Question

的index.html

    var app = angular.module('myApp',[]);
    app.run(function($rootScope){
    $rootScope.isDisabled = true;
    setTimeout(function(){
        $rootScope.isDisabled = false;
    },3000);

使用内置指令.js

#include <stdio.h> 
#include <stdlib.h> 
#include <string.h>

struct Result{
    int reversen;
    unsigned short count;
};

struct Result *myCount(int, int);
int main()
{
    struct Result *result;
    myCount(122333, 2);
    printf("\nReversed integer of 122333: %d", result->reversen);
    printf("\nOccurrence of 2 in 122333: %hu", result->count);  
    return 0;
}

struct Result * myCount(int n, int d)
{
    struct Result * result = (struct  Result *) malloc (sizeof (struct  Result));
    if (result == NULL)
    {
        fprintf(stderr, "\nNo storage space available\n");
        exit(0);
    }
    int rev_dig, last_dig, digit,  count = 0;
    while (n != 0)
    {
        last_dig = n % 10;
        rev_dig = rev_dig * 10 + last_dig;
        n = n / 10;
    }
    rev_dig = rev_dig * (-1);   
    result->reversen = rev_dig;

    while (n >= 1)
    {
        digit = n % 10;
        if (digit == d)
            count++;
        n = n / 10;
    }
    result->count = count;  
}

在开始时页面加载按钮保持禁用状态，但在3秒后它未启用。那是为什么？

Answer 1

当您使用setTimeout时，模型更改在角度上下文之外完成，因此它不会触发摘要。

替换：

setTimeout(function(){
    // ...
},3000);

与

$timeout(function(){
    // ...
}, 3000);

为什么ng-disabled在3秒后没有启用按钮？
