我有一个脚本获取用户选择的国家/地区，然后将相应的状态放入状态框中。

这是我的 Javascript 代码：

<script type="text/javascript" src="jquery-1.9.1.min.js">
</script>

<script type="text/javascript">
$(document).ready(function () {
$("#theselect").change(function() {
var option = $(this).val();
        $.get("select.php", {select:option},function(data){
            $("#theresult").html(data).hide().fadeIn(1000);
        });
    });
});
</script>

这是正文中的 HTML 代码：

<select name="theselect" id="theselect">
<option value="">Select</option>
<option value="submit_ind">Submit Individual Need</option>
<option value="submit_org">Submit Organization Need</option>
<option value="missionary">Submit Missionary Need</option>

这是 select.php 脚本，它给出了选择每个选项时要显示的信息：

echo "<script type= 'text/javascript' src = 'http://www.1511project.com/countries.js'></script>
";


***The other options are usually here but due to character restraints I had to delete to rest of it.  So I do have an original If statement and 2 other elseif statement***    

elseif($_GET['select'] == 'missionary') {

echo "<script>print_country('country');</script>";

?>
<script>

function limitText(limitField, limitCount, limitNum) {
    if (limitField.value.length > limitNum) {
        limitField.value = limitField.value.substring(0, limitNum);
    } else {
        limitCount.value = limitNum - limitField.value.length;
    }
}

function validateForm()
{
var x=document.forms["myForm"]["firstname"].value;
if (x==null || x=="")
  {
  alert("First name must be filled out");
  return false;
  }

var r=document.forms["myForm"]["titleofneed"].value;
if (r==null || r=="")
  {
  alert("Title of need must be filled out");
  return false;
  }

var s=document.forms["myForm"]["country"].value;
if (s==null || s=="")
  {
  alert("Country must be filled out");
  return false;
  }


var u=document.forms["myForm"]["phone"].value;

var b=document.forms["myForm"]["email"].value;
if ((b==null || b=="") && (u==null || u==""))
  {
  alert("Email or Phone must be provided for contact information.");
  return false;
  }

var c=document.forms["myForm"]["city"].value;
if (c==null || c=="")
  {
  alert("City must be filled out");
  return false;
  }

var d=document.forms["myForm"]["state"].value;
if (d==null || d=="")
  {
  alert("State must be filled out");
  return false;
  }

var h=document.forms["myForm"]["recurring"].value;
if (h==null || h=="")
  {
  alert("Recurring need must be filled out");
  return false;
  }

var j=document.forms["myForm"]["typeofneed"].value;
if (j==null || j=="")
  {
  alert("Type of need must be filled out");
  return false;
  }

}

我遇到的问题是，当人们第一次选择“传教士”选项时，它不会显示传教士表格。但是，如果我先选择另一种形式，然后选择传教士选项，它将显示并正常工作。或者，如果我先选择另一种形式，那么传教士的选择就会起作用。但是如果我先选择“传教士”就不行了。

我已经在“传教士”形式的这段代码中找到了问题的根源：

<script>print_country('country');</script>

如果该代码在表单中的任何位置，则表单不会第一次弹出。

任何人都可以帮忙吗？

countries.js当您返回非“传教士”案件时，您似乎只将图书馆包含在您的页面上。确保你在你里面包含那个文件elseif：

elseif($_GET['select'] == 'missionary') {

    echo "<script type= 'text/javascript' src = 'http://www.1511project.com/countries.js'></script>";
    echo "<script>print_country('country');</script>";

}

编辑：为什么你甚至在你的 AJAX 返回中包含那个 js 文件，而不是总是在你的父页面中。这样它就可以在需要时随时使用。它不会在原始页面加载上提供太多开销，但作为 AJAX 返回的一部分会导致问题。
