自动单击jquery/js中的超链接

Question

我有一个链接，我需要使用jquery或js自动点击它。

如果我点击链接，文件将被删除，但我需要在上传所有文件后自动删除。

实际上，我正在使用plupload，它可以像$('#uploader').plupload('clearQueue');一样删除jquery UI的所有文件，但这不起作用！

这是我的链接

<a id="deleteallfiles" href="#">[Remove all files]</a>

这是我的脚本：

 <script type="text/javascript">
    // Convert divs to queue widgets when the DOM is ready
    $(function () {
        $("#uploader").plupload({
            // General settings
            runtimes: 'gears,flash,silverlight,browserplus,html5',
            url: 'Final.aspx',
            max_file_size: '10mb',
            max_file_count: 25,
            chunk_size: '1mb',
            unique_names: true,

            // Resize images on clientside if we can
            //                    resize: { width: 320, height: 240, quality: 90 },

            // Specify what files to browse for
            filters: [
        { title: "Image files", extensions: "jpg,gif,png" },
        { title: "Zip files", extensions: "zip" }
    ],

            // Flash settings
            flash_swf_url: 'js/plupload.flash.swf',

            // Silverlight settings
            silverlight_xap_url: 'js/plupload.silverlight.xap'
        });


        // Client side form validation
        $('form').submit(function (e) {
            var uploader = $('#uploader').plupload('getUploader');

            // Files in queue upload them first
            if (uploader.files.length > 0) {
                // When all files are uploaded submit form
                uploader.bind('StateChanged', function () {
                    if (uploader.files.length === (uploader.total.uploaded + uploader.total.failed)) {
                        $('form')[0].submit();
                    }
                });

                uploader.start();
            }
            else
                alert('You must at least upload one file.');

            return false;
        });
        var uploader = $('#uploader').plupload('getUploader');
        uploader.bind('FileUploaded', function (up, file, res) {
            $('#showfilelist').append("<div id=" + file.id + " class='thumb'><a href='uploads/" + document.getElementById("currentDirectory").value + "/" + file.name + "' target='_blank' rel='gallery'><img src='uploads/" + document.getElementById("currentDirectory").value + "/" + file.name + "' width='50' height='50'/></a></div>");

          });

        //            $('#uploader').plupload('clearQueue');

        $('#deleteallfiles').click(function (e) {
            $.each(uploader.files, function (i, file) {
                uploader.splice(file);
            });
        });

      });

</script>

Answer 1

只需使用单击功能即可。即

$('#someElement').click();

Answer 2

$('#someElement').trigger('click');

Answer 3

Do可以只做：

$("a").click();

我认为这可能是触发点击事件的最简单的方式。

从jquery documentation

这只是对以下内容的简写：

.trigger('click')
