如何替换`和 <br> `

Question

how to replace multiple occurrences of &nbsp; and <br> &nbsp; and <br> at start of the string with javascript regex?

Answer 1

myString = myString.replace(/^(&nbsp;|<br>)+/, '');

... where / ... / denotes a regular expression, ^ denotes start of string, ($nbsp;|<br>) denotes "   or <br> ", and + denotes "one or more occurrence of the previous expression". And then simply replace that full match with an empty string.

Answer 2
