Question

如何将其转换为 JQuery？

function contantForm()
{
    let Username = document.getElementById("Username").value;  //create element Id called Username
    let Emailinput = document.getElementById("Email").value; //create element Id called Emailinput
    alert("Thank you " + Username) //alerts user with thier username after clicking submit
    document.getElementById("Username").value=""; //get username Id from index page
    document.getElementById("Email").value=""; //get email Id from index page
    document.getElementById("Phone").value=""; //get phone Id from index page
}

谢谢，

纯 JS 和 Jquery 可以一起工作，您的代码在有或没有 jquery 的情况下都可以工作，但是如果您希望所有代码格式相同。

 function contantForm() { let Username = $("#Username").val(); let Emailinput = $("#Email").val(); alert("Thank you " + Username) $("#Username").val(""); $("#Email").val(""); $("#Phone").val(""); }
