Greasemonkey腳本在使用AJAX提交時將文本追加到表單中？

Question

因此，我正在爲mybb論壇製作Greasemonkey腳本。它的作用是當你提交一篇文章時，它會在文章的開頭和結尾添加代碼。即使那麼這是一個不好解釋只是看看代碼，它解釋了自己

function form_submit(event) { 
var form = event ? event.target : this; 
    var arTextareas = form.getElementsByTagName('textarea'); 
    for (var i = arTextareas.length - 1; i >= 0; i--) { 
     var elmTextarea = arTextareas[i]; 
     elmTextarea.value = "[font=Tahoma][color=white]" + elmTextarea.value + "[/color][/font]"; 
    } 

    form._submit(); 
} 

window.addEventListener('submit',form_submit, true); 
HTMLFormElement.prototype._submit = HTMLFormElement.prototype.submit; 
HTMLFormElement.prototype.submit = form_submit; 

現在作品無處不在，我希望它除了quickreply發表回覆按鈕。我假設這是因爲quickreply按鈕使用AJAX提交表單，頁面不會重新加載。

所以我想知道我該怎麼做，所以當我點擊quickreply按鈕它附加我想要的文字。我已經尋找了一段時間和任何我能找到沒有工作

而且，這裏是一個使用AJAX（不與上面的代碼工作的按鈕）

<input id="quick_reply_submit" class="button" type="submit" accesskey="s" tabindex="2" value="Post Reply"> 

按鈕的代碼

這裏是所在

您需要向我們展示本身到該按鈕關聯的JavaScript。如果它採用AJAX技術，那麼只有這樣才能知道它在做什麼。

這就是說，這段代碼將可能工作：

function form_submit (event) { 

    var form, bClickNotSubmit; 

    if (event && event.type == 'click') { 
     bClickNotSubmit = true; 
     form   = document.getElementById ('quick_reply_form'); 
    } 
    else { 
     bClickNotSubmit = false; 
     form   = event ? event.target : this; 
    } 

    var arTextareas = form.getElementsByTagName ('textarea'); 

    for (var i = arTextareas.length - 1; i >= 0; i--) { 
     var elmTextarea  = arTextareas[i]; 
     elmTextarea.value = "[font=Tahoma][color=white]" + elmTextarea.value + "[/color][/font]"; 
    } 

    if (! bClickNotSubmit) { 
     form._submit(); 
    } 
} 

window.addEventListener ('submit', form_submit, true); 
document.getElementById ('quick_reply_submit').addEventListener ('click', form_submit, true); 

HTMLFormElement.prototype._submit = HTMLFormElement.prototype.submit; 
HTMLFormElement.prototype.submit = form_submit; 

如果它不工作，目標頁面（完整的HTML，JS，CSS）保存到磁盤，壓縮文件一起分享郵編 - 這樣我們就可以看到該按鈕發生了什麼。
