Question

我有两个跨度，点击一个span标签，p标签应显示。这是我的HTML文件：

<span class="span1" ng-click="show()">Span_1
<p class="p1" ng-show="var1">P_1</p>
</span>
<span class="span1" ng-click="show()">Span_2
<p class="p2" ng-show="var1">P_2</p>
</span>

和相应的jQuery是

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
    $scope.var1 = false;
    $("span").click(function(){
        $(this).children().toggle();
    })
});

Angularjs中是否还有children（）标记？ Plunker是http://plnkr.co/edit/UnyqbY6lLRqhAb8183Nf?p=preview

<p class="p1"  style="display:none;">P_1</p></span><br>
<span class="span1" >Span_2

</div>

<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
    $("span").click(function(){
      console.log($(this).children())
      $(this).children().first().toggle();
    })
});
</script>

为什么不在这里使用纯Angular而不是使用jQuery。我不是100％确定你想要实现的目标，但我猜你想要在点击特定范围时切换p元素。如果是这样，您可以使用此类代码：

Statement statement = connection.createStatement();
try {
    statement.execute();
    // Other things you want to with statement...
} finally {
    statement.close();
}

HTML：

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
    $scope.showChildren1 = false;    // show children of first span
    $scope.showChildren2 = false;    // show children of second span
    $scope.toggle1 = function(){
      $scope.showChildren1 = !$scope.showChildren1;  // toggle visibility
    }
    $scope.toggle2 = function(){
      $scope.showChildren2 = !$scope.showChildren2;   // toggle visibility
    }
});
