[英]How to open a new tab after server's Post Action Result
這是情況。
我有一個保存和一個打印按鈕:
<input name="btnSubmit" type="submit" value="Save" />
<input name="btnSubmit" type="submit" value="Print"/> @*Redirect to Action("Print", "controler")*@
但是打印按鈕必須打開一個新選項卡 。 如果僅僅是我,我顯然知道我必須在打印之前保存……這不是問題。 我可以將此鏈接與目標空白結合使用:
<a target="_blank" href="@Url.Action("Print", "controler", new { id = Model.id })" type="submit" value="Print" > Print</a>
很簡單,但是現在有些用戶認為打印按鈕也應該保存頁面。 因為他們不推送保存...他們只是打印而模型更改丟失了,因為我無法在我的打印鏈接中調用post操作...這是一個鏈接。
我以為,起初我可以對保存功能進行異步調用,但是我的模型太大了,它需要回傳自己的動作(對嗎?)
通過這個:
如何在response.redirect上使用Target = _blank?
而且我不確定它是否真的對MVC有幫助...現在我被困在這里:
[HttpPost]
public ActionResult MyForm(string btnSubmit, formModel model)
{
if (btnSubmit == "Print")
{
dbSave(model);
return RedirectToAction("Print", "controler"); // Won't open new tab...
}
}
首先,當用戶單擊打印按鈕時,我通過ajax請求發布我的數據,成功完成后,我打開一個新標簽。
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();
});
要么
您想在http響應中編寫類似示例的內容,然后可以執行類似操作
HttpContext.Current.Response.Write( @"<script type='text/javascript' language='javascript'>window.open('page.html','_blank').focus();</script>");
UPDATE
我在下面添加了一個完整的測試項目流程。
例:
模型:
public class Product
{
public int Id { get; set; }
public string Name { get; set; }
public string ProductCode { get; set; }
public decimal Price { get; set; }
}
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);
}
public ActionResult Print()
{
return View();
}
}
Save.cshtml:
@model Product
@{
ViewBag.Title = "Save";
}
<h2>Save</h2>
@Html.Hidden("saveButton","Test")@*Change Test to your value or change it to using JavaScript*@
@using (Html.BeginForm("Save", "Product", new {area = ""}, FormMethod.Post, new {id = "fileForm", name = "fileForm"}))
{
@Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>Product</h4>
<hr />
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
<div class="form-group">
@Html.LabelFor(model => model.Name, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Name, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.Name, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(model => model.ProductCode, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.ProductCode, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.ProductCode, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(model => model.Price, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Price, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.Price, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<button type="button" class="btn btn-primary" id="btnSave">Save</button>
<button type="button" class="btn btn-default">Print</button>
</div>
</div>
</div>
}
腳本:
<script>
$("#btnSave").click(function() {
$.ajax({
url: $("#fileForm").attr('action'),
type: $("#fileForm").attr('method'),
beforeSend: function() {
},
data: $("#fileForm").serialize() + "&saveButton=" + $("#saveButton").val()
}).done(function(result) {
if (result.OpenUrl) {
window.open(result.OpenUrl, '_blank');
}
if (result.redirectTo) {
setTimeout(function() {
window.location.href = result.redirectTo;
},2000);
}
});
})
</script>
