In ff, textcontent is used to implement functions similar to innertext.

Today, I modified a bug. The strange problem is that IE normal FF is not normal. I asked the experts next to me to know that FF uses textcontent to implement functions similar to innertext. The textcontent attribute is different from the innertext attribute in IE. textcontent has a big appetite, and the spaces and line breaks in the middle cannot be ignored. Instead, it can only be replaced with regular expressions.
VaR strmsg = "product [" + goodsname + "] under the experience center [" + shopcentername + "] has less inventory than the actual quantity to be provisioned! "
Alert (strmsg. replace (/(\ n +) | (\ n + $)/g ,""). replace (/(\ r +) | (\ r + $)/g ,""). replace (// \/g ,""));
