ASP.NET MVC jQuery的自动完成与脚本url.action帮手包含在一个页面 [英] ASP.NET MVC jQuery autocomplete with url.action helper in a script included in a page
问题描述
我一直在建设我的第一个ASP.NET MVC的Web应用程序。我一直在使用jQuery自动完成构件在许多地方是这样的：
I have been building my first ASP.NET MVC web app. I have been using the jQuery autocomplete widget in a number of places like this:
<head>
$("#model").autocomplete({ source: '<%= Url.Action("Model", "AutoComplete") %>' });
</head>
问题是我在许多不同的地方这个jQuery code到我的web应用程序。所以我想我会创建一个单独的javascript脚本（的script.js）在那里我可以把这个code，然后只需将其包含在母版页。然后，我就可以把code，所有这些作品多次在剧本，只是给他们打电话，我需要太多。所以，我这样做。我的code如下所示：
在site.js剧本我把这个功能：
The thing is I have this jQuery code in a number of different places through my web app. So i thought I would create a seperate javascript script (script.js) where I could put this code and then just include it in the master page. Then i can put all these repeated pieces of code in that script and just call them where I need too. So I did this. My code is shown below:
In the site.js script I put this function:
function doAutoComplete() {
$("#model").autocomplete({ source: '<%= Url.Action("Model", "AutoComplete") %>' });
}
在网页上我有：
On the page I have:
<head>
<script src="../../Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script src="../../Scripts/site.js" type="text/javascript"></script>
<script type="text/javascript">
doAutoComplete();
</script>
</head>
但是当我这样做，我得到一个无效参数异常，自动完成不工作。我究竟做错了什么？任何想法？我需要的东西传递给doAutoComplete功能？
But when I do this I get an Invalid Argument exception and the autocomplete doesnt work. What am I doing wrong? Any ideas?Do i need to pass something to the doAutoComplete function?
推荐答案
在＆lt;％=不会在外部JavaScript进行评估
The <%= will not be evaluated in your external javascript.
解决方案：通过URL作为参数传递给你的javascript函数
Solution: pass the URL as a parameter to your javascript function.
<script>
doAutoComplete('<%= Url.Action("Model", "AutoComplete") %>');
</script>
function doAutoComplete(url) {
$("#model").autocomplete({ source: url });
}
