javascript - 将数据ajax发送到php

Question

我想在点击删除时发布该值。请检查错误

$.ajax({
         type: "POST",
         var checkid =  $('#delete').click(function(){ $(this).val();});,
         url: "survey-command.php",
         data: { checkid: checkid, }
            }).done(function( msg ) {
                alert( "Data Saved: " + msg );
       });  

我不知道如何将值传递给这个 checkid 变量

Answer 1

我认为你的代码应该如下所示:

$('#delete').click(function(){
   var checkid= $(this).val(); //assuming $('#delete') is an input.
                               // otherwise use $('#delete').html();
    $.ajax({
         type: "POST",
         url: "survey-command.php",
         data: { checkid: checkid, }
            }).done(function( msg ) {
                alert( "Data Saved: " + msg );
       }); 
 });
