使用鼠标改变元素的尺寸。

如需了解更多有关 resizable 交互的细节,请查看 API 文档 可调整尺寸小部件(Resizable Widget)

默认功能

在任意的 DOM 元素上启用 resizable 功能。通过鼠标拖拽右边或底边的边框到所需的宽度或高度。

<!doctype html><html lang="en"><head>  <meta charset="utf-8">  <title>jQuery UI 缩放(Resizable) - 默认功能</title>  <link rel="stylesheet" href="https://zhishitu.com/">  <script src="/images/2021/06/11/202106110417332773780.js"></script>  <script src="/images/2021/06/11/202106110417332776471.js"></script>  <link rel="stylesheet" href="https://zhishitu.com/">  <style>  #resizable { width: 150px; height: 150px; padding: 0.5em; }  #resizable h3 { text-align: center; margin: 0; }  </style>  <script>  $(function() {    $( "#resizable" ).resizable();  });  </script></head><body> <div id="resizable" class="ui-widget-content">  <h3 class="ui-widget-header">缩放(Resizable)</h3></div>  </body></html>

动画

使用 animate 选项(布尔值)使缩放行为动画化。当该选项设置为 true 时,拖拽轮廓到所需的位置,元素会在拖拽停止时以动画形式调整到该尺寸。

<!doctype html><html lang="en"><head>  <meta charset="utf-8">  <title>jQuery UI 缩放(Resizable) - 动画</title>  <link rel="stylesheet" href="https://zhishitu.com/">  <script src="/images/2021/06/11/202106110417332773780.js"></script>  <script src="/images/2021/06/11/202106110417332776471.js"></script>  <link rel="stylesheet" href="https://zhishitu.com/">  <style>  #resizable { width: 150px; height: 150px; padding: 0.5em; }  #resizable h3 { text-align: center; margin: 0; }  .ui-resizable-helper { border: 1px dotted gray; }  </style>  <script>  $(function() {    $( "#resizable" ).resizable({      animate: true    });  });  </script></head><body> <div id="resizable" class="ui-widget-content">  <h3 class="ui-widget-header">动画</h3></div>  </body></html>

限制缩放区域

定义缩放区域的边界。使用 containment 选项来指定一个父级的 DOM 元素或一个 jQuery 选择器,比如 'document.'。

<!doctype html><html lang="en"><head>  <meta charset="utf-8">  <title>jQuery UI 缩放(Resizable) - 限制缩放区域</title>  <link rel="stylesheet" href="https://zhishitu.com/">  <script src="/images/2021/06/11/202106110417332773780.js"></script>  <script src="/images/2021/06/11/202106110417332776471.js"></script>  <link rel="stylesheet" href="https://zhishitu.com/">  <style>  #container { width: 300px; height: 300px; }  #container h3 { text-align: center; margin: 0; margin-bottom: 10px; }  #resizable { background-position: top left; width: 150px; height: 150px; }  #resizable, #container { padding: 0.5em; }  </style>  <script>  $(function() {    $( "#resizable" ).resizable({      containment: "#container"    });  });  </script></head><body> <div id="container" class="ui-widget-content">  <h3 class="ui-widget-header">限制</h3>  <div id="resizable" class="ui-state-active">    <h3 class="ui-widget-header">缩放(Resizable)</h3>  </div></div>  </body></html>

延迟开始

通过 delay 选项设置延迟开始缩放的毫秒数。通过 distance 选项设置光标被按下且拖拽指定像素后才允许缩放。

<!doctype html><html lang="en"><head>  <meta charset="utf-8">  <title>jQuery UI 缩放(Resizable) - 延迟开始</title>  <link rel="stylesheet" href="https://zhishitu.com/">  <script src="/images/2021/06/11/202106110417332773780.js"></script>  <script src="/images/2021/06/11/202106110417332776471.js"></script>  <link rel="stylesheet" href="https://zhishitu.com/">  <style>  #resizable, #resizable2 { width: 150px; height: 150px; padding: 0.5em; }  #resizable h3, #resizable2 h3 { text-align: center; margin: 0; }  </style>  <script>  $(function() {    $( "#resizable" ).resizable({      delay: 1000    });     $( "#resizable2" ).resizable({      distance: 40    });  });  </script></head><body> <h3 class="docs">时间延迟 (ms):</h3><div id="resizable" class="ui-widget-content">  <h3 class="ui-widget-header">时间</h3></div> <h3 class="docs">距离延迟 (px):</h3><div id="resizable2" class="ui-widget-content">  <h3 class="ui-widget-header">距离</h3></div>  </body></html>

助手

通过设置 helper 选项为一个 CSS class,当缩放时只显示元素的轮廓。

<!doctype html><html lang="en"><head>  <meta charset="utf-8">  <title>jQuery UI 缩放(Resizable) - 助手</title>  <link rel="stylesheet" href="https://zhishitu.com/">  <script src="/images/2021/06/11/202106110417332773780.js"></script>  <script src="/images/2021/06/11/202106110417332776471.js"></script>  <link rel="stylesheet" href="https://zhishitu.com/">  <style>  #resizable { width: 150px; height: 150px; padding: 0.5em; }  #resizable h3 { text-align: center; margin: 0; }  .ui-resizable-helper { border: 2px dotted #00F; }  </style>  <script>  $(function() {    $( "#resizable" ).resizable({      helper: "ui-resizable-helper"    });  });  </script></head><body> <div id="resizable" class="ui-widget-content">  <h3 class="ui-widget-header">助手</h3></div>  </body></html>

最大/最小尺寸

使用 maxHeightmaxWidthminHeightminWidth 选项限制 resizable 元素的最大或最小高度或宽度。

<!doctype html><html lang="en"><head>  <meta charset="utf-8">  <title>jQuery UI 缩放(Resizable) - 最大/最小尺寸</title>  <link rel="stylesheet" href="https://zhishitu.com/">  <script src="/images/2021/06/11/202106110417332773780.js"></script>  <script src="/images/2021/06/11/202106110417332776471.js"></script>  <link rel="stylesheet" href="https://zhishitu.com/">  <style>  #resizable { width: 200px; height: 150px; padding: 5px; }  #resizable h3 { text-align: center; margin: 0; }  </style>  <script>  $(function() {    $( "#resizable" ).resizable({      maxHeight: 250,      maxWidth: 350,      minHeight: 150,      minWidth: 200    });  });  </script></head><body> <div id="resizable" class="ui-widget-content">  <h3 class="ui-widget-header">放大/缩小</h3></div>  </body></html>

保持纵横比

保持现有的纵横比或设置一个新的纵横比来限制缩放比例。设置 aspectRatio 选项为 true,且可选地传递一个新的比率(比如,4/3)。

<!doctype html><html lang="en"><head>  <meta charset="utf-8">  <title>jQuery UI 缩放(Resizable) - 保持纵横比</title>  <link rel="stylesheet" href="https://zhishitu.com/">  <script src="/images/2021/06/11/202106110417332773780.js"></script>  <script src="/images/2021/06/11/202106110417332776471.js"></script>  <link rel="stylesheet" href="https://zhishitu.com/">  <style>  #resizable { width: 160px; height: 90px; padding: 0.5em; }  #resizable h3 { text-align: center; margin: 0; }  </style>  <script>  $(function() {    $( "#resizable" ).resizable({      aspectRatio: 16 / 9    });  });  </script></head><body> <div id="resizable" class="ui-widget-content">  <h3 class="ui-widget-header">保持纵横比</h3></div>  </body></html>

对齐到网格

对齐 resizable 元素到网格。通过 grid 选项设置网格单元的尺寸(以像素为单位的高度和宽度)。

<!doctype html><html lang="en"><head>  <meta charset="utf-8">  <title>jQuery UI 缩放(Resizable) - 对齐到网格</title>  <link rel="stylesheet" href="https://zhishitu.com/">  <script src="/images/2021/06/11/202106110417332773780.js"></script>  <script src="/images/2021/06/11/202106110417332776471.js"></script>  <link rel="stylesheet" href="https://zhishitu.com/">  <style>  #resizable { width: 150px; height: 150px; padding: 0.5em; }  #resizable h3 { text-align: center; margin: 0; }  </style>  <script>  $(function() {    $( "#resizable" ).resizable({      grid: 50    });  });  </script></head><body> <div id="resizable" class="ui-widget-content">  <h3 class="ui-widget-header">网格</h3></div>  </body></html>

同步缩放

通过点击并拖拽一个元素的边来同时调整多个元素的尺寸。给 alsoResize 选项传递一个共享的选择器。

<!doctype html><html lang="en"><head>  <meta charset="utf-8">  <title>jQuery UI 缩放(Resizable) - 同步缩放</title>  <link rel="stylesheet" href="https://zhishitu.com/">  <script src="/images/2021/06/11/202106110417332773780.js"></script>  <script src="/images/2021/06/11/202106110417332776471.js"></script>  <link rel="stylesheet" href="https://zhishitu.com/">  <style>  #resizable { background-position: top left; }  #resizable, #also { width: 150px; height: 120px; padding: 0.5em; }  #resizable h3, #also h3 { text-align: center; margin: 0; }  #also { margin-top: 1em; }  </style>  <script>  $(function() {    $( "#resizable" ).resizable({      alsoResize: "#also"    });    $( "#also" ).resizable();  });  </script></head><body> <div id="resizable" class="ui-widget-header">  <h3 class="ui-state-active">缩放</h3></div> <div id="also" class="ui-widget-content">  <h3 class="ui-widget-header">同步缩放</h3></div>  </body></html>

文本框

可缩放的文本框。

<!doctype html><html lang="en"><head>  <meta charset="utf-8">  <title>jQuery UI 缩放(Resizable) - 文本框</title>  <link rel="stylesheet" href="https://zhishitu.com/">  <script src="/images/2021/06/11/202106110417332773780.js"></script>  <script src="/images/2021/06/11/202106110417332776471.js"></script>  <link rel="stylesheet" href="https://zhishitu.com/">  <style>  .ui-resizable-se {    bottom: 17px;  }  </style>  <script>  $(function() {    $( "#resizable" ).resizable({      handles: "se"    });  });  </script></head><body> <textarea id="resizable" rows="5" cols="20"></textarea>  </body></html>

视觉反馈

通过设置 ghost 选项为 true,可在缩放期间显示一个半透明的元素,而不是显示一个实际的元素。

<!doctype html><html lang="en"><head>  <meta charset="utf-8">  <title>jQuery UI 缩放(Resizable) - 视觉反馈</title>  <link rel="stylesheet" href="https://zhishitu.com/">  <script src="/images/2021/06/11/202106110417332773780.js"></script>  <script src="/images/2021/06/11/202106110417332776471.js"></script>  <link rel="stylesheet" href="https://zhishitu.com/">  <style>  #resizable { width: 150px; height: 150px; padding: 0.5em; }  #resizable h3 { text-align: center; margin: 0; }  .ui-resizable-ghost { border: 1px dotted gray; }  </style>  <script>  $(function() {    $( "#resizable" ).resizable({      ghost: true    });  });  </script></head><body> <div id="resizable" class="ui-widget-content">  <h3 class="ui-widget-header">Ghost</h3></div>  </body></html>
