Question

我正在使用bootstrap进行角度下拉列表。我创建了一个指令，用户从下拉列表中选择菜单选项并提醒用户。

我在这里创建了一个plnkr

  (function() {
  'use strict';

  angular.module('plunker').directive('exportData', exportData);

  function exportData() {
    var controller = function() {

        var vmd = this;

        vmd.exportAction = [{
          id: 1,
          action: 'Export all -> excel',
          visble: true
        }, {
          id: 2,
          action: 'Export selected -> excel',
          visble: true
        }, {
          id: 0,
          action: '',
          visble: true,
          divider: true
        }, {
          id: 3,
          action: 'Export all -> pdf',
          visble: true
        }, {
          id: 4,
          action: 'Export selected -> pdf',
          visble: true
        }];

        function activate() {} //activate

        activate();

        vmd.selectedExport = function(action) {
          alert("you selected " + action.action);
        };

      } //controller

    return {
      restrict: 'EA',
//      scope: {
//        datasource: '=',
//      },
      controller: controller,
      controllerAs: 'vmd',
      templateUrl: 'exportData.html',
      bindToController: true
        //link: function ($scope, element, attrs) {
        //    });
    };
  };
}());

任何想法，谢谢。

您在plunkr示例http://plnkr.co/edit/YH4A5bb1o3ss5ECD0j8g

中缺少

if (!char.IsControl(e.KeyChar) && !char.IsDigit(e.KeyChar) && (e.KeyChar != '.') && (e.KeyChar != '-'))
{
     e.Handled = true;
}

 // only allow one minus -

//put condition if it is zero than only allow one minus sign
if (e.KeyChar == '-' && ((sender as TextBox).Text.IndexOf('-') > -1) && minusCount==0)
{
     e.Handled = true;
     //over here increment that variable
     minusCount = minusCount+1;
     //for handling it in middle other than zero position
     if(textbox.Text.IndexOf("-")>1)
     {
        textbox.Text=textbox.Text.Replace("-","");
     }
}

Angular指令不显示
