HTML/JavaScript的/ PHP国家和国家名单

Question

我有一个是得到全国用户选择，然后脚本会将对应状态的状态框。

这里是头我的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> 

这里是人体的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> 

这里是给是什么样的信息select.php脚本当每个选项被选中时显示：

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; 
    }

    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，当人们选择SE中的“传教士”选项的第一次，也不会显示宣教形式。但是，如果我选择另一种形式，第一，然后选择传教士选项，它会显示和做工精细。或者如果我先选择另一种形式，那么它的传教选择将起作用。但如果我首先选择“传教士”，这是行不通的。

我在“传教”的形式问题的根源找到了这一段代码：

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

如果代码是在任何地方的形式，形式不会拉起第一次。

任何人都可以帮忙吗？

Answer 1

你似乎只包括countries.js库到你的页面，当你返回非“传教士”的情况。确保你包括你内心elseif该文件：

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：为什么你甚至包含js文件在你的AJAX回报，没有它总是你父页面。这样就可以随时使用了。它不提供原始页面加载开销很大，但它造成的问题作为一个AJAX回报的一部分。
