Question

我有page

按下按钮后，您会看到lib jquery.knob.js的元素（圆圈）我想要改变圆圈大小，我写了这段代码：

<div style="float:left; width:255px; height:155px">
            <input class="knob" data-fgColor="#9dc806" data-cgColor="black" data-bgColor="#7d7d7d" data-tickColor="black" data-thickness=".25" data-readOnly=true value="<?php echo $percent; ?>">
        </div>

但如果我改变div的宽度和高度，圆圈尺寸不会改变？

pb.php的所有代码页：

<?php
header('Content-Type: text/html; charset=utf-8');
include '../connect.php';
include '../ProcessingMySQL.php';
$mysqli = new ProcessingMySQL($hostname, $user_name, $password, $db_name);
$site = $_POST['sites'];
$percent = $mysqli->getPercentTopQuery($site);
?>

<html>
    <head>
    <style type="text/css">
        .knob{color:#000000 !important;}
    </style>

                $(".knob").knob();
                var val,up=0,down=0,i=0
                    ,$idir = $("div.idir")
                    ,$ival = $("div.ival")
                    ,incr = function() { i++; $idir.show().html("+").fadeOut(); $ival.html(i); }
                    ,decr = function() { i--; $idir.show().html("-").fadeOut(); $ival.html(i); };

                                    }
                                );     
                                $('.knob').val($('.knob').val() + '%');

Answer 1

<div style="float:left; width:255px; height:155px">
            <input class="knob" data-fgColor="#9dc806" data-cgColor="black" data-bgColor="#7d7d7d" data-tickColor="black" data-thickness=".25" data-readOnly=true data-width="255" value="<?php echo $percent; ?>">
        </div>

尝试将data-width="width_of_circle"属性添加到input.knob。据我所知，这就是你如何控制圆的宽度。与上面的代码一样（宽度设置为255）

更改lib jquery.knob.js的元素大小
