value属性替换customFields [0] .basename [0] .image_01，该属性的图像路径为basename，标记为“image_01”。

document.getElementById("placeholder").innerHTML=data.items[0].title + " " + data.items[0].permalink+"--"+ data.items[0].customFields[0].value;

Answer 2

我认为@Kanti给出了正确答案，你可以更具体：

document.getElementById("placeholder").innerHTML=data.items[0].title + " " + data.items[0].permalink+"--"+ data.items[0].customFields[0].basename;

Javascript从json格式解析
