I had Public declared Dictonary in code behind as
:
Public dics As New
Dictionary(Of String, String()) From { _
{"picture", New String() {".jpeg", ".jpg",
".png", ".bmp", ".gif", ".tif"}}, _
{"document", New String() {".doc", ".docx",
".txt", ".htm", ".html", ".xml", ".xaml",
".css"}}, _
{"excel", New String() {".xls", ".xlsx",
".xlt", ".xla"}}, _
{"pdf", New String() {".pdf"}}, _
{"zip", New String() {".7z", ".APK",
".BAT", ".rar", ".dll", ".jar", ".zip"}},
_
{"ppt", New String() {".ppt", ".pos",
".pps"}}}Edit :
if i do like this
function myFunction() {
var dic = "<%= dics %>";
var array_keys =new Array();
var array_values = new Array();
for (var key in dic) {
alert(key);
}
}How can i access this Dictonary in javascript to do
some operations

05-Feb-2015For now it looks like you need to serialize dictionary into javascript object and then paste it in your JavaScript. You could use any library for serialization. E.g. Newtosoft.Json. Like this:
function myFunction() {var dic = <%= Newtonsoft.Json.JsonConvert.SerializeObject(dics) %>;
var array_keys = new Array();
var array_values = new Array();
for (var key in dic) {
alert(key);
}
}
Note that I removed quotes.
But I suggest you to get rid of this approach and not mix JavaScript and ASP.Net code. So in my vision you should load this dictionary via AJAX or if it's not possible place ASP.Net in some other place. E.g.:
View:
JavaScript:
function myFunction() {var dicInput = document.getElementById('dictionaryInput');
var dic = JSON.parse(dicInput.value);
var array_keys = new Array();
var array_values = new Array();
for (var key in dic) {
alert(key);
}
}
Hope it will help.
