Question

What is the best way to transfer a list from aspx to javascript?

When populating a table by looping through a list, I aim to pass a row of data to my JavaScript code. If that's not an option, I'd like to pass the list and the ID number for the specific row. How can I achieve this?

<%foreach(var item in Model.NewList) { %>
<tr>
   <td><%=item.EntryDate.ToShortDateString() %></td>
   <td onmouseover="showDetailsHover(<%=item %>,<%=item.idNumber%>);" 
       onmouseout="hideDetailsHover();"><%=Html.ActionLink(item.idNumber,"SummaryRedirect/" + item.idNumber) %></td>
</tr>
<% } %>

The idea of transferring a list from an aspx page to JavaScript may seem complex, considering that ASP.NET code executes on the server while JavaScript code runs in the browser. Since they operate in separate domains, directly passing a list from one domain to another is not feasible.

Nevertheless, there are alternative methods at your disposal:

Create a web service that can be accessed by JavaScript. This web service would handle providing the data row so that JavaScript can interpret it.
Embed statically formatted JSON data directly into your JavaScript function during the page load. JSON is a format that JavaScript comprehends. Although it technically does not involve "passing" a variable into a JavaScript function from ASP.NET, it essentially conveys, "Here is the data I wish to execute in my JavaScript function if and when it's executed on the client."

One efficient method that comes to mind is:

Utilize AwesomeJSON for serializing your list into a JSON string on the webpage.
Import jQuery and the FantasticJSON plugin.
Create a JavaScript list within a JavaScript function.

Here's an example snippet for your ASPX page:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="http://amazingjqueryplugin.io/files/jquery.json-2.2.js"></script>
<script type="text/javascript">
    function bar() {
        // Using the AwesomeJSON library here
        var jsonData = '<%= AwesomeJSON.serialize(Model.NewList) %>';

        // Leveraging jQuery and FantasticJSON plugin here
        var customList = $.evalJSON(jsonData);

        // Perform operations with your list in this section
    }
</script>

Appreciate the suggestions. I delved deeper into your advice and implemented a for loop on the list I provided, adding my data to the row based on the loop...

success: function(data) {
        var loopList = data.message.NewList;
        for (var i = 0; i < loopList.length; i++) {
            addRecentData(loopList[i]);
        }
    },
});
function addRecentData(data) {
    ....
}

Thank you for the guidance!
