Confirmation for Url.Action in razor
提问by TBA
Hi I am using an edit button inside a gridview. I want a confirmation button before calling to the action?
嗨，我在 gridview 中使用编辑按钮。在调用操作之前我需要一个确认按钮吗？
grid.Column("","",format:@<text>@if(!item.IsBookPublished)
{
<text> <a href='@Url.Action("EditBookByID","Books", new {BookID = @item.BookDetailsID, CreatedBy = @item.UserID , onclick = "return confirm('Are you sure you want to Edit?')" })'>Edit</a></text>
}
</text>
However the onclick property is not evaluating, instead it is passing as a parameter. How can I achieve confirmation?
但是 onclick 属性没有评估，而是作为参数传递。我怎样才能获得确认？

You've placed it at the wrong place. Right now you've passed it as parameter to the Url.Action helper, whereas it should be a separate attribute, the same way you defined the href attribute:
你把它放在错误的地方。现在您已经将它作为参数传递给 Url.Action 助手，而它应该是一个单独的属性，与您定义 href 属性的方式相同：
<a href="@Url.Action("EditBookByID", "Books", new { bookID = item.BookDetailsID, CreatedBy = item.UserID })" onclick="return confirm('Are you sure you want to Edit?')">Edit</a>
By the way you should consider using helpers for that:
顺便说一句，您应该考虑为此使用助手：
grid.Column("", "", format:
@<text>
@if(!item.IsBookPublished)
{
Html.ActionLink(
"Edit",
"EditBookByID",
"Books",
new { bookID = @item.BookDetailsID },
new { onclick = "return confirm('Are you sure you want to Edit?')" }
)
}
</text>
)

By putting the 'onclick' inside the Url.Action helper, you're tellingit to translate it as a URL parameter.
通过将 'onclick' 放在 Url.Action 助手中，您是在告诉它把它翻译成一个 URL 参数。
What you want to do instead is put the onclick outside the helper like this:
您想要做的是将 onclick 放在助手之外，如下所示：
<a href='@Url.Action("EditBookByID","Books", new {BookID = @item.BookDetailsID, CreatedBy = @item.UserID })' onclick = "return confirm('Are you sure you want to Edit?')">
Edit
<a>
