Make an AJAX request using $.ajax in MVC 4
提问by Mason
I am trying to make an AJAX request using $.ajax in MVC 4 with Razor. I'm not sure how to implement it.
我正在尝试在带有 Razor 的 MVC 4 中使用 $.ajax 发出 AJAX 请求。我不确定如何实现它。
Using this videoI was able to successfully make a link-driven call that returned data, but I can't seem to do the same thing from inside a jquery function. I can't seem to find any basic examples of how to do this. This is what I am working with:
使用此视频，我能够成功进行返回数据的链接驱动调用，但我似乎无法从 jquery 函数内部执行相同的操作。我似乎无法找到有关如何执行此操作的任何基本示例。这就是我正在使用的：
HomeController.cs
家庭控制器.cs
public string test(){
return "It works";
}
View.cshtml
查看.cshtml
function inventory(dealerID) {
$.ajax({
url: '@Url.Action("HomeController","test")',
data: {dealerID: dealerID},
type: 'POST',
success: function(data) {
process(data);
}
});
}

You just need to make it an ActionResult. Also, if you're using an Ajax POST, then the action needs to be marked with the HttpPostattribute. Try this:
你只需要把它变成一个ActionResult. 此外，如果您使用 Ajax POST，则需要使用HttpPost属性标记操作。尝试这个：
[HttpPost]
public ActionResult test(string dealerID)
{
return Content("It works");
}
EditActually, there are a few other problems with the syntax.
编辑实际上，语法还有其他一些问题。
Url.Actionhas the controller/action parameters in the wrong order -- should be "ActionName" first, then "ControllerName"- For
Url.Action, if the controller class is "HomeController", then you need just "Home" - The JQuery options syntax is wrong -- should be
success: function(data) {}.
Url.Action控制器/动作参数的顺序错误——应该先是“ActionName”，然后是“ControllerName”- 对于
Url.Action，如果控制器类是“HomeController”，那么您只需要“Home” - JQuery 选项语法错误 - 应该是
success: function(data) {}.
$.ajax({
url: '@Url.Action("test", "Home")',
data: {dealerID: dealerID},
type: 'POST',
success: function(data) {
alert(data);
}
});
