在有效模糊上调用函数

Question

PLUNKER

如果元素有效,我怎么能在模糊时触发函数调用没有其他错误？

HTML

<input type="text" id="order" ng-model="order" name="order" class="form-control" 
    ng-pattern="/^[0-9]*$/" ng-minlength="9" maxlength="9"
    required="" ng-blur="something()"  />

JS

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {
    $scope.something=function(){
      if($scope.routingNumber.$valid)
        alert("yippie");
    }
});

在这里你去:http://plnkr.co/edit/g4ecmWToQPbOKAk3XvNt？p = preview(完整表格) http://plnkr.co/edit/Zep8D4AXvkzwpqcFFXjR?p=preview(仅限订单字段)

你只需form要将你的something方法传递给你.

<input type="text" id="order" ng-model="order" name="order" class="form-control" 
 ng-pattern="/^[0-9]*$/" ng-minlength="9" maxlength="9"
 required="" ng-blur="something(myform)"  />

在你的JS中:

app.controller('MainCtrl', function($scope) {
  $scope.something = function(form) {
    if (form.order.$valid) {
      alert("yippie");
    }
  }
});
