我将变量声明如下：
jsonDataGas: any;
sortJsonDataPrice: any;
sortJsonDataDistance: any;
在构造函数中我需要填充每个变量（sortJsonDataPrice，sortJsonDataDistance），对变量jsonDataGas中的主数组进行排序
constructor(public navCtrl: NavController, public navParams: NavParams, private superTabsCtrl: SuperTabsController) {
this.jsonDataGas = navParams.get('jsonDataGas');
console.log(this.jsonDataGas);
this.sortJsonDataPrice = this.jsonDataGas.sort((a,b) => {
let nameA=a.label_gas.toLowerCase(), nameB=b.label_gas.toLowerCase()
return a.price-b.price || nameA < nameB;
});
console.log(this.sortJsonDataPrice);
this.sortJsonDataDistance = this.jsonDataGas.sort((a,b) => {
return a.distanceorigin-b.distanceorigin;
});
console.log(this.sortJsonDataDistance);
console.log(this.jsonDataGas);
}
当打印变量时，它们都保持相同的顺序，主变量jsonDataGas被修改。
我没有使用过此框架，并希望得到任何帮助。
答案 0 :(得分：1)
JavaScript Array.prototype.sort就地排序。也就是说，它会修改它正在运行的阵列。您第一次拨打this.jsonDataGas.sort以特定方式对this.jsonDataGas进行排序，然后您的第二次通话以另一种方式对其进行排序。
由于您需要两个独立排序的数组，因此首先需要copy它们。试试this.jsonDataGas.slice().sort(...)，其中slice为您提供阵列的浅层克隆。请注意，由于克隆很浅，因此它不会复制基础对象。因此，如果您执行this.sortJsonDataPrice[0].timetext = 'bla'，那么也会修改this.sortJsonDataDistance（和this.jsonDataGas）中的某些元素。
