我想要做的是使用 html 下拉菜单隐藏或显示我的 HTML 中的 div。首先完全在 javascript 中执行此操作但有问题。

基本上，用户会在 ddl 中选择一个部门，比如“pub-chains”，与该部门关联的 pub div 将显示在页面上，而其他 div 则隐藏在视图之外，任何有这样做经验的人吗？

HTML

<html>
  <head>Select a Business Sector:</head>
  <form>
                <p>
                <select id="dropdown" name="dropdown">
                    <option value="Pub-Chains" selected="selected"> Pub Chains </option>
                    <option value="Councils">Councils </option>
                    <option value="Property">Property </option>
                    <option value="Various">Various </option>
                    <option value="Universitys">Universitys </option>
                </select>
                </p>
            </form>
  <body>

干得好。使用 jQuery：

var select = $( '#dropdown' );

function showTab( name ) {
  name = '#' + name;
  $( 'div' ).not( name ).hide();
  $( name ).show();
}

select.change( function() {
  showTab( $( this ).val() );   
});

showTab( select.val() );

我将使用本机 Javascript 试一试：

编辑：特别感谢 Khez 建议使用三元运算符。

document.getElementById('dropdown').onchange = function(e) 
{

    var selectedValue = document.getElementById('dropdown').value,
        options = document.getElementById('dropdown').options,
        iter;

    for (iter = options.length - 1; iter >= 0; iter -= 1)
    {
        document.getElementById(options[iter].value).style.display =  
            (options[iter].value === selectedValue ? 'block' : 'none');
    }
}
