Question

@Purmou

嗨，请考虑以下html5文件。 div仍然位于0,0，边界也没有出现。我已尝试对随附的各种更改，但似乎无效。

非常感谢Purmou和所有其他人阅读本文的帮助。问候，sbguy

尝试使用：

jQuery("#div1A").css({
    "position":"absolute", 
    "top": $("#div1A").offset().top + "px",
    "left": $("#div1A").offset().left + "px",
});

编辑：您显然希望将变量div1A_top和div1A_left设置为top和left CSS值：

jQuery("#div1A").css({
    "position":"absolute", 
    "top": div1A_top + "px",
    "left": div1A_left + "px",
});

无法使用jQuery为我的div设置绝对位置
