Angularjs 在$evalAsync之后是否可以防止另一个$digest？

示例场景

伪码

---

撇开此处可能出现的无休止循环不谈-是否可以取消

$evalAsync

中的下一个

$digest

？

供将来参考，我将回答自己的问题。。。。它可以通过

$$postdgest

scope.set_value ( user_input ) { 

    scope.value = user_input;

    // trigger digest : evaluation of several validators

    // execute after digest and prior to DOM rendering
    scope.$$postDigest(function() {

        // check if the value is valid based on 
        // validators calculated during the last digest

        if ( !scope.is_valid() )
            // trigger another digest with null value
            scope.$apply( function () {  scope.value = null; });

        // NO CHANGE
    }); 

scope.set_value ( user_input ) { 

    scope.value = user_input;

    // trigger digest : evaluation of several validators

    // execute after digest and prior to DOM rendering
    scope.$$postDigest(function() {

        // check if the value is valid based on 
        // validators calculated during the last digest

        if ( !scope.is_valid() )
            // trigger another digest with null value
            scope.$apply( function () {  scope.value = null; });

        // NO CHANGE
    });
