iMacros iimGetExtract（）

Question

我是JavaScript新手，我需要一些帮助，从iMacros获取最后提取的值。问题是，当我使用JavaScript函数alert()时，它显示正确的最后提取，但如果条件不起作用。宏

步骤：

1. Click on image which is positioned based on LOOP

2. Click on button and if there exists a text, extract the text and if text is 2 start another iim code. The code is more complex, this is only part for extract debug which is important for conditionals which starts another piece of code

我得到的错误是：

TypeError: path is undefined, line -633 (Error code: -991)

下面是代码：

var numPage = prompt("current numPage?"); 
numPage++; 
var i = 1; 
var macroStart; 
macroStart = "CODE:"; 
macroStart += "'set global variables" + "\n"; 
macroStart += "SET !EXTRACT_TEST_POPUP NO" + "\n"; 
macroStart += "SET tabCheck NULL" + "\n"; 
macroStart += "SET !ERRORIGNORE YES" + "\n"; 
macroStart += "SET !EXTRACT NULL" + "\n"; 
macroStart += "SET !TIMEOUT_STEP 1" + "\n"; 
macroStart += "SET !CLIPBOARD NULL" + "\n"; 
macroStart += "SET productUrl {{!URLCURRENT}}" + "\n"; 
macroStart += "TAG POS={{i}} TYPE=IMG ATTR=SRC:https://www.xxx.sk/admin/xxx/xxx/img/uprav.gif" + "\n"; 
macroStart += "TAG POS=1 TYPE=A ATTR=ID:zalozka_obrazky" + "\n"; 
macroStart += "TAG POS=1 TYPE=A ATTR=TXT:2 EXTRACT=TXT" + "\n"; 

macroStartExtract = iimGetLastExtract(); 
if (macroStartExtract == 2) { 
    var goToProductUrl; 
    goToProductUrl += "'back to main product's page" + "\n"; 
    goToProductUrl += "SET !VAR5 2" + "\n"; 
    goToProductUrl += "PROMPT !VAR5" + "\n"; 
    iimPlay(goToProductUrl); 
    } else {iimPlay(goToProductUrl);} 


var macroChangePage; 
macro2 = "CODE:" 
macro2 += "TAG POS=2 TYPE=A ATTR=TXT:{{numPage}}" 

while (i < 2) { 
    iimSet("i",i) 
    iimPlay(macroStart) 
    i++; 

    if (i == 2) { 
     iimSet("numPage", numPage) 
     iimPlay(macroChangePage) 
     numPage++ 
     i = 1; 
    } 
}

我检查，出现问题的代码，我发现它在下面的块中失败。

else {iimPlay(goToProductUrl);} 

由于goToProductUrl变量在if条件中得到了定义。 if没有被执行，当它进入else块时，变量是未定义的，因此程序失败。由于缺少URL而无法检查程序是否工作，但是如果else块是这样的？

else {iimPlay(macroStart);} 

javascript错误已修复，请在删除错误后尝试构建代码。

var numPage = prompt("current numPage?"); 
numPage++; 
var i = 1; 
var macroStart; 
macroStart = "CODE:"; 
macroStart += "'set global variables" + "\n"; 
macroStart += "SET !EXTRACT_TEST_POPUP NO" + "\n"; 
macroStart += "SET tabCheck NULL" + "\n"; 
macroStart += "SET !ERRORIGNORE YES" + "\n"; 
macroStart += "SET !EXTRACT NULL" + "\n"; 
macroStart += "SET !TIMEOUT_STEP 1" + "\n"; 
macroStart += "SET !CLIPBOARD NULL" + "\n"; 
macroStart += "SET productUrl {{!URLCURRENT}}" + "\n"; 
macroStart += "TAG POS={{i}} TYPE=IMG ATTR=SRC:https://www.xxx.sk/admin/xxx/xxx/img/uprav.gif" + "\n"; 
macroStart += "TAG POS=1 TYPE=A ATTR=ID:zalozka_obrazky" + "\n"; 
macroStart += "TAG POS=1 TYPE=A ATTR=TXT:2 EXTRACT=TXT" + "\n"; 

macroStartExtract = iimGetLastExtract(); 
if (macroStartExtract == 2) { 
    var goToProductUrl; 
    goToProductUrl += "'back to main product's page" + "\n"; 
    goToProductUrl += "SET !VAR5 2" + "\n"; 
    goToProductUrl += "PROMPT !VAR5" + "\n"; 
    iimPlay(goToProductUrl); 
    } else {iimPlay(macroStart);} 


var macroChangePage; 
macro2 = "CODE:" 
macro2 += "TAG POS=2 TYPE=A ATTR=TXT:{{numPage}}" 

while (i < 2) { 
    iimSet("i",i) 
    iimPlay(macroStart) 
    i++; 

    if (i == 2) { 
     iimSet("numPage", numPage) 
     iimPlay(macroChangePage) 
     numPage++ 
     i = 1; 
    } 
}
