Adding a namespace in a .js file

In the MVC application I'm developing, all JavaScript for the pages is stored in separate JavaScript files without any script tags on the pages. There's a Messages class containing Errors, Information, and Confirmation classes with static strings. While error and information messages are fetched from the server, confirmation messages like "Do you wish to Save (OK/Cancel)" are hardcoded in each JavaScript file. I now want the JavaScript code to utilize the confirmation messages from the Messages.Confirmation class.

To address this issue, I currently implement the following solution on my page:

<%@ Import Namespace="Business.Common" %> 

.....

<script type="text/javascript">
    confirmSaveQuestion = '<%= Messages.Confirmations.CONFIRM_SAVE  %>';
</script>

Meanwhile, my .js file is structured as follows:

var confirmSaveQuestion;

function ConfirmSave() {
    var result = window.confirm(confirmSaveQuestion);
    if (result)
        return true;
    else
        return false;
}

This setup works effectively, but I'm curious about the possibility of importing the Business.Common namespace into the .js file directly. This way, I wouldn't need to define the value for confirmSaveQuestion on my page.

Answer №1

Your .js files are static, meaning they cannot interact with server code. Here are a couple of suggestions:

1) Implement an ASHX handler to dynamically generate javascript files. This way, you can inject server-side data into your javascript. Instead of linking a .js file in your HTML, reference your .ashx file.

2) Alternatively, include <%= %> tags in your master page. This will display the content on the page, but you only need to handle them once.

Answer №2

Since I couldn't figure out how to import a namespace into my .js file, I decided to take a different approach. Instead of using script tags on my page, I added this line of code. It seems to achieve a similar outcome, but in a more streamlined manner.

<% Html.Telerik().ScriptRegistrar().OnDocumentReady("confirmSaveQuestion = '" + Messages.Confirmations.CONFIRM_SAVE + "'"); %>
