替换所有< br>标记与javascript中的空格
问题描述：
麻烦很简单，
如何正确替换所有<带有空格的字符串中的br> 和< br> ？
这是我正在尝试使用的，但我收到相同的字符串。：
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);
}
答
你可以用这个实现：
str = str.replace(/<br\s*\/?>/gi,' ');
这将匹配：
-
< br匹配字符< br字面意思（不区分大小写） -
\ * *匹配任何空格字符[\\\\\\\\\\ code>- 量词：
*在零和无限次之间，尽可能多次，根据需要回馈[贪心]
-
<brmatches the characters<brliterally (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]

？在零到一次之间，尽可能多次，根据需要回馈[贪心]
- Quantifier:
?Between zero and one time, as many times as possible, giving back as needed [greedy]
var str = "This<br />phrase<br>output<BR/>will<Br/>have<BR>0 br"; str = str.replace(/<br\s*\/?>/gi, ' '); console.log(str) - Quantifier:
