在一个MVC的局部视图文件中,我创建了一个Html.TextBox和两个提交按钮。这两个按钮在点击后会增加/减少Html.TextBox的值。Html.TextBox显示的值将相应地改变。但是,一旦我需要根据点击后的新值更新#refTable div,页面或部分就永远不会更新。下面是代码,其中添加了一些注释以解释。感谢您的帮助。
<body>

<input type="submit" value="PrevY" name="chgYr2" id="pY" />
@{
var tempItem3 = Model.First(); // just give the first entry from a database, works.
if (ViewData["curSel"] == null)
{
@Html.TextBox("yearSelect3", Convert.ToDateTime(tempItem3.Holiday_date).Year.ToString());
ViewBag.selYear = Convert.ToDateTime(tempItem3.Holiday_date).Year; // just initial value, works
ViewData["curSel"] = Convert.ToDateTime(tempItem3.Holiday_date).Year;
}
else
{
@Html.TextBox("yearSelect3", ViewData["curSel"].ToString());
}
}
<input type="submit" value="NextY" name="chgYr2" id="nY" />
<script type="text/javascript">
$(document).ready(function () {
$(document).on("click", "#nY", function () {
var val = $('#yearSelect3').val();
$('#yearSelect3').val((val * 1) + 1);
var dataToSend = {
id: ((val * 1) + 1)
}
// add some jquery or ajax codes to update the #refTable div
// also ViewBag.selYear need to be updated as ((val * 1) + 1)
// like: ViewBag.selYear = ((val * 1) + 1);
// any similar temp variable is fine
});
});
$(document).on("click", "#pY", function () {
var val = $('#yearSelect3').val();
$('#yearSelect3').val((val * 1) - 1);
var dataToSend = {
id: ((val * 1) - 1)
}
});
