我目前有许多函数将信息添加到表中(示例所示):
function Applyd()
{
foreach($_POST['select3'] as $project1)
{
$project = $_POST['select3'];
// Set $fromdate to the entered value if there was one, otherwise set it to something long ago
$fromdate = $_REQUEST["from"] ? $_REQUEST["from"] : date("Y-m-d", strtotime("-100 years"));
// Set $todate to the entered value if there was one, otherwise set it to tomorrow. There shouldn't be any finished dates in the future!
$todate = $_REQUEST["to"] ? $_REQUEST["to"]: date("Y-m-d", strtotime("+1 day"));
// Remove the hyphens so that our dates are in the same format as the text file and we can compare them directly
$fromdate = str_replace("-", "", $fromdate);
$todate = str_replace("-", "", $todate);
$handle = @fopen("project-list.txt", "r");
while(!feof($handle)) {
$row = fgets($handle);
$col1 = explode ("'t", $row);
if(($col1[0] !== "unfinished") && ($col1[0] >= $fromdate) && ($col1[0] <= $todate) && strpos($row, $project1) !== FALSE)
{
// Or save the $row in an array to write out later
echo "<table id='example'>";
echo "<table border='"5'" cellpadding='"10'">";
echo "<tr>";
echo $row . "<br />";
}
echo "</tr>";
echo "</table>";
}
fclose($handle);
}
}
function Applydd()
{
// Set $fromdate to the entered value if there was one, otherwise set it to something long ago
$fromdate = $_REQUEST["from"] ? $_REQUEST["from"] : date("Y-m-d", strtotime("-100 years"));
// Set $todate to the entered value if there was one, otherwise set it to tomorrow. There shouldn't be any finished dates in the future!
$todate = $_REQUEST["to"] ? $_REQUEST["to"]: date("Y-m-d", strtotime("+1 day"));
// Remove the hyphens so that our dates are in the same format as the text file and we can compare them directly
$fromdate = str_replace("-", "", $fromdate);
$todate = str_replace("-", "", $todate);
$handle = @fopen("project-list.txt", "r");
while(!feof($handle)) {
$row = fgets($handle);
$col1 = explode ("'t", $row);
if(($col1[0] !== "unfinished") && ($col1[0] >= $fromdate) && ($col1[0] <= $todate))
{
// Or save the $row in an array to write out later
echo "<table id='example'>";
echo "<table border='"5'" cellpadding='"10'">";
echo "<tr>";
echo $row . "<br />";
}
echo "</tr>";
echo "</table>";
}
fclose($handle);
}
我希望用户能够在表中搜索关键字。我试过使用这个,但它不显示任何结果。我不知道我做错了什么。
<script src ="https://cdn.datatables.net/1.10.7/js/jquery.dataTables.min.js"></script>
<script>
function myFunction(){
var table = $('#example').DataTable();
// #myInput is a <input type="text"> element
$('#search').on( 'keyup', function () {
table.search( this.value ).draw();
} );
}
</script>
生成的表不正确,请参阅其中一个表的更正代码。
还要确保您指定的<thead>
具有与列数相对应的<th></th>
元素的正确数量。
echo '<table id="example" border="5" cellpadding="10">';
echo '<thead><tr><th>Col1</th><th>Col2</th><th>Col3</th></tr></thead>';
echo '<tbody>';
while(!feof($handle)) {
$row = fgets($handle);
$col1 = explode("'t", $row);
if(($col1[0] !== "unfinished") && ($col1[0] >= $fromdate) && ($col1[0] <= $todate))
{
echo '<tr><td>';
echo implode('</td><td>', htmlspecialchars($row));
echo '</td></tr>';
}
}
echo '</tbody>';
echo '</table>';
也不需要使用单独的搜索框和额外的编码,因为jQuery DataTables默认提供了搜索框,参见Zero配置示例。
