如何在javascript中引发C＃事件或函数

Question

I have a function in my login page an it access is protect like other C# function by default.

protected void MyFunction()
{
    //do somthing
}

I want to raise it in JavaScript something like this

<script>
    $.rise(MyFunction)
</script>

Someone said should use

__doPostBack(control, arg);

Or

<a .... onclick="TriggerPostBack('control', 'arg')" .. />

Or.... but all of this is for an ASP.NET object and if you use ASP.NET object it automatically generate callback and __doPostBack and everything you need.

Unfortunately I dont have an ASP.NET object and I use a simple HTML tag and want to raise ac# function by JavaScript manually. is it possible? and the access of function what should be? and about the security? is it logical or illogical?

At the end I want to postback happen because I am familiar with jQuery AJAX and in this case I dont need it. I want postback happen.

Change your method to a static webmethod and try an jquery ajax post.

$.ajax({
    type: "POST",
    url: "YourPage.aspx/MyFunction",
    data: '',
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: OnSuccess,
    failure: function(response) {
        alert(response.d);
    }
});

[WebMethod]
public static void MyFunction() 
{

}
