提问by shaz
I have written the following code. But it is removing only not <br>
我已经编写了以下代码。但它只是删除 不<br>
var docDesc = docDescription.replace(/( )*/g,"");
var docDesc1 = docDescription.replace(/(<br>)*/g,"");

You can achieve removing <br>with CSS alone:
您可以<br>单独使用 CSS实现删除：
#some_element br {
display: none;
}
If that doesn't fit your needs, and you want to really delete each <br>, it depends, if docDescriptionis really a string (then one of the above solutions should work, notably Matt Blaine's) or a DOM node. In the latter case, you have to loop through the br elements:
如果这不符合您的需求，并且您想真正删除 each <br>，这取决于它是否docDescription真的是一个字符串（那么上述解决方案之一应该可以工作，特别是 Matt Blaine 的）或 DOM 节点。在后一种情况下，您必须遍历 br 元素：
//jquery method:
$('br').remove();
// plain JS:
var brs = common_parent_element.getElementsByTagName('br');
while (brs.length) {
brs[0].parentNode.removeChild(brs[0]);
}
Edit:Why Matt Baline's suggestion? Because he also handles the case, where the <br>appears in an XHTML context with closing slash. However, more complete would be this:
编辑：为什么是马特巴林的建议？因为他也处理这种情况，即<br>出现在 XHTML 上下文中并带有斜杠。但是，更完整的是：
/<br[^>]*>/

Try:
尝试：
var docDesc = docDescription.replace(/[&]nbsp[;]/gi," "); // removes all occurrences of
docDesc = docDesc.replace(/[<]br[^>]*[>]/gi,""); // removes all <br>

Try "\n"...see if it works.
尝试“\n”...看看它是否有效。

What about:
关于什么：
var docDesc1 = docDescription.replace(/(<br ?\/?>)*/g,"");
回答by Darin Dimitrov
This will depend on the input text but I've just checked that this works:
这将取决于输入文本，但我刚刚检查过它是否有效：
var result = 'foo <br> bar'.replace(/(<br>)*/g, '');
alert(result);

Try this
尝试这个
var text = docDescription.replace(/(?: |<br>)/g,'');

You can do it like this:
你可以这样做：
var cell = document.getElementsByTagName('br');
var length = cell.length;
for(var i = 0; i < length; i++) {
cell[0].parentNode.removeChild(cell[0]);
}
It works like a charm. No need for jQuery.
它就像一个魅力。不需要 jQuery。
