'with' is not allowed in strict mode.解决方法！

今天在最新的MyEclipse中导入了一个包含有jquery-1.6.2.js的项目。

结果编译器报错：'with' is not allowed in strict mode.

原因：由于js在严格模式下不允许使用with关键字！

分析：with语句的作用是将代码的作用域设置到一个特定的作用域中

比如：

如果不使用with关键字代码要写成这样：var qs = location.search.substring(1);
var hostName = location.hostname;
var url = location.href;
如果使用with关键字可以这样写： with (location){
    var qs = search.substring(1);
    var hostName = hostname;
    var url = href;
}

解决方案：

找到关键所在！那么只需要把with关键字对应的代码块中省略的关键字添加上，并把with删掉 保存就好了！！

当然这是我遇到的情况。。。。谨供大家参考！！！！！
