用iMacros和javascript检查html元素是否存在 [英] Check if html element exists with iMacros and javascript

问题描述

我想检查iMacros是否存在HTML元素。如果是这样，我想去一个URL。如果没有，我想去其他网址。

因为iMacros没有语句，所以我在iMacros的EVAL中使用了javascript。
这是处理javascript执行的行：
$ b $ $ $ $ $ $ $ $ $ $ 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;
）

*全部在一行，然后，我将重定向到

$ p $ URL GOTO = {{！VAR3}}


问题是在这两种情况下， VAR3被设置为'undefined'。

我在Firefox上尝试了几乎相同的JS代码，它似乎正在工作。

使用最新的Firefox和最新的iMacros版本的Windows 8。

谢谢

解决方案

  var macro; 
 
 macro =CODE：; 
 macro + =TAG POS = 1 TYPE = DIV ATTR = CLASS：some_class CONTENT = EVENT：MOUSEOVER; 
 
 var ret = null; 
 
 ret = iimPlay（宏）; 
 
 if（ret> 0）
 {
 // do something 
} 
 else 
 {
 // do something else 
 
 
 
 
 
 $ p这是你想要的脚本的基本模型。你只需要插入正确的图像代码。
 
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.
