jQuery / JavaScript脚本在IE7上不起作用

Question

我在Internet EXPLODER 7.0上遇到jquery / javascript问题。在现代浏览器（包括IE 8和9）上，一切都很完美。 IE 7不隐藏元素，不显示datepicker - 总的来说，脚本不像其他“普通”浏览器那样工作。

这是我的jsfiddle：http://jsfiddle.net/W7NHK/

我将不胜感激任何帮助！

这是我的HTML：

Answer 1

你这里有一个语法错误：yearRange: '1950:2010',

问题出在尾随逗号。

请参阅此处的说明：Are trailing commas in arrays and objects part of the spec?
