通过javascript对象访问数据并将其打印在html页面上

Question

I have a object in which each key has a string corresponds to it for ex { 0 :'hello\\nworld', 1:'\\njavascript\\nis\\nawesome' } now I want to print this in html page and for each \\n there should be a break line for example -

hello(new line)
world(new line)
javascript(new line)
is(new line)
awesome(new line)

as a new programmer I don't know hoe to do it any help would be appreciated

Answer 1

You can use String.prototype.replace() . and regular expression.By using g flag in regex you can replace all the \\n with <br> .

 let obj = { 0 :'hello\\nworld', 1:'\\njavascript\\nis\\nawesome' } for(let key in obj){ let reg = new RegExp('\\n',"g"); document.body.innerHTML += obj[key].replace(/\\n/g,'<br>'); } 

Answer 2

将\\n替换为<br/>并将其全部放置在任何可见的html标记中，它将显示您的文本，并在遇到<br/>时返回到行。
