我正在使用galaxy s4,android 4.2.2上的chrome移动浏览器,出于某种原因,每当我向下滚动页面时,它都会触发一个通过jquery.cycle2幻灯片放映图像验证的resize事件.

知道为什么会这样吗？

我有一个圆环图,里面有五个不同的弧形.数据不会更新,但我希望在页面加载时将整个图形转换为圆形,从选定的角度开始(在我的情况下为1.1*PI).这是图的jsfiddle:http://jsfiddle.net/Nw62g/

var data = [
    {name: "one", value: 10375},
    {name: "two", value:  7615},
    {name: "three", value:  832},
    {name: "four", value:  516},
    {name: "five", value:  491}
];

var margin = {top: 20, right: 20, bottom: 20, left: 20};
    width = 400 - margin.left - margin.right;
    height = width - margin.top - margin.bottom;

var chart = d3.select("body")
    .append('svg')
    .attr("width", width + margin.left + margin.right)
    .attr("height", height + margin.top + margin.bottom)
    .append("g")
    .attr("transform", "translate(" + ((width/2)+margin.left) + "," +
                                      ((height/2)+margin.top) …

我有应该创建三个子进程的代码，每个代码都将执行一个小的数学运算。然后，父级应该使用所有子进程的结果并获得最终答案，但我找不到在父级中实际读取子级结果的方法。有没有办法做到这一点？

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

int main(void)
{
   int pid1, pid2, pid3, status;
   int a=1, b=2, c=5, d=4, e=6, f=3, g;
   int t1, t2, t3;

   printf("Hello World!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!\n");
   printf("Here I am  before use of forking\n");
   printf("I am the PARENT process and pid is : %d\n",getpid());

   pid1 = fork( );
   if (pid1 == 0)
   {      
    printf("\n\nHere I am just after child forking1\n");
    printf("I am the Child process and pid1 is :%d\n",getpid());      
    printf("My parent's pid is :%d\n",getppid());   
    t1 = a+b;
    printf("The …
