Question

这段代码带来了Firefox到IE8的不同结果：

var text = "[AMOUNT] MILES DEDUCTED IN [CABIN] FOR [ORIGIN]";
var splitArray = text.split(/[\[\]]/);
alert(splitArray.length);

在Firefox中，警报提供7。在IE中，它给出了5。

我试过......

但它不起作用。

请问好吗？谢谢！

下一个代码没有经过全面测试，但在快速测试中它运行正常：

获得IE8并减少分裂行为：

var text = "[AMOUNT] MILES DEDUCTED IN [CABIN] FOR [ORIGIN]";
var arr = text.match(/[^\[\]]+/g);
// arr is ["AMOUNT", " MILES DEDUCTED IN ", "CABIN", " FOR ", "ORIGIN"]

获得FF分裂行为：

var text = "[AMOUNT] MILES DEDUCTED IN [CABIN] FOR [ORIGIN]";
var arr = text.match(/[^\[\]]+|^(?=[\[\]])|[^\[\]]?(?=[\[\]]$)|[^\[\]]?(?=[\[\]]{2})/g);
// arr is ["", "AMOUNT", " MILES DEDUCTED IN ", "CABIN", " FOR ", "ORIGIN", ""]
