我想在JS中获取stylesheet_directory，但无法让它工作。
以下是我的尝试：
url : '<?php bloginfo('stylesheet_directory'); ?>/img/hamburger.svg'
和
var stylesheetDir = "<?php bloginfo('stylesheet_directory') ?>";
url : '$stylesheetDir/img/hamburger.svg',
我猜某些角色或其他东西只有问题？你能帮帮我吗？
svgicons-CONFIG-JS
var stylesheetDir = "<?php bloginfo('stylesheet_directory') ?>";
url == $stylesheetDir;
decodeURI(url);
var svgIconConfig = {
hamburgerCross : {
url : stylesheetDir + '/img/hamburger.svg',
animation : [
{
el : 'path:nth-child(1)',
animProperties : {
from : { val : '{"path" : "m 5.0916789,20.818994 53.8166421,0"}' },
to : { val : '{"path" : "M 12.972944,50.936147 51.027056,12.882035"}' }
}
},
{
el : 'path:nth-child(2)',
animProperties : {
from : { val : '{"transform" : "s1 1", "opacity" : 1}', before : '{"transform" : "s0 0"}' },
to : { val : '{"opacity" : 0}' }
}
},
{
el : 'path:nth-child(3)',
animProperties : {
from : { val : '{"path" : "m 5.0916788,42.95698 53.8166422,0"}' },
to : { val : '{"path" : "M 12.972944,12.882035 51.027056,50.936147"}' }
}
}
]
},
};
hamburger_animation.js

请检查元素（或类似），并查看代码“无法加载资源：服务器响应状态为404（未找到）”
答案 0 :(得分：6)
而不是：
url : '$stylesheetDir/img/hamburger.svg',
使用
url : stylesheetDir + '/img/hamburger.svg',
修改
因此，以下代码已过时且不必要（它什么都不做，可以删除）：
url == $stylesheetDir;
decodeURI(url);
随意删除它。除此之外一切都很好。
我想还需要一些代码。您应该了解自己如何使用svgIconConfig变量，特别是url属性。
编辑
感谢您透露更多代码。您似乎在JS文件中调用<?php ... ?>块。服务器不会解析此块，因此直接显示该块而不是将URL呈现给主题。
我不确定您是如何将代码排入队列的，因此我建议使用适用于任何用例的解决方案。
要解决此问题，请在主题functions.php
中插入以下内容add_action('wp_head', 'my_js_var_stylesheet_directory', 9);
function my_js_var_stylesheet_directory() {
echo '<script type="text/javascript">';
echo 'var stylesheetDir = "' . get_bloginfo('stylesheet_directory') . '"';
echo '</script>';
}
并删除svgicons-config-js文件中的前3行，因为它们是不必要的。
答案 1 :(得分：1)
从您的代码中，您必须回显css目录的路径。
检查一下：
var stylesheetDir = '<?php echo loginfo('stylesheet_directory') ; ?>/img/hamburger.svg';
console.log(stylesheetDir);
