如何用'\'提取文件名？例如。 C：\testfolder\test.txt [英] How to extract filename with '\'? eg. c:\testfolder\test.txt

问题描述

嗨...


i得到了这个文件名test.txt，其位置为c：\\\ ntostfolder \ test.txt


i可以从上传对象获取完整路径名。但是我想只提取文件名。（test.txt）


i尝试使用split命令，但是当我运行javascript时它会给我错误。

错误：预期的对象。

解决方案

查看此示例代码.....


<输入type = file id = test_file_upload>


现在是js代码..............

document.getElementById（''test_file_upload''）。value。 split（''''）;

//尝试使用像我这样建议的拆分函数....

i hope它会工作。


亲切的问候。

嗨谢谢你的回复...


i已经尝试过使用split命令，当我运行时它给了我错误剧本。似乎与''\\''分裂并不起作用。我试过''\''，" \"，''\\''，" \\"

尝试使用lastIndexOf（）和子串组合。

fileName = filePath.substring（filePath.lastIndexOf（" \\\ \\"））;

hi...

i got this filename test.txt with the location of c:\testfolder\test.txt

i can get the full path name from the upload object. But i want to extract only the filename.(test.txt)

i tried using the split command but it gives me error when i run the javascript.
Error: object expected.

解决方案

<input type = file id = test_file_upload>

document.getElementById(''test_file_upload'').value. split('''');
//try to use the split function like this what i suggested....

Hi thanks for the reply...

i already tried using the split command and it gives me error when i run the script. seems like splitting with ''\'' doesnt work. i tried ''\'', "\", ''\\'', "\\"

try using lastIndexOf(), and substring in combination.
fileName = filePath.substring(filePath.lastIndexOf("\\"));
