getElementById仅为第一个元素返回值

我有一个脚本，在一些生成的元素上根据请求调用，并按id选择指定的元素。我遇到的奇怪问题是，select非常适用于页面上的第一个项目，但对于每个其他项目都返回null。可能是什么原因造成的？

以下是相关的Javascript：

<script type="text/javascript">
function showFrame(content, id, vid, crating)
{
    var container = document.getElementById(vid+'_container');
    $('#'+vid+'_embed').html(content);
    $('#'+vid+'_embed iframe').attr('SCROLLING', 'YES');
    var linkform = document.getElementById(vid + '_linkform');
    linkform.setAttribute('action', '{{ url('/links/reportLink/') }}' + '/' + id);
    $(document).on('submit', '#' + vid+ '_linkform', function() {            
        $.ajax({
            url     : $(this).attr('action'),
            type    : $(this).attr('method'),
            data    : $(this).serialize(),
            beforeSend: function()
            {
                $('#ajax-loading').show();
            },
            success : function( data ) {
                if (data == '{{trans("main.embeds report success")}}')
                {
                    $('#'+vid+'_report-responses').html('<div class="alert alert-success alert-dismissable">{{ trans("main.embeds report success") }}<button type="button" class="close" data-dismiss="alert" aria-hidden="true">&times;</button></div>')
                }
                else
                {
                    console.log(data);
                    $('#'+vid+'_report-responses').html('<div class="alert alert-danger alert-dismissable">' + 'An error occurred while trying to report this link..' + '<button type="button" class="close" data-dismiss="alert" aria-hidden="true">&times;</button></div>')
                }
            },
            error   : function( xhr, err ) {
                alert(err);
            }
        });    
        return false;
    });

    $('#input-'+vid).rateit('value', crating);
    $('#input-'+vid).bind('rated', function(e){
        var ri = $(this);
        var value = ri.rateit('value');
        ri.rateit('readonly', true);
        $.ajax({
            url     : '{{ url('/links/rateLink/') }}',
            type    : 'GET',
            data    : {id: id, value: value},
            beforeSend: function()
            {
                $('#ajax-loading').show();
            },
            success : function( data ) {
                console.log(data);
            },
            error   : function( xhr, err ) {
                alert(err);     
                ri.rateit('readonly', false);
            }
        });
    });

    container.style.display = 'block';
    return false;
}
</script>

1 个答案:

答案 0 :(得分：2)

您的HTML无效（没有结束表单标记）。怀疑是什么时候将HTML粘贴到JSFiddle中并查找任何红色突出显示的元素。

由于ID＆＃39; ed元素为form，因此页面出现问题。

如果你关闭第一个表单元素，第二个表单元素就可以了。
