使用chrome.downloads.cancel：

chrome.downloads.onDeterminingFilename.addListener(function (item, suggest) {
    suggest({
        filename:item.filename,
        conflict_action: 'prompt',
        conflictAction: 'prompt'
    });

    if(true) { // your cancel condition
        chrome.downloads.cancel(item.id);
    }
});

是的，您仍然需要打电话，suggest因为只有正在进行的项目可能会被取消。
