字符串切割时报错 TypeError: Cannot read property 'split' of undefined

//字符切割
var arr=edycL.split('-');
edycL=arr[1];
var arr2=edecL.split('-');
edecL=arr2[1];
对字符进行切割时报： TypeError: Cannot read property ‘split’ of undefined
应该是获取字符的，有为空的情况，
故修改如下：
//字符切割
var arr=(edycL || '').split('-');
edycL=arr[1];
var arr2=(edecL || '').split('-');
edecL=arr2[1];
这样就不会报错了。
