javascript - razor 中 Url.Action 的确认

Question

嗨，我正在使用 gridview 中的编辑按钮。在调用操作之前我想要一个确认按钮？

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>

但是 onclick 属性没有评估，而是作为参数传递。我怎样才能实现确认？

Answer 1

你放错地方了。现在您已将它作为参数传递给 Url.Action 帮助程序，而它应该是一个单独的属性，与定义 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>

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>
)

Answer 2

通过将“onclick”放在 Url.Action 帮助器中，您是在告诉它将其转换为 URL 参数。

您想要做的是将 onclick 放在帮助器之外，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>
