如何在表中将td高度设置为0px? [英] How to set td height to 0px in a table?
问题描述
我有一个包含几行的HTML表(这是动态构建的)。所有< tr>
s都有一个< td>
里面。
如果一个< td>
里面没有HTML内容,我希望它不可见。
这怎么做? (不是说HTML内部是动态呈现的,我不想使用 display:none
或< td>
或< tr>
)。
代码示例:
< html>
< body bgcolor =#E6E6FA>
< table cellSpacing =0cellPadding =0>
< tr>
< td>一个单元格< / td>
< / tr>
< tr>
< td bgcolor =#FF0000>< / td>
< / tr>
< tr>
< td>两个单元格< / td>
< / tr>
< / table>
< / body>
< / html>
在Firefox中,空TD是不可见的。然而,在IE中,TD的高度为1像素: b
$ b
使用DOM Inspector查看我发现它需要1个像素:
如何设置TD不可见?你可以使用CSS伪选择符:empty > / code>:
#myDynamicTable td:空
{
显示: 没有;

如果你想支持IE< 9:
var ieVer = getInternetExplorerVersion();
if(ieVer!= -1& ieVer <9.0){
//对于IE< 9支持
var dynamicTable = document.getElementById(myDynamicTable);
var TDs = dynamicTable.getElementsByTagName(td);
for(var i = 0; i< TDs.length; i ++){
if(TDs [i] .innerHTML ==){
TDs [i ] .style.display =none;
}
}
}

函数getInternetExplorerVersion()
//返回Internet Explorer的版本或-1
//(表示使用其他浏览器)。
{
var rv = -1; //返回值假定失败。
if(navigator.appName =='Microsoft Internet Explorer'){
var ua = navigator.userAgent;
var re = new RegExp(MSIE([0-9] {1,} [\.0-9] {0,}));
if(re.exec(ua)!= null)rv = parseFloat(RegExp。$ 1);
}
return rv;
}

I have an HTML table containing a few rows (this is built dynamically). All <tr>
s have one <td>
inside.
If one <td>
doesn’t have HTML content inside, I would like it to be invisible.
How can this be done? (Not that the HTML inside is rendered dynamically and I do not want to use display:none
or any other property on the <td>
or <tr>
).
Code sample:
<html>
<body bgcolor="#E6E6FA">
<table cellSpacing="0" cellPadding="0">
<tr>
<td>one cell</td>
</tr>
<tr>
<td bgcolor="#FF0000"></td>
</tr>
<tr>
<td>two cell</td>
</tr>
</table>
</body>
</html>
In Firefox the empty TD is invisible. However, in IE the TD takes up 1 pixel in height:
Looking with DOM Inspector I see that it takes 1 pixel:
How can I set the TD not to be visible? Any scripts I can execute inside the TD?
You can use the CSS pseudo selector :empty
:
#myDynamicTable td:empty
{
display: none;
}

And if you want to support IE<9:
var ieVer = getInternetExplorerVersion();
if (ieVer != -1 && ieVer < 9.0) {
// for IE<9 support
var dynamicTable = document.getElementById("myDynamicTable");
var TDs = dynamicTable.getElementsByTagName("td");
for (var i = 0; i < TDs.length; i++) {
if (TDs[i].innerHTML == "") {
TDs[i].style.display = "none";
}
}
}

function getInternetExplorerVersion()
// Returns the version of Internet Explorer or a -1
// (indicating the use of another browser).
{
var rv = -1; // Return value assumes failure.
if (navigator.appName == 'Microsoft Internet Explorer') {
var ua = navigator.userAgent;
var re = new RegExp("MSIE ([0-9]{1,}[\.0-9]{0,})");
if (re.exec(ua) != null) rv = parseFloat(RegExp.$1);
}
return rv;
