I have been struggling to get the following components to work together without success. The goal is to populate the mediaId's combobox with respective values based on the selection in the target combobox. Currently, I am only simulating the values for the mediaId combobox. Could someone please guide me on how to properly integrate them? Thank you in advance.
The Medium.cshtml view:
<script src="@Url.Content("~/Scripts/PartialLoad.js")" type="text/javascript"></script>
<div class="editor-label">
@Html.LabelFor(model => model.Files[i].TargetId)
</div>
<div class="editor-field">
@Html.DropDownListFor(model => model.Files[i].PTargetId, (ViewData["targets"] as SelectList).MakeSelection(Model.Files[i].PTargetId))
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Files[i].MediaId)
</div>
<div class="editor-field">
@Html.DropDownListFor(model => model.Files[i].MediaId, (ViewData["mediaIds"] as SelectList).MakeSelection(1))
</div>
The javascript partialload.js
$(document).ready(function () {
$("#targets").change(function () { GetMValues("#targets", "#mediaIds"); });
});
function ClearDrop(objSource) {
$(objSource).empty();
}
function GetMValues(objSource, objDest) {
var url = '/GetMValues/';
$.getJSON(url, { id: $(objSource).val() },
function (data) {
ClearDrop(objDest); $.each(data, function (index, optionData) {
$(objDest).append("<option value='" + optionData.Value + "'>" + optionData.Text + "</option>");
});
});
}
The homecontroller.cs
public ActionResult GetMValues(String id)
{
int myId = 0;
int.TryParse(id, out myId);
var mediumIds = new List<long>();
int max = myId + 3;
// just to emulate the data in the list
for ( long l = 1 ; l < max ; l++ ){
mediumIds.Add(l);
}
var select = new SelectList(mediumIds, "PTargetId", "TargetId");
return Json(select, JsonRequestBehavior.AllowGet); //allow get needed to allow get calls
}
