您好我正在使用上传文件插件,我需要在上传文件之前验证添加的文件数量......这样的事情
$('#fileupload').bind('fileuploadadd', function (e, data) {
filestoupload++;
var numOfDivs = $('.request').size();
if (numOfDivs < filestoupload) {
upload = false; // Is just an example.
}
});

使用data.files.length
$('#fileupload').bind('fileuploadsubmit', function (e, data) {
var fileCount = data.files.length;
if (fileCount < filestoupload) {
upload = false;
}
});

这对我有用,在你的fileupload定义中添加一个beforesend,然后进行验证
var maxfiles=3;
$('#fileupload').fileupload(({
url: postFileUrl,
submit: function (event, files) {
//check for max files THIS IS WHERE YOU VALIDATE
//console.log(files.originalFiles.length);
var fileCount = files.originalFiles.length;
if (fileCount > maxFiles) {
alert("The max number of files is "+maxFiles);
throw 'This is not an error. This is just to abort javascript';
return false;
}
}
});
到目前为止,抛出是不优雅的,如果你正在实现这个并找到一种方法来避免这种情况请告诉我(现在是必要的,否则它将显示上传的每个文件的错误警报)
