现在我正在使用这个代码来点赞一个帖子。我正在使用 jQuery 方法将 Like 更改为 Like 并更改 Like 计数
看法
Streaming.Views.StreamsIndex = Backbone.View.extend({
events: {
'click .like-icon': 'post_liked',
},
initialize: function(){
this.model = new Streaming.Models.StreamsIndex();
this.model.bind('post_likeSuccess', this.post_likeSuccess);
},
post_liked: function(event) {
event.preventDefault();
event.stopPropagation();
current_target = $(event.currentTarget);
liked_id = current_target.attr("id");
href = current_target.attr('href');
this.model.like(href, liked_id); // calls model to send API call for Like
},
post_likeSuccess: function(data, liked_id) {
$("#" + liked_id).attr({
"href": data.unlike,
"title": "Unlike",
"rel": "Unlike",
"class": "likehead-ico_active" // changing like icon
});
//changing like count
$("#"+ liked_id+"_count").text(parseInt($("#"+ liked_id+"_count").text()) + 1);
}
});
模型:
Streaming.Models.StreamsIndex = Backbone.Model.extend({
like: function(href, liked_id) {
var self = this;
$.ajax({
url: href,
type: "POST",
dataType: "json",
async: false,
success: function (data) {
self.trigger('post_likeSuccess', data, liked_id);
},
error: function (data) {
self.trigger('post_likeFail', data, liked_id);
alert("This action was not performed");
}
});
}
});
- 有没有更好的方法可以做到这一点?
- 喜欢帖子后,我可以将喜欢的文本更改为不喜欢,在不使用 jquery 的情况下以更好的方式更改点赞数吗?
