To implement @Html.CspScriptNonce() in the <a> tag with the href attribute “javascript:Account.uitloggen();”, you need to use a server-side templating engine that supports the CspScriptNonce() function. One such example is ASP.NET MVC. Here’s how you can modify your code:

<a href="javascript:Account.uitloggen();" nonce="@Html.CspScriptNonce()"><i>Stop</i></a>

In the above code, @Html.CspScriptNonce() is a server-side code snippet that generates the nonce value dynamically. The nonce attribute is then assigned the value returned by the CspScriptNonce() function. This ensures that the generated nonce value is used for the <a> tag, which helps maintain the Content Security Policy (CSP) integrity.

Please note that @Html.CspScriptNonce() is specific to ASP.NET MVC and may not be available in other server-side frameworks or templating engines. If you’re using a different framework, please consult its documentation to find the equivalent function for generating the nonce value.
