我正在使用jqueryfiletree plugin,它似乎已经建立并相当顺利,但我有一些问题:
尽管选项设置如下:
$(function() {
$("#sourceFileTree").fileTree({
onlyFolders: true,
root: "C%3a%5cProjects%5cBMW%5cCode%5cFileTransfers.Web",
script: "/FileTree/Tree",
multiFolder: false,
multiSelect: false,
preventLinkAction: true
});
});
onlyFolders
似乎被忽略了,任何打开的文件夹也会显示它包含的文件。multiSelect: false
同样如此。虽然我可以一次只“选择”(以粗体突出显示)一个文件,但我仍然可以根据需要检查多个文件夹和文件复选框。multiFolder: false
似乎有记录,但我不知道是否因为这是默认行为。如果我想配置此小部件以允许用户只选择一个文件夹,我做错了什么?
答案 0 :(得分:4)
连接器(是的,你的是自定义的)是对结果执行过滤的原因。如果您不是在寻找/使用jQuery插件中传递的参数,那么结果将不是您所期望的。从上面发布的链接(https://github.com/jqueryfiletree/jqueryfiletree/blob/master/dist/connectors/Asp.Net-MVC/FileTreeController.cs)和似乎使用适用选项(https://github.com/jqueryfiletree/jqueryfiletree/blob/master/dist/connectors/jqueryFileTree.php)的PHP版本中,我们可以稍微更新一下以返回更好的结果集。
注意 - 我们无法深入了解您的文件,因此这是一个使用一些样板代码的非常新手的例子。另外,我知道你的答案是关于.NET核心的,但即使4.6和Core之间的语法不完全相同,逻辑应该仍然适用
[HttpPost]
//notice the added additional params to the expected request variables
//these appear to match the names of the jQuery options
public virtual ActionResult GetFiles(string dir, bool multiSelect,
bool onlyFolders, bool onlyFiles)
{
const string baseDir = @"/App_Data/userfiles/";
dir = Server.UrlDecode(dir);
string realDir = Server.MapPath(baseDir + dir);
//validate to not go above basedir
if (! realDir.StartsWith(Server.MapPath(baseDir)))
{
realDir = Server.MapPath(baseDir);
dir = "/";
}
List<FileTreeViewModel> files = new List<FileTreeViewModel>();
DirectoryInfo di = new DirectoryInfo(realDir);
foreach (DirectoryInfo dc in di.GetDirectories())
{
files.Add(new FileTreeViewModel() { Name = dc.Name, Path = String.Format("{0}{1}\\", dir, dc.Name), IsDirectory = true });
}
foreach (FileInfo fi in di.GetFiles())
{
files.Add(new FileTreeViewModel() { Name = fi.Name, Ext = fi.Extension.Substring(1).ToLower(), Path = dir+fi.Name, IsDirectory = false });
}
//lets filter some results using the properties of
//the `FileTreeViewModel()` class
//I have no idea how you are wanting to use multiSelect, so
//it has been left out of this example.
if(onlyFolders){
files = files.Where(x=>x.IsDirectory).ToList();
}
if(onlyFiles){
files = files.Where(x=>!x.IsDirectory).ToList();
}
return PartialView(files);
}
