Javascript if语句将不执行MVC3 / razor

Question

I have the following code:

<script type="text/javascript">
    if ('@(Model.DidPass)' == 'True') {
        alert('Blah Blah True');
    }
    else {
        alert('Blah blah false');
    }
</script>

in Fiddler I can see that my if statements renders in the browser as:

if ('True' == 'True')

yet for some reason the alert('Blah blah blah True') will not execute. If I step through the code in VS I can watch it get as far as the if statement then just bug out. Any thoughts?

Answer 1

Your going to need to transition from code to html like so. Otherwise the compiler will assume that alert is ac# method call (which it isn't) and you'll get a compiler error when you attempt to use it.

<script type="text/javascript">
    @if(Model.DidPass){
        @:alert('Blah Blah True');
    } else {
        @:alert('Blah blah false');
    }
</script>

Alternatively you can use the psuedo element <text></text> if your javascript takes up more than one line. The @: is only for the text following all the way until a newline.

Did you try:

    if (Boolean('@(Model.DidPass)') == true) {
        alert('Blah Blah True');
    }
    else {
        alert('Blah blah false');
    }

Answer 3

Eh.. that's not how i'd do it but, since you are going to do it that way why don't you just do:

<script type="text/javascript">
   alert('@(Model.DidPass ? "blahblahblah true" : "blahlbahlbah false")');
</script>

edit : fixed code by rolling it back to a ternary..

Answer 4

Try === instead maybe?

Never used this MVC3/razor stuff ( or even know what it is ), so this is just a guess
