如何从路径角度rc4恢复数据

Question

在应用路线中

：

＆＃13;

＆＃13;

{ path: 'calculator', component: CalculatorComponent, data: {physical: Physical}},

＆＃13;

＆＃13;

＆＃13;

设置comoponent中的

：

＆＃13;

＆＃13;

if(this.selectedPhysical) {
   this.router.navigate(['/calculator', this.selectedPhysical ]);
}

＆＃13;

＆＃13;

＆＃13;

导航的结果是试图这样做（这显然是错误的）：

＆＃13;

＆＃13;

http://localhost:3000/calculator;pK_Physical=4;fK_Measurement=2;dateString=5/22/2016;weight=270;height=70;hips=27;waist=51;neck=18.5

＆＃13;

＆＃13;

＆＃13;

那么如何将数据传递给路线？

在计算器组件中，我有以下内容。如何检索传入的路径数据？

＆＃13;

＆＃13;

ngOnInit() {
    this.route
       .data
       .subscribe(v => this.selectedPhysical = <Physical>v);
            
   console.log("phys = " + this.selectedPhysical);
}

＆＃13;

＆＃13;

＆＃13;

任何人都知道如何做到这一点？

Answer 1

您需要将依赖于更新数据的代码移动到subscribe(...)回调

中

ngOnInit() {

   ** problem is here **, I've tried every combination of things and nothing works.  Its always undefine.

   this.route
       .data
       .subscribe(v => {
            this.selectedPhysical = <Physical>v;
            console.log("phys = " + this.selectedPhysical);
       });

   // don't know about these          
   this.selectedSex = this.userSettings.sex;

   //console.log('route id =' + this.route.snapshot.params.id)
}
