Problem working with javascript string containing backslashes

[[email protected]]

I'm trying to write a js function to get the file name from a windows path. The problem I'm having is that js sees a backslash as an escape char and therefore the string variable doesn't have any backslashes in it.

Here is my code.

function GetFileNameOnly() {

var path = {grid.object}._getValue('D','FULLPATH');
//if FULLPATH = 'c:\test\testing.txt' js sees it as 'c:testtesting.txt' and therefore the next bit of code doesn't get the filename because it can't find the last backslash.

var filename = path.substring(path.lastIndexOf("\")+1);

{grid.object}.setValue('D','FILENAME',filename);
}

Have spent hours on google trying to find a solution but no luck. Any help would be much appreciated.

Richard.

Escape your backslashses with another backslash...

if(path == 'c:\\test\\testing.txt'){

Thanks David,

To give more context, the path is being set by the file upload ajs so I don't have control over the path string, hence my challenge.

Then you'd have to add more context because it's unclear what you actually want to do.

Re: Problem working with javascript string containing backslashes

Hi David,

I'm trying to do as mentioned in my original post, the only additional info is that I can't insert double backslashes in the path string as you suggested because I'm not setting the path string myself, the file upload ajs is.

Here is the code from my original post with some additional comments.

function GetFileNameOnly() {

var path = {grid.object}._getValue('D','FULLPATH'); //value in the fullpath field is 'c:\test\testing.txt'

//alert(path); returns c:testtesting.txt because js strips the backslashes. Therefore the next bit of code doesn't find the filename.

var filename = path.substring(path.lastIndexOf("\")+1);

{grid.object}.setValue('D','FILENAME',filename);
}

Richard.

Re: Problem working with javascript string containing backslashes

I'm not seeing that behavior. After I upload the file, my grid detail textbox control is updated with the fully qualified filename by Alpha.

If I then run a Javascript function to get that value, backslashes are included. I get exactly what Alpha sends the textbox control. What shows in your FILENAME field after file upload?

What build/version of Alpha are you using?

Re: Problem working with javascript string containing backslashes

I was a couple of versions behind so I've updated to v12.4.5.4.6 Build 5447.

The value in the grid detail field is being set correctly by the upload ajs and looks like this 'c:\test\testing.txt'

I can assign that value to a variable using var path = {grid.object}._getValue('D','FULLPATH');

alert(path); now returns 'c:\test\testing.txt' which is good.

However I still can't get the filename from the full path using this.

var filename = path.substring(path.lastIndexOf("\")+1); or this var filename = path.substring(path.lastIndexOf("\\")+1); (note the 2 backslashes).

Any ideas on how to get file name only i.e. testing.txt?

Re: Problem working with javascript string containing backslashes

You need to escape the backslash... as in your 2nd example. This works for me.

var filename = path.substring(path.lastIndexOf("\\")+1);
