Question

我写了一篇Grease Monkey的文章,在博客中添加一个纽子。我已提醒大家,我知道一切都在进行。

The strange thing is that it fires twice, slightly differently each time. When I navigate to a blogger.com post edit, the script fires first on a black page and goes through all of the alerts in the right order including the "inside" one.

排在页数之后的第二段,除“侧面”外,每一次警报都发生,没有产生错误。

 // ==UserScript==
 // @name  Blogger: Remove HTML Space
 // @include  http://www.blogger.com/blogger.g?blogID*editor/target*
 // ==/UserScript=

 function contentEval(source) {
   // Check for function input.
   alert("asdas");
   if ( function  == typeof source) {
     // Execute this function with no arguments, by adding parentheses.
     // One set around the function, required for valid syntax, and a
     // second empty set calls the surrounded function.
     source =  (  + source +  )(); 
   }

   alert("asdas2");
   // Create a script node holding this  source code.
   var script = document.createElement( script );
   alert("asdas3");
   script.setAttribute("type", "application/javascript");
   alert("asdas4");
   script.textContent = source;
   alert("asdas5");

   // Insert the script node into the page, so it will run, and immediately
   // remove it to clean up.
   alert("asdas6");
   document.body.appendChild(script);
   alert("asdas7");
 }

  alert("test")
  contentEval(function(){ alert("inside"); document.getElementById("postingHtmlToolbar").firstChild.innerHTML +=  <div id="SP" class="goog-inline-block goog-toolbar-button" title="SP" role="button" style="-moz-user-select: none;"><div class="goog-inline-block goog-toolbar-button-outer-box"><div class="goog-inline-block goog-toolbar-button-inner-box"><button type="button" onclick="document.getElementById( postingHtmlBox ).value = document.getElementById( postingHtmlBox ).value.replace(/&amp;nbsp;/g,    );"><b>SP</b></button></div></div></div> });

 alert("testw");

blogger.com有抗药注射吗?

www.un.org/Depts/DGACM/index_spanish.htm 大约两次发射:

如果该网页包含<iframe>s,用户代码将各自发射。

您需要确定您是否在<代码>和>、iframe>、内。只有在主页,而不是金字塔,才最简单的火力方式是用以下方式包罗所有代码:

if(top==self)
{
  ...
}

参看<iframe>s in the page (要么是硬编码,要么是动态生成的) 我总是使用AdBlock Plus(“可阻挡物品”)方言。

I m not sure however why the second "inside" alert does not launch. I ve created a simple HTML page containing <iframe> and I get two alerts fired.

www.un.org/Depts/DGACM/index_spanish.htm 描述一般:

你在此重复工作。你们无需包罗一切,才能执行文字。 Greasemonkey在页面负荷后(DOMContent Loaded)执行代码项目。因此,你不必创建<代码><script> tag,将其体质和附着文件。你可以说,

document.getElementById(“postingHtmlToolbar”).firstChild.inner/60/8 += ......

and it should do what you want (you don t need contentEval function at all).

我在博客上没有任何博客,因此,我可以记录和看到任何URL和有问题的行为,但按部就班行事,这应足以缓解。

<><>><>>>>

Seems that You should change firstChild to firstElementChild。




firstChild returns Node
firstElementChild returns Element.


There is innerHTML property in Element (since Firefox 3.5), but not in Node. 
Yeah, it s really inconsistent and annoying at times. I ve come into similar problem recently.

那里有两件事。 请不要告诉我,它没有做什么工作:

var func = function() {
    var obj = document.getElementById("postingHtmlToolbar");
    if(obj !== null){ // only if object exists, so we don t have errors
       //alert(obj);
       obj.style.display =  block ; // it s hidden by default
       obj.firstElementChild.innerHTML += "FOO";
    }
 }

 window.setTimeout(func, 3000); // execute with delay -- let s give Google s JS time to be loaded first

全球机制可以直接修改一个网页,使全球机制发挥效用。

The <button> tag... don t You mean INPUT?

我认为,由于采用这种方法,我猜测你的工作是无法直接修改这一页。

你们要做的是,你重新创设了名词功能,如果你在联合材料中不曾经历过这种功能,那么“我们”就是这样做的。这将是一个问题:

if ( function  == typeof source) {
   // Execute this function with no arguments, by adding parentheses.
   // One set around the function, required for valid syntax, and a
   // second empty set calls the surrounded function.
   source =  (  + source +  )(); 
}

当你在+你之间设立“智囊团”时,你将这一职能称为“你”,因为你重新召集,而且作为一种职能并非一种扼杀,当时正在试图胁迫它,因为它履行这一职能,但最后是空洞()再次执行,后来又不执行。我没有试过,但我确实认为正在发生。

因此,jakub正确地指出,你的法典的复杂性是不必要的,归根结底是给你留下错误。
