替换所有< br>标记与javascript中的空格 [英] Replace all <br> tag with space in javascript

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);
}

推荐答案

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]
  
  
  • <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]
    
    
    • 量词：？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)
