数据表的问题 - 错误类型错误：val.slice不是一个函数

val.slice is not a function

dataTable的配置

$.p-dataTable #dt [value]="customers" [(selection)]="chkBoxSelect" 
dataKey="customerId" [rows]="10" [paginator]="true" 
paginatorPosition="both" [pageLinks]="5" [rowsPerPageOptions]="[5,10,20]" 
[globalFilter]="gb" [headerCheckboxToggleAllPages]="false" 
[editable]="true" exportFilename="customers" [lazy]="true" 
[totalRecords]="totalRecords" onLazyLoad)="loadCustomersByPage($event)"

回调函数

$loadCustomersByPage(event: LazyLoadEvent) { 

    const parameters = "?page=" + event.first + "&size=" + (event.first + event.rows); 

    this._cs.findAllActiveCustomerDetailsByPage(parameters).subscribe(
     (data: any) => { 
     this.customers = data; 
     }, 
     (error) => { 
      console.log("--error--" + error) 
     } 
); 
}

我的问题解决了。这是我的错误。数据不是适当的对象 – Hari

你能否提供适当的对象类型？ – DenisK

看起来数据格式不正确..

这是分配给表的数据对象应该怎么样子：

let cars = [ 
    {"brand": "VW", "year": 2012, "color": "Orange", "vin": "dsad231ff"}, 
    {"brand": "Audi", "year": 2011, "color": "Black", "vin": "gwregre345"}, 
    {"brand": "Renault", "year": 2005, "color": "Gray", "vin": "h354htr"}, 
    {"brand": "BMW", "year": 2003, "color": "Blue", "vin": "j6w54qgh"}, 
    {"brand": "Mercedes", "year": 1995, "color": "Orange", "vin": "hrtwy34"}, 
    {"brand": "Volvo", "year": 2005, "color": "Black", "vin": "jejtyj"}, 
    {"brand": "Honda", "year": 2012, "color": "Yellow", "vin": "g43gr"}, 
    {"brand": "Jaguar", "year": 2013, "color": "Orange", "vin": "greg34"}, 
    {"brand": "Ford", "year": 2000, "color": "Black", "vin": "h54hw5"}, 
    {"brand": "Fiat", "year": 2013, "color": "Red", "vin": "245t2s"} 
]

如果你期待JSON-格式化数据，包括.json()方法：

this._cs.findAllActiveCustomerDetailsByPage(parameters).subscribe(
     (data: any) => { 
     this.customers = data.json(); 
     },`enter code here`
