Question

我一直在寻找这个问题，并试图修复了几天，但没有成功。我在这段代码中做什么错？我要打印_Champions 和_SearchEngine中PartialView中的Home/Index为public class HomeController : Controller { public ActionResult Index() { return View(); } [HttpGet] public ActionResult _SearchEngine() { SearchLeagueModel searchLeagueModel = new SearchLeagueModel(); searchLeagueModel.MainSelector = "champions"; return PartialView("_SearchEngine", searchLeagueModel); } public ActionResult _SearchEngine(SearchLeagueModel searchLeagueModel) { if (searchLeagueModel.MainSelector == "champions") { return RedirectToAction("_Champions", searchLeagueModel); } else return View(); } [HttpPost] public ActionResult _Champions(SearchLeagueModel searchLeagueModel) { string chooser = searchLeagueModel.MainSelector; string selector; if (searchLeagueModel.MainSelector != null) { selector = "filter[name]=" + searchLeagueModel.MainSelector; } else { selector = ""; } WebRequest request = WebRequest.Create("https://api.pandascore.co/lol/" + chooser + "?" + selector + "&token=mytoken); WebResponse response = request.GetResponse(); Stream stream = response.GetResponseStream(); StreamReader reader = new StreamReader(stream); string responseFromServer = reader.ReadToEnd(); List<ChampionsModel> champions = JsonConvert.DeserializeObject<List<ChampionsModel>>(responseFromServer); return PartialView("_Champions", champions); } //other views }，但显示错误。

我的IndexModelView

我的_Champions.cshtml PartialView（作为PartialView制造）

@model LeagueAPI.Models.IndexModelView

@Html.Action("_SearchEngine", Model.Searcher)
@Html.Action("_Champions", Model.ChampionsList)

索引视图

_Layout

其他一切看起来都很标准，在@RenderBody()中，我有_Champions Controller 我的第二个问题是关于IndexModelView indexModelView = new IndexModelView()。为什么当我将ActionResult作为参数并对此MainSelector进行必要的代码更改时，在这种情况下setwd("~/Desktop") causes<-read.csv('causes.csv') head(causes) table(causes$Intentional.self.harm..suicide) barplot(table(causes$Intentional.self.harm..suicide)) barplot(table(causes$Intentional.self.harm..suicide), ylab='Frequency', main='Barplot of Intentional self-harm (suicide)', col='lightblue' dput(head(causes, 20)) Intentional.self.harm..suicide. = c(535L, 579L, 480L, 541L, 499L, 537L, 466L, 453L, 459L, 494L, 520L, 553L, 525L, 588L, 578L, 631L, 676L, 656L, 757L, 673L)为空。我仍在学习，如果您能在这里解释出什么问题我将很感激。欢呼

Answer 1

我会说不是ActionResults而是在Action _Champions和_SearchEngine上都使用PartialViewResult

[HttpPost]
public PartialViewResult _Champions(SearchLeagueModel searchLeagueModel)
{
       return PartialView("_Champions", champions);
}

然后从索引视图呈现这些操作如下所示：

@model LeagueAPI.Models.IndexModelView
<div>
@Html.RenderAction("_Champions");
@Html.RenderAction("_SearchEngine");
</div>

Answer 2

尝试以下Java脚本：-

<script>
function printContent(el){
    var restorepage = document.body.innerHTML;
    var printcontent = document.getElementById(el).innerHTML;
    document.body.innerHTML = printcontent;
    window.print();
    document.body.innerHTML = restorepage;
}
</script>
