问题描述
只要简单地加载(打开)页面,我就可以使用SVGweb.
I have no problem using SVGweb when page is simply loaded (opened).
如何重新初始化SVGweb以便在页面上重新绘制所有SVG?
How is it possible to reinitialize SVGweb in order to redraw all SVG on the page?
换句话说,我需要SVGweb重新扫描并重新呈现页面上的所有内容.
Anotherwords I need SVGweb to rescan and rerender everything on the page.
来源(来自此):
<script type="image/svg+xml">
<svg>
...
</svg>
</script>
对此(就像SVGweb si只是在打开页面时所做的那样):
to this (like SVGweb si doing that when simply open the page):
<svg>
...
</svg>
我需要这个,因为我使用ajax更改了SVG图形,并且需要在页面上重新呈现它.
I need this because I change the SVG graphics using ajax and need to rerender it on the page.
推荐答案
使用新的SVGweb代码(通过Ajax)更改DOM后
After the DOM is changed with a new SVGweb code (through Ajax)
<script type="image/svg+xml">
<svg>
...
</svg>
</script>
需要执行以下操作: svgweb._onDOMContentLoaded();
need to execute this: svgweb._onDOMContentLoaded();
但是在注释SVGweb svg-uncompressed.js或svg.js的核心源代码中的一行之前,
But before need to comment a line in the core source of SVGweb svg-uncompressed.js or svg.js
svg-uncompressed.js来自
svg-uncompressed.jsfrom
if (arguments.callee.done) {
return;
}
到
if (arguments.callee.done) {
//return;
}
svg.js:查找并删除它:
svg.js: find and delete this:
arguments.callee.done=true;
或替换为
arguments.callee.done=false;
编辑:
另一个适用于IE9的修复程序:
One more fix to work for IE9:
对于svg.js
来自
var a=document.getElementById("__ie__svg__onload");if(a){a.parentNode.removeChild(a);a.onreadystatechange=null}
到
var IEv=parseFloat(navigator.appVersion.split("MSIE")[1]);if(IEv<9){var a=document.getElementById("__ie__svg__onload");if(a){a.parentNode.removeChild(a);a.onreadystatechange=null;a=null;}}
对于svg-uncompressed.js
for svg-uncompressed.js
来自
// cleanup onDOMContentLoaded handler to prevent memory leaks on IE
var listener = document.getElementById('__ie__svg__onload');
if (listener) {
listener.parentNode.removeChild(listener);
listener.onreadystatechange = null;
listener = null;
}
到
// cleanup onDOMContentLoaded handler to prevent memory leaks on IE
var IEv=parseFloat(navigator.appVersion.split("MSIE")[1]);
if (IEv<9) {
var listener = document.getElementById('__ie__svg__onload');
if (listener) {
listener.parentNode.removeChild(listener);
listener.onreadystatechange = null;
listener = null;
}
}
