Question

我现在正在Dropdownlist分页中工作。但问题是我不知道下一步我要做什么。

这是脚本。下拉列表值是正确的，但我不知道如何完成此脚本。我需要的是当我选择分页下拉列表时，它会显示基于itemperpage的记录。但是这个脚本无效。

$('#pageNo').on('change', function(){
    var loadPage = $('#pageNo').val();
    // Do your page submit to load another page
});

get.php

<?php
$mysqli = new mysqli("localhost", "root", "", "app");

$id = $mysqli->real_escape_string($_GET["q"]);//used for Dynamic Dropdown  

$id2 = $mysqli->real_escape_string($_GET["id"]); // used for PHP pagination

$sql = $mysqli->query("SELECT * FROM app ORDER BY id ASC");  
$nr = mysqli_num_rows($sql); 

$itemsPerPage = 100; 

$page_count = ($nr / $itemsPerPage) + 1;

echo"<select id='pageNo'>";
        for($y=1; $y < $page_count; $y++) {
            echo "<option value='".$y."'>".$y."</option>";
        }
echo'</select>';
?>

Select.php

<script>
function showUser(str,ids) {
    var $txtHint = $('#txtHint');
    if (str=="" || ids=="") {
        $txtHint.html('');
        return;
    }
    $txtHint.load('get.php?q='+str+'&id='+ids)  
}

</script>
<body onload=showUser(str="ALL")>

<select name="drop_1" id="drop_1" onchange="showUser(this.value)" style="overflow:scroll;width:100px;">
        <option value="ALL" selected='ALL'>ALL</option>
        <?php getTierOne(); ?>
</select>
<div id="txtHint"></div>

Answer 1

在你的SQL中可能更容易做到

 $sql = $mysqli->query("SELECT * FROM app ORDER BY id ASC LIMIT ".$pagenum*100.",100");

下拉选择分页页面
