如何使用JavaScript从字符串中删除特殊字符

Question

当＃出现在字符串中时，我想使用JavaScript在新行中拆分它。

请帮我。

输入样例：

This application helps the user to instantiate #Removed#Basic#afdaf#Clip#Python#matching of many parts#

预期产量：

This helps the user to instantiate 
Removed
Basic
afdaf
Clip
Python
matching of many parts

Answer 1

您可以简单地replace '#' replace为'\\n'

 var mainVar = 'This application helps the user to instantiate#Removed#Basic#afdaf#Clip#Python#matching'; console.log(mainVar.replace(/[^\\w\\s]/gi, '\\n')); 

Answer 2

将字符串转换为数组，然后遍历数组，并逐个打印值。

 var str = "helps the user to instantiate #Removed#Basic#afdaf#Clip#Python#matching of many parts#"; str.split("#").forEach(function(entry) { console.log(entry); }); 

Answer 3

您可以尝试以下方法：

您应该使用带有单个正则表达式的字符串替换功能。 假设有特殊字符

 var str = "This application helps the user to instantiate #Removed#Basic#afdaf#Clip#Python#matching of many parts#"; console.log(str.replace(/[^a-zA-Z ]/g, "\\n")); 

Answer 4

以下解决方案将基于＃拆分并将其存储在数组中。 此解决方案可用于拆分字符串。

var sentence = '#Removed#Basic#afdaf#Clip#Python#matching of many parts#'

var newSentence = [];
for(var char of sentence.split("#")){
    console.log(char); // This will print each string on a new line
    newSentence.push(char);
}
console.log(newSentence.join(" "));
