How to pass a classic asp session variable array to client side JavaScript?

I 开发者_如何学JAVAhave a Session variable which is an array of integers, for example:

myArray{1,4,3,5,6,7,9,2,...n}

What I am trying to do is pass this in a session var <%=Session("myArray")%> to my clientside javascript. I can do it if I take the session var and convert it to a string like this:

    var b = '<%=Session("myArray")%>';
    var bob = new Array();
    bob = b.split(',');

I am just wondering if there is a more direct way of passing the array possibly cutting out the need to convert it to a string before passing so I can just pass it as an array?

Thanks

you could parse the integers into something that is already an array, so you bob array woul be like that:

var bob = [<%=GetIntegersString(Session("myArray"))%>];

when the page is served to the client it should look like this:

var bob = [1,4,3,5,6,7,9];

the function GetIntegersString is something you will need to implement

This should work just fine:

var bob = [<%=Join(Session("myArray"), ", ")%>];

JSON is Javascript's way of expressing a literal value, so you could convert your array to json, and then assign it directly:

var bob = '<%=array_to_json(Session("myArray"))%>';

http://www.json.org recommends some ASP utilities to convert data to json:
