jquery-ui – jQueryUI .dialog(“close”)在ajax调用后不起作用

我使用jQueryUI的对话框与模态窗体选项打开一个弹出窗体。当用户单击按钮时，它将其输入提交到数据库，然后关闭对话框。一切都在工作，除非关闭对话框。 (手动关闭按钮的工作原理;它从PHP 数据库脚本返回后不会自动关闭，这是脚本代码(我试图加粗不行的行，显然你不能嵌入代码标签中的粗体) ，但线条被双星号包围，使其脱颖而出，这些不是实际代码的一部分！)

<script>

        var name = $( "#name" ),email = $( "#email" ),company = $( "#company" ),plate = $( "#plate"),allFields = $( [] ).add( name ).add( email ).add( company ).add( plate ),tips = $( ".validateTips" );
 
        function updateTips( t ) {
            tips
                .text( t )
                .addClass( "ui-state-highlight" );
            setTimeout(function() {

            });
    });
</script>

有任何想法吗？
EDITED添加 PHP 代码

<?PHP
include('../cfg/ez_sql.PHP');
include('../cfg/db_setup.PHP');
 
$err = false;
if (isset($_REQUEST['plate'])) {
 
    $raw = "INSERT INTO dot_plate_submissions (plate_code,plate_name,plate_company,plate_email) VALUES ('%s','%s','%s')";
    $clean = sprintf($raw,MysqL_real_escape_string($_REQUEST['plate']),MysqL_real_escape_string($_REQUEST['name']),MysqL_real_escape_string($_REQUEST['company']),MysqL_real_escape_string($_REQUEST['email']));
 
    //error_log("cleaned query: $clean");
 
   $db->query($clean);
}
else {
    $err = true;
}
 
if($err) {
    $return['error'] = true;
    $return['msg'] = "There was an error submitting your plate";
}
else {
    $return['error'] = false;
    $return['msg'] = "made it to PHP";
}
echo json_encode($return);
?>

所以即使错误是错误的，ajax调用仍然会收回两个数据。

解决方法

更改您的$ .ajax调用以包含上下文，所以$(this)在回调中有效：

$.ajax({
    type: "POST",context: $(this),success: function(returnData){
        if(returnData.error === false) {
            $( this ).dialog( "close" );
            } else {
                  alert("Error: "+returnData.msg);
            }
    }   
});
