      public @ResponseBody List<Environments> getEnvironmentNames(@RequestParam String selectedaname ) throws SQLException {
        List<org.mvc.domain.Environments> environmentnamesList = loginDelegate.getEnvironments(selectedcustomername);

    if (section==1)
        return headerHeight1;
    if (section==2)
        return headerHeight2;
    if (section==3)
        return headerHeight3;
    if (section==4)

    else if (currentSectionIndex==6)
        headerHeight5= updatedValue;

您需要在两者之间留一个空格：

$('#adropdownDetails :selected').text()

$('#adropdownDetails:selected').text()这可能不是您要寻找的价值。这是whitespace或新行字符。你可以查看下面的代码：

＆＃13;

var selval = $('select:selected').text();
$('pre').html('<p>'+selval+'</p>');

＆＃13;

p{border:solid 1px grey; padding:2px;}

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select><option>select...</option></select>
<pre></pre>

＆＃13;
