复选框单元格

CheckBox 表示一种复选框单元格类型。当你想在你的页面添加用户可以填写的表单,那么复选框单元格将是非常有用,而且将会很简单的让用户去选择。

创建一个复选框单元格,参照以下代码: 复选框单元格类型 CheckBox 支持三种状态。你可以使用 isThreeState 方法来设置复选框是否支持三种状态。例如: 三种状态分别是选中,未选中和不确定状态。每种状态都有对应的文本;你可以使用 textTrue , textFalse和 textIndeterminate 方法来设置或者获取状态对应的文本。例如: 你可以使用 caption 方法来设置或者获取复选框单元格的标题。使用 textAlign 方法来设置或者获取文本相对于复选框的位置。这个设置是一个枚举 CheckBoxTextAlign, 枚举值如下: top: 文本在复选框顶部。 bottom: 文本在复选框底部。 left: 文本在复选框左边。 right: 文本在复选框右边。 你可以使用 boxSize 方法来获取或者设置复选框大小,可以设置数字或者"auto"。
