这里有两个规则集说明了一个完全出乎意料的行为。这是一个错误吗？
即使没有在任何地方调用函数或脚本因 javascript 错误而中断，函数也会被执行。解决方案是始终以分号结束声明，如下所示：
test1 = function(){console.log("test1");} ;// <==
但我认为这很危险，因为这在 javascript 中不是强制性的。
示例 1 小书签：
javascript:(function(){
var d=document;var s=d.createElement('script');s.text="
KOBJ_config={'rids':['a1135x27']};";d.body.appendChild(s);
var l=d.createElement('script');l.src='http://init.kobj.net/js/shared/kobj-static.js';
d.body.appendChild(l);})()
示例 2 小书签：
javascript:(function(){
var d=document;var s=d.createElement('script');s.text="

var l=d.createElement('script');l.src='http://init.kobj.net/js/shared/kobj-static.js';
d.body.appendChild(l);})()
