Javascript JQuery On Select change为变量赋值并重新加载脚本

是否可以将select的选定值分配给脚本变量并重新运行脚本

以下是我当前的代码示例：

<select onchange="reload_script;">
  <option value="123">Select 123</option>
  <option value="456">Select 456</option>
<select>

<div id="123">
    <a href="http://same.com/index.do?n=152991">link title</a>
    <br/><br/>
    <a href="http://some.com/">Link</a>
</div>
<script language="javascript" type="text/javascript">
var code = '123' // <-- THIS VARIABLE WOULD BE THE VALUE OF THE SELECTED DROPDOWN VALUE
</script>

选择123
选择456



var code='123'/如果使用jQuery，则始终可以绑定事件：

否则，在纯JavaScript中，它可能如下所示：

var code = "123";
document.getElementById("mySelect").onchange = function() {
    code = this.value;
    reload_script();
};

如果使用jQuery，则始终可以绑定事件：

否则，在纯JavaScript中，它可能如下所示：

var code = "123";
document.getElementById("mySelect").onchange = function() {
    code = this.value;
    reload_script();
};

试试这个

<select onchange="reload_script();">
  <option value="123">Select 123</option>
  <option value="456">Select 456</option>
<select>

<div id="123">
    <a href="http://same.com/index.do?n=152991">link title</a>
    <br/><br/>
    <a href="http://some.com/">Link</a>
</div>
<script language="javascript" type="text/javascript">
var code = '123' // <-- THIS VARIABLE WOULD BE THE VALUE OF THE SELECTED DROPDOWN VALUE
function script_to_run()
{
//do code here
}

// Call the script one time on page load (only if you need it on page load)
script_to_run();

function reload_script()
{
  script_to_run();//run again
}


</script>
