plupload-中选定的文件数量限制
这是代码的一部分：
inprogress = false;
function getid(id) {
return document.getElementById(id);
}
var uploader = new plupload.Uploader({
runtimes : 'gears,html5,flash,silverlight,browserplus',
browse_button : 'link-browse',
max_file_size : '100mb',
url : 'site/upload/process.php?dir=<?php echo $uplid; ?>',
flash_swf_url : 'site/upload/plupload.flash.swf',
silverlight_xap_url : 'site/upload/plupload.silverlight.xap',
});
uploader.bind('Init', function(up, params) {
//$('filelist').innerHTML = "<div>Current runtime: " + params.runtime + "</div>";
});
uploader.bind('FilesAdded', function(up, files) {
if(uploader.files.length <= 0){
var element = document.getElementById('standby');
element.parentNode.removeChild(element);
}
if(up.files.length > 4 || uploader.files.length > 4)
{
alert('Only 5 files per upload !');
return false;
}
for (var i in files) {
getid('filelist').innerHTML += '<div class="item" id="' + files[i].id + '"><div class="name">' + files[i].name + '</div><div onclick="removeme(\''+files[i].id+'\')" id="remove-'+files[i].id+'" class="remove"></div><div class="size">[ ' + plupload.formatSize(files[i].size) + ' ]</div><div class="percent"></div></div>';
}
});
uploader.bind('UploadFile', function(up, file) {
getid('submit-form').innerHTML += '<input type="hidden" name="file-' + file.id + '" value="' + file.name + '" />';
});
uploader.bind('UploadProgress', function(up, file) {
getid(file.id).getElementsByTagName('div')[3].innerHTML = '<span>' + file.percent + "%</span>";
});
uploader.bind('StateChanged', function(uploader) {
if (uploader.files.length === (uploader.total.uploaded + uploader.total.failed)) {
window.location = "./dl/<?php echo $uplid; ?>"
}
});
getid('link-upload').onclick = function() {
if(uploader.files.length < 1){
alert('Please select files first.');
return false;
}
inprogress = true;
uploader.start();
return false;
};
uploader.init();
function removeme(id){
if(inprogress) return false;
if(uploader.files.length == 1)
getid('filelist').innerHTML += '<div id="standby"></div>';
var element = document.getElementById(id);
element.parentNode.removeChild(element);
var toremove = '';
for(var i in uploader.files){
if(uploader.files[i].id === id){
toremove = i;
}
}
uploader.files.splice(toremove, 1);
}
我可以限制被上传的文件， 如果我有选择的4个文件，我选择5个以上->它会显示错误 但如果我在优先次选择，例如14个文件，它们将显示在“文件列表”来。 如何限制，或者把“返回false”; 感谢您的帮助:)

1. 扩大if(up.files.length > 4 || uploader.files.length > 4)至if(up.files.length > 4 || uploader.files.length > 4 || files.length > 4)。
2. max_file_count：4选项来限制上传文件的数量
3. 在回答罗布W公司的答案，up和uploader是因为它是上传者的实例，因此，冗余，以及它会同时检查(uploader.files.length + files.length) > 4为了检查是否有几个文件，将采取已经“注册”文件到帐户时超过4（例如增加了2个文件，然后3档后）。 所以我会
if(uploader.files.length > 4 || files.length > 4 || (uploader.files.length + files.length) > 4) {
4. - Working for Pupload v2.0
$("#uploader").pluploadQueue({
runtimes: 'html5,html4',
url: 'upload.php',
max_file_size: '2mb',
unique_names: false,
rename: true,
prevent_duplicates: true,
init : {
FilesAdded: function(up, files) {
var max_files = 12;
plupload.each(files, function(file) {
if (up.files.length > max_files) {
alert('You are allowed to add only ' + max_files + ' files.');
up.removeFile(file);
}
});
if (up.files.length >= max_files) {
$('#pickfiles').hide('slow');
}
},
FilesRemoved: function(up, files) {
if (up.files.length < max_files) {
$('#pickfiles').fadeIn('slow');
}
}
},
resize : {width : 700, height : 700, quality : 90},
filters: [
{
title: "Image files",
extensions: "jpg,jpeg,gif,png"
}
]
});
