jQuery-ui resizable:调整大小不适用于动态创建的SVG元素 [英] jQuery-ui resizable: Resizing doesn't work for dynamically created SVG element
问题描述
我在<div>内有一个SVG <rect>，想要拖动并调整其大小.当我像这样在HTML中静态创建元素时:
I have an SVG <rect> inside a <div> and want to drag and resize it. When I create the elements statically in the HTML like so:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.18/themes/start/jquery-ui.css">
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.18/jquery-ui.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('div').draggable({
handle: 'rect'
}).resizable({
aspectRatio: 1.0
});
});
</script>
</head>
<body>
<div style="width:400px; height:400px; border:solid thin #888; padding:10px; border-radius:4px; background-color:#ccc;">
<svg xmlns="http://www.w3.org/2000/svg" version="1.0" viewBox="0 0 400 400">
<rect x="0" y="0" width="200" height="200" style="fill:#FF0000" />
</svg>
</div>
</body>
一切正常. <rect>与<div>一起拖动并调整大小，但是当我像这样动态生成元素时:
everything works. The <rect> is dragged and resized together with the <div>, but when I generate the elements dynamically like so:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.18/themes/start/jquery-ui.css">
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.18/jquery-ui.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('body').append('<div style="width:400px; height:400px; border:solid thin #888; padding:10px; border-radius:4px; background-color:#ccc;">');
var svg = document.createElementNS('http://www.w3.org/2000/svg', "svg");
svg.setAttributeNS(null, "viewbox", "0 0 400 400");
$('div').append(svg);
var square = document.createElementNS('http://www.w3.org/2000/svg', "rect");
square.setAttributeNS(null, "width", "200");
square.setAttributeNS(null, "height", "200");
square.setAttributeNS(null, "x", "0");
square.setAttributeNS(null, "y", "0");
square.setAttributeNS(null, "style", "fill:#FF0000");
$('svg').append(square);
$('div').draggable({
handle: 'rect'
}).resizable({
aspectRatio: 1.0
});
});
</script>
</head>
<body>
</body>
</html>
仅拖动对于<div>和<rect>均继续起作用.调整大小仅适用于<div>，<rect>完全不改变大小.
only dragging continues to work for both the <div> and the <rect>. Resizing works only for the <div>, the <rect> doesn't change size at all.
怎么了?
推荐答案
在使用正确的"viewBox"大小写的静态情况下，SVG区分大小写.在动态情况下则不需要.
SVG is case sensitive in the static case you use the correct "viewBox" case. In the dynamic case you don't.
svg.setAttributeNS(null, "viewbox", "0 0 400 400");
应该是
svg.setAttributeNS(null, "viewBox", "0 0 400 400");
