[英]Passing a parameter to Action method
I have an action method like this我有这样的动作方法
public JsonResult Create(Product p, string extra)
The view is bound to @model Product
视图绑定到
@model Product
On calling Create action via ajax call, I am getting Product P values from the form but extra is always null, although extra is in the same form在通过 ajax 调用调用创建操作时,我从表单中获取产品 P 值,但额外的始终是 null,尽管额外的形式相同
<input type="text" name="extra" />
I also tried Request.Form["extra"] it was null too.我也试过 Request.Form["extra"] 它也是 null 。 What I am missing?
我错过了什么? how to get value of input[name=extra] in action method?
如何在操作方法中获取 input[name=extra] 的值?
You didn't mention how are you calling this action (other than saying AJAX which obviously is not enough), so assuming you have an HTML form representing a product and an input field containing some extra value:你没有提到你是如何调用这个动作的(除了说 AJAX 这显然是不够的),所以假设你有一个代表产品的 HTML 表单和一个包含一些额外值的输入字段:
@model Product
@using (Html.BeginForm())
{
@Html.EditorForModel()
<input type="text" name="extra" value="some extra value" />
<input type="submit" value="Create" />
}
you could unobtrusively AJAXify this form like this:你可以像这样悄悄地 AJAXify 这个表单:
$('form').submit(function() {
$.ajax({
url: this.action,
type: this.method,
data: $(this).serialize(),
success: function(result) {
// TODO: handle the results of the AJAX call
}
});
return false;
});
