MVCToolKit中HtmlHelper.ActionLink的BUG?

發(fā)布時(shí)間:2023/12/10 c/c++ 37 豆豆
生活随笔 收集整理的這篇文章主要介紹了 MVCToolKit中HtmlHelper.ActionLink的BUG? 小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
分頁時(shí)

????<%?if?(ViewData.Accounts.IsPreviousPage)?{?%>
????????
<%=Html.ActionLink<SpeakOutFreely.Controllers.ManageController>(c?=>?c.List(ViewData.Accounts.PageIndex?-?1),?"Previous")%>
????
<%?}?%>

????
<%?if?(ViewData.Accounts.IsNextPage)?{?%>
????????
<%=Html.ActionLink<SpeakOutFreely.Controllers.ManageController>(c?=>?c.List(ViewData.Accounts.PageIndex?+?1),?"Next")%>
????
<%?}?%>????第一次點(diǎn)下一頁(Next)生成的HTML
http://localhost:64701/Manage/List/1
再點(diǎn)一次下一頁(Next)
生成的URL
http://localhost:64701/Manage/List/1/2
應(yīng)當(dāng)是
http://localhost:64701/Manage/List/2 才對!
汗,直接The resource cannot be found. 了...

搜了下。

Bug 1
If I create a controller action as follows...public void List(int category)... and use the MVCToolkit HtmlHelper.ActionLink<T> as follows...<%= Html.ActionLink<ProductController>( x => x.List(Category), "View Products for this category" ) %>... it generates the URL
http://server/Product/List/1 instead of http://server/Product/List/?category=1 and when i browse to the URL it says "A value is required for parameter 'category' in action 'List'"[this is due to LinkExtensions.BuildQueryStringFromBLOCKED EXPRESSION always assuming the first parameter should be simply appended to the url]
?Bug 2 If I create a controller action as follows...public void View(int Id)... and use the MVCToolkit HtmlHelper.ActionLink<T> as follows...<%= Html.ActionLink<ProductController>( x => x.View(ProductId), "View Product" ) %>... it correctly generates the URL
http://server/Product/View/1. However, when you navigate to that URL the same link now becomes http://server/Product/View/1/1. [this is because, in LinkExtensions.BuildUrl(), the call to UrlHelper.Action() parses the current URL and includes any current values (like Id) if it's a call to the same action. So maybe this is a bug with the way UrlHelper.Action works?? ]

只能這樣寫了..郁悶...
?<a?href="/Manage/List/<%=?ViewData.Accounts.PageIndex-1?%>"">上一頁</a>
??
<a?href="/Manage/List/<%=?ViewData.Accounts.PageIndex+1?%>"">下一頁</a>
