昨天对“圳品”信息系统中的通用的checkbox全选、全部取消、反选函数内部代码进行了修改完善，在Edge浏览器中运行正常。详见：利用eval（)打造通用的checkbox全选、全部取消、反选函数升级版+2
今天测试发现代码在editplus（应该是调用IE浏览器）中运行时会出错，比如点击“全部取消”按钮： 
经分析研究，决定先对checkbox进行判断，再检测是否有checked属性值。
调试发现checkbox的值为“[object HTMLInputElement]”，那么我们对通用函数代码进行修改，比如全选按钮函数代码改为：
//全选,s:checkboxname function checkAll(s) { var i = 0; while (eval（s)[i]=="[object HTMLInputElement]" && typeof(eval（s)[i].checked)!="undefined") { eval（s)[i++].checked = true; } }
完整的代码如下：

在EditPlus中的运行效果如下：
