【问题描述】：
我正在为与 UPS、USPS 和 FEDEX 通信的客户端开发 WP 插件。 USPS 需要多个步骤，因此我使用 UI 对话框模式，在其中通过 AJAX (PHP) 动态添加内容。内容很棒，但似乎当我单击第一个对话框上的继续按钮时，它会触发所有连续的对话框按钮功能。我调用了一个函数来更改对话框内容，每个调用函数都发送 AJAX 数据并设置下一个对话框的选项。我需要该按钮来简单地完成其功能并允许用户在下一个对话框中进行选择。虽然我使用 JQuery、JS 和 PHP 已经有一段时间了，但我对 jQuery UI 还是很陌生。请参阅下面的代码以供参考。对此的任何帮助将不胜感激。
“obj”是一个从 PHP 返回的对象，其中包含发货数据和用于对话框的 html。
更新对话内容的功能
show_dialog = function( title, html, options ) {
$( "#dialog" ).dialog({
autoOpen: false,
});
$('#dialog').html( html );
$('#dialog').dialog( 'option', 'title', title );
$('#dialog').dialog( options );
$('div.ui-dialog-buttonset button.ui-button span.ui-button-text').each(function() {
$(this).html($(this).parent().attr('text'));})
}
地址验证功能
usps_address_check = function( obj ) {
if( obj.VStatus === 'AddressMatch' ) {
var title = obj.Title;
var options = {
resizable: false,
width:800,
modal:true,
buttons: {
//when this button is clicked it fires the function in the next dialog below process shipment.
'Continue': function(event) {
if( $('#verified').attr('checked') ) {
data = {
action: 'usps_ajax',
call: 'check_rate',
post: $('#post_id').val(),
};
ajax_request( data );
} else {
$(this).dialog( 'option', 'title', "Please click the checkbox to confirm corrected address..." );
}
},
Cancel: function() {
$(this).dialog( 'close' );
}
}
}
}
show_dialog( title, obj.StatusMessage, options );
$('#dialog').dialog('open');
}
在处理 USPS 的发货请求之前确认运费和选择服务插件的功能
usps_confirm_rates = function( obj ) {
var title = obj.Title;
var html = obj.StatusMessage;
var options = {
resizable: true,
width:800,
height:800,
modal:true,
buttons: {
//This function is fired when the button on the first modal above is clicked.
'Process Shipment': function() {
data = {
action: 'usps_ajax',
call: 'process_shipment',
post: $('#post_id').val(),
};
ajax_request( data );
},
'Cancel': function(e) {
$(this).dialog( 'close' );
}
}
}
show_dialog( title, html, options );
