I have a string, part of which looks like this:
"..devices=233.423.423.553&..."
and I'd like to replace the values of "devices=" with different values like "111.111" so it would appear like:
"..devices=111.111&..."
I think I can do that with some sort of expressions since I need to do that inline.Any trick would be appreciated..
Sure.. Just replace with the string you want to replace with:
var str = '..devices=233.423.423.553&...';
str = str.replace(/devices=[0-9.]+/g, 'devices=111.111');
console.log(str); //..devices=111.111&...
Autopsy:
devices= the literal string devices=[0-9.]+ the digits 0 to 9 or the literal character . matched 1 to infinity times/g means "global". Will replace any occurence rather than just the first one
I'm a relative noob, so forgive me if this is completely inefficient, but how about:
var myStr="..devices=233.423.423.553&..."
var something=myStr.substring((myStr.indexOf("=")+1),(myStr.indexOf("&")));
myStr.replace(something,"111.111.111");
Using regular expressions looks cooler, though.
Just try with:
"..devices=233.423.423.553&...".replace(/(devices)=(?:\d+(\.\d+)*)/, '$1=111.111')
