I am trying to see if I can remove some characters from the string that the below script creates:
$(".fileName").text()
The string that is created will be something like:
"bottom.gif (0.43KB)"
I want the string to be: "bottom.gif"
the issue: the image name can be anything. The size of the image will also varry. The only constant that I have to work with are: space after the image name "(" before the file size ")" after the file size
Any help would be great!!!
var text = $(".fileName").text().split(' (')[0];
It splits the text string into an array everywhere this string ' (' occurs:
text[0] = "bottom.gif"
text[1] = "0.43KB)"
and you need only text[0] for use.
note: If the ' (' doesn't exist it will return the whole string:
var text = $(".fileName").text().split('_')[0];
text[0]="bottom.gif (0.43KB)"
text[1] error
so it is safe to use it with [0] and no check if the value is null.
split function splits the string using the argument ' (' as delimiter and it returns an array containing the substrings.. then you want to select the first item of that array since it will be the filename. $(".fileName").text() gets you the text of the HTML element with class="fileName" and then you perform your split on that... this could have been written in several lines but it was written in one line to keep it simple.It's quite simple and will work with any file name:
var text = "bottom.gif (0.43KB)";
text = text.substring(0, text.lastIndexOf('(')-1);
experimentX's solution will fail for some file names. E.g.: "bottom (here is the problem).gif (0.43KB)".
This will do the trick, a little bit of regex
var img_name = "bottom.gif (0.43KB)".split(/[ ]\([0-9a-z\.]{0,}\)/gi)[0]
