I have a string that i would like to remove all occurrences of <br>
我有一个字符串，我想删除所有出现的 <br>
I tried this and it did not work.
我试过这个，但没有用。
productName = productName.replace("<br>"," ");
However this worked but only for the first <br>
然而，这有效但仅适用于第一个 <br>
productName = productName.replace("<br>"," ");
How would I get it to work for all <br>in the string.
我将如何让它对<br>字符串中的所有人都起作用。
Edit: this is the string...

Looks like your string is encoded so use
看起来您的字符串已编码，因此请使用
productName = productName.replace(/<br>/g," ");
note the gafter the regular expression which means globally, to match all occurrences.
注意g正则表达式后面的意思是全局匹配所有出现的。
回答by DavideDM
Using regular expression you can use this pattern
使用正则表达式，您可以使用此模式
/(<|<)br\s*\/*(>|>)/g
productName = productName.replace(/(<|<)br\s*\/*(>|>)/g,' ');
That pattern matches
该模式匹配
<br>, <br />,<br/>,<br />,<br >,
or <br>, <br/>, <br />
etc...
等等...

You could use the gflag in your regular expression. This indicates that the replace will be performed globally on all occurrences and not only on the first one.
您可以g在正则表达式中使用该标志。这表明替换将在所有事件上全局执行，而不仅仅是在第一个。
productName = productName.replace(/\<br\>/g," ");
Of course you should be aware that this won't replace <br/>nor <br />but only <br>.
当然，您应该知道这不会取代<br/>也不会<br />仅取代<br>.
See an exampleof this working on ideone.
看到一个例子这个工作对ideone的。
UPDATE:
更新：
Now that you've provided an example with your input here's a working regex you might use to replace:
既然您已经提供了输入示例，这里是您可以用来替换的有效正则表达式：
productName = productName.replace(/<br>/g, ' ');

I've not tested it but you could try something like this
我没有测试过，但你可以试试这样的
productName.replace(/\<br\>/g,' ');
