从视图将angularjs变量传递给nodejs函数

Question

Is it possible to pass angularjs variable to a nodejs function from view like below

// View
<div ng-repeat="user in users">
    <img src="<%getUserImage(user)%>">
 </div>

// Server
app.locals.getUserImage = function (user) {
    if (user.url) { return user.url; };
    return "/images/no-user.png";
}

I have the following error: Cannot read property 'url' of undefined

Can anyone help please ?

Thank you

Answer 1

Why don't you perform this operation in the view instead of having to call the server function?

Just like this

<img ng-src="{{ user.url || '/images/no-user.png' }}"/>
