Whatever string is given I have to see if there is exactly one space after and before =, If it is more than one space in either side I have to reduce that to one and if there is none, I have to insert one.
How should I do that ? String can contain anything.
Thanks
You can do this:
str = str.replace(/ *= */g, " = ");
This will replace all = characters regardless of how many spaces it is surrounded by. The * quantifier will match as most spaces as possible while allowing even no spaces at all.
Try this:
var out = in.replace(/ *= */g, " = ");
Basically just replace zero or more instances of a space with a space and you get both desired results. If zero, then you get one. If more than one, you get one.
Make the following replacement:
s = s.replace(/ *= */g, ' = ')
myString.replace(/\s*=\s*/g, " = ")
will do the same as other given answers, but allow any type of space characters to be replaced (spaces, tabs, etc.).
/\s*=\s*/gmin case you want all whitespace characters to be converted to single space characters in your expression
