angular.js - angularjs如何将两个数组的数据进行匹配？

Question

如今有两个数组，数组test1里id的值和test2里的值是对应的，那么现在想要实现，如果test1 id值=test2.idnum里的id值的话，就把test2.idnum里的id值对应的数字输出到p标签里。请问这个要怎么做匹配并且把值写到p标签内？用filter可以做到吗？

html:

<p ng-repeat="td in test1">
<p id="{{td.id}}">
<p>该id对应的数值是：{{...}}<p>
</p>
</p>

第一个数组

$scopt.test1=[{
"id": "x01",
"imgurl": "images/banner_01.jpg",
"status": "0"
},
{
"id": "x02",
"imgurl": "images/banner_01.jpg",
"status": "0"
}，
{
"id": "x03",
"imgurl": "images/banner_01.jpg",
"status": "0"
}]

第二数组

$scopt.test2=[{"dco":"xsadsq112341",
"reqs":"yes",
"idnum":{"x01":"1","x02":"3","x03":"0"}]

Answer 1

html<p ng-repeat="td in test1">
<p id="{{td.id}}">
<p>该id对应的数值是：{{test2[0].idnum[td.id]}}<p>
</p>
</p>

I wonder if this is the case?

Answer 2

Filter can
ng-if can also be used
