错误的函数声明全局规则部分发出时，函数声明后没有分号？
|
这是两个规则集，它们说明了完全意外的行为。这是一个错误吗？
即使未在任何地方调用函数或由于JavaScript错误导致脚本中断，函数也会执行。解决方案是始终以这样的分号结束声明：
test1 = function(){console.log(\"test1\");} ;// <==
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);})()
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);})()

test2 = function(){console.log(\"test2\")};test2 = function(){console.log(\"test2\");};方法调用。 当您发出无效的javascript时，很可能会发生各种奇怪的事情。尽管大多数情况都会导致javascript语法错误，但KNS用于包装代码（并防止意外的变量泄漏）的闭包可能会产生副作用。 简而言之：如果这里有错误，那就是javascript解析器的灵活性，可让您省略重要的分号。这不被视为KRL错误。
