答案 0 :(得分：1)
在DOM完全加载之前，您的 $("ul.tree")正在执行，jQuery无法看到它。我相信将这段代码移动到onload事件，或移动到DOM的底部它将起作用。
好的......我相信我现在知道了。
$('.check-all').live('change', function(){
$('.options').find('input[class=def]').attr('checked', true);
//This line should select the ones marked with the class ".def"
$('ul.tree').find('input.def').siblings("div.checkbox").click();
return false;
});
我还值得注意的是，我从jquery-checktree重新下载了这个插件。
