HTML：

<select id="select">
    <option selected>Default</option>
    <option value="refresh">Refresh</option>
</select>

JavaScript：

function onchange(e) {
    if (e.currentTarget.value === 'refresh') {
        window.location.reload();
    }
}

document.getElementById('select').addEventListener('change', onchange);

演示：http: //jsfiddle.net/w425208t/

使用window.location.href = yourUrl;它将“重定向”您到带有 url 的页面yourUrl

您可以使用以下任何一种：

window.location.reload(false); 
// If we needed to pull the document from
//  the web-server again (such as where the document contents
//  change dynamically) we would pass the argument as 'true'.
//i.e. 'true' will force the page to reload from the server. 'false' will reload from cache, if available.

or 

location.reload(); 

or 

window.location.replace(window.location.pathname);
