问题:

I am trying to use iMacros with Firefox to click an UnFollow button ONLY if this code exist on the page...

<small class="follow-status">follows you</small>

If the above does not exist in the page source then it would run this iMacros code...

TAG POS=1 TYPE=DIV ATTR=TXT:UnFollow

From what I have read, there is no if/else type syntax but you can run Javascript with

EVAL("Javascript code here")

If anyone knows how I could do this I could really use the help

回答1:

You can trick Imacros to make an If statement, but first you have to SET !ERRORIGNORE YES for this macro. Then:

SET EXTRACT NULL 'if this exist you extract the text(even if you know it) 'if doesn't exist should return error but we turned that off; Extract remains Null TAG POS=1 TYPE=SMALL ATTR=TXT:follows<SP>you EXTRACT=TXT SET !VAR1 EVAL("var text=\"{{!EXTRACT}}\"; if(text==\"follows you\") text = \"jibber\";else text = \"UnFollow\";text;") 'this one executes if the text is right, if not should give error but we turned that off TAG POS=1 TYPE=DIV ATTR=TXT:{{!VAR1}}

Use a javascript file for this

run(); function run() {   var exists = doesElementExist();   alert('element exists? ' + exists);   if (exists) {     iimPlay('CODE: TAG POS=1 TYPE=DIV ATTR=TXT:UnFollow');   }   else {     // do something else here   } }  // test if element exists function doesElementExist() {   iimDisplay('looking for small element with class "follow-status" on page');   var code = iimPlay('CODE: SET !TIMEOUT_TAG 1\n'                      + 'TAG POS=1 TYPE=SMALL ATTR=CLASS:follow-status EXTRACT=TXT');   if (code !==1) {     return false;   }   var extract = iimGetLastExtract();   if (extract === '#EANF#') {     return false;   }   return true; }
