如何在頁面上發現元素時播放代碼

如果在網頁上找到變量「組」中的元素，則應執行播放代碼。如果沒有，那麼它應該讓瀏覽器回到上一頁。這個if語句應該如何正確實施？如何在頁面上發現元素時播放代碼

var group = 'TAG POS=1 TYPE=TEXTAREA ATTR=ID:"post_field"'; 

if(opengroup) { 
     iimPlayCode('SET !REPLAYSPEED FAST\nADD !EXTRACT {{!URLCURRENT}}\nSAVEAS TYPE=EXTRACT FOLDER=* FILE=url.txt ') 
    } else { 
     iimPlayCode('URL GOTO=javascript:window.content.history.back()'); 
    }

這可以幫助：

var opengroup = iimPlayCode("SET !TIMEOUT_STEP 0" + "\n" + 'TAG POS=1 TYPE=TEXTAREA ATTR=ID:"post_field"'); 
if (opengroup == 1) 
    iimPlayCode('SET !REPLAYSPEED FAST\nADD !EXTRACT {{!URLCURRENT}}\nSAVEAS TYPE=EXTRACT FOLDER=* FILE=url.txt ') 
else 
    iimPlayCode('URL GOTO=javascript:window.content.history.back()');

我猜你想創建一個if語句。這可以通過使用EVAL將java轉換爲iMacros來實現，這裏是我使用過的一個例子：

URL GOTO=https://en.wikipedia.org/wiki/Main_Page 
WAIT SECONDS=1 

'Set the VAR1 to the current url= https://en.wikipedia.org/wiki/Main_Page 
SET !VAR1 {{!URLCURRENT}} 
WAIT SECONDS=1 
URL GOTO=https://en.wikipedia.org/wiki/Portal:Featured_content 
WAIT SECONDS=1 

'Set the VAR2 to the current url= https://en.wikipedia.org/wiki/Portal:Featured_content 
SET !VAR2 {{!URLCURRENT}} 

' 1.Now !VAR3 is our answer from the if statement 
' 2.We need to assign the text from {{!VAR1}} to a var x,y,z,... 
'  In this case, we use the letter d and s, and assign text with \"....\" to the var 
' 3.We check if d and s are equal by if (d==s), there is also not equal (d!=s) 
'  Or bigger(but only for numbers) (d>s) or smaller (d<s) 
' 4.After the if we say what !VAR3 should become if the if statement is right 
'  This is done by creating a new var (in this case the x) 
'  However the output shall be again a text, so we assign x to https://www.google.de 
'  And do this by assigning text to a var with \"....\"  so in this case {var x = \"https://www.google.de\";} 
' 5.After that we add the else, if the statement was false, and assign x to the text, which should 
'   !Be VAR3 when the statement was wrong, and we do this again the same way  so in this case {var x=\"https://www.youtube.com\";} 
'  6. At the end we "call" x and tell that whatever x has become, it is now !VAR3 

SET !VAR3 EVAL("var d=\"{{!VAR1}}\"; var s=\"{{!VAR2}}\" ; if (d==s){var x = \"https://www.google.de\";} else {var x=\"https://www.youtube.com\";} x;") 

'checking if code worked (and it did) 
URL GOTO={{!VAR3}} 

'you can of course change the SET !VAR1 or !VAR2 to some text inside a page, or whatever you like
