在用户从 DropDownListFor 中选择某个值后,我尝试禁用 2 个 TextBoxFor 元素。我写了一个 javascript 函数,但不知何故它不起作用:这是代码:

@model MvcAcpplication.ViewModels.CalendarViewModel
@{
ViewBag.Title = "Calendar";
}

<h3 class="page-title">@ViewBag.Title</h3>
<link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" />
<link href="@Url.Content("~/assets/plugins/jquery-ui/jquery-ui-1.10.1.custom.min.css")"rel="stylesheet" type="text/css"/>


<ul class="breadcrumb">
<li>
<i class="icon-home"></i>
<a href="Index">@ViewBag.Title</a>

<i class="icon-angle-right"></i>
</li>
<li>
<a href="#">Create new calendar entry</a>
</ul>
<script src="@Url.Content("~/assets/plugins/jquery-1.10.1.min.js")"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>


@using (Html.BeginForm())
{ @Html.ValidationSummary(true)
<div class="form-horizontal form-view">

<h3>@ViewBag.Title </h3>
<h3 class="form-section">General</h3>
<div class="row-fluid">
<div class="span6 ">
<div class="control-group">
<label class="control-label">*Title:</label>
<div class="controls">
<span class="text">@Html.EditorFor(model => model.title)
@Html.ValidationMessageFor(model => model.title)
</span>
</div>
</div>
</div>
<!--/span-->
</div>

<div class="row-fluid">

<div class="control-group">

@Html.ValidationMessageFor(model => model.start)

</div>
</div>
</div>
</div>

<div class="row-fluid">
<div class="span6 ">
<div class="control-group">
<label class="control-label">*End:</label>
<div class="controls">
@(new HtmlString(@Html.TextBoxFor(model => model.end, new { id = "datepicker_end" }).ToString()))
@Html.ValidationMessageFor(model => model.end)

</div>
</div>
</div>
</div>


<div class="row-fluid">

<div class="controls">
@(new HtmlString(@Html.TextBoxFor(model => model.time_start, new { @placeholder = "08:00 AM", id = "time_start" }).ToString()))
@Html.ValidationMessageFor(model => model.time_start)

</div>
</div>
</div>
</div>

<div class="row-fluid">
<div class="span6 ">
<div class="control-group">
<label class="control-label">Time End:</label>
<div class="controls">
@(new HtmlString(@Html.TextBoxFor(model => model.time_end, new { @placeholder = "01:00 PM", id = "time_end" }).ToString()))
@Html.ValidationMessageFor(model => model.time_end)

</div>
</div>
</div>
</div>

<div class="row-fluid">
<div class="span6 ">
<div class="control-group">
<label class="control-label">Allday Event:</label>
<div class="controls">
@Html.DropDownListFor(model => model.allDay,

new List<Object>{

new { value = "true" , text = "Yes" },
new { value = "false" , text = "No"}
}, "value", "text", "-"), new { id = "allDay" })
@Html.ValidationMessageFor(model => model.allDay)

<i class="icon-plus"></i>

</p>

</div>
</div>
</div>

</div>
}


<script>
$(document).ready(function () {

var date = new Date();

$("#datepicker_start").datepicker({
numberOfMonths: 1,
minDate: date,
onSelect: function (selected) {
$("#datepicker_end").datepicker("option", "minDate", selected)
}
});

$("#datepicker_end").datepicker({
numberOfMonths: 1,
minDate: date,
onSelect: function (selected) {
$("#datepicker_start").datepicker("option", "maxDate", selected)
}
});

function disableTextBox() {

var allDay = document.getElementById("allDay");
var time_start = document.getElementById("time_start");
var time_end = document.getElementById("time_end");

if (allDay == "true") {
time_start.disabled = true;
time_end.disabled = true;
}
}
});
</script>

非常感谢对此问题的任何帮助非常感谢

最佳答案

您有函数disableTextBox的声明,这对于完成您的任务来说很好,但我不知道您在哪里调用它。如果您需要在 dropDownList 的值发生变化时调用它 - 您需要将其作为更改事件的处理程序调用:

$("#allDay").change(disableTextBox);

但我认为你应该使用 jQuery 并尝试这样的事情:

$("#allDay").change(function(){
if($(this).val() == "true")
{
$("#datepicker_start").attr("disabled", "disabled");
$("#datepicker_end").attr("disabled", "disabled");
}
});
