I have a string "MySites"
. I want to place a space between My
and Sites
.
How can I do this in jQuery or JavaScript?

You can just add a space before every uppercase character and trim off the leading and trailing spaces
s = s.replace(/([A-Z])/g, ' $1').trim()
This will find each occurrence of a lower case character followed by an upper case character, and insert a space between them:
s = s.replace(/([a-z])([A-Z])/g, '$1 $2');
For special cases when 2 consecutive capital letters occur (Eg: ThisIsATest) add additional code below:
s = s.replace(/([A-Z])([A-Z])/g, '$1 $2');
Might I suggest a slight edit to the currently accepted answer:
function insertSpaces(string) {
string = string.replace(/([a-z])([A-Z])/g, '$1 $2');
string = string.replace(/([A-Z])([A-Z][a-z])/g, '$1 $2')
return string;
}
This means that:
ACROText -> ACRO Text
UserNameTest -> User Name Test
Which might be slightly more useful if you are dealing with db column names (And are using acronyms for some things)
This should insert a space between each capital letter that was not preceded by a capital letter.
var myString = "MySites"
var newString = "";
var wasUpper = false;
for (var i = 0; i < myString.length; i++)
{
if (!wasUpper && myString[i] == myString.toUpperCase()[i])
{
newString = newString + " ";
wasUpper = true;
}
else
{
wasUpper = false;
}
newString = newString + myString[i];
}
newString
will have the value you want. Also, if you want to shorten your code using regex, you can use the following code from Javascript camelCase to Regular Form
"thisStringIsGood"
// insert a space before all caps
.replace(/([A-Z])/g, ' $1')
// uppercase the first character
.replace(/^./, function(str){ return str.toUpperCase(); })
regex to find lower case - upper case boundary then insert a space
<div id='x'>ThisIsMySites</div>
$('#x').text( $('#x').text().replace(/([a-z])([A-Z])/g, "$1 $2") );

You can use String#split()
and a look-ahead for the capitalized alphabet ([A-Z]
) and then Array#join()
the array with a space:
let stringCamelCase = "MySites";
let string = stringCamelCase.split(/(?=[A-Z])/).join(" ");
console.log(string)
Or, as a String Object function:
String.prototype.cC2SC = function() {
return this.split(/(?=[A-Z])/).join(" ");
}
console.log("MyCamelCase".cC2SC());
