如何使用javascript将innerText转换为php函数

// 获取元素的innerText
var element = document.getElementById("exampleElement");
var innerText = element.innerText;

// 将innerText传递给PHP函数
var phpFunctionUrl = "example.php"; // 替换为你的PHP函数的URL
var xhr = new XMLHttpRequest();
xhr.open("POST", phpFunctionUrl, true);
xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xhr.onreadystatechange = function() {
  if (xhr.readyState === 4 && xhr.status === 200) {
    // 处理PHP函数的返回结果
    var result = xhr.responseText;
    console.log(result);
  }
};
xhr.send("innerText=" + encodeURIComponent(innerText));
