我有一个wordrpess网站,我正在尝试执行ajax调用来发送变量,但是当我尝试检索变量时我无法使其工作我没有得到任何回报这是我的代码:
<script type="text/javascript">
window.onload = function(){
var boton = document.getElementsByClassName("teatro-buy");
const xhr = new XMLHttpRequest();
xhr.onload = function ()
{
console.log(this.responseText);
}
for (let qq = 0; qq < boton.length; qq++)
{
boton[qq].onclick = function()
{
botonid = this.id ;
xhr.open("POST", "ajaxcallnew.php")
xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhr.send("lol=" + botonid);
console.log(botonid);
}
}
};
</script>
这是我的php
<?php
if(isset($_POST['lol'])){ //check if $_POST['examplePHP'] exists
echo $_POST['lol']; // echo the data
die(); // stop execution of the script.
}
?>

检查您的格式:
的示例:
(1)得到:
var ajax = new XMLHttpRequest();
ajax.open('get','getStar.php?starName='+name);
ajax.send();
xhr.onreadystatechange = function () {
if (xhr.readyState == 4 && xhr.status == 200) {
console.log(xhr.responseText);
}
};
(2)发布:
var xhr = new XMLHttpRequest();
xhr.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xhr.open('post', '02.post.php' );
xhr.send('name=fox&age=18');
xhr.onreadystatechange = function () {
if (xhr.readyState == 4 && xhr.status == 200) {
console.log(xhr.responseText);
}
};

您必须添加到您的请求操作属性。
例如:
jQuery.ajax({
url: ajaxurl, // ('admin-ajax.php')
method: 'POST',
dataType: 'json',
data: {action: 'yourvalue', fields: info},
success: function (json) {
console.log(json)
});
并在functions.php
上添加以下内容:
add_action('wp_ajax_nopriv_actionValue', 'FunkName');
add_action("wp_ajax_actionValue", 'FunkName');
function FunkName()
{
//buisness logic
}

为什么不使用jQuery呢?它会变得非常简单。
$.ajax({
url:'path_to_php_file.php',
type:'post',
data:{'lol':'value_for_lol'},
onsuccess:function(response){
alert(response);
}
});
