I have a javascript variable comming from legacy system with backslashes into forward slashes:
'/46\465531_Thumbnail.jpg'
and I am trying to convert into this:
'/46/465531_Thumbnail.jpg'
.
There is no way to fix the problem on the legacy system.
Here is the command I am running on IE8 browser:
javascript:alert("/46\465531_Thumbnail.jpg".replace(/\\/g,"/"));
as response I get:
---------------------------
Message from webpage
---------------------------
/46&5531_Thumbnail.jpg
---------------------------
OK
---------------------------
actually I just want to be translated as '/46/465531_Thumbnail.jpg'
What is wrong?
Summary: The Backslash and Forward SlashThe backslash (\) is mostly used in computing and isn't a punctuation mark. The forward slash (/) can be used in place of “or” in less formal writing. It's also used to write dates, fractions, abbreviations, and URLs.
Press \/ to change every backslash to a forward slash, in the current line. Press \\ to change every forward slash to a backslash, in the current line.
This function will return a new string with the replaced string. A regular expression is used to replace all the forward slashes. As the forward slash (/) is special character in regular expressions, it has to be escaped with a backward slash (\).
You need to double the backslash in your string constant:
alert("/46\\465531_Thumbnail.jpg".replace(/\\/g,"/"));
If your legacy system is actually creating JavaScript string constants on your pages with embedded, un-quoted (that is, not doubled) backslashes like that, then it's broken and you'll have problems. However, if you're getting the strings via some sort of ajax call in XML or JSON or whatever, then your code looks OK.
