我从这个问题中了解到这个问题；答：Update widget form after drag-and-drop (WP save bug).
我是answering a Stack Overflow question 面临同样的问题。我们必须添加AjaxComplete 行动并启动我们的功能XMLHttpRequest.responseText 是真的。我不确定内部工作，但我们只需修改以下代码中的一行（通过onetrickpony):
// https://wordpress.stackexchange.com/a/37707
jQuery( document ).ajaxComplete( function( event, XMLHttpRequest, ajaxOptions ) {
// determine which ajax request is this (we\'re after "save-widget")
var request = {}, pairs = ajaxOptions.data.split(\'&\'), i, split, widget;
for( i in pairs ) {
split = pairs[i].split( \'=\' );
request[decodeURIComponent( split[0] )] = decodeURIComponent( split[1] );
}
// only proceed if this was a widget-save request
if( request.action && ( request.action === \'save-widget\' ) ) {
// locate the widget block
widget = jQuery(\'input.widget-id[value="\' + request[\'widget-id\'] + \'"]\').parents(\'.widget\');
// trigger manual save, if this was the save request
// and if we didn\'t get the form html response (the wp bug)
if( !XMLHttpRequest.responseText )
wpWidgets.save(widget, 0, 1, 0);
// we got an response, this could be either our request above,
// or a correct widget-save call, so fire an event on which we can hook our js
else
jQuery(\'DO_OUR_STUFF\');
}
});
演示插件
<?php
/* Plugin Name: Demo Widget jQuery Damit */
add_action( \'widgets_init\', \'b5f_load_widgets\' );
function b5f_load_widgets() {
register_widget( \'B5F_Example_Widget\' );
}
class B5F_Example_Widget extends WP_Widget {
private $url;
function B5F_Example_Widget() {
$this->url = plugins_url( \'/test-me.js\', __FILE__ );
$widget_ops = array( \'classname\' => \'example\', \'description\' => \'\' );
$control_ops = array( \'width\' => 300, \'height\' => 350, \'id_base\' => \'example-widget\' );
$this->WP_Widget( \'example-widget\',\'Example Widget\', $widget_ops, $control_ops );
if( is_admin() )
wp_enqueue_script( \'test-me\', $this->url, array(), false, true );
}
function widget( $args, $instance ) {
echo \'Test\';
}
function update( $new_instance, $old_instance ) {
return $instance;
}
function form( $instance ) {
echo "<a href=\'#\' class=\'test-me\'>File to load: {$this->url}</a>";
}
}
和onetrickpony的代码适应了我们的小部件(
/wp-content/our-plugin/test-me.js):
// Common function to do the Trick and our jQuery action
function test_click() {
var number = 1 + Math.floor( Math.random() * 5000000 );
jQuery( this ).html( \'WordPress Answers #\' + number );
}
// Our jQuery
jQuery( document ).ready( function( $ ) {
$( \'.test-me\' ).click( test_click );
});
// OneTrick\'s
// https://wordpress.stackexchange.com/a/37707
jQuery( document ).ajaxComplete( function( event, XMLHttpRequest, ajaxOptions ) {
var request = {}, pairs = ajaxOptions.data.split(\'&\'), i, split, widget;
for( i in pairs ) {
split = pairs[i].split( \'=\' );
request[decodeURIComponent( split[0] )] = decodeURIComponent( split[1] );
}
if( request.action && ( request.action === \'save-widget\' ) ) {
widget = jQuery(\'input.widget-id[value="\' + request[\'widget-id\'] + \'"]\').parents(\'.widget\');
if( !XMLHttpRequest.responseText )
wpWidgets.save(widget, 0, 1, 0);
else
jQuery( \'.test-me\' ).click( test_click ); // <--- One trick, pony!
}
});
