• 把.html转换成.jsp中jqplot画图表不能正常显示,出错的心得


    在做这个的时候,明明html中是完全可行的,如下图:

    但后缀名改成.jsp后竟出现如下情况:

    这太坑爹了吧,我的图呢!

    哎,又要自己找代码问题了,无奈!

    先给出我还没修改前的代码吧,关于里面的.js,.css的,自己下个jqplot,里面都有,你们自己解决吧,哈哈

    经过整个上午的努力,得到了一个简单的解决方案,如下所示嘿:

    其实很简单啦 ,就是把

     <base href="<%=basePath%>"> 
    这句给删了,然后再加上<script type="text/javascript" src="js/excanvas.js"></script>这句,关于excanvas.js上网随便下个,好像jqplot里面也有。然后再把后缀改成.jsp,哈,完美运行中............
