影响CSS规则的JavaScript/jQuery函数
我正在尝试编写基于表数据生成网格的函数。该函数可以工作,但由于某些原因,这些类不会导致样式更改。我的函数如下所示:影响CSS规则的JavaScript/jQuery函数,javascript,jquery,html,css,Javascript,Jquery,Html,Css,我正在尝试编写基于表数据生成网格的函数。该函数可以工作,但由于某些原因,这些类不会导致样式更改。我的函数如下所示: $(document).ready(function() { // create 9:00 and 9:30 cells for both employees generateAvailabilityGrid($("#oneDay"), 30, 9, 10); }); /* NOTE: This function works as expected.

我认为我的代码的问题在于试图将类和鼠标单击侦听器添加到for循环内部创建的临时对象。以下是SSCCE:
这是否意味着在单元格添加到表div之后,我必须定义for循环之外的所有内容?如果是,原因是什么?问题在于css规则是按选择器的特定性排序的 您的类本身不够具体,无法排名高于用于设置背景的默认规则。这可以很容易地在浏览器开发工具css检查器中检查任何元素,并且影响元素的规则将按其排名顺序显示 试一试
