canvas函数图
【初始编辑】2013/4/21 14:55
【更新 2013/5/1 14:36 】
更新日志：加上坐标轴的箭头，加了两个函数(其实这个不算更新吧。。)。
优化了一下绘制方法：修改了清除画布的方法，极大提高效率。
自定义函数的功能还是没有修好。
代码中已经包含了一部分下次更新的功能：差不多是坐标轴的单位线
昨天我翻出来了以前一时兴起做的一个渣渣函数图绘制的代码，然后又一时兴起想把它改好一点，于是就出现了今天的这篇文章。
【我可是冒着期中考试前不复习的风险来做这个的】
【用chrome浏览效果更佳，其他浏览器可能会有卡顿现象】
现在已经做成了这个样子

iframe元素操作
本文所有内容均未测试，只是看着参考写出来的笔记，不保证内容的准确性，如果发现了错误请指出谢谢。
在很久很久以前(其实是忘了时间。。。)我发现iframe内部的内容是可以在iframe外面操作的。
在这之前我曾经把Glory的blog做了iframe放在我的佳佳实验室里，然后他一脸黑线，现在我终于知道是为什么了~
接下来进入正文
访问iframe元素的关键就在于要知道连接到iframe的方法，看下面
[PS：不同方法在不同浏览器里可能不可用]
图片转data:URI工具
昨晚由于需要用data:uri，于是做了这么个转换工具
可本地使用，因为文件不用上传
疯狂的点击这里看demo
截图[此截图使用datauri,看不见请升级人品]

datauri优点：
在页面添加图片不用额外上传文件了！
还有什么就不知到了
缺点：
无法缓存，每次加载页面都要载入（其实想缓存它只要用js文件复制给变量就行了，而且可以一个文件存N张图，和图片分割异曲同工啊）
浏览器支持不全面
转出来的字符串体积一般比原文件大= =。。。
demo源码[部分参考其他网站]
把图片拖到这里
[其实我发现除了图片以外还可以拖其它任何文件进来，只不过下面的预览图会裂掉另外最好不要把超过1MB的文件拉进来，不然你懂的]
PS:如果同时拖入多个文件，只操作第一个，拖入文件夹无效
视频手动载入js
俺花了好长时间，用我这不熟练的技术好不容易做了个带满缺点的js
那么这货的用处就是屏蔽掉flash这样的东西【当然如果修改一下js可以屏蔽掉body里的任何标签
先来个示例【有视频有真相
embed标签的例子（无视频源）video标签的例子(同上)
object标签的例子(同上)
其实屏蔽了以后看起来都是一样的。。
这货的功能：点击以后再载入，防止意外流量损失或带宽？占用
这就是个鲜明的例子http://blog.luojia.tk/?p=181
里面装满了视频，这样就可以解决打开这个网页一下载入很多视频的问题了
原理：让div插队再干掉背后的原标签并给这个div添加可以给自己内部写入被杀掉标签的事件↓
|
1 2 3 4 |
objarray[i].parentNode.insertBefore(tmpdiv,objarray[i]);//插队到原标签前面 objarray[i].parentNode.removeChild(objarray[i]);//干掉原标签 |
特点：插队的div使用源元素的宽高和定位【本来想把z-index也算进去的，时间不够就不做了↓
|
1 2 3 4 5 6 7 8 |
//一堆if用来判断是否有这些属性 if(getwidth(objarray[i])){tmpdiv.style.width=getwidth(objarray[i]);} if(getheight(objarray[i])){tmpdiv.style.height=getheight(objarray[i]);} if(getposition(objarray[i])){tmpdiv.style.position=getposition(objarray[i]);} if(getright(objarray[i])){tmpdiv.style.right=getright(objarray[i]);} if(getleft(objarray[i])){tmpdiv.style.left=getleft(objarray[i]);} |
