Need to remove everything except alphabetic/letters in javascript?
Here is a simple example of using javascript to replace/remove characters
Step 1: Create a sample string
var a = “This is a test of the JavaScript RegExp objectZ”
Step 2: Use a regular expression to remove characters that don’t match the characters you want
a.replace(/[^a-zA-Z]/g, ”)
“ThisisatestoftheJavaScriptRegExpobjectZ“
