grootJs的属性绑定指令

index6.html

绑定文本text

gt-text="{属性名}"

绑定标签属性attr

gt-attr="vm属性名称(标签属性,value表达式)" 如 gt-attr="uid(id,'view'+value)"

绑定标签属性css

gt-css="vm属性名称(标签属性,value表达式)"

同attr

绑定标签属性class

1.gt-class="vm属性名称(class名称:value表达式,class名称:value表达式,class名称:value表达式...)"

class 的value表达式比较特殊 value表达式为true 就绑定对应的属性为fale 就不绑定对应的属性

2.gt-class-属性名="class名称:value表达式,class名称:value表达式,class名称:value表达式..." (可以绑定多个)
