如何在一个 iMacros 脚本中使用多个循环进行锻炼？

Question

我希望每个人都完美 health.I 我正在尝试在我的 iMacros 脚本中添加两个 for 循环，但只有第一个循环有效，然后停止脚本并且不会前进到第二个循环并以以下错误结尾：

TypeError: a is undefined, line 15 (Error code: -991)

脚本：

var test;
test ="CODE:";
test +="SET !ERRORIGNORE YES "+" \n";
test +="TAB T=1"+" \n";
test +="URL GOTO=http://clicksandearns.com/index.php?tp=paidclicks "+" \n";

iimPlay(test);


var a_list = window.content.document.getElementsByTagName("a");

X = 1;
for (var i = 0, len = a_list.length; i <= len; i++) {
    var a = a_list[i];
    if (a.href.indexOf("tp=visit") > -1) {
var test;
test ="CODE:";
test +="SET !ERRORIGNORE YES "+" \n";
test +="' AD FIRST "+X+" \n";
test +="TAB OPEN "+" \n";
test +="TAB T=2"+" \n";
test +="URL GOTO="+a.href+" \n";
test +="WAIT SECONDS=13 "+" \n";
test +="FRAME NAME=visit "+" \n";
test +="TAG POS=1 TYPE=INPUT:SUBMIT FORM=NAME:ss ATTR=TYPE:Submit&&NAME:submit&&VALUE:Continue<SP>for<SP>Credit "+" \n";
test +="WAIT SECONDS=2 "+" \n";
test +="TAB CLOSE"+" \n";


iimPlay(test);
X++;
    } 

    }

var test;
test ="CODE:";
test +="SET !ERRORIGNORE YES "+" \n";
test +="TAB T=1"+" \n";
test +="URL GOTO=http://clicksandearns.com/index.php?tp=paidclicks&st=&s=&start=35 "+" \n";

iimPlay(test);


var a_list = window.content.document.getElementsByTagName("a");

X = 1;
for (var i = 0, len = a_list.length; i <= len; i++) {
    var a = a_list[i];
    if (a.href.indexOf("tp=visit") > -1) {
var test;
test ="CODE:";
test +="SET !ERRORIGNORE YES "+" \n";
test +="' AD LAST "+X+" \n";
test +="TAB OPEN "+" \n";
test +="TAB T=2"+" \n";
test +="URL GOTO="+a.href+" \n";
test +="WAIT SECONDS=13 "+" \n";
test +="FRAME NAME=visit "+" \n";
test +="TAG POS=1 TYPE=INPUT:SUBMIT FORM=NAME:ss ATTR=TYPE:Submit&&NAME:submit&&VALUE:Continue<SP>for<SP>Credit "+" \n";
test +="WAIT SECONDS=2 "+" \n";
test +="TAB CLOSE"+" \n";


iimPlay(test);
X++;
    } 

    }

期待是否有人可以帮助我解决这个问题或解决这个问题一些其他替代方案way.Will感谢您的帮助..！

你的 for 循环有一个错误：

for (var i = 0, len = a_list.length; i <= len; i++) {

应替换为：

for (var i = 0, len = a_list.length; i < len; i++) {

没有索引为 len 的项目 - 只有 len-1... 因此，在尝试读取 undefined

的 href 属性时出现异常
