提交后BeginFormSitefinity表单消失 [英] BeginFormSitefinity form disappears after submitting
问题描述
当我使用BeginFormSitefinity助手时，表单在提交后消失，然后回发完成.
When I use the BeginFormSitefinity helper the form disappears after submitting, and then the postback is done.
预期的行为只是要做的回发.我去浏览器进行调查，发现当您使用BeginFormSitefinity时，会在HTML中添加一个额外的脚本.
The expected behavior would be only the postback to be done. I went to the browser and investigated and I found out that when you use BeginFormSitefinity an extra script is added to your html.
该脚本基本上创建了一个新的带有display = none的表单.并将您的表单附加到不可见"表单上，因此您的表单在提交后就会消失.
That script basically creates a new form with display = none. And appends your form to the "invisible" form, and thus your form disappears after submitting.
我正在使用Sitefinity 8.1，我想知道是否有任何方法可以避免这种情况?
I'm using Sitefinity 8.1, and I would like to know if is there any way to avoid this?
这是添加的脚本(我无法控制):
This is the script added (I have no control over it):
<script type="text/javascript">
(function () {
var container = document.getElementById("myForm2");
if (container === null)
return;
var inputs = container.querySelectorAll("input");
var allInputs = document.forms["aspnetForm"].querySelectorAll('input');
for (var i = 0; i < allInputs.length; i++) {
allInputs[i].addEventListener("invalid", function(event) {
if (Array.indexOf(inputs, document.activeElement) >= 0 && Array.indexOf(inputs, event.target) < 0)
event.preventDefault();
}, true);
}
var submitClick = function () {
var isValid = true;
for (var i = 0; i < inputs.length; i++) {
if (typeof inputs[i].willValidate !== "undefined" && inputs[i].willValidate)
isValid = inputs[i].validity.valid && isValid;
if (typeof jQuery !== "undefined" && typeof jQuery.validator !== "undefined")
isValid = jQuery(inputs[i]).valid() && isValid;
}
if (isValid) {
var form = document.createElement("form");
form.style.display = "none";
form.setAttribute("action", "/order-calendar/Search");
form.setAttribute("method", "POST");
form.setAttribute("enctype", document.forms["aspnetForm"].getAttribute("enctype"));
form.setAttribute("encoding", document.forms["aspnetForm"].getAttribute("encoding"));
form.appendChild(container);
document.body.appendChild(form);
// We prevent kendo upload widget from submitting empty inputs.
var kInputs = container.querySelectorAll(".k-upload input[type='file']");
for(var i = 0; i < kInputs.length; i++) {
var kInput = kInputs[i];
if (!kInput.value) {
// Prevent submitting an empty input
kInput.setAttribute("disabled", "disabled");
window.setTimeout(function() {
kInput.removeAttribute("disabled");
}, 0);
}
}
form.submit();
return false;
}
};
var handleFormSubmitElements = function (elementName) {
var allSubmitElements = container.getElementsByTagName(elementName);
var elementCount = allSubmitElements.length;
while(elementCount) {
typeAttr = allSubmitElements[elementCount - 1].getAttribute("type");
if(typeAttr == "submit") {
allSubmitElements[elementCount - 1].onclick = submitClick;
}
elementCount--;
}
};
handleFormSubmitElements("input");
handleFormSubmitElements("button");
})();
</script>
这是我的表格(它的值是自动读取的，这就是onkeydown返回false的原因):
This is my form (its values are read automatically, that's why onkeydown returns false):
@using (Html.BeginFormSitefinity("Search", "myForm2"))
{
<div id="main_content" style="max-width: 600px; max-height:700px;float:left;overflow: hidden;">
<table>
<tr><td colspan="2" style="text-align:center;">@Html.Label("City")</td></tr>
<tr>
<td>@Html.Label("Code") </td>
<td>
@Html.Kendo().TextBoxFor(x => x.Code).HtmlAttributes(new { onkeydown = "return false", style = "color: green; width:100%;", id = "Code" })
</td>
</tr>
<tr>
<td>@Html.Label("City Code") </td>
<td>
@Html.Kendo().TextBoxFor(x => x.CityCode).HtmlAttributes(new { onkeydown = "return false", style = "color: green; width:100%;", id = "CityCode" })
</td>
</tr>
</table>
<input type="submit" class="btn btn-success" value="submit">
}

我们的团队也遇到了同样的问题.已创建到Telerik的支持票.有一个答案:
Our team also had the same issue. Was created support ticket to Telerik. And there is an answer:
本质上，这是使用BeginFormSitefinity时的预期行为.发生这种情况的原因是，在ASP.NET Web表单中，页面上仅允许使用一种带有runat ="sever"的表单.这就是为什么BeginFormSitefinity在默认情况下呈现为div并单击提交按钮时动态创建并提交表单的原因.为了克服此行为，您将需要创建一个自定义帮助程序和HybridForm.您可以查看以下 StackOverflow答案，以获取有关如何创建自定义HybridForm的更多信息.
Essentially, this is expected behavior when using the BeginFormSitefinity. The reasons this happens is because in ASP.NET web forms only one form with runat="sever" is allowed on a page. This is why the BeginFormSitefinity renders as a div by default and a form is dynamically created and submitted when the submit button is clicked. In order to overcome this behavior you will need to create a custom helper and HybridForm. You can take a look at the following StackOverflow answer for more information on how to create a custom HybridForm.
