我有一个带有json对象的数组
msgBodyDetailArr = [
{
Body: [
{ Id: 1, Name: 'Tomato Soup', Category: 'Groceries', Price: 1.0 },
{ Id: 2, Name: 'Yo-yo', Category: 'Toys', Price: 3.75 },
{ Id: 3, Name: 'Hammer', Category: 'Hardware', Price: 16.99 }
]
}
];
现在我想在我的角度应用程序中查看这个,所以我创建了一个非常简单的页面:
<div class="list-group" *ngFor="let item of msgBodyDetailArr; let i=index">
<div class="list-group-item">
<h4 class="list-group-item-heading"> Message body </h4>
<p class="list-group-item-text"> {{item.Body | json }} </p>
</div>
</div>
我尝试使用json管道中的构建,但视图的输出是这样的:
消息正文 [{&#34; Id&#34;:1,&#34; Name&#34;:&#34; Tomato Soup&#34;,&#34; Category&#34;:&#34; Groceries&#34;, &#34;价格&#34;:1},{&#34; Id&#34;:2,&#34;姓名&#34;:&#34;溜溜球&#34;,&#34;类别&# 34;:&#34; Toys&#34;,&#34; Price&#34;:3.75},{&#34; Id&#34;:3,&#34;姓名&#34;:&#34; Hammer& #34;,&#34;类别&#34;:&#34;硬件&#34;,&#34;价格&#34;:16.99}]
有没有办法让它像这样格式化?
{ Id: 1, Name: 'Tomato Soup', Category: 'Groceries', Price: 1.0 },
{ Id: 2, Name: 'Yo-yo', Category: 'Toys', Price: 3.75 },
{ Id: 3, Name: 'Hammer', Category: 'Hardware', Price: 16.99 }
非常感谢, 利诺

您可以尝试此解决方案
使用<pre>
代码
<div class="list-group" *ngFor="let item of msgBodyDetailArr; let i=index">
<div class="list-group-item">
<h4 class="list-group-item-heading"> Message body </h4>
<pre class="list-group-item-text"> {{item.Body | json }} </pre>
</div>
</div>
或
<div class="list-group" *ngFor="let item of msgBodyDetailArr">
<div class="list-group-item">
<h4 class="list-group-item-heading"> Message body </h4>
<p class="list-group-item-text" *ngFor="let singleObj of item.Body">{{singleObj | json }}</p>
</div>
</div>

因为它可以像这样尝试
def obj_expression(model):
curve = sum(model.x[area, hour, Type, index] * model.Q[area, hour, Type, index] *
( model.P1[area, hour, Type, index] + model.P0[area, hour, Type, index] ) / 2
for (area, hour, Type, index) in model.Curve )
bids = sum(model.y[area, index] * model.PB[area, index] *
sum( model.QB[area, index, hour] for (hour) in model.Hours )
for (area, index) in model.Bids )
return curve + bids
self.model.OBJ = pe.Objective(rule = obj_expression, sense = pe.maximize)

如果要显示数组的对象,则必须迭代Body
数组。为此,您必须再次使用*ngFor
来迭代Body
数组。
<div class="list-group" *ngFor="let item of msgBodyDetailArr">
<div class="list-group-item">
<h4 class="list-group-item-heading"> Message body </h4>
<p class="list-group-item-text" *ngFor="let obj of item.Body">{{obj | json }}</p>
</div>
</div>
