underscore js template does not work

this should be easy or simple, but I donot know why it doesnot work. I waste here about 1 whole day.

https://jsfiddle.net/panyongfeng/m73vnz9j/

<script>
        var tpl = "hello: <%= name %>";
        var compiled = _.template(tpl);
        compiled({
            name: "dadf"
        });
        alert(compiled());
</script>

I just get "hello result", which should be hello dadf. Would you please point out what's wrong? thanks

Your code is right but if you want to use the result then you need to store the result of compiled method. So your code should be -

var dump = compiled({ name: "dadf" });
alert(dump);

You're misunderstanding the examples in the documentation. When they say this:

var compiled = _.template("hello: <%= name %>");
compiled({name: 'moe'});
=> "hello: moe"

The context is that they're working inside a REPL as though they ran node from the command line. That means that the stuff after => is the result of the last expression and the hello: moe string is what compiled({name: 'moe'}) returns. Running the template function returns the filled in template as a string, it doesn't stash the results anywhere.

You want to drop the last alert call in favor of this:

alert(compiled({ name: "dadf" }));
