Question

情况就是这样。

我有一个保存和一个打印按钮：

<input name="btnSubmit" type="submit" value="Save" /> 
<input name="btnSubmit" type="submit" value="Print"/> @*Redirect to Action("Print", "controler")*@

但是打印按钮必须打开新标签页。如果只是我，我显然知道我必须在打印前保存...这不是问题。我可以使用此链接与目标空白：

<a target="_blank" href="@Url.Action("Print", "controler", new { id = Model.id })" type="submit" value="Print" > Print</a>

很简单，但现在有些用户认为打印按钮也应该保存页面。因为他们没有推送保存......他们只是打印并且模型更改丢失了，因为我无法在我的打印链接中调用post动作...这是一个链接。

我一开始认为，我可以对保存功能进行异步调用，但我的模型太大了，需要回传自己的动作（对吗？）

经历过这个：

How do I use Target=_blank on a response.redirect?

我不确定它是否真的对MVC有帮助......现在我被困在这里：

[HttpPost]
public ActionResult MyForm(string btnSubmit, formModel model)
{
    if (btnSubmit == "Print")
    {
        dbSave(model);
        return RedirectToAction("Print", "controler"); // Won't open new tab... 
    }
}

Answer 1

当用户点击打印按钮时，我首先按照ajax请求发布我的数据，并在成功完成后打开一个新标签。

示例：

$.ajax({
    url: "@Url.Action("create", "Post")",
    type: "POST",
    contentType: "application/json",
    data: JSON.stringify({ model: model})
}).done(function(result){
window.open('@Url.Action("Print", "controler", new { id = Model.id })', '_blank').focus();
});

OR

你想在http响应中编写类似你的例子的东西，然后你可以做类似

的事情

  HttpContext.Current.Response.Write( @"<script type='text/javascript' language='javascript'>window.open('page.html','_blank').focus();</script>");

我在下面添加了完整的测试项目流程。

public class Product
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string ProductCode { get; set; }
    public decimal Price { get; set; }
}

<强>控制器：

 public class ProductController : Controller
    {
        // GET: Product
        public ActionResult Index()
        {
            return View();
        }


        // GET: Product/Create
        public ActionResult Save()
        {
            var model = new Product();
            return View(model);
        }

        // POST: Product/Create
        [HttpPost]
        public ActionResult Save(Product model, string saveButton)
        {
            if (ModelState.IsValid)
            {
                //do something 
                return
                    Json(
                        new
                        {
                            redirectTo = Url.Action("Index", "Product", new { Area = "" }),
                            OpenUrl = Url.Action("Print", "Product", new { Area = "" })

                        });
            }
            return View(model);
