我正在尝试设置一个注册页面，这也是散列和散列数据的哈希值，但是服务器上没有任何处理，并且我没有得到控制台错误，有人能告诉我哪里出错吗？

这可能会对您有所帮助：
从表单中删除您的操作标记，因为它将数据提交到index.html是错误的。
将您的.click()更改为：
$("#register").click(function(e){
e.preventDefault();
firstName=$("#firstName").val();
lastName=$("#lastName").val();
userName=$("#userName").val();
reuserName=$("#reuserName").val();
emailAddress=$("#emailAddress").val();
reemailAddress=$("#reemailAddress").val();
pass=$("#password").val();
rePassword=$("#rePassword").val();
$.ajax({
type: "POST",
url: "create.php",
data:
"firstName="+firstName+
"&lastName="+lastName+
"&userName="+userName+
"&reuserName="+reuserName+
"&emailAddress="+emailAddress+
"&reemailAddress="+reemailAddress+
"&password="+pass+
"&rePassword="+rePassword,
success: function(html){
if(html=='true') {
console.log("Submitted!");
}
else if(html=='false'){
console.log("Error!");
}
else{
console.log("Error!"+html);
}
},
beforeSend:function()
{
},
error: function(e)
{
console.log("Error!");
console.log(e);
}
});
return true;
});
我刚刚添加e.preventDefault()，因为您的按钮类型为"submit"，因此它会提交表单。在ajax调用中，您无需重新加载或重定向到任何页面以保存数据或发送数据。 ajax为你做到了。
这应该保存您已经制作create.php的数据。
如果您还可以在表单中添加
onsubmit="return false"属性 e.preventDefault（）不是你的选择。或者更改按钮类型submit到button，这不会提交您的表单。
PS：如果对您来说听起来不错，请尝试序列化表单，以便您可以自己节省准备数据的混乱。如果你想要，试试这个：
url : "page_url.php",
data : $('#your_form_id').serialize(),
这对你有用，你可以摆脱那些代码行.val()。
干杯!!
