$.inArray函数用法

解释: 确定第一个参数在数组中的位置, 从0开始计数(如果没有找到则返回-1)。

记得indexOf()方法了吗? indexOf()返回字符串的首次出现位置,而$.inArray()返回的是传入参数在数组中的位置,同样的,如果找到的,返回的是一个大于或等于0的值,若未找到则返回-1.现在, 知道怎么用了吧. 有了它, 判断某个值是否存在于数组中,就变得轻而易举了。

$.grep(arrayAllIndex,function(item){ 
         return $.inArray(item.secondPCode, types)!=-1&&item.indexName.toUpperCase().indexOf(likeword)>=0;  
   });

过滤掉arrayAllIndex中secondPCode不在types集合中的数据，likeword表示模糊搜索指标名称过滤

types：["0101","0102","0103","0104","0105","0106"]
