I want to check if an HTML element exist with iMacros. If it does, I want to go to a URL. If not, I want to go to other URL.<\/p>\n

Because iMacros doesn’t have statements, I used javascript with the iMacros’ EVAL. Here is the line that handles the javascript execution:<\/p>\n

SET !VAR3 EVAL(\"var element = window.content.document.getElementById(\\\"some_element\\\");\nif (typeof(element) != 'undefined' && element != null) { \nvar redirect = 'http:\/\/192.168.178.22\/sc\/report.php'; \n} else { \nvar redirect = 'http:\/\/192.168.178.22\/sc\/index.php?action=connect'; \n} \nredirect;\n\")\n<\/code><\/pre>\n
*It’s all in one line, but I formatted it for here.<\/p>\n
Then, I will redirect with<\/p>\n
URL GOTO={{!VAR3}}\n<\/code><\/pre>\n
The problem is in both of the cases, the !VAR3 is set to ‘undefined.’<\/p>\n
I tried almost the same JS code on Firefox only, and it seems to be working.<\/p>\n
Windows 8 with the latest Firefox and the latest iMacros version.<\/p>\n
Thank you.<\/p>\n

    This would be the basic model of the script you want. You just have to insert the proper imacros code.<\/p>\n<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
