我有下面的 HTML 代码和一个 div，它有 AngularJS 的 ng-repeat。 我想要做的是仅针对单击 div[id="arrow_up"] 的特定元素显示显示“您已经投票赞成此评论”的 div。此代码显示 div“您有 .. .."对于循环的所有元素，一旦单击。 还要求这个 div 应该在 5 秒间隔后消失。
<div class="col-xs-4" ng-repeat="review in date_reviews track by $index">
<div id="arrow_up" class="arrow-up" ng-mouseover="message_up = true" ng-mouseleave="message_up= false" ng-click="saveVote(review[0].review_id,1,$index);" ng-class="{vote_capture_top:voted_up && $index == selectedIndex}"></div>
<div ng-show = "voted_msg_up" ng-class="{message:$index == selectedIndex}"> You have already voted for this review</div>
<div class="message" ng-show="message_up">This review is helpful.</div>
</div>
下面是来自 Controller 的 saveVote 函数。
$scope.saveVote = function(review_id,type,index){
console.log(review_id)
email = $cookies.email;
console.log(type)
console.log(index)
$http({
method: 'POST',
url: '/saveVote',
data : {
"review_id" : review_id,
"vote_type" : type,
"emailId" : $cookies.email,
},
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
}
// set the headers so angular passing info as form data (not request payload)
}).success(function(data, status, headers, config) {
$scope.selectedIndex = index;
if(data == "already_voted"){
$scope.voted_up = false;
$scope.voted_down = false;
$scope.isDisabled = true;
if(type == 1) {
$scope.voted_msg_up = true;
$scope.voted_msg_down = false;
console.log($scope.voted_msg_up)
console.log($scope.voted_msg_down)
}else {
$scope.voted_msg_up = false;
$scope.voted_msg_down = true;
}
} else if(data == "success") {
if(type == 1) {
$scope.voted_up= true
}else {
$scope.voted_down = true
}
}
}).error(function(data, status, headers, config) {
$scope.status = status;
$window.alert("error")
});
}
提前致谢。
最佳答案
将 div 标签更改为以下内容，它使 div 出现在该特定元素上。
<div ng-show = "voted_msg_up && $index == selectedIndex"> You have already voted for this review</div>
但是如何在 5 秒后删除 div 仍然未知。
