Like the title says, i would like to remove an underscore within a String with a regex. This is what i have:
function palindrome(str) {
str = str.toLowerCase().replace(/[^a-zA-Z]/g, '',/\s/g, '',/[0-9]/g,'');
if (str.split("").reverse().join("") !== str) {
return false;
}
else {
return true;
}
}
palindrome("eye");
445
To replace the underscores with spaces in a string, call the replaceAll() method, passing it an underscore and space as parameters, e.g. str. replaceAll('_', ' ') . The replaceAll method will return a new string where each underscores is replaced by a space.
Use the String. replace() method to remove all hyphens from a string, e.g. const hyphensRemoved = str. replace(/-/g, ''); . The replace() method will remove all hyphens from the string by replacing them with empty strings.
You can use the string lstrip() function to remove leading underscores from a string in Python. The lstrip() function is used to remove characters from the start of the string and by default removes leading whitespace characters.
Use .replace(/_/g, "") to remove all underscores or use .replace(/_/g, " ") to replace them with a space.
Here is an example to remove them:
var str = "Yeah_so_many_underscores here";
var newStr = str.replace(/_/g, "");
alert(newStr);You can use .replace to achieve this. Use the following code. It will replace all _ with the second parameter. In our case we don't need a second parameter so all _ will be removed.
<script>
var str = "some_sample_text_here.";
var newStr = str.replace(/_/g , "");
alert ('Text without underscores : ' + newStr);
</script>
