I’ve created a test page that mimics the problem I am getting on my actual page.<\/p>\n

As you can see in doSomething2()<\/code>, the dfd object is deliberately never resolved. However, when I run the following code, the .done()<\/code> in doSomething()<\/code> always fires. Inspecting the console, you will see that dfd.isResolved()<\/code> is false<\/em> right before .done()<\/code> runs.<\/p>\n

Any insights? Any help is appreciated<\/p>\n

edit: I UNDERSTAND that this function accomplishes nothing. I’ve just made an example to replicate my problem. I UNDERSTAND that fetching ‘google.com’ is against SOP. I’ve just created this example to replicate my problem. I am developing a web app that is meant to run locally from one html file. In this case, SOP is not strictly adhered to, so this should be ok to at least test.<\/p>\n
edit:I’ve created a jsfiddle to test this behavior:<\/strong> http:\/\/jsfiddle.net\/Sgwpv\/2\/<\/p>\n

    Your problem is this passing in a statement to .done rather then a function<\/p>\n
    see live example<\/p>\n
    Internally, .done<\/code> takes a list of functions and pushes them to a callback array so<\/p>\n
    callbacks.push(elem);<\/code><\/p>\n
    You pass in a statement as elem<\/code> and get<\/p>\n
    callbacks.push(alert(\"foo\"));<\/code><\/p>\n
    Your pushing the return value of the statement (in this case undefined<\/code>) to the callback array rather then a function.<\/p>\n<\/li>\n<\/ol>\n
