I have an string as:
0123456789,, 0987654213 ,, 0987334213,, ......
How can I convert this into
0123456789, 0987654213, 0987334213, ......
ie I want to remove the second comma
You can do it very simply, like this using regex.
var str = "0123456789,,0987654213,,0987334213,,,,,9874578";
str=str.replace(/,*,/g,',');
console.log(str)
var str = "0123456789,, 0987654213 ,, 0987334213,, ......"
console.log(str.replace(/\,+/g,","));
You can use replace() method with regular expression with g flag to replace all instances ',,' with ',':
str.replace(/,,/g, ",");
Here's a simple example
var str = '0123456789,, 0987654213 ,, 0987334213'; str = str.replace(/,,/g, ","); console.log(str);
这将用单个逗号替换所有出现的连续逗号:
str.replace(/,+/g, ',');
var str = "0123456789,, 0987654213 ,, 0987334213,," str = str.split(",,").join(",") console.log(str);
There is a replace method for String. You can replace ',,' with a ','.
An example:
var str = "0123456789,, 0987654213,, 0987334213,";
var newStr = str.replace(/,,/g,','));
The output:
0123456789, 0987654213, 0987334213,
