离子后退按钮也显示在上一页

Question

我使用以下代码在嵌套页面中显示后退按钮（＆＃39; menu.settings.term_of_service＆＃39;）：

public static int indexOfMaxInRange(int[] a, int lowIndex, int highIndex){
    if((highIndex - lowIndex) == 0){
        return highIndex;
    }else if(a[lowIndex] >= a[highIndex]){
        //Changed to recursive call
        return indexOfMaxInRange(a, lowIndex, highIndex - 1);
    }else{
        //Changed to recursive call
        return indexOfMaxInRange(a, lowIndex + 1, highIndex);
    }  
}
public static void main(String[] args) {
    int[] a = new int[5];
    a[0] = 4;
    a[1] = 3;
    a[2] = 6;
    a[3] = 4;
    a[4] = 2;
    System.out.println(indexOfMaxInRange(a, 0, a.length - 1));
}

这里也是routes.js：

<ion-nav-buttons side="left">
    <button class="button icon ion-chevron-left"  ui-sref="menu.settings" ></button>
</ion-nav-buttons>

问题在于，当我按下它时，在页面中（＆＃39; menu.settings＆＃39;）它仍会显示后退按钮，以便在菜单中再次返回.settings.term_of_service＆＃39 ;页面而不是＆＃39;菜单＆＃39;酒吧。有什么想法吗？
