我正在使用 James Padolsey 的“使用 cookies 模仿 igoogle 教程” http://james.padolsey.com/tag/cookies/
我在 IE6 和 7 解释 javascript 的方式上遇到了问题。我发现了问题，但没有办法解决它。
下面的代码很长，但问题只是一小部分

如果我将此部分留空
widgetIndividual : {
static: {
movable: false,
removable: true,
collapsible: true,
editable: false,
}
}
比如这样
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项目使用单独的小部件设置。
IE6-7因为这些家伙“}”而抛出错误，我不知道为什么。
最佳答案
删除该对象中的最后一个逗号，它将起作用。
widgetIndividual : {
static: {
movable: false,
removable: true,
collapsible: true,
editable: false
}
}
