Check if html element exists with iMacros and javascript

问题:

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.

Because iMacros doesn't have statements, I used javascript with the iMacros' EVAL. Here is the line that handles the javascript execution:

SET !VAR3 EVAL("var element = window.content.document.getElementById(\"some_element\"); if (typeof(element) != 'undefined' && element != null) {  var redirect = 'http://192.168.178.22/sc/report.php';  } else {  var redirect = 'http://192.168.178.22/sc/index.php?action=connect';  }  redirect; ") 

*It's all in one line, but I formatted it for here.

Then, I will redirect with

URL GOTO={{!VAR3}} 

The problem is in both of the cases, the !VAR3 is set to 'undefined.'

I tried almost the same JS code on Firefox only, and it seems to be working.

Windows 8 with the latest Firefox and the latest iMacros version.

Thank you.

var macro;  macro ="CODE:"; macro +="TAG POS=1 TYPE=DIV ATTR=CLASS:some_class CONTENT=EVENT:MOUSEOVER ";  var ret=null;  ret=iimPlay(macro);  if(ret>0) { //do something } else { //do something else } 

This would be the basic model of the script you want. You just have to insert the proper imacros code.
