第二步:建立Foreach循环容器。 选择Foreach ADO 枚举器。 对象源变量选择之前定义的DeclNOs。 变量映射中,定义变量对应结果集中第一列数据,即索引0处。(如果select很多列,每一次foreach出来的是以行为单位的,显示一行的 第几列),index在此时就是某一行中的某个列。 然而对于foreach的源是file system的就不行了...

//function(n){for(var i = 0; i < this.length; i++) {if(this[i] == n){returni +'-indexOf'; } };return-1; } 为什么会这样?得先知道一个原理:预定义的属性不是可枚举的,而用户定义的属性总是可枚举的。 在IE8以上的浏览器中,indexOf会被认为是预定义属性,使用for in时自然不会被枚举...
