AspNetCore Mvc 使用 PartialView
控制器：
public IActionResult queryMongoDb(string dbname)
{
List<MongoDbModel> mdList = new List<MongoDbModel>();
if (!string.IsNullOrWhiteSpace(dbname))
{
List<BsonDocument> document = mongo.FindFilterlData(new BsonDocument() {
{"title",dbname}
});
for (int i = 0; i < document.Count; i++)
{
MongoDbModel md = new MongoDbModel()
{
id = i + 1,
title = document[i]["title"].ToString(),
url = document[i]["title"].ToString(),
likes = document[i]["likes"].ToDouble(),
tags = mongo.getStrListByBson(document[i]["tags"])
};
mdList.Add(md);
}
}
return PartialView("MongoDbPartial", mdList);
}
最好在Shared中创建局部视图，这样减少了耦合度：
@model IEnumerable<MongoDbDemo.Models.MongoDbModel>
<table class="table">
<thead>
<tr>
<th>
@Html.DisplayNameFor(model => model.id)
</th>
<th>
@Html.DisplayNameFor(model => model.title)
</th>
<th>
@Html.DisplayNameFor(model => model.url)
</th>
<th>
@Html.DisplayNameFor(model => model.tags)
</th>
<th>
@Html.DisplayNameFor(model => model.likes)
</th>
<th></th>
</tr>
</thead>
<tbody>
@foreach (var item in Model)
{
<tr>
<td>
@Html.DisplayFor(modelItem => item.id)
</td>
<td>
@Html.DisplayFor(modelItem => item.title)
</td>
<td>
@Html.DisplayFor(modelItem => item.url)
</td>
<td>
@{
foreach (var tagsItems in item.tags)
{
<p>@tagsItems</p>
}
}
</td>
<td>
@Html.DisplayFor(modelItem => item.likes)
</td>
<td>
@Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) |
@Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) |
@Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
</td>
</tr>
}
</tbody>
</table>
主视图：
@model IEnumerable<MongoDbDemo.Models.MongoDbModel>
@{
Layout = null;
}
<script typet="text/javascript" src="http://libs.baidu.com/jquery/1.9.1/jquery.min.js"></script>
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
<form>
<p>
<a asp-action="Create">Create New</a>
<div>
名称：<input type="text" placeholder="条件1" id="selName"/>
<input type="button" value="查询" id="butn" />
</div>
<div id="datamain">
@Html.Partial("/Views/Shared/MongoDbPartial.cshtml", Model)
</div>
</p>
</form>
<script>
$(function () {
$("#butn").click(function () {
var nameval = $("#selName").val();
alert(nameval);
$.ajax({
url: "/MongoDB/queryMongoDb",
data: { dbname: nameval },
type: "get",
success: function (datas) {
console.log(datas);
$("#datamain").html(datas);
}
})
})
})
</script>
</body>
</html>
主要的思路是：
1.在主页面上定义个一div。
2.点击按钮（或者其他动作），触发div的load事件。
3.在前端js或者后台Action中避免页面缓存。
4.页面加载。
