如何通过 Javascript 设置循环 iMacros？

1）我无法通过javascript添加设置循环imacros，我该如何添加它？

var macro;
    macro =  "CODE:";
    macro +=  "VERSION BUILD=8011895" + "\n"; 
    macro +=  "TAB T=1" + "\n"; 
    macro +=  "SET !ERRORIGNORE YES" + "\n"; 
    macro +=  "SET !EXTRACT_TEST_POPUP NO" + "\n"; 
    macro +=  "SET !TIMEOUT 3" + "\n"; 
    macro +=  "SET !EXTRACT NULL" + "\n"; 
    //macro +=  "SET !LOOP 1" + "\n"; 
    macro +=  "TAG POS={{loop}} TYPE=A ATTR=CLASS:twitter-timeline-link EXTRACT=TXT" + "\n"; 
    macro +=  "SAVEAS TYPE=EXTRACT FOLDER=* FILE=twitter.csv" + "\n"; 
    var extractedtext=iimGetLastExtract();
    iimPlay(macro);

2）我如何在没有javascript的imacros上使用该代码？ （关于国际管理学院）

var extractedtext=iimGetLastExtract(); 

将您的 imacros 代码指定为 javascript 字符串并使用前缀CODE:

var urls = ['http://google.com', 'http://yahoo.com'];

for (var i in urls) {
  var url = urls[i];
  var returnCode = iimPlay('CODE: URL GOTO='+url);
}
