生成在JavaScript中的操作URL的ASP.NET MVC [英] Generating an action URL in JavaScript for ASP.NET MVC

问题描述

我想通过调用控制器特定参数的操作重定向到另一个页面。我试图用这个行：

I'm trying to redirect to another page by calling an action in controller with a specific parameter. I'm trying to use this line:

window.open('<%= Url.Action("Report", "Survey",
    new { id = ' + selectedRow + ' } ) %>');

但我无法使它工作;它提供了以下错误：

But I couldn't make it work; it gives the following error:

CS1012：字符字符太多文字

我能不能产生作用的URL，这是在客户端？还是我通过提供的参数进行Ajax调用并取回所需的网址是什么？这似乎并不正确，但我想，如果它是唯一的方法。

Can't I generate the action URL this was on the client side? Or do I have to make an Ajax call by supplying the parameter and get back the needed URL? This doesn't seem right, but I want to if it's the only way.

有没有更简单的解决方案？

Is there an easier solution?

推荐答案

记住之间＆LT一切;％和％>是PTED为C＃code间$ P $，所以你实际上做的是试图评价C＃以下行：

Remember that everything between <% and %> is interpreted as C# code, so what you're actually doing is trying to evaluate the following line of C#:

Url.Action("Report", "Survey", new { id = ' + selectedRow + ' } )

C＃认为单引号周围字符文字，因此，该错误信息你得到（字符文字只能包含在C＃中的单个字符）

C# thinks the single-quotes are surrounding a character literal, hence the error message you're getting (character literals can only contain a single character in C#)

也许你曾经可以在页面脚本生成URL - 在你的页面头部的地方，这样做：

Perhaps you could generate the URL once in your page script - somewhere in your page HEAD, do this:

var actionUrl =
    '<%= Url.Action("Report", "Survey", new { id = "PLACEHOLDER" } ) %>';

这会给你包含你所需要的URL一个JavaScript字符串，而是用占位符，而不是数量。然后设置你的点击处理程序为：

That'll give you a Javascript string containing the URL you need, but with PLACEHOLDER instead of the number. Then set up your click handlers as:

window.open(actionUrl.replace('PLACEHOLDER', selectedRow));

即。处理程序运行时，你会发现在你的pre-计算URL占位符值，并与选定行更换。

i.e. when the handler runs, you find the PLACEHOLDER value in your pre-calculated URL, and replace it with the selected row.
