推荐答案

使用J-query你可以保持复选框的状态。



取一个隐藏字段并将此隐藏字段值设置为1（如果用户选中复选框）和0如果用户取消选中该复选框

现在在document.ready函数上检查隐藏字段值并相应地勾选/取消选中该复选框。

Using J-query you can maintain the state of the check box.

Take a hidden field and set this hidden field value to 1 ,if user checks the check box and 0 if user unchecked the checkbox
Now on document.ready function check the hidden-field value and check/unchecked the checkbox accordingly.
