我需要有关此代码的帮助..
这是表格:
<table id="tabela_zaduzi_plombe" class="table-responsive table table-striped table-bordered table-hover dataTable no-footer font-size-13">
<thead>
<tr class="boja-reda">
<th class="width-50"></th>
<th class="align-center width-50"><input type="checkbox" id="checkAll" /></th>
<th class="width-300"><?php echo __("SERIJSKI BROJ"); ?></th>
</tr>
</thead>
<tbody>
<?php //debug($lista_slobodnih_plombi); die; ?>
<?php foreach($lista_slobodnih_plombi as $lista_sp): ?>
<?php foreach($lista_sp as $lista): ?>
<tr>
<td></td>
<td class="align-center td_checkbox"><input type="checkbox" name="link-cbx" class="checkItem" autocomplete="on" id="<?php echo $lista;?>" data-sb_plombe="<?php echo $lista;?>"/></td>
<td class="sbr"><?php echo $lista;?></td>
</tr>
<?php endforeach; ?>
<?php endforeach; ?>
</tbody>
</table>
这是数组的输出:
array(
(int) 0 => array(
(int) 0 => '222222222',
(int) 1 => '222222223',
(int) 2 => '222222224',
(int) 3 => '222222225'
),
(int) 1 => array(
(int) 0 => '333333333',
(int) 1 => '333333334'
),
(int) 2 => array(
(int) 0 => '444444444',
(int) 1 => '444444445',
(int) 2 => '444444446',
(int) 3 => '444444447',
(int) 4 => '444444448'
)
)
我需要更改背景颜色,以便数组的每个成员都有自己的颜色。
示例:如果我有3个阵列,我需要3种不同的颜色。 谢谢!

在向td添加背景颜色之前,需要为每个数组键生成随机颜色。这是使用键和值(颜色代码)
创建颜色数组的功能function getColors($array) {
// init array
$colors = array();
// count of number of random colors to generate
if(count($array)>0){
// get the keys of passed array ( will be help full if the passed array is associative array )
$array_keys = array_keys($array);
$chars = "ABCDEF0123456789";
$size = strlen($chars);
foreach($array_keys as $value){
for( $j = 0; $j < 6; $j++ ) {
// generate a random color for each key of passed array
$colors[$value] .= $chars[ rand( 0, $size - 1 ) ];
}
}
}
return $colors;
}
现在为td添加bgcolor。
<?php
// call the function to get random colors
$colors = getColors($lista_slobodnih_plombi);?>
<?php foreach($lista_slobodnih_plombi as $key=>$lista_sp): ?>
<?php foreach($lista_sp as $lista):
?>
<tr>
<td></td>
<td class="align-center td_checkbox"><input type="checkbox" name="link-cbx" class="checkItem" autocomplete="on" id="<?php echo $lista;?>" data-sb_plombe="<?php echo $lista;?>"/></td>
<td class="sbr" bgcolor="<?php echo '#'.$colors[$key];?>"><?php echo $lista;?></td>
</tr>
<?php endforeach; ?>
<?php endforeach; ?>
注意:每次加载页面时背景颜色都会发生变化。
