Question

我有一个检查值是true还是false的函数以及一个改变值的函数。

checkValue(item){  
    if item.exists{  
        return 1;  
    }  
    else {  
        return 0;  
    }  
}

在我的html中，我有一个ng-repeat按此函数命令：

<span ng-repeat="item in items | orderBy: checkValue"></span>
<a ng-click="changeItemExists(selectedItem)">

现在，当item.exists更改orderBy时，item.exsist无效并再次订购。

如何让订单查看import java.util.Scanner; public class week4 { public static void main(String[] args) { { String studentname; int mark = 100; // listing maximum mark Scanner inText = new Scanner(System.in); System.out.print("Please enter the name of the student >> "); studentname = inText.nextLine(); Scanner inNumber = new Scanner(System.in); System.out.print("Please enter mark for student " + studentname + " out of 100 >> "); mark = inText.nextInt(); if(mark <50) System.out.print("The grade for " + studentname + " is F " ); else if(mark <65) System.out.print("The grade for " + studentname + " is P " ); else if(mark <75) System.out.print("The grade for " + studentname + " is C " ); else if(mark <85) System.out.print("The grade for " + studentname + " is D " ); else System.out.print("The grade for " + studentname + " is HD2" ); } } }？

中的任何更改

Answer 1

您不需要checkValue功能。只是做：

<span ng-repeat="item in items | orderBy: 'exists'"></span>

然后，orderBy会自动刷新订单，并对“存在”进行任何更改。属性。

如何在每次更改时刷新orderBy
