imacros - 如果 iMacros 页面中存在文本，请单击按钮

Question

我正在尝试将 iMacros 与 Firefox 一起使用，仅当页面上存在此代码时才单击取消关注按钮...

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

如果页面源中不存在上述内容，那么它将运行此 iMacros 代码...

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

根据我的阅读，没有 if/else 类型语法，但您可以运行 Javascript

EVAL("Javascript code here")

如果有人知道我该怎么做，我真的可以使用帮助

Answer 1

你可以欺骗 Imacros 来做一个 If 语句，但首先你必须SET !ERRORIGNORE YES为这个宏做。然后：

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}}

Answer 2

为此使用 javascript 文件

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;
}
