[英]create array in javascript with Html.action
我試圖通過在MVC控制器中調用一個函數並傳回字符串數組來在javascript中創建字符串數組。 這完全是行不通的,我不確定我需要做些什么來對此進行修改。 在下面,您可以看到我的JavaScript和控制器代碼。 任何幫助是極大的贊賞
JavaScript的:
var optionString = @Html.Action("PopulateDashboardDropdown", "Embed", new { Dashboards = Model[0][0].Dashboards });
控制器:
public string[] PopulateDashboardDropdown(ODataResponseListDashboard[] dashboards)
{
string email = "";
//loop that finds the groupID assigned to the currently logged in user
foreach (Claim claim in ClaimsPrincipal.Current.Claims)
{
if (claim.Type == "emails")
{
email = claim.Value;
email = email.ToLower();
}
}
string[] orgs = GetOrgs(email);
string[] retVal = new string[orgs.Length];
bool[] admin = new bool[orgs.Length];
for (int i = 0; i < orgs.Length; i++)
{
admin[i] = isAdmin(orgs[i], email);
retVal[i] = "";
}
//loop that creates a string to emulate the innerHtml of a dropdown selector based on the names of all dashboards in the workspace
for (int i = 0; i < orgs.Length; i++)
{
for (int j = 0; j < dashboards[i].Value.Count; j++)
{
if (dashboards[i].Value.ElementAtOrDefault(j).DisplayName.Contains("Admin"))
{
if (admin[i])
{
retVal[i] += "<option>" + dashboards[i].Value.ElementAtOrDefault(j).DisplayName + "</option>";
}
}
else
{
retVal[i] += "<option>" + dashboards[i].Value.ElementAtOrDefault(j).DisplayName + "</option>";
}
}
}
return retVal;
}
好吧,從不清楚是什么錯誤或到底發生了什么,但是我看到了幾個問題。 我建議以下內容以修復代碼:
1)將控制器方法的結果更改為JsonResult:
public JsonResult PopulateDashboardDropdown(ODataResponseListDashboard[] dashboards)
{
...
return this.Json(retVal);
}
2)通過ajax調用獲取數據(注意:您需要以http格式插入正確的url。Http.Action / Razor在javascript中不起作用):
$.getJSON(myUrl, function (data) {
var optionString = data;
...
});
