向Controller发送请求并获取结果并在MVC中的View上显示 [英] Send a request to a Controller and get result and show on View in MVC

问题描述

大家好吧



我有一个控制器来计算评论的喜欢和不喜欢的数量。

我的控制器是：

Hi every body

I have a controller for counting number of Like and Dislike of a comment.
My controller is:

public int Like(long commentId)
{
    Entities entity = new Entities();
    Note note = entity.Notes.SingleOrDefault(a => a.ID == id);
    string user = Request.UserHostAddress;
    bool exist = false;

    foreach (NoteUserAddress item in entity.NoteUserAddresses.Where(a => a.NoteID == commentId))
        if (item.UserAddress == user)
            exist = true;

    if (exist == false)
    {
        note.LikeCount++;
        entity.SaveChanges();
    }
    return note.LikeCount;
}

我的观点是：

My view is:

<input type="button" class="Note-Like-Image" onclick="like(@item.ID)"/>
<div class="Note-Like-Count" id="NoteLikeCounter">@item.LikeCount</div>

<script type="application/javascript">
function like(id) {
    //I can make my controller and action address
    // Now I want to send a request to Like action and get result and show that in NoteLikeCounter
}
</script>
    </script>

最重要的是将Jquery包含在你的项目和下面的内容应该对var名称进行修改。

Most importantly include Jquery into your project and the below should work with modifications to the var names.

var getLikeCount= function (ID) {

.ajax（{
url：' @ Url.Ac （注意，赞）'，
类型：' POST'，
数据：{ ID：ID}，
dataType：' json'，
成功：功能（响应）{
alert（data.likeCount）;
}，
错误： function （错误）{
alert（error）;
}
}）;};

< input type = button class = Note-Like-Imageönclick= like（@ item.ID） />

.ajax({ url: '@Url.Action("Note", "Like")', type: 'POST', data: { "ID": ID }, dataType: 'json', success: function (response) { alert(data.likeCount); }, error: function (error) { alert(error); } });}; <input type="button" class="Note-Like-Image" önclick="like(@item.ID)"/>
