HTML 表的 PHP 類(lèi)別：奇怪的屬性分配

<p>在建立 HTML 表格的類(lèi)別中，我有這個(gè)呈現(xiàn)表格的方法。除了某些條件下的 HTML 屬性分配之外，一切都正常運(yùn)作（縮排、結(jié)束標(biāo)籤、資料表示等）。當(dāng)我設(shè)定單元格資料時(shí)，我會(huì)呼叫 setData() 來(lái)接收三個(gè)參數(shù)並像這樣使用它。注意我如何設(shè)定第三個(gè)參數(shù)（單元格屬性）：</p>
<p><strong>方法定義：</strong></p>
<pre class="brush:php;toolbar:false;">public function setData(
array $data,
array $row_attributes = [],
array $cell_attributes = []
): bool {
// the code
}</pre>
<p><strong>通話(huà)：</strong></p>
<pre class="brush:php;toolbar:false;">$table->setData(
$pagination->resultset,
[], // row attributes
array( // cell attributes
array(), // row 1 (index 0)
array( // row2 (index 1)
["id"=>"R2C1id"], // row 2, cell 1
["id"=>"R2C2id", "onclick"=>"R2C2_onclick();"], // row 2, cell 2
),
array( // row 3
[],
[],
["id"=>"R3C3id", "selected"=>"selected"], // row 3, cell 3
[],
[],
[],
[]
)
)
);</pre>
<p>在此範(fàn)例中，表格有七個(gè)欄位。 </p>
<p>在這裡您將看到 HTML 輸出。注意第二行和第三行的單元格屬性：</p>
<pre class="brush:php;toolbar:false;"><div class='table-body'>
<div class='table-row'>
<div class='table-row-cell'>1</div>
<div class='table-row-cell'>Consumidor Final</div>
<div class='table-row-cell'>Consumidor Final</div>
<div class='table-row-cell'></div>
<div class='table-row-cell'>1</div>
<div class='table-row-cell'></div>
<div class='table-row-cell'></div>
</div>
<div class='table-row'>
<div class='table-row-cell' id='R2C1id'>2</div>
<div class='table-row-cell' id='R2C2id' onclick='R2C2_onclick();'>Prueba SRL</div>
<div class='table-row-cell' 0='Array' 1='Array'>Tu Prueba</div>
<div class='table-row-cell' 0='Array' 1='Array'>12345678901</div>
<div class='table-row-cell' 0='Array' 1='Array'>1</div>
<div class='table-row-cell' 0='Array' 1='Array'></div>
<div class='table-row-cell' 0='Array' 1='Array'></div>
</div>
<div class='table-row'>
<div class='table-row-cell'>3</div>
<div class='table-row-cell'>Otra Prueba SA</div>
<div class='table-row-cell' id='R3C3id' selected='selected'>Prueba 2</div>
<div class='table-row-cell'>12345678902</div>
<div class='table-row-cell'>1</div>
<div class='table-row-cell'></div>
<div class='table-row-cell'></div>
</div>
</div></pre>
<p>這是我用來(lái)完成這一切的程式碼。我將向您展示單元格渲染的程式碼片段以及處理屬性的方法。 </p>
<p><strong>儲(chǔ)存格渲染：</strong></p>
<pre class="brush:php;toolbar:false;">// process cells
$row_counter = 0;
foreach ($this->data as $data) { // row
$row_build = "";
$cell_counter = 0;
foreach ($data as $cell_data) { // cell
if ($cell_counter < $col_count) {
$row_build .= $this->getHtmlDiv(
$html_cell_class,
$cell_data ?? "",
$this->getHtmlAttributes("cell", $row_counter, $cell_counter),
3
);
}
$cell_counter ;
}
// $cell_counter ;
// complete empty cells to preserve row:hover on full row
while ($cell_counter < $col_count) {
$row_build .= $this->getHtmlDiv(
$html_cell_class,
"",
$this->getHtmlAttributes("cell", $row_counter, $cell_counter),
3
);
$cell_counter ;
}
$body_build .= $this->getHtmlDiv(
$html_row_class,
$row_build,
$this->getHtmlAttributes("row", $row_counter, 0),
2,
true
);
$row_counter ;
}</pre>
<p><strong>屬性的方法：</strong></p>
<pre class="brush:php;toolbar:false;">private function getHtmlAttributes(string $section, int $row, int $column): array
{
if (count($this->html_attributes[$section]) > 0) {
if (array_key_exists($row, $this->html_attributes[$section])) {
if ($section === "cell") {
if (array_key_exists($column, $this->html_attributes[$section][$row])) {
return $this->html_attributes[$section][$row][$column];
}
}
return $this->html_attributes[$section][$row];
}
}
return [];
}</pre>
<p>怎麼了？謝謝。 </p>
