如何在：remote form_tag上指定“每次调用”的jQuery AJAX选项？

Question

I have a simple form (that's enabled using ujs to make an ajax call with jQuery). I would like to specify the DataType of the response (by default it doesn't seem to pay much attention to "text", and I'm getting a jQuery.ajaxError.

How/where do I specify the DataType? (I don't want to specify it for all calls, just a particular one.)

Answer 1

dataType is declared in the ajax call.

$.ajax({
    url: 'myurl.com/script.php',
    type: 'GET',
    dataType: 'json',
    data: 'a=1&b=2',
    success: function(){
        alert('Great Success!')
    },
    error: function(){
        alert('Bummer.')
    }
});

Or whatever your call looks like since you didn't bother to post it... >:(

In your script, make sure you echo json_encode(); whatever data it is you're working with.

Ugh

... form_tag ... :'data-type' => 'text' ...

I'm sure jQuery has this documented "somewhere", but I was unable to find it at this time. (re: jQuery and html5 data-* attributes)
