首先，我知道有很多问题与这个问题有关。但问题是，它们都与jquery有某种关联。

但我的问题实现了普通javascript。

基本上，除了onselect（）之外，其他一切都正常工作。我无法获取附件的URL。

Here is the code.

var custom_uploader;

var uploadButton = document.getElementById(\'upload_logo_button\');

uploadButton.addEventListener("click", function(e) {
    e.preventDefault();

    if ( custom_uploader ) {
        custom_uploader.open();
        return;
    }

    custom_uploader  = wp.media.frames.file_frame = wp.media({
        frame: \'select\',
        title: \'Choose Image\',
        button: {
            text: \'Select Image\'
        },
        multiple: false
    });

    custom_uploader.onselect = function() {
        var attachment = custom_uploader.state().get(\'selection\').first().toJSON();
        console.log(attachment);
        var uploadLogoImage = document.getElementById("upload_image").innerHTML(attachment.url);
    }

    //Open the uploader dialog
       custom_uploader.open();
});

请有人告诉我为什么我无法获得图像的URL，即使图像成功上传到WP媒体。提前谢谢。如果有人需要更多信息，请随时询问。再次感谢。

custom_uploader.onselect = function() {
    var attachment = custom_uploader.state().get(\'selection\').first().toJSON();
    console.log(attachment);
    var uploadLogoImage = document.getElementById("upload_image").innerHTML(attachment.url);
}

custom_uploader.on( \'select\', function() {
    var attachment = custom_uploader.state().get(\'selection\').first().toJSON();
    console.log(attachment);
    var uploadLogoImage = document.getElementById("upload_image").innerHTML = attachment.url;
} );
