Jquery Jqplot的IE8打印问题
我正在用IE8测试jqplot。当我试图打印时，轴标签偏移了。我用安德鲁·布洛克的拉票技巧作为解决办法。（）它仍然没有解决这个问题。我不熟悉脚本编写。我的代码有什么问题吗？请帮忙 谢谢， 蜀Jquery Jqplot的IE8打印问题,jquery,printing,internet-explorer-8,jqplot,Jquery,Printing,Internet Explorer 8,Jqplot,我正在用IE8测试jqplot。当我试图打印时，轴标签偏移了。我用安德鲁·布洛克的拉票技巧作为解决办法。（）它仍然没有解决这个问题。我不熟悉脚本编写。我的代码有什么问题吗？请帮忙 谢谢， 蜀 （函数（$）{ $.fn.CanvasHack=函数（）{ var canvases=this.find（'canvas'）.filter（函数（）{ 返回$（this.css（'position'）='absolute'； }); canvases.wrap（函数（）{ var canvas=$（此值）

修复这些和你的歌唱：）安德鲁提供的解决方案对我不起作用。相反，我不得不修改excanvac.js，注释掉以下几行：
//var overlayEl = el.cloneNode(false);
// Use a non transparent background.
//overlayEl.style.backgroundColor = 'red';
//overlayEl.style.filter = 'alpha(opacity=0)';
//canvasElement.appendChild(overlayEl);
希望这能帮助一些人，这样他们就不必经历试图弄明白这一点的痛苦过程。这个答案对我来说非常有用！我必须将excanvas.js代码更改和发布问题的地方的代码结合起来。我将在下面发布我的源代码，它在IE7中正确使用了JQPlot和函数。这是在SharePoint中托管的，因此是包含CAML查询的SOAP信封 以下是基本布局：
- 含函数图
- 调用canvas fix
- 包含图的函数的结束
