他在ie下也能选中文字,选中其他列表,不会选中文字,原来它是在不同div中,属于不同的范围,而同事是放在同一个table中,会选中。
而在firefox下,文字不会被选中,查看google calender的css,原来还有-moz-user-select这个属性,很好玩!
采用一个了js方法,即onselectstart=function{return false;},不让页面进行选择,呵呵,这是很多网站不让复制采用的方法。

Usage Examples

This sample code provides a simple "Hello, World!" text which prevents the user from selectg the content:

<span style="-moz-user-select: none;">

Notes

This property is similar to the property of CSS3.

When the 'none' value was applied to a headg element the content could still be selected.

Aordg to the W3C, the "User agent's default style sheet may override this value. For example, user agents typically do not allow selection of the contents of a BUTTON element. As the -moz-user-select was designed to mimic the user-select property, the same applies.

屏蔽选择的样式定义-moz-user-select属性(只支持ff)。
属性有三个属性值
1、 none用none,子元素所有的文字都不能选择,包括put输入框中的文字也不能选择。
2、 -moz-all子元素所有的文字都可以被选择,put输入框中的文字不可以被选择。
3、 -moz-none子元素所有的文字都不能选择,put输入框中的文字除外。
IE浏览器下是通过 onselectstart=”javascript:return false;”事件来实现该功能。
</pre>
</body>
</html>
-khtml-是苹果的那个浏览器的 好像现在使用-webkit-user-select: none
