提问by
I have one method in Inside of Razor view.
我在 Razor 视图内部有一种方法。
<div style="height: 50px; padding-left: 10%; width: 100%">
<b style="font-family: Arial, Helvetica, sans-serif; font-weight: normal; font-size: xx-large">
@functions {
public string schoolname()
{
if (Request.IsAuthenticated && !User.IsInRole("SuperAdmin"))
{
string currentUserName = User.Identity.Name;
return GetHeaderSchoolName(currentUserName);
}
return string.Empty;
}
public string GetHeaderSchoolName(string userName)
{
Guid userId = SchoolBreifcase.Utilities.Common.GetUserId(userName);
SchoolBreifcase.Repositories.AdminRepository adminRepository = new SchoolBreifcase.Repositories.AdminRepository();
SchoolBreifcase.Models.Edmx.UserProfile userProfile = adminRepository.GetUserProfileByUserId(userId);
string CurrentSchoolName = userProfile.School.SchoolName;
return CurrentSchoolName + "xxx";
}
}
</div>
I have one button in inside of same razor view.And I called that method(schoolname()) in my below button onclick event (onclick="schoolname()") please see below
我在同一个剃刀视图内有一个按钮。我schoolname()在下面的按钮 onclick 事件 ( onclick="schoolname()") 中调用了该方法 ( )，请参见下文
<div class="logoHeader" style="float: right; width: 15%; padding-top: 5%;">
**<button onclick="schoolname()"> xx</button>**
</div>
But .Its Not working . My method is does not called .I have no idea for this task . You have Any idea here? and how to do solve this ?
但是。它不工作。我的方法没有被调用。我不知道这个任务。你有什么想法吗？以及如何解决这个问题？
Updated:
I know the procedure are threw controller ,action result,get ,post, java script,jquery,etc ,all . My question is What is use of @functions? in razor view . I know its helping to write server side code in inside of razor view . but i can't call this method in just one button click event . So what is the use it ? Its only used only for when page load .
我知道程序被抛出控制器、动作结果、获取、发布、java 脚本、jquery 等，所有。我的问题是有什么用@functions？在剃刀视图中。我知道它有助于在 razor view 中编写服务器端代码。但我不能只在一个按钮点击事件中调用这个方法。那有什么用呢？它仅用于页面加载时。

完成我的自我：
See below my Razor View Function :
请参阅下面我的 Razor 视图功能：
<div style="height: 50px; padding-left: 10%; width: 100%">
<b style="font-family: Arial, Helvetica, sans-serif; font-weight: normal; font-size: xx-large">
@functions {
public string schoolname()
{
if (Request.IsAuthenticated && !User.IsInRole("SuperAdmin"))
{
string currentUserName = User.Identity.Name;
return GetHeaderSchoolName(currentUserName);
}
return string.Empty;
}
public string GetHeaderSchoolName(string userName)
{
Guid userId = SchoolBreifcase.Utilities.Common.GetUserId(userName);
SchoolBreifcase.Repositories.AdminRepository adminRepository = new SchoolBreifcase.Repositories.AdminRepository();
SchoolBreifcase.Models.Edmx.UserProfile userProfile = adminRepository.GetUserProfileByUserId(userId);
string CurrentSchoolName = userProfile.School.SchoolName;
return CurrentSchoolName + "xxx";
}
}
</div>
And I am used javascript:window.location.href="schoolname"for call my function.Its working now .
我用于javascript:window.location.href="schoolname"调用我的函数。它现在可以工作了。
<div class="logoHeader" style="float: right; width: 15%; padding-top: 5%;">
**<button onclick='javascript:window.location.href="schoolname"'> xx</button>**
</div>
Thanks Guy's .
谢谢你们 。

You are doing it completely wrong my friend because Asp.net Mvc is not like classic Asp.net Web Forms. I suggest you take look at this bookfor more information. However to solve your problem you can easily do this in CShtml :
我的朋友，你完全错了，因为 Asp.net Mvc 不像经典的 Asp.net Web Forms。我建议你看看这本书以获取更多信息。但是要解决您的问题，您可以在 CShtml 中轻松执行此操作：
@{
var result = Request["YourButtonSpecialName"];
}
@if (result=="xx")
{
<div>
button clicked
</div>
}
<div class="logoHeader" style="float: right; width: 15%; padding-top:5%;">
<form action="YOUR CURRENT PATH">
<button type="submit" name="YourButtonSpecialName" value="xx"/>
</form>
</div>
