问题描述
我使用以下WordPress管理通知提示用户下载一些文件。我想在文件下载时包含一个进度条或至少一个下载 - 请稍候的消息。
I use the following WordPress admin notice to prompt users to download some files. I would like to include either a progress bar or at least a "Downloading - Please wait" message while files are downloading.
任何想法?
我已经尝试过几个jQuery解决方案,但可以无所事事。在jQuery中我总是noob。
I've tried several jQuery solutions but could get nothing to work. I'm a total noob when it comes to jQuery.
/* Ask user to download GeoIP database files. */
add_action( 'admin_notices', 'lsmi_dl_admin_notice' );
add_action( 'network_admin_notices', 'lsmi_dl_admin_notice' ); // also show message on multisite
function lsmi_dl_admin_notice() {
$dir = dirname( __FILE__ );
$localfilev4 = $dir . '/data/GeoIPv4.dat';
$localfilev6 = $dir . '/data/GeoIPv6.dat';
$ctx = stream_context_create( array( 'http' => array( 'timeout' => 120 ) ) );
if ( !file_exists( $localfilev4 ) ) {
if ( current_user_can( 'install_plugins' ) ) {
echo
'<div class="notice notice-warning is-dismissible"><p>Notice: This plugin uses Maxmind Geolite databases for better accuracy. Click the download button to install now.
<form action="" method="get">
<input type="submit" class="button" name="download" value="download" />
</div>';
if($_GET){
if(isset($_GET['download'])){
$newfilev4 = file_get_contents( "https://sourceforge.net/projects/geoipupdate/files/GeoIPv4.dat/download", 0, $ctx );
file_put_contents( $dir . '/data/GeoIPv4.dat', $newfilev4 );
if ( !file_exists( $localfilev6 ) ) {
$newfilev6 = file_get_contents( "https://sourceforge.net/projects/geoipupdate/files/GeoIPv6.dat/download", 0, $ctx );
file_put_contents( $dir . '/data/GeoIPv6.dat', $newfilev6 );
}
}
echo '<meta http-equiv="refresh" content="0">';
}
}
}
}
推荐答案
尝试给你的按钮一个这样的ID:
Try giving your button an ID like so:
<input type="submit" class="button" name="download" value="download" id="download" />
还给你的div这样的id:
Also give your div an id like so:
<div class="notice notice-warning is-dismissible" id="download-div">
然后我们可以使用一个基本的jQuery onClick函数,并改变's innerhtml,如下所示:
Then we can use a basic jQuery onClick function and change the 's innerhtml like so:
$("#download").click(
function () {
$('#download-div').html("Please wait...");
}
);
});
希望这有助于:)
