Question

这是我的角度代码，我需要通过var myval = "aaa,,,,bbb,,,,,,,ccc,,,,,,,,ddd,,,,,,,eee"; do { myval = myval.replace(/,,/g, ','); } while (myval.indexOf(",,") > 0); console.log(myval);函数接收对象，这个对象在ng-option中循环。但它不起作用;返回changeFilterOption(filter)。

undefines

Answer 1

在*.js文件中，您可以watch进行更改： -

$scope.$watch('your-model-name', function (newValue, oldValue){ 
    //newVal is the changed value
});

Answer 2

如果您需要将所选值传递给changeFilterOption函数，那么这不是您需要遵循的方式，请尝试这样，

<select ng-change="changeFilterOption(attribute[' + countInc + '].name)" ng-model="attribute[' + countInc + '].name" ng-options="filter.name as filter.uiName for filter in filters">

这是demo

然后select的值将传递给changeFilterOption(filter)参数中的filter。

如果您希望将filter对象传递给changeFilterOption(filter)，则需要修改select，如下所示，

<select ng-change="changeFilterOption(attribute[' + countInc + '].name)" ng-model="attribute[' + countInc + '].name" ng-options="filter as filter.uiName for filter in filters">

这将选择filter作为select值，并将filter.uiName显示为选项文字。

这是DEMO

Answer 3

试试这个

        <select ng-change="changeFilterOption(filter)" class="js-example-basic-single form-control" ng-model="attribute[' + countInc + '].name" ng-options="filter as filter.uiName for filter in filters"></select>

          $scope.changeFilterOption=function(filter){
                     console.log(filter);//undefined
            };

ng-change无法使用ng选项
