问题描述

我想创建自己的Greasemonkey脚本，我最喜欢的目录列表网站）

问题是不是一切就名单对我有利，我检查了网站code和，因为它似乎，每个条目正在

现在，当它看来，我只有那些具有这种格式感兴趣的是：

 ＆LT; TR类=项目描述＆GT;
＆LT; TD合并单元格=6＆GT;
    ＆LT; D​​IV CLASS =项目说明-内＆GT;
        ＆LT; D​​IV CLASS =项目简介＆GT;
            ＆LT; p =类trunk8＆gt;这是一个条目和LT; / P＆GT;
        ＆LT; / DIV＆GT;
        ＆LT; D​​IV CLASS =项目验证＆GT;
            ＆LT;跨度类=verfied徽章＆GT; ＆LT; ~~~~~~~~~~本SPAN
                ＆LT;跨度类=货币符号＆GT; $＆LT; / SPAN＆GT;
                ＆LT;跨度类=图标，勾选＆GT;＆LT; / SPAN＆GT;
                验证
            ＆LT; / SPAN＆GT;
        ＆LT; / DIV＆GT;
        ＆LT; D​​IV CLASS =项目行动＆GT;
            ＆所述; A HREF =＃＆GT;
                ＆LT;按钮类=BTN＆GT; LOL＆LT; /按钮＆GT;
            ＆所述; / A＆GT;
        ＆LT; / DIV＆GT;
    ＆LT; / DIV＆GT;
＆LT; / TD＆GT;
＆LT; / TR＆GT;
 

正如你所看到的，存在＆LT;跨度类=verfied徽章方式＆gt; 触发它

我也希望在页面加载后的JavaScript程序这一点，因为该网站填充通过javascript表了。

我知道我没有在我的问题还没有完成，但如果有人可以只提供一个例子，可以带领我，那就够了。

非常感谢你！

解决方案

  $（文件）。就绪（函数（）{
    $（tr.project的细节）。每个（函数（）{
       VAR自我= $（本）;
       如果（self.find（span.verfied徽章）。长度== 0）
           self.remove（）;
    }）;}）;
 

I am trying to create my own greasemonkey script for my favorite directory listing site :)

The thing is not everything it list is beneficial to me, I inspected the website code and as it seems, each entry is under

Now, and as it seems, I am only interested with those which have this format:

<tr class="project-description">
<td colspan="6">
    <div class="project-desc-inner">
        <div class="project-synopsis">
            <p class="trunk8">This is an entry</p>
        </div>
        <div class="project-verification">
            <span class="verfied-badge"> <~~~~~~~~~~ THIS SPAN
                <span class="currency-symbol">$</span>
                <span class="icon-tick"></span>
                Verified
            </span>
        </div>
        <div class="project-actions">
            <a href="#">
                <button class="btn">LOL</button>
            </a>
        </div>
    </div>
</td>
</tr>

As you can see, the existence of <span class="verfied-badge"> triggers it.

I also wish that the javascript process this after the page loads, because the site populates the table via javascript too.

I know I haven't done in my problem yet, but if somebody can just provide an example that can lead me, that is enough.

Thank you very much!

解决方案

$(document).ready(function(){
    $("tr.project-details").each(function(){
       var self = $(this);
       if(self.find("span.verfied-badge").length==0)
           self.remove();
    });

});
