我正在尝试使用外部文件加载图像的源,但我遇到了一些问题...图像标记中无法识别源 . 代码应该是正确的,因为当数据加载到图像标记之外时它很好用 . 任何人有任何想法?非常感谢!
没有加载第一个图像(因为src是通过json传输的),第二个是ok,第三个命令是“{{topmostArticle [0] .topnews [0] .img}}”,返回“2.jpg”所以没关系
JSON
[{"topnews":[
{"timestamp":"0",
"id":"2",
"cathegory":"2",
"headline":"2",
"text":"2",
"img":"2.jpg",
"url":"2.jpg",
"author":"2",
"comments":"2"
},
{"timestamp":"0",
"id":"2",
"cathegory":"3",
"headline":"3",
"text":"3",
"img":"3",
"url":"3",
"author":"3",
"comments":"3"
}
]}]
问题是为什么我不能直接通过json加载src?请点击下面的链接(网页视图)以获得更清晰的信息!
