我有以下CSS:
.foo .bar {
background: red;
}
它可以很好地处理以下HTML:
<div class="foo">
<div class="bar">I have a red background</div>
</div>
但是当我不在父/子关系中时,我似乎找不到重用CSS定义的方法。例如,如何将相同的CSS应用于以下DIV:
<div class="???">I want a red background!</div>
让我们假设我有一个像下面这样的问题。有没有办法只用CSS来选择,只选择direction: rtl样式的元素?提前感谢!
.rightToLeft {
direction: rtl;
}
.leftToRight {
direction: ltr;
}
/* Is there is any simple way to select all of the 3 different spans with the dirction=rtl property? */
<span class="rightToLeft">This is RtL, </spa
<a myattr="something">anchor</a>
<a>anchor</a>
$(a[myattr]) does not work
$(a[myattr!="") does not work
$(a[myattr!==undefined) does not work
如何才能获得那些"myattr“已定义且等于某个值的锚点?
我有一个带有NOT EXISTS的SQL查询,用于从最终结果中排除一组特定的值。
select distinct
from [rpt_StockInventorySummary] a
where a.[DepartmentId] ='P'
and not exists (
select *
from rpt_StockInventorySummary b
where b.DepartmentId = 'p'
and b.Manufacturer = 'warrington'
and b.LowestGroup = 57 and b.Insto
我有以下(无用)代码,它应该选择当前Flash文档中的每个文本元素:
fl.outputPanel.clear();
var textFieldArray = fl.findObjectInDocByType("text", fl.getDocumentDOM());
fl.trace(textFieldArray.length);
for (var i=0; i < textFieldArray.length; i ++){
fl.selectElement(textFieldArray[i]);
}
令人惊讶的是,这会导致一个错误。
