Ajax Not returning Data to Action ASP.net MVC
I am new to MVC and facing a problem with accessing data via ajax in action of my ASP.NET Application. Here is my Ajax Code:
$('.testBtn').click(function() {
$.ajax({
type: 'GET',
data: { id: 10 },
url="@Url.Action("GetData", "Consultation")",
success:function()
{
}
});
});
And here is my action inside the controller:
public ActionResult GetData(int id)
{
string x=id.ToStrring();
return null;
}
For testing I am just passing a static integer and getting its value inside my action.
On clicking the button I am getting the following error:
The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult GetData(Int32)' in 'careshade_mvc.Controllers.ConsultationController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.
这是工作代码：
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-2.0.3.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('.testBtn').click(function () {
$.ajax(
{
url: 'Consultation/GetData',
type: "POST",
data: { id: 10 },
success: function (result) {
}
});
});
});
</script>
</head>
<body>
<input type="button" class="testBtn" value="ClickHere" name="button">
</body>
</html>
尝试这个：
$(document).ready(function() {
var id = 10;
$('.testBtn').click(function () {
$.ajax(
{
url: 'Consultation/GetData/' + id,//instead data: { id: 10 },
type: "GET",
success: function (result) {
}
});
});
});
You need to use a colon(:) character after url not the equals(=) sign.
Simply change:
url="@Url.Action("GetData", "Consultation")",
To this:
url:"@Url.Action("GetData", "Consultation")",
This was the only change I had to make to make the call work.Hope it helps you!
