我使用的是“与cookies模仿的iGoogle教程”由詹姆斯·Padolsey http://james.padolsey.com/tag/cookies/IE6-7的Javascript
我也遇到一个问题与IE6 & 7解释JavaScript的方式。我发现了这个问题，但我无法解决这个问题。
下面的代码很长，但这个问题只在一个小部分

如果我离开这个部分留空
widgetIndividual : {
static: {
movable: false,
removable: true,
collapsible: true,
editable: false,
}
}
例如，像这样的
widgetIndividual : {
}
然后，它在所有浏览器上都能正常工作，不幸的是我需要为我的专业版使用单独的Widget设置JECT。
IE6-7抛出一个错误，因为这些家伙“}”，我不知道为什么。
正如ShankarSangoli所说，存在语法错误。在IE 6和7以外的许多浏览器中，该代码都会失败。ES5中允许使用尾随逗号，但并非所有浏览器都能加速。 – RobG
@RobG - 最后的逗号错误出现在只有IE浏览器的浏览器中，所有浏览器都满意。 – ShankarSangoli
“AlL”其他浏览器？你测试了哪些？这特别是ES3中的一个语法错误，尽管一些浏览器可以容忍它。仍有许多浏览器仍在使用中，这是不允许的。我不记得哪些是因为我在很多年以前没有触发过这个错误，但它曾经是所有这些错误（至少是Firefox和Safari 2）。 – RobG
