全部替换<br> javascript中带有空格的标签

Question

Having trouble with very simple thing, How to properly replace all < br> and <br> in the string with the empty space?

This is what I'm trying to use, but I'm receiving the same string.:

var finalStr = replaceAll(replaceAll(scope.ItemsList[i].itemDescr.substring(0, 27), "<", " "), "br>", " ");
function replaceAll(str, find, replace) {
    return str.replace(new RegExp(find, 'g'), replace);
}

You can achieve that using this:

str = str.replace(/<br\s*\/?>/gi,' ');

This will match:

• <br matches the characters <br literally (case insensitive)
• \\s* match any white space character [\\r\\n\\t\\f ]
• Quantifier: * Between zero and unlimited times, as many times as possible, giving back as needed [greedy]
• \\/? matches the character / literally
• Quantifier: ? Between zero and one time, as many times as possible, giving back as needed [greedy]
• > matches the characters > literally
• g modifier: global. All matches (don't return on first match)
• i modifier: insensitive. Case insensitive match (ignores case of [a-zA-Z] )

 let str = "This<br />sentence<br>output<BR/>will<Br/>have<BR>0 br"; str = str.replace(/<br\\s*\\/?>/gi, ' '); console.log(str)
