脚本未连接到JsonResult Controller [英] Script doesnt connect to JsonResult Controller
问题描述
我将具有自动完成功能的脚本连接到我的Json控制器时遇到问题.该视图是一个公式，用户可以在其中插入数据，例如带日期选择器功能的日期以及用于描述问题的通用文本.整个公式如下:
I have a problem with connecting the script with the autocomplete function to my Json controller. The view is a formula, where the user can insert data, like dates with the datepicker function and general text to describe the issues. The whole formula is in this:
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
@Html.ValidationSummary(true)
所有文本框，DropDownList和编辑器都按以下方式连接到模型:
All Textboxes, DropDownLists and Editors are connected to the model like so:
<div class="editor-label">
@Html.LabelFor(model => model.Overview)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Overview)
@Html.ValidationMessageFor(model => model.Overview)
</div>
此刻，我尝试插入文本框，其中自动填充应按以下方式进行:
At the moment I try to insert the Textbox, where the autocomplete should happen like this:
<b>Name: </b>
@Html.TextBox("searchTerm", null, new { id = "txtSearch" })
txtSearch已连接到我的skript SearchUser.js:
The txtSearch is connected to my skript SearchUser.js:
$(function () {
$("#txtSearch").autocomplete({
source: '@url.Action("New1", "Dialog")',
minLength: 1
});
});
当我使用源字符串数组时，会显示自动完成功能.
when I use a source an array of strings, the autocomplete appears.
JavaScript已注册在视图顶部，而jQueryUI已注册在_Layout.cshtml中.我正在使用jquery 1.11.3和jqueryui 1.11.4.
the JavaScript is registered on top of the view and jQueryUI is registered in _Layout.cshtml. I am using jquery 1.11.3 and jqueryui 1.11.4 .
在JsonResult的Controller New1中，您会找到以下内容:
In The Controller New1 in the JsonResult you find this:
public JsonResult Dialog(string search)
{
List<string> users = db
.Users
.Where(p => p.FirstName.ToLower().Contains(search.ToLower()))
.Select(p => p.LastName)
.ToList();
return Json(users, JsonRequestBehavior.AllowGet);
}
当我测试网站并查找 http://localhost:51299/New1/Dialog时? search = m
我得到了json文件. json文件包含以下内容:["Mueller"]
when i test the website and look for http://localhost:51299/New1/Dialog?search=m
i get the json file. The json file contains this: ["Mueller"]
但是当我转到公式 http://localhost:51299/New1/Create 并插入"m"进入TextBox不会发生任何事情.
But when I go to my formula http://localhost:51299/New1/Create and insert "m" into the TextBox nothing happens.
所以现在我的问题是:我该怎么做才能使其正常工作?
So now my question: What can i do to make it work?
Aaaaah它的工作！！！非常感谢！他无法使用源，所以现在我将其更改为"/New1/Dialog".
我知道这不是使用直接URL而不是'@ url.Action("Dialog"，"New1")'的好方法，但是我认为他在普通'和
Aaaaah its working!!!. Thanks a lot! He couldnt use the source, so now I changed it to "/New1/Dialog". I know it is not a good way to use the direct url instead of '@url.Action("Dialog", "New1")', but i think he couldnt differ between normal ' and ". If you have an Idea why i couldnt use @url.Action, i would be interested in it.
查看(Create.cshtml)
@Html.TextBox("searchTerm", null, new { id = "searchTerm" })
Skript(SearchUser.js)
$(function () {
$("#searchTerm").autocomplete({
source: "/New1/Dialog",
minLength: 1
});
});
控制器(New1Controller.cs)
public JsonResult Dialog(string term)
{
List<string> users = db
.Users
.Where(p => p.LastName.ToLower().Contains(term.ToLower()))
.Select(x => x.LastName)
.ToList();
return Json(users, JsonRequestBehavior.AllowGet);
}
推荐答案
jQueryUI自动完成功能使用名称term(而不是search)来编写请求.换句话说，当您输入"m"时，它将发送以下请求:
jQueryUI autocomplete is using the name term (not search) to craft a request. In other words, when you type "m", it's sending the following request:
您应该可以通过简单地重命名参数来解决此问题:
You should be able to fix this by simply renaming the parameter:
public JsonResult Dialog(string term)
