如何动态改变tabe单元格的文字颜色？ [英] How to change dynamically tabe cell text colors?
问题描述
我需要一个解决方案，通过JavaScript动态更改表格单元格的文本颜色。文本可以是以下颜色：蓝，绿，红和黑。
p>< HTML>
< head>
< title>< / title>
< meta http-equiv =content-typecontent =text / html; charset =UTF-8>
< script src =jquery-mobile / jquery-1.6。 4.min.jstype =text / javascript>< / script>
< script src =jquery-mobile / jquery.mobile-1.0.min.jstype =text / javascript >< / script>
< / head>
< body>
< div data-role =pageid =page>
< div data-role =content>
< table width =100％border =0id =friendsclass =menu>
< tr id =friend1>
< td>名字< / td>
< td>姓< / td>
< / tr>
< tr id =friend2>
< td>名字< / td>
< td>姓氏< / td>
< / tr>
< tr id =friend3>
< td>名字< / td>
< td>姓< / td>
< / tr>
< tr id =friend4>
< td>名字< / td>
< td>姓氏< / td>
< / tr>
< tr id =friend5>
< td>名字< / td>
< td>姓氏< / td>
< / tr>
< / table>
< / div>
< / div>
< / body>
< / html>
如何更改文字颜色？条件是，我可以通过JavaScript动态地做到这一点，并且不止一次。这意味着我需要设置一种颜色（例如红色），稍后将颜色重置为黑色并将其设置为其他颜色（例如蓝色）。
我看到一些示例通过id设置颜色，但我没有办法将此示例转移到表格单元格，并且每个单元格可以具有不同的颜色。
有人可以帮我吗？
您可以通过所有td的
var tds = document.getElementsByTagName（td）; （var i = 0，j = tds.length; i
;
或
您可以通过td它们是特殊元素的子元素：
var myNode = document.getElementById（friend2）;
var tds = myNode.getElementsByTagName（td）; （var i = 0，j = tds.length; i
;
问候！
I need a solution to change dynamically via javascript the text color of table cells. The text can be the following colors: blue, green, red and black.
Table example:
<html>
<head>
<title></title>
<meta http-equiv="content-type" content="text/html; charset="UTF-8">
<script src="jquery-mobile/jquery-1.6.4.min.js" type="text/javascript"></script>
<script src="jquery-mobile/jquery.mobile-1.0.min.js" type="text/javascript"></script>
</head>
<body>
<div data-role="page" id="page">
<div data-role="content">
<table width="100%" border="0" id="friends" class="menu">
<tr id="friend1">
<td>First name</td>
<td>Surname</td>
</tr>
<tr id="friend2">
<td>First name</td>
<td>Surname</td>
</tr>
<tr id="friend3">
<td>First name</td>
<td>Surname</td>
</tr>
<tr id="friend4">
<td>First name</td>
<td>Surname</td>
</tr>
<tr id="friend5">
<td>First name</td>
<td>Surname</td>
</tr>
</table>
</div>
</div>
</body>
</html>
How can I change the text color? Conditions are, that I could do this dynamically via javascript and more than one time. That means I need to set a color (e.g. red), later reset the color to black and set it following to another color (e.g. blue).
I saw some examples with setting the color via id, but I found no way to transfer this example to table cells and each cell could have different colors.
Can someone help me?
you can go through all td's
var tds = document.getElementsByTagName("td");
for(var i = 0, j = tds.length; i < j; ++i)
tds[i].style.color = "#00AA00";
OR
you can go through td's that are childs of a special element:
var myNode = document.getElementById("friend2");
var tds = myNode.getElementsByTagName("td");
for(var i = 0, j = tds.length; i < j; ++i)
tds[i].style.color = "#00AA00";
