$("#tableEmail td[background-color = dodgerblue]");但是就是没有结果。其它的几个属性也用了，如：bgColor，background和backgroundColor，但还是不行，不知道为什么，用filter或not也不行。谁知道怎么写？程序逻辑应该没问题的。另外说一下上面几个背景色的应用场合和区别，我觉得还是不要混用为好。 回复讨论(解决方案)
background-color为rgb格式，不是dodgerblue
建议你使用class设置背景颜色
你可以这样
var x = $('#tableEmail td').filter(function() {
return $(this).css('background-color') == 'rgb(30, 144, 255)';
})
x.html("xxxxxxx")
x就是那个td
IE中这样写
$('#tableEmail td').filter(function() {
return $(this).css('background-color') == 'dodgerblue';
})
例子
<html><head><script src="jquery-1.9.1.min.js"></script></head><body> <table id="tableEmail"> <tr> <td style="background: dodgerblue">sdsd</td> <td style="background: red">sdsd</td> </tr> </table> <input type=button value=test onclick="xx()"> <script> function xx() { alert($('#tableEmail td').css("background-color")) $('#tableEmail td').filter(function() { return $(this).css('background-color') == 'dodgerblue'; }).html("xxxxxxx") } </script></body></html> 你可以这样
var x = $('#tableEmail td').filter(function() {
return $(this).css('background-color') == 'rgb(30, 144, 255)';
})
x.html("xxxxxxx")
x就是那个td
IE中这样写
$('#tableEmail td').filter(function() {
return $(this).css('background-color') == 'dodgerblue';
})
例子
<html><head><script src="jquery-1.9.1.min.js"></script></head><body> <table id="tableEmail"> <tr> <td style="background: dodgerblue">sdsd</td> <td style="background: red">sdsd</td> </tr> </table> <input type=button value=test onclick="xx()"> <script> function xx() { alert($('#tableEmail td').css("background-color")) $('#tableEmail td').filter(function() { return $(this).css('background-color') == 'dodgerblue'; }).html("xxxxxxx") } </script></body></html> 确实是的，我测试了一下，IE将background-color解析成颜色名，而Chrome， Firefox和Safari都解析成rgb值。我想问能有通过颜色名得到rgb的方法吗。还有就是我用
var select = td.filter(function () { return $(this).css("background-color") == "rgb(30, 144, 255)" }); select.next（）得到下一个单元格，可就是为空，不知道怎么回事。 有2个方法
1，使用Color.js，下载使用方法参见name2rgb http://matthewbj.github.io/Colors/
2，使用json预定义

谢谢你，还有就是为什么select.next（）得不到下一个单元格？

谢谢你，还有就是为什么select.next（）得不到下一个单元格？
我知道为什么了，因为各个td位于不同的tr中，并不是兄弟关系，而我的td都只有1个，所以select.next()为空。正确的做法是select.parent().next().children().first()，先得到父元素tr，然后得到下一个tr，再得到tr所有子元素td，最后得到第一个子元素td即我们看到的下一个单元格了。
