我想填充从数据库中获取数据的文本框。当我使用下拉列表选择任何值时,我需要从下拉列表中获取ID并调用填充@Html.EditorFor(model => model.taskName)
的函数。该页面没有变化。怎么可能?
<div class="form-group">
@Html.LabelFor(model => model.jobID, "jobID", new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.DropDownList("jobID", String.Empty)
@Html.ValidationMessageFor(model => model.jobID)
</div>
</div>
<div> @Html.Partial("../Location/taskname") </div>
</div>
taskname.cshtml
@Html.AntiForgeryToken()
<div class="form-horizontal">
@Html.ValidationSummary(true)
<div class="form-group">
@Html.LabelFor(model => model.taskName, new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.taskName)
@Html.ValidationMessageFor(model => model.taskName)
</div>
</div>
</div>
答案 0 :(得分:1)
让你的下拉列表如下:
@Html.DropDownList("jobID", null, new {@id="job"})
和任务名称文本框:
@Html.EditorFor(model => model.taskName, new {@id="taskname"})
这样做,为下拉列表索引更改事件编写jquery事件,并发送ajax调用以获取从下拉列表中选择的作业ID的任务名称:
$('select#job').change(function(){
var JobId =$(this).val();
// Send Ajax call and get Task name
var Url = 'http://example.com/Controller/Action/?jobid='+JobId ;
$.ajax({
url: Url ,
success: function(result) {
$('input#taskname').val(result);
},
error: function(error) {
alert(errorss);
}
});
});
