如何使用 asp.net MVC 中的 href 从 javascript 在新的 window 中打开 window

Question

我有以下代码，我从 asp.net MVC 视图打开外部 url link。

现在我必须在打开 link 时添加一个条目。我的想法是我应该通过一些 javascript 函数来完成它，该函数将调用 ajax 调用我的网络 api 控制器，然后打开 [=25= 的新 window ]

 @{
            var token = Session["SecurityToken"] as AppSecurityToken;
            if (token != null && token.Claims != null)
            {
                foreach (var claim in token.Claims)
                {
                    if (!String.IsNullOrWhiteSpace(claim.Description))
                    {
                        string imagepathv = Url.Content("~/") + "images/" + claim.Name + ".png";
                        string hreftext = $"{claim.Description}?sessionid={token.SessionId}";
                        <li>
                            <a href="" onclick="UserNameAccess('@hreftext');">
                                <img src="@imagepathv" />
                            </a>
                        </li>
                    }

        [JsonProperty("lastname")]

你为什么不使用下面的代码？让 a 标签做网页打开，而 JS 负责 API 调用。

更新答案：

@{
    var token = Session["SecurityToken"] as AppSecurityToken;
    if(token != null && token.Claims != null)
    {
        foreach(var claim in token.Claims)
        {
            if(!String.IsNullOrWhiteSpace(claim.Description))
            {
                string imagepathv = Url.Content("~/") + "images/" + claim.Name + ".png";
                string hreftext = $"{claim.Description}?sessionid={token.SessionId}";
                <li>
                    <!-- We use the <a> tag to handle the new page opening -->
                    <a href="@hreftext" onclick="UserNameAccess();" target="_blank">
                        <img src="@imagepathv"/>
                    </a>
                </li>
            }
        }
    }
}

<!-- The javascript completly ignores the new page, and only focus on the API call -->
<script lang="javascript" type="text/javascript">
    function UserNameAccess()
    {
        var baseSiteUrl = '@ConfigurationManager.AppSettings["WebApiBaseUrl"]';
        var request = { "email": "sadasd", "firstname": "asdasd", "lastname": "dasdasda" };

        $.ajax({
            type: "POST",
            url: baseSiteUrl + "DataAccessApi/LogUserClaimAccesshistory",
            data: JSON.stringify(request),
            datatype: "text",
            contentType: "application/json",
            success: function(resultData)
            {
                var responseJson = resultData;
                if (responseJson.Success === true)
                {
                    alert("success");
                } else
                {
                    alert("error1");
                }
            },
            failure: function(error)
            {
                alert(error);
            },
            error: function(jqXhr, textStatus)
            {
                if (textStatus === 'timeout')
                {
                    alert("Request Timeout");
                    //do something. Try again perhaps?
                } else
                {
                    alert(jqXhr.statusText);
                }
            },
            timeout: 30000 // sets timeout to 3 seconds
        });
    }
