I have a function in c# that builds dictionary ,I need to pass this dictionary to my java-script function.
This is what I have tried
My server function
public partial class login : System.Web.UI.Page
{
protected Dictionary<string, string> GetTradingTypeToSelect()
{
Dictionary<string, string> dict = new Dictionary<string, string>();
try {
string Types =GetString("some text);
var items = Types.Split(new[] { ';' }, StringSplitOptions.RemoveEmptyEntries)
.Select(s => s.Split(new[] { '=' }));
foreach (var item in items)
{
dict.Add(item[1], item[0]);
}
//this working 100%
}
catch (Exception ex)
{
}
return dict;
}
}
My client:
$(document).ready(function () {
$("#Account").keyup(function () {
var TradingTypeToSelect = '<%=GetTradingTypeToSelect();%>';
//TradingTypeToSelect is equals to string '<%=GetTradingTypeToSelect();%>'
var test = TradingTypeToSelect[0].key;
var test2 = TradingTypeToSelect[0].value;
});
});
What am I missing here?

You can create a [WebMethod] in the code behind and call it from javascript using $.ajax.Below is a complete example:
Code behind:
[System.Web.Services.WebMethod]
public static Dictionary<string, string> GetTradingTypeToSelect()
{
var dict = new Dictionary<string, string>();
dict.Add("1", "Item 1");
dict.Add("2", "Item 2");
return dict;
}
.ASPX:
<head runat="server">
<title></title>
<script src="//code.jquery.com/jquery-1.12.3.min.js"></script>
<script type="text/javascript">
$(function () {
$("#Account").keyup(function () {
$.ajax({
type: "POST",
url: "AjaxCallExample.aspx/GetTradingTypeToSelect",
contentType: "application/json;charset=utf-8",
success: function (data) {
alert(data.d["1"]);
alert(data.d["2"]);
},
error: function (errordata) {
console.log(errordata);
}
});
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<input id="Account" type="text" />
</form>
</body>
