我正在尝试编写一个插件来显示RunKeeper Healthy button 但当我查看页面源代码时，我的输出有额外的空间和双引号。我试图用这个按钮通过内联JavaScript打开一个新窗口。

我尝试在单引号和双引号之间切换，并确保正确转义嵌套引号。正在尝试附加get_permalink() 断开RunKeeper共享URL的生成链接。链接本身的图像标记很好，但当我将鼠标悬停在上面时，我看到一个不完整的链接。

链接输出为：

<a href="javascript:void(window.open(\'http://runkeeper.com/share?healthyUrl=http://my_website/my_post_permalink/ " , \'\' , \'width=630,height=350\');">

但我所期望的是：

<a href="javascript:void(window.open(\'http://runkeeper.com/share?healthyUrl=http://my_website/my_post_permalink/\' , \'\' , \'width=630,height=350\');">

到目前为止，我的插件代码是这样的：

add_filter(\'the_content\', \'add_runkeeper_btn\' );

function add_runkeeper_btn($content) {
    $output = "";

    if (is_single()) {
        $output .= "<a href=\\"javascript:void(window.open(\'http://runkeeper.com/share?healthyUrl=";
        $output .= get_permalink();
        $output .= "\', \'\' , \'width=630,height=350\');\\">";
        $output .= "<img src=\\"http://runkeeper.com/static/kronos/images/HealthyButton.png\\" class=\\"healthyImage\\" alt=\\"RunKeeper Healthy Button\\" />";
        $output .= "</a>";
    }

    return $output . $content;
}

作为参考，这是RunKeeper博客文章的页面源中的内容。我正在尝试修改它，以便healthyUrl 查询参数引用帖子的永久链接。

<a href="javascript:var%20d=document,l=d.location;void(window.open(\'http://runkeeper.com/share?healthyUrl=\'%20+%20l.href,\'\',\'width=630,height=350\'));">
    <img src="http://runkeeper.com/static/kronos/images/HealthyButton.png" class="healthyImage" alt="RunKeeper Healthy Button">
</a>

function add_runkeeper_btn($content) {
    if (is_single()) {
        echo \'<p><a href="javascript:void(window.open(\\\'http://runkeeper.com/share?healthyUrl=\';
        echo trim(get_permalink());
        echo \'\\\', \\\'\\\', \\\'width=630,height=350\\\'));">\';
        echo \'<img src="http://runkeeper.com/static/kronos/images/HealthyButton.png" class="healthyImage" alt="RunKeeper Healthy Button" />\';
        echo \'</a></p>\';
    }

    return $content;
}

<a href="javascript:void(window.open(\'http://runkeeper.com/share?healthyUrl=http://my_website/my_post_permalink/ " , \'\' , \'width=630,height=350\');">
                                                                                                               ^^^^^
