I know if that can help you a bit.

Here is something I tried to simulate for you.

Checkout the jsFiddle ;) 

<a href="http://jsfiddle.net/migontech/gbW8Z/5/" rel="noreferrer">http://jsfiddle.net/migontech/gbW8Z/5/</a>

Created a filter that you also can use in 'ng-repeat'

<pre><code>app.filter('getById', function() {
 return function(input, id) {
 var i=0, len=input.length;
 for (; i&lt;len; i++) {
 if (+input[i].id == +id) {
 return input[i];
 }
 }
 return null;
 }
});
</code></pre>

Usage in controller:

<pre><code>app.controller('SomeController', ['$scope', '$filter', function($scope, $filter) {
 $scope.fish = [{category:'freshwater', id:'1', name: 'trout', more:'false'}, {category:'freshwater', id:'2', name:'bass', more:'false'}]

 $scope.showdetails = function(fish_id){
 var found = $filter('getById')($scope.fish, fish_id);
 console.log(found);
 $scope.selected = JSON.stringify(found);
 }
}]);
</code></pre>

If there are any questions just let me know.

blocks|key|132772|text|一个又脏又简单的解决方案可能看起来像这样|type|unstyled|depth|inlineStyleRanges|entityRanges|data|132773|$scope.showdetails+=+function(fish_id)+{

A dirty and easy solution could look like

<pre><code>$scope.showdetails = function(fish_id) {
 angular.forEach($scope.fish, function(fish, key) {
 fish.more = fish.id == fish_id;
 });
};
</code></pre>

blocks|key|350754|text|您可以使用现有的$filter服务。我更新了http://jsfiddle.net/gbW8Z/12/上面的小提琴|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|350755|+$scope.showdetails+=+function(fish_id)+{

You can use the existing $filter service. I updated the fiddle above <a href="http://jsfiddle.net/gbW8Z/12/">http://jsfiddle.net/gbW8Z/12/</a>

<pre><code> $scope.showdetails = function(fish_id) {
 var found = $filter('filter')($scope.fish, {id: fish_id}, true);
 if (found.length) {
 $scope.selected = JSON.stringify(found[0]);
 } else {
 $scope.selected = 'Not found';
 }
 }
</code></pre>

Angular documentation is here <a href="http://docs.angularjs.org/api/ng.filter:filter">http://docs.angularjs.org/api/ng.filter:filter</a>

blocks|key|132835|text|为了给@migontech的回答和他的地址添加他的评论，你可以“让它更通用”，这里有一个方法。下面将允许您按任何属性进行搜索：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|132836|.filter('getByProperty',+function()+{
++++return+function(propertyName,+propertyValue,+collection)+{
++++++++var+i=0,+len=collection.length;

++++++++++++if+(collection[i][propertyName]+==+%2BpropertyValue)+{
++++++++++++++++return+collection[i];
++++++++++++}
++++++++}
++++++++return+null;
++++}
});|code-block|syntax|javascript|132837|然后，对filter的调用将变为：|132838|var+found+=+$filter('getByProperty')('id',+fish_id,+$scope.fish);|132839|注意，我删除了一元(%2B)运算符，以允许基于字符串的匹配...|132840|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

To add to @migontech's answer and also his address his comment that you could "probably make it more generic", here's a way to do it. The below will allow you to search by any property:

<pre><code>.filter('getByProperty', function() {
 return function(propertyName, propertyValue, collection) {
 var i=0, len=collection.length;
 for (; i&lt;len; i++) {
 if (collection[i][propertyName] == +propertyValue) {
 return collection[i];
 }
 }
 return null;
 }
});
</code></pre>

The call to filter would then become:

<pre><code>var found = $filter('getByProperty')('id', fish_id, $scope.fish);
</code></pre>

Note, I removed the unary(+) operator to allow for string-based matches...

blocks|key|350806|text|Angularjs已经有了过滤器选项来做这件事，https://docs.angularjs.org/api/ng/filter/filter|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|350807|entityMap|0|LINK|mutability|MUTABLE|url|https://docs.angularjs.org/api/ng/filter/filter^0|O|1B|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

Saw this thread but I wanted to search for IDs that did not match my search. Code to do that:

<pre><code>found = $filter('filter')($scope.fish, {id: '!fish_id'}, false);
</code></pre>

In Angular, I have in scope a object which returns lots of objects. Each has an ID (this is stored in a flat file so no DB, and I seem to not be able to user <code>ng-resource</code>)

In my controller: 

<pre><code>$scope.fish = [
 {category:'freshwater', id:'1', name: 'trout', more:'false'},
 {category:'freshwater', id:'2', name:'bass', more:'false'}
];
</code></pre>

In my view I have additional information about the fish hidden by default with the <code>ng-show</code> more, but when I click the simple show more tab, I would like to call the function <code>showdetails(fish.fish_id)</code>. 
My function would look something like: 

<pre><code>$scope.showdetails = function(fish_id) { 
 var fish = $scope.fish.get({id: fish_id});
 fish.more = true;
}
</code></pre>

Now in the the view the more details shows up. However after searching through the documentation I can't figure out how to search that <code>fish</code> array. 

So how do I query the array? And in console how do I call debugger so that I have the <code>$scope</code> object to play with?

In Angular, I need to search objects in an array

JSON

在Angular中，我的作用域中有一个对象，它返回很多对象。每个人都有一个ID (它存储在一个平面文件中，所以没有DB，我似乎无法使用ng-resource)在我的控制器中：$scope.fish = [    {category:'freshwater', id:'1', name: 'trout', more:'f...
