Question

这是一个了解我正在尝试做什么的人： http://plnkr.co/edit/mYFNBC6Z2XdpFD28XLdq?p=preview

我正在定义一个默认排序，并希望能够根据范围变量进行设置，例如：

<th st-sort-default="{{order}}" st-sort="balance">balance</th>

然而，这似乎并没有起作用，我不确定这样做的正确方法。

Stackoverflow说我需要包含代码，所以这里是来自plunker的index.html和script.js：

＆＃13;

angular.module('myApp', ['smart-table']).
controller('mainCtrl', ['$scope', '$timeout', function($scope, $timeout) {
  var nameList = ['Pierre', 'Pol', 'Jacques', 'Robert', 'Elisa'],
      familyName = ['Dupont', 'Germain', 'Delcourt', 'bjip', 'Menez'];

  function createRandomItem() {
    var firstName = nameList[Math.floor(Math.random() * 4)],
        lastName = familyName[Math.floor(Math.random() * 4)],
        age = Math.floor(Math.random() * 100),
        email = firstName + lastName + '@whatever.com',
        balance = Math.random() * 3000;

    return {
      firstName: firstName,
      lastName: lastName,
      age: age,
      email: email,
      balance: balance
    };
  }


  $scope.displayed = [];
  for (var j = 0; j < 50; j++) {
    $scope.displayed.push(createRandomItem());
  }

  // Does not work
  $scope.order = "";
  // Works
  //$scope.order = "reverse";
}]);

Answer 1

st-sort-default中的空字符串将被忽略。从 smart-table.debug.js 中的第282行开始：

if (attr.stSortDefault) {
   sortDefault = scope.$eval(attr.stSortDefault) !== undefined ?    scope.$eval(attr.stSortDefault) : attr.stSortDefault;
}

我建议您使用st-sort-default="default"。但是，任何字符串都会这样做。

第{308}行reverse

中有一项具体检查

if (sortDefault) {
   index = attr.stSortDefault === 'reverse' ? 1 : 0;
   sort();
}
