我有一个MVC应用程序,它将列出名称。名称位于实体框架数据库中。计时器位于列表中的第一个名称旁边,当计时器结束时,名称将从列表中删除,计时器将再次开始下一个记录(这将一直持续到没有名字留下)。
我还可以在列表中添加名称。现在,当用户通过单击创建链接向列表添加名称时,会添加名称,但会重新启动正在倒计时的当前计时器。我需要添加名称而不刷新计时器。那可能吗?
查看:
@model IEnumerable<RangeTimer.Models.UserName>
@{
ViewBag.Title = "ABC";
}
<div class="jumbotron">
<p>
@Html.ActionLink("Add Name to list for range time", "Create")
</p>
<table class="table">
<tr>
<th>
@Html.DisplayNameFor(model => model.FullName)
</th>
<th>
Time Remaining
</th>
<th></th>
</tr>
@foreach (var item in Model)
{
<tr>
<td id="FullName">
@Html.DisplayFor(modelItem => item.FullName)
</td>
<td>
<span id="timer"></span>
</td>
</tr>
}
</table>
</div>
<br/>
<script language="javascript" type="text/javascript">
$(document).ready(function () {
startTimer();
function startTimer() {
$('#timer').countdown({
layout: '{mnn} : {snn}', timeSeparator: ':', until: 15, onTick: TimerColorChange, onExpiry: restartTimer
});
}
function restartTimer() {
$('#timer').countdown('destroy');
var currentName = $('#FullName').Text;
//we delete the table's Info
var deleteRecord = $('#FullName').parent().remove();
// deleteRecord.deleteRow(); //commented out since this also removes my timer
var action = '@Url.Action("DeleteName","Controller")';
$.get(action + "?name=" + currentName).done
(function (result) {
if (result) {
// your user is deleted
}
})
startTimer();
}
function TimerColorChange(periods) {
var seconds = $.countdown.periodsToSeconds(periods);
if (seconds <= 3) {
$(this).css("color", "red");
} else {
$(this).css("color", "black");
}
}
});
</script>

如果您要向addname操作发送时间参数,则必须添加重定向参数。而不是使用viewbag.time。

是的,这是可能的!通过Ajax和Javascript / jQuery的魔力,您可以在通过ajax添加名称时调用您的控制器以提交名称并返回添加的名称并使用Javascript或jQuery将其附加到页面。不幸的是,这有点复杂,我暂时无法为你写出来。但是,请尝试其中一些链接。

Making a Simple Ajax call to controller in asp.net mvc
祝你好运!编辑: 这是使用jQuery / ajax
的javascript函数的一小部分示例function AddName(name) {
$.ajax({
url: action, // Make it whatever your controller is
data: { UserName: name }, // or whatever object you need
type: "POST",
dataType: "html",
success: function (result, status, blah) {
if (result) {
AppendRow(result, target); // Create function to add to your name list
}
},
error: function (result) {
AjaxFailed(result, result.status, result.error);
}
});
}
