[英]mvc call controller from jquery with parameter
I want to call MVC controller method from Jquery. 我想从Jquery调用MVC控制器方法。 Below is my code but it is not working
下面是我的代码,但它不起作用
Controller: 控制器:
public ActionResult singleValue(string valuetoset)
{
//Code
}
JQuery: JQuery的:
$('#User').live('change', function (e) {
var userValue = e.target.options[e.target.selectedIndex].value;
$.ajax({
url: "/Home/singleValue",
type: 'GET',
data: { valuetoset: userGuideValue },
success: function (result) {
alert(result);
},
error: function () {
alert("error");
}
});
});
I need to pass valuetoset argument, but it always going as null 我需要传递valuetoset参数,但它始终为null
您需要更改url ajax方法应如下所示:
url:'@Url.Action("Home", "singleValue")',
Your data
parameter needs to be in JSON format. 您的
data
参数必须为JSON格式。 There are a number of ways to do so, here's one: 有很多方法可以做到,这是一种:
var myData = {};
myData["valuetoset"] = userValue;
Here, valuetoset
corresponds to your controller action parameter. 在这里,
valuetoset
对应于您的控制器操作参数。 Then, your data
declaration should be as follows: 然后,您的
data
声明应如下所示:
data: myData
Or, you could just include userValue
in your URL if your routes are set up correctly since this is a GET action: 或者,如果路由设置正确,则只需在URL中包含
userValue
,因为这是GET操作:
url: host + "/Home/singleValue/" + userValue
