iMacros iimGetExtract()

Question

我是JavaScript的新手，我需要一些帮助从iMacros中获得最后的提取值。问题是，当我使用JavaScript函数alert()时，它显示了正确的最后提取，但是如果条件不起作用的话。

宏步骤：

1. 单击基于循环定位的图像
2. 点击按钮，如果有文本，提取文本，如果文本是2，启动另一个iim代码。代码更复杂，这只是提取调试的一部分，这对于启动另一段代码的条件词很重要。

我得到的错误是：

TypeError:路径未定义，行-633 (错误代码：-991)

以下是代码：

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;
    }
 }

我检查了代码中的问题，发现它在下面的块中失败了。

else {iimPlay(goToProductUrl);}

因为goToProductUrl变量是在if条件下定义的。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而无法检查程序工作，但其他块是否应该是这样的呢？

else {iimPlay(macroStart);}

javascript错误已修复，请尝试在删除错误后构建代码。

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;
    }
 }
