如何停止基于CSS值的jquery动画?

So, I have two divs: #div1 and #div2. I want '#div2' to disappear when '#div1' has the CSS value: top = 0px.

我有两个div: #div1和#div2。当#div1的CSS值为:top = 0px时，我希望#div2消失。

Here is the CSS:

CSS:

#div1 {
    top: 0px;
}
#div2 {
    display: block;
} 
if ( $('#div1').css('top') == '0px' ) {
    $("#div2").hide();
} else {
    $("div2").fadeIn();
}
$("div2").click(function(){
        $("#div1").animate({top:"+=315px"}, "slow");
});

The problem I am running into is that I'm changing that CSS value (for #div1) via Javascript and for this reason, my js doesn't acknowledge the change and doesn't make the div disappear (I think). Is there any way to make #div2 disappear when #div1's CSS property top = 0 and reappear whenever it is changed? Or is there a better way to implement this?

我遇到的问题是，我正在通过Javascript修改CSS值(对于#div1)，出于这个原因，我的js不承认这个更改，也没有使div消失(我想)。当#div1的CSS属性top = 0时，是否有办法使#div2消失，并且当它被更改时重新出现?或者有更好的方法实现它吗?

rather than using this use method .position()

而不是使用这个use方法。position()

<script>
var p = $("#div1");
var position = p.position();
alert( "left: " + position.left + ", top: " + position.top );
</script>
