imacros javascript multiple for loops内循环过程提取数据

问题描述

我想找到一种方法来循环所有国家。

i am trying to figureout a way to loop all countries.

我在脚本下面有3个循环.Loop＃2,3工作正常。但循环＃1不是。
这里是逻辑 - 主要的alexa网站www.alexa.com/topsites/countries，这有多个国家，每个国家都有2个字符后缀。对于每个国家/地区编号，前缀为获取国家/地区列表

I have below script it has 3 loops.Loop # 2, 3 working fine. but Loop #1 is not.here is the logic - main alexa site www.alexa.com/topsites/countries and this has multiple countries each country has a 2 charecter suffix. for each country number is prefixing to get country listing.

流程：1。循环＃1访问www.alexa.com/topsites/countries并循环所有国家。（此部分不起作用）2.loop＃2对于每个国家/地区循环所有页面（此部分也有效）3。循环＃3为每个页面收集数据。 （这部分工作）

process: 1. loop#1 go to www.alexa.com/topsites/countries and loop all countries.(this part does not work) 2.loop#2 for each country loop all pages(this part also working) 3. loop# 3 for each page collect data. (this part is working)

var jsLF="\n";

var macro;
macro =  "CODE:";
macro += "VERSION BUILD=9002379" + jsLF;
macro += "TAB T=1" + jsLF;
macro += "TAB CLOSEALLOTHERS" + jsLF;
macro += "TAG POS={{i}} TYPE=A ATTR=HREF:* EXTRACT=TXT" + jsLF;
macro += "SAVEAS TYPE=EXTRACT FOLDER=C:\\   FILE=hiprsites.txt" + jsLF;

var macro1;
macro1  =  "CODE:";
macro1 +=  "VERSION BUILD=9002379" + jsLF;
macro1 +=  "TAB T=1" + jsLF;
macro1 +=  "TAB CLOSEALLOTHERS" + jsLF;
macro1 +=  "URL GOTO=http://www.alexa.com/topsites/countries;{{j}}/ID" + jsLF;

var macroAllC;
macroAllC  =  "CODE:";
macroAllC +=  "VERSION BUILD=9002379" + jsLF;
macroAllC +=  "TAB T=1" + jsLF;
macroAllC +=  "TAB CLOSEALLOTHERS" + jsLF;
macroAllC +=  "URL GOTO=http://www.alexa.com/topsites/countries;{{z}}" + jsLF;


//LOOP #1
//loop all countries take one country and go to next loop
for (var z=0;z<200;z++)
{
iimDisplay(z);
iimSet("z", z);
iimPlay(macroAllC);

//LOOP #2
//loop all the pages for each page get data
for (var j=0;j<20;j++)
{
iimDisplay(j);
iimSet("j", j);
iimPlay(macro1);

//LOOP #3
//loop the current page and get all 25 result
for(var i=1;i<=25;i++)
{
iimDisplay(i);
iimSet("i", i);
iimPlay(macro);
iimSet("i",i);
}//loop individual pages
}//loop macro1

推荐答案

首先，您需要提取临时数组中的所有国家/地区：

First of all you need to extract all countries in a temporary array:

var countries = new Array(), i = 4;
do
{
iimDisplay("Extracting " + i);
iimSet("i", i);
iimPlay("CODE:TAG POS={{i}} TYPE=A ATTR=HREF:*countries* EXTRACT=HREF");
  if(iimGetLastExtract()!='#EANF#')
      countries.push(iimGetLastExtract());
        else break;
i++;
}
while(i);

我设置 i = 4 到得到第一个国家 AF

I'm setting i=4 to get the first country AF

然后你必须遍历每个国家页面并提取另一个国家的所有数据数组：

Then you will have to loop through each country page and extract all data in another temporary array:

for(i=0;i<countries.length;i++)
  {
   var j = 2;
   iimSet("url", countries[i]);
   iimPlay("CODE:URL GOTO={{url}}");

   do
    {
    iimDisplay("Loop " + (i+1) + " of " + countries.length + "\nExtracting " + j);
    iimSet("j", j);
    iimPlay("CODE:SET !TIMEOUT_STEP 1\nTAG POS={{j}} TYPE=A ATTR=HREF:*siteinfo* EXTRACT=HREF");
     if(iimGetLastExtract()!='#EANF#')
        temp_pages.push(iimGetLastExtract());
         else
          {
           iimPlay("CODE:TAG POS=1 TYPE=A ATTR=TXT:Next");
            if(iimGetLastError()=='OK')
               j = 1;
                else
                 break;
           }
     j++;
    }
  while(j);
 }

现在我们将所有国家/地区的所有网页存储在 temp_pages 数组，你必须循环并提取你需要的数据：

Now we have all pages from all countries stored in temp_pages array, which you will have to loop and extract the data you need:

for(i=0;i<temp_pages.length;i++)
     {iimDisplay("Loop " + (i+1) + " of " + temp_pages.length);
      iimSet("url", temp_pages[i]);
      iimPlay("CODE:URL GOTO={{url}}");
      j = 1;
 do
{
iimSet("j", j);
iimPlay("CODE:TAG POS={{j}} TYPE=A ATTR=HREF:* EXTRACT=TXT");
 if(iimGetLastExtract()!='#EANF#')
   {
    iimSet("ext", iimGetLastExtract());
    iimPlay("CODE:SET !EXTRACT {{ext}}\nSAVEAS TYPE=EXTRACT FOLDER=C:\\ FILE=hiprsites.txt");
 }
  else break;
  j++;
  }
   while(j);
}

因此您将拥有 hiprsites.txt 很多锚点（不知道为什么需要这些信息）。如果要提取 hrefs ，则更改 TAG POS = {{j}} TYPE = A ATTR = HREF：* EXTRACT = TXT 到 TAG POS = {{j}} TYPE = A ATTR = HREF：* EXTRACT = HREF 。

As a result you will have in hiprsites.txt a lot of anchors (don't know why you need this information). If you want to extract hrefs, then change TAG POS={{j}} TYPE=A ATTR=HREF:* EXTRACT=TXT to TAG POS={{j}} TYPE=A ATTR=HREF:* EXTRACT=HREF.

祝你好运）
