有条件地在javascript代码中隐藏一段json

Question

我想有条件地隐藏破坏性文本属性，这可能吗？所以，假设有一个名为showDelete 的变量。我想显示破坏性文本仅在showDelete = true 时显示。是否可以有条件地将其从 json 中排除？

  $ionicActionSheet.show({
      buttons: [
        { text: 'Share' },
        { text: 'Report'},
      ],
      destructiveText: 'Delete', //I want to hide this delete element when showDelete is false
      titleText: 'Actions',
      cancelText: 'Cancel',
      cancel: function() {
            // add cancel code..
      },
      ...

Answer 1

在函数调用之外定义您的配置对象，然后您可以使用条件修改属性以及使用angular.extend()等方法

var opts = {
      buttons: [
        { text: 'Share' },
        { text: 'Report'},
      ],

      titleText: 'Actions',
      cancelText: 'Cancel',
      cancel: function() {
            // add cancel code..
      }
} 

if(showDelete){
   opts.destructiveText = 'Delete';
}

 $ionicActionSheet.show(opts);
