为什么javascript替换方法（没有正则表达式）在angularjs表达式中不起作用以删除？

Question

The SO link Javascript Regular expression to remove unwanted <br>, &nbsp; sp tells us to remove an expression using regex.But i want to remove &nb sp; without using regex.Angular expression:

{{notification.noti_val)}};Did:{{notification.noti_val.replace(/\&nb sp;/g, ' ')}}

.But doesnt delete the &nb sp;

Note:did a space between nb and sp cause SO was parsing it as whitespace so was showing it as whitespace

Answer 1

Use \\s* instead of a literal space character. \\s should match any kind of whitespace character. Adding * next to \\s should match any kind of space zero or more times.

noti_val.replace(/\&nb\s*sp;/g, ' ')

Note that this would replace   with a space character. If you want to remove then replace it with empty string.

noti_val.replace(/\&nb\s*sp;/g, '')
