移除所有 <br> 从一个字符串

Question

I have a string that i would like to remove all occurrences of <br>

I tried this and it did not work.

    productName = productName.replace("<br>"," ");

However this worked but only for the first <br>

    productName = productName.replace("<br>"," ");

How would I get it to work for all <br> in the string.

Edit: this is the string...

00-6189 Start Mech Switch<br>00-6189 Start Mech Switch<br>00-6189 Start Mech Switch<br>

My apologies for being a little misleading with the <br> as it should have been <br>

Answer 1

Looks like your string is encoded so use

productName = productName.replace(/<br>/g," ");

note the g after the regular expression which means globally, to match all occurrences.

Answer 2

Using regular expression you can use this pattern

/(<|&lt;)br\s*\/*(>|&gt;)/g
productName = productName.replace(/(<|&lt;)br\s*\/*(>|&gt;)/g,' ');

That pattern matches

 <br>, <br />,<br/>,<br     />,<br  >,
 or &lt;br&gt;, &lt;br/&gt;, &lt;br /&gt;

etc...

Answer 3

You could use the g flag in your regular expression. This indicates that the replace will be performed globally on all occurrences and not only on the first one.

productName = productName.replace(/\<br\>/g," ");

Of course you should be aware that this won't replace <br/> nor <br /> but only <br> .

See an example of this working on ideone.

UPDATE:

Now that you've provided an example with your input here's a working regex you might use to replace:

productName = productName.replace(/<br>/g, ' ');

Answer 4

我没有测试过，但你可以试试这样的东西

productName.replace(/\<br\>/g,' ');
