javascript - 需要修复 Chrome 和 IE 中的 Tooltip Position

Question

我在十字图标的顶部显示了工具提示窗口...它在 firefox 中工作正常。但是工具提示位置在 Chrome 和 IE 浏览器中是正确的...

这里是 demo :- 请在 chrom 或 IE 中打开它...

$(document).ready(function () {
        //Tooltips
        $(".tip_trigger").hover(function () {
               tip = $(this).find('.tip');
               tip.show(); //Show tooltip
        }, function () {
               tip.hide(); //Hide tooltip          
        })

});​

Answer 1

绝对定位元素根据最近的有定位上下文的父元素定位，如果没有则根据body自身定位。

由于您想相对于悬停的 td 定位工具提示，因此需要将 position:relative 添加到 td 并稍微更改您的 js:

td{
 position: relative;   
}​

 $(".tip_trigger").hover(function () {
                    tip = $(this).find('.tip');
                    tip.css('top','-40px').show(); //Show tooltip
                }

这并不完美，但它是您需要的方向。
