删除每个换行符后的字符串

Question

嗨，我是javascript的新手，我有一些文字，包含多行。我想删除字符串'（''在每行中断后，然后用逗号替换所有换行符。这是我到目前为止

var text = "black gloves (?) 36622\nred eyes (?) 587624\nsolo (?) 1975043\nshort hair (?) 1628547"

var draft = text.replace(/(\r\n|\n|\r)/gm,",");
var final = draft.split('(')[0];
alert(final);

我似乎无法得到我的代码给我这个结果：

black gloves,red eyes,solo,short hair

但它只是给了black gloves

Answer 1

尝试这个：

 var text = "black gloves (?) 36622\\nred eyes (?) 587624\\nsolo (?) 1975043\\nshort hair (?) 1628547" var draft = text.replace(/(\\r\\n|\\n|\\r)/gm," "); var draft = draft.replace(/(\\d)+/gm,","); var draft = draft.replace(/\\(\\?\\)/gm,""); alert(draft); 

要么

 var text = "black gloves (?) 36622\\nred eyes (?) 587624\\nsolo (?) 1975043\\nshort hair (?) 1628547" var draft = text.replace(/\\(\\?\\)[ \\d\\r\\n]+/gm,","); alert(draft); 

Answer 2

您必须知道String.prototype.split（）返回一个array ，在这种情况下，它不必使用它。

您只需要使用String.prototype.replace（）方法来实现您想要的，如下所示：

 var text = "black gloves (?) 36622\\nred eyes (?) 587624\\nsolo (?) 1975043\\nshort hair (?) 1628547"; var draft = text.replace(/(\\r\\n|\\n|\\r)/gm, ",").replace(/[^a-zA-Z,]/g, " ").replace(/\\s+,/g, ",").trim(); console.log(draft); 

Answer 3

在这里它https://jsfiddle.net/loginshivam/724phqag/

var text = "black gloves (?) 36622\nred eyes (?) 587624\nsolo (?) 1975043\nshort hair (?) 1628547"

var array = text.split("\n");
var val;
for(in=0;in<array.length;in++){
    val=array[in];
    if(in == 0)
       text = val.substring(0, val.indexOf("(")) ;
    else
    text = text  + ","+ val.substring(0, val.indexOf("("));
}

Answer 4

没有正则表达式：

 var text = "black gloves (?) 36622\\nred eyes (?) 587624\\nsolo (?) 1975043\\nshort hair (?) 1628547" var textToArray = text.split('\\n'); for(var i = 0; i<textToArray.length; i++) { var index = textToArray[i].indexOf('(') - 1; textToArray[i] = textToArray[i].slice(0,index); } var finalString = textToArray.join(', '); alert(finalString); 

Answer 5

text.replace(/ \(.\) \d+/g, '').replace(/\r?\n/g, ',')

就像第二行替换一样简单。

 var text = "black gloves (?) 36622\\nred eyes (?) 587624\\nsolo (?) 1975043\\nshort hair (?) 1628547"; var final = text.replace(/ \\(.\\) \\d+/g, '').replace(/\\r?\\n/g, ','); alert(final); 

Answer 6

备用正则表达式解决方案（ https://regex101.com/非常有用）。 它有点脆，因为它假定每一行都经过适当格式化并包含模式。

 var text = "black gloves (?) 36622\\nred eyes (?) 587624\\nsolo (?) 1975043\\nshort hair (?) 1628547" console.log(text.replace(/ \\(\\?\\) .*(\\n|$)/g, ",").slice(0,-1));
