我的视图具有带有单个隐藏提交按钮的表单。我想在加载页面时提交表格。但是,我在JavaScript中所做的任何提交都会给我这个错误:
无法获得未定义或null参考的财产'提交
这是我的代码:
printApplication.cshtml
@using (Html.BeginForm("PrintApplications", "Admin", FormMethod.Post, new { @id = "PrintApplications", @class = "form-horizontal ", @commandname = "ModelContract", @target = "_blank" }))
{
<input id="btnPrintApplications" type="submit" class="btn btn-primary" value="PrintApplications" name="submit" style="visibility: hidden" />
}
<script>
document.onreadystatechange = function () {
document.form.submit();
}
</script>
代替document.form.submit,我也尝试了
var form = document.getElementById("PrintApplications");
form.submit();
document.forms["PrintApplications"].submit();
this.form.submit();
和其他变体(例如,在表单名称的前面#)
我的代码有什么问题。还有其他方法可以自动提交页面(没有用户单击任何按钮)?
编辑:这是我的原始代码。它在IE中无效,这就是引发我遇到的问题的原因。没有错误,但表格没有提交。
在Chrome中效果很好。 $(document).ready(function () {
$("#btnPrintApplications").click();
});
编辑2:这是我从@barry
的帖子中使用代码工作的代码@using (Html.BeginForm("PrintApplications", "Admin", FormMethod.Post, new { @id = "PrintApplications", @class = "form-horizontal ", @commandname = "ModelContract", @target = "_blank" }))
{
@*<input id="btnPrintApplications" type="submit" class="btn btn-primary" value="PrintApplications" name="submit" style="visibility: hidden" />*@
<div>
If applications do not appear in a separate tab or window, please click the button below.
</div>
<input id="btnPrintApplications" type="submit" class="btn btn-primary" value="Print Applications" name="print" />
}
<script>
mySubmitButton = document.getElementById("btnPrintApplications");
mySubmitButton.click();
</script>
编辑3:这是使用 @chris-pratt的示例的代码。
@using (Html.BeginForm("PrintApplications", "Admin", FormMethod.Post, new { @id = "PrintApplications", @class = "form-horizontal ", @commandname = "ModelContract", @target = "_blank" }))
{
<div>
If applications do not appear in a separate tab or window, please click the button below.
</div>
<input id="btnPrintApplications" type="submit" class="btn btn-primary" value="Print Applications" name="print" />
}
<script>
window.onload = function () {
document.forms['PrintApplications'].submit();
}
</script>
以下简单的HTML文档完全按照您的要求函数:
<html>
<body>
<form id="Test" action="http://google.com" target="_blank">
<input type="hidden" name="q" value="test" />
</form>
<script>
window.onload = function () {
document.forms['Test'].submit();
}
</script>
</body>
</html>
我最初使用的document.onreadystatechange
,它也起作用,但注意到11显然是两次射击该事件,导致了两个弹出窗口。不管。也许通过向后工作,您可以找到自己的问题。
尝试theway
mySubmitButton = document.getElementById("PerfSubmit");
mySubmitButton.click();
使用以下代码,表格将提交
$('form')[0].submit();
或
mySubmitButton.trigger("click");
