按钮单击事件多次触发

Question

所以这个按钮多次触发有问题。如果我点击一个按钮它工作正常（只发射一次），但如果我点击另一个按钮后，它会发射两次，依此类推。我尝试了.of（“click”），$（this）.unbind（）和.one（“click”，function（）{}）方法，但它们没有用。请帮帮我，我真的需要帮助。提前谢谢！

   $("#submitMember").on("click",function(){

    alert("Member submited!");

    //pull the data from the inputs
    var firstName = $("#firstName").val();
    var lastName = $("#memberName").val();
    var email = $("#memberEmail").val();
    var adeziune = $("#adeziune").val();
    var address = $("#memberAddress").val();
    var job = $("#memberJob").val();
    var jobPlace = $("#memberJobPlace").val();
    var memberCNP = $("#memberCNP").val();

    //checking if all the inputs had benn filled
    if(firstName=="" || lastName=="" || email=="" || adeziune=="" || address=="" || job=="" || jobPlace=="" || memberCNP == "") {
