我的问题背后的概念是，每当我的ID文本框中显示一个值时，该值id通过AJAX和Javascript将部分视图中对应于该ID的信息拉到页面右侧。
我目前正在右侧显示局部视图，但铬有一个错误警告，它无法填充局部视图，所以它只显示空的局部视图（文本框等）。我已经尝试过研究我的问题，但是找不到与html.partial（）有关的任何内容，而是在页面中已有我不想要的视图教程。关于我哪里出错的任何想法？下面是关于这个问题的代码。
我仍在掌握AJAX，因此对任何愚蠢的错误道歉。

我认为问题将是你在ajax中的url - 实际上我知道，因为错误消息也说明了它：
无法找到资源 请求的URL：/QR/@Url.Action("Edit“，”CameraInfo“）。
原因是该文件无法识别Razor语法。
从局部视图中设置js变量，如：
<!-- In the end of your partial view, or wherever you referense the js-file -->
<script type="text/javascript">
var myJsUrl = '@Url.Action("Edit", "CameraInfo")';
</script>
//In your JS-file, assuming this is referensed from your partial view
$.ajax({
type: "Get",
url: myJsUrl,
...
或者只需手动输入（最简单的解决方案）：
$.ajax({
type: "Get",
url: '/CameraInfo/Edit',
...
我还应该说，在每个方法/调用之前不需要继续编写$(document).ready。只需执行一次，并将所有代码放在该范围内。
编辑：
此外，您将两个更改事件绑定到同一个文本框（#qr-value）。合并代码并仅保留一个事件：
$(document).ready(function () {
$('#qr-value').on('change', function () {
var string = $('#qr-value').val();
if (~string.indexOf('Job')) {
var num = string.match(/\d+/g);
$("#qr-number").val(num).change();
$("#second").show(1000);
} else {
$("#qr-number").val("")
$("#second").hide(500);
}
$.ajax({
type: "Get",
url: '/CameraInfo/Edit',
data: { id: $('#qr-number').val() },
success: function (response) {
$('#Sample').html(response);
},
error: function (response) {
if (response.responseText != "") {
alert(response.responseText);
alert("Some thing wrong..");
}
}
});
});
});

似乎你的camerainfo文件需要＆＃34; Job＆＃34;模型。如果要渲染部分并使用控制器启动模型，可以使用
@{Html.RenderAction("actionName","controllerName")}
