我正在使用Range Sliders jQuery (picture),如果我没有每次都更改所有值,则表单不会发送,我不知道为什么。如果有人知道如何解决这个问题,即使修改单个值,表单也会发送。谢谢 :))发送设置.php<?phpif(isset($_POST['submit_range'])){ $temp_min_php=$_POST['temp_min_field']; $temp_max_php=$_POST['temp_max_field']; $hum_min_php=$_POST['hum_min_field']; $hum_max_php=$_POST['hum_max_field']; $eau_min_php=$_POST['eau_min_field']; $eau_max_php=$_POST['eau_max_field']; $lum_min_php=$_POST['lum_min_field']; $lum_max_php=$_POST['lum_max_field']; $conn = mysqli_connect("localhost", "root", "toor", "db"); $query = "UPDATE settings SET temp_min = '$temp_min_php',temp_max = '$temp_max_php',hum_min = '$hum_min_php',hum_max = '$hum_max_php',eau_min = '$eau_min_php',eau_max = '$eau_max_php',lum_min = '$lum_min_php',lum_max = '$lum_max_php'"; $result = mysqli_query($conn, $query);}?>设置.php <script type="text/javascript"> $(function() { $( "#temp-range" ).slider({ range: true, min: 0, max: 500, values: [ <?php echo $row['temp_min']; ?>, <?php echo $row['temp_max']; ?> ], slide: function( event, ui ) { $( "#temp_amount" ).html( ui.values[ 0 ]+ " °C" + " - " + ui.values[ 1 ]+ " °C" ); $( "#temp_min_field" ).val(ui.values[ 0 ]); $( "#temp_max_field" ).val(ui.values[ 1 ]); } }); $( "#temp_amount" ).html( $( "#temp-range" ).slider( "values", 0 )+ " °C" + " - " + $( "#temp-range" ).slider( "values", 1 )+ " °C" ); });

隐藏输入的“值”属性仅在移动滑块时设置。您需要在此处设置初始值:
<input type="hidden" id="temp_min_field" name="temp_min_field">
<input type="hidden" id="temp_max_field" name="temp_max_field">
像这样:
<input type="hidden" id="temp_min_field" name="temp_min_field" value="<?php echo $row['temp_min']; ?>">
<input type="hidden" id="temp_max_field" name="temp_max_field" value="<?php echo $row['temp_max']; ?>">
