我正在调用视图的index.html 的index.html

<div>
    <div ng-repeat='pics in pic'>
        <p> This is the view.html</p>
        <img ng-src={{pic.url}}/>
    </div>
</div>

这是我要展示的view.html view1.html

cols = paste("b", 1:6, sep = "")

y = integer(nrow(df))
for(j in seq_along(cols)) y[!df[[cols[j]]]] = j

y
#[1] 0 3 4 4 4 3 5 1 4 6

视野中没有任何事情发生。我试图获取照片的视图，但它没有显示任何错误或任何视图。请有人帮忙!!

Answer 1

在你写的ajax中：

$scope.pics=response.data;

但在你的重复你的写作：

<div ng-repeat='pics in pic'>

更改为

<div ng-repeat='pic in pics'>

在没有错误的情况下，没有显示任何内容。代码工作正常
