JavaScript在数组中

问题描述

假设我有这个：

var blockedTile = new Array("118", "67", "190", "43", "135", "520");

还有更多的数组元素，但为了便于阅读，这些元素很少。无论如何，我可以做一个for循环但每次点击地图时它会做500个循环......有没有其他方法可以查看某个字符串是否在数组中？

There's more array elements but those are just few for readability purposes. Anyways, I could do a "for" loop but it would do 500 loops everytime you click on the map... is there any other way to see if a certain string is in an array?

推荐答案

试试这个：

if(blockedTile.indexOf("118") != -1)
{
   // element found
}
