bindfocus	EventHandle		输入框聚焦时触发，event.detail = {value: value}
bindblur	EventHandle		输入框失去焦点时触发，event.detail = {value: value}
bindlinechange	EventHandle		输入框行数变化时调用，event.detail = {height: 0, heightRpx: 0, lineCount: 0}
bindinput	EventHandle		当键盘输入时，触发 input 事件，event.detail = {value, cursor}， bindinput 处理函数的返回值并不会反映到 textarea 上
bindconfirm	EventHandle		点击完成时， 触发 confirm 事件，event.detail = {value: value}

auto-height 高度自动

placeholder	String		输入框为空时占位符
placeholder-style	String		指定 placeholder 的样式
placeholder-class	String	textarea-placeholder	指定 placeholder 的样式类

focus
