使用AJAX动态更新数据库中的文本

您需要将数据与ajax请求一起包括在内，

data: {registration: registration, rowid: rowid},

并将类型设置为POST，因为在php端您要检索POST变量。

像这样…

function updateText(registration, rowid) { $.ajax({    //create an ajax request to readmessages.php     type: "POST",     url: "readmessages.php",       dataType: "html",   //expect html to be returned       data: {registration: registration, rowid: rowid},     success: function(response){   $("#responsecontainer").html(response);     }
