I have the following code that works fine in IE8, firefox, chrome but not in IE7
我有以下代码在IE8,Firefox,Chrome中工作正常但在IE7中没有
Can someone please explain why this code below doesn't work in IE7 ?
有人可以解释为什么下面的代码在IE7中不起作用?
var myString = $(this).attr("id");
var nextStep = myString [myString.length - 1];
basically, IE7 doesn't seem to understand this line:
基本上,IE7似乎并不理解这一行:
myString [myString.length - 1]
In this case myString is just a regular string that i am parsing out from the id of a div.
在这种情况下,myString只是一个常规字符串,我从div的id解析出来。

IE7 does not recognize indexing a string in that way. You need to use myString.charAt(myString.length - 1)
.
IE7无法识别以这种方式索引字符串。您需要使用myString.charAt(myString.length - 1)。
Array-like indexing of a string was added to ECMAScript 5, which was released well after IE7 was. More info
类似于数组的字符串索引被添加到ECMAScript 5,它在IE7之后很好地发布了。更多信息
