使用javascript将数据（$ post）传递给php文件，无需回调

I need to pass data from HTML page to PHP page But without data callback ....

i'm used two method but One of them did not succeed

1)

$.ajax({
    type: "POST",
    url: 'phpexample.php',
    data: {voteid: x },
    success: function(data)
    {
        alert("success! X:" + data);
    }
});

2)

$.post("getClassStudent.php",
{
},
function(data){
    $("#div_id.php").html(data);

    }
);

as i can understand, you just want to send info to a php script and don't need the response, is that right?

try this

$.post("phpexample.php", {voteid:x});

or simply remove the "succes" function from the equation if you feel more confortable using $.ajax instead of $.post

$.ajax({
    type: "POST",
    url: 'phpexample.php',
    data: {voteid: x }
});

your fisrt example is correct, the second is not well formed.

EDIT: to help you some more :)

<button type="button" id="element-id">click</button>

<button type="button" class="class-name">Click</button>

$(document).ready(function(){ 
    //if you are marking ans element by class use '.class-name'
    $(".class-name").click(function(){ 
       $.post("getClassStudent.php"); 
    }); 
    //if marking by id element use '#id-name'
    $("#element-id").click(function(){ 
       $.post("getClassStudent.php"); 
    }); 
});

be carefful with the markings, for debuggin try to use "console.log()" or "alert()" so you can see where is the problem and where the code crushes.

var formData = {
  'voteid'              : 'x',
};
$.ajax({
    type        : 'POST', 
    url         : 'phpexample.php', 
    data        : formData, // our data object
    dataType    : 'json', 
    encode      : true
 }).done(function(data) {
    console.log(data);
 });
