# transclude、priority、terminal属性

## transclude

* transclude:指令元素中的原来的子节点移动到一个新模版内部
* 当为true时，指令会删掉原来的内容，使你的模版可以用ng-transclude指令进行重新插入

## priority && terminal

* priority:设置指令在模版中的执⾏行顺序，顺序是相对于元素上其他执⾏行而言，默认为0，从大到小的顺序依次执行
* 设置优先级的情况比较少，象ng-repeat,在遍历元素的过程中，需要angular先拷贝生成的模版元素，在应用其他指令，所以ng-repeat默认的priority是1000
* terminal 是否以当前指令的权重为结束界限。如果这值设置为 true ，则节点中权重小于当前指令的其它指令不会被执行。相同权重的会执行。

            replace: true,
            priority: 0,
            // 小于0的directive 都不会执行
            terminal:true
