[英]how can i highlight a row when date is older than yesterday
我對jQuery和JavaScript非常陌生。 我有一個小問題。 假設我有一個如下的HTML表格
<?php
include 'dbconnect.php';
$sql = "SELECT * FROM Comments";
$result = mysqli_query($conn,$sql);
if (!$result) {
echo '<div>no comments were set up</div>';
}
$fields_num = mysqli_num_fields($result);
echo "<h1>Table: {$table}</h1>";
echo "<table id='myTable' border='1'><tr>";
// printing table headers
for($i=0; $i<$fields_num; $i++)
{
$field = mysqli_fetch_field($result);
echo "<td>{$field->name}</td>";
}
echo "</tr>\n";
// printing table rows
while($row = mysqli_fetch_row($result))
{
echo "<tr>";
// $row is array... foreach( .. ) puts every element
// of $row to $cell variable
foreach($row as $cell)
echo "<td>$cell</td>";
//delete button
echo "<td><input type='button' value='Delete' onclick='deleteRow(this)'></td>";
//checkbox button
echo "<td><input type='checkbox' value='Highlight' onclick='highlight(this)'></td>";
echo "</tr>\n";
}
mysqli_free_result($result);
?>
我想檢查第8列中的日期是否早於應突出顯示該行的日期。 我該如何進行。
我找到了一個代碼,但是沒有用:
function checkdate(){
$('#myTable tr td').each(function () {
var dtTd = new Date($(this).html());
var dtNew = new Date();
// 15 minutes is 900000 milliseconds
// getTime() doc - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/getTime
if (dtTd.getTime() - dtNew.getTime() < 900000 && dtNew < dtTd) {
$(this).css("background-color", "red");
} else {
if (dtNew > dtTd) {
$(this).css("background-color", "yellow");
}
}
});
}
嘗試這個:
$date = date('Y-m-d');
foreach($row as $cell)
{
if($cell['date'] < $date)
{
// for date less then today's date
}
else
{
// for others date
}
}
