i need help in this:i want to remove from a string a specific value. for example i have this code:
document.getElementById("sub_subject_temp"+id1).value = old_sub_subject_string.replace(/theVal/,"");
if my string is:
6-7,6-3,6-1,
and i want to remove:
6-3,
it would look like this: 6-7,6-1, i have tryed the
str.replace(/val/, "");
but it return 6, any idea to do this thing?
"6-7,6-3,6-1".replace(/6-3,/, '');
//"6-7,6-1"
How about replacing the string you want to remove, not "val"? Try
str.replace(/6-3,/, "");
If you mean you use a variable val whose value is like 6-3;, you need to use new RegExp() to construct the regex.
var str = '6-7,6-3,6-1,';
var val = '6-3,';
str = str.replace(new RegExp(val), '');
There is a way to do this without .replace. Although it is more complex, it works.
var rstring = "6-7,6-3,6-1";
var nstring = rstring.split("6-3,");
var finishedstr = nstring[0] + nstring[1];
So, in the above code the original string is split into two while removing "6-3," from the string. The two new sub-strings are recombined without the "6-3,", allowing a finished string of "6-7,6-1", or in this case, the variable finishedstr.
