问题描述
我想始终显示前两行,这是我使用.show()完成的。并且还想显示和循环下一行4行,每次2个。
所以4行应该显示在我的表中,前2个是固定的,下2行可以被下两行替换,例如每5秒。
我的jQuery代码
< script type =text / javascript>
$(document).ready(function(){
$('tbody tr:even')。css('background-color','#114c00');
ticker ;
});
function ticker(){
$(tbody tr:#fixed)。show();
$(tbody tr:.hidden)。hide(1000);
}
< / script>
我的HTML
< table id =gradient-stylesummary =Currency>
< thead>
< tr>
< th scope =colclass =flag>< / th>
< / tr>
< / thead>
< tbody>
< tr id =fixed><!---- FIXED ROWS --->

解决方案 var max = 0;
var index = 0;
$ b $(函数(){
$('tbody tr:visible:even')。css('background-color','#114c00');
max = $(tbody tr.hidden)。length;
ticker();
});
函数ticker(){
//用隐藏的类隐藏所有可见的tr
$(tbody tr.hidden:visible)。hide();
var l = index; // low
var h = index + 1; //(高)
$(tbody tr.hidden:hidden)。filter(:eq(+ l +),:eq(+ h +))。
//管理索引
索引+ = 2;
if(index> = max)index = 0;
//重置计时器
setTimeout(ticker(),1000);
}
工作示例:
I want to always show the first two rows, which i have done using .show(). And also want to show and cycle the next 4 rows, 2 at a time.So the 4 rows should show in my table, top 2 are fixed and bottom 2 rows to be replaced by the next two rows, every 5 seconds for example.
My jQuery code
<script type="text/javascript">
$(document).ready(function() {
$('tbody tr:even').css('background-color', '#114c00');
ticker();
});
function ticker(){
$("tbody tr:#fixed").show();
$("tbody tr:.hidden").hide(1000);
}
</script>
My HTML
<table id="gradient-style" summary="Currency">
<thead>
<tr>
<th scope="col" class="flag"></th>
<th scope="col" class="currency"></th>
<th scope="col" class="title"></th>
<th scope="col" class="buy">We Buy</th>
<th scope="col" class="sell">We Sell</th>
</tr>
</thead>
<tbody>
<tr id="fixed"><!----FIXED ROWS--->
<td class="flags"><img src="flags/USD.png" /></td>
<td >USD</td>
<td>US DOLLAR</td>
<td class="value"><span>3.1</span></td>
<td class="value"><span>3.1</span></td>
</tr>
<tr id="fixed"><!----FIXED ROWS---->
<td class="flags"><img src="flags/EUR.png" /></td>
<td>EUR</td>
<td>EURO</td>
<td class="value"><span>5.10</span></td>
<td class="value"><span>3.1</span></td>
</div>
<tr class="hidden"> <!--THIS SHOWS FIRST---->
<td class="flags"><img src="flags/CAD.png" /> </td>
<td>CAD</td>
<td>CANADIAN DOLLAR</td>
<td class="value"><span>8.10</span></td>
<td class="value"><span>3.1</span></td>
</tr>
<tr class="hidden"><!---THIS SHOWS FIRST--->
<td class="flags"><img src="flags/CNY.png" /> </td>
<td>CNY</td>
<td>CHINA YUAN</td>
<td class="value"><span>8.10</span></td>
<td class="value"><span>3.1</span></td>
</tr>
<tr class="hidden"><!---THIS REPLACES THE ROWS ABOVE--->
<td class="flags"><img src="flags/CNY.png" /> </td>
<td>CNY</td>
<td>CHINA YUAN</td>
<td class="value"><span>8.10</span></td>
<td class="value"><span>3.1</span></td>
</tr>
<tr class="hidden"><!---THIS REPLACES THE ROWS ABOVE--->
<td class="flags"><img src="flags/CAD.png" /> </td>
<td>CAD</td>
<td>CANADIAN DOLLAR</td>
<td class="value"><span>8.10</span></td>
<td class="value"><span>3.1</span></td>

});
function ticker() {
// hide all visible tr's with hidden class
$("tbody tr.hidden:visible").hide();
var l = index; // low
var h = index + 1; // high
$("tbody tr.hidden:hidden").filter(":eq(" + l + "), :eq(" + h + ")").show();
// manage index
index += 2;
if (index >= max) index = 0;
// reset timer
setTimeout("ticker()", 1000);
