[英]Javascript new line built string?
I'm building a string in JavaScript FE like you can see below, my attempt is to print some data in different rows.我正在 JavaScript FE 中构建一个字符串,如下所示,我的尝试是在不同的行中打印一些数据。 In my JavaScript I build the string the use
getElement()
and textContent
to attach the string at the paragraph.在我的 JavaScript 中,我使用
getElement()
和textContent
构建字符串以在段落中附加字符串。
I've tried <br>
<br/>
\n
<\r
, all with no results.我试过
<br>
<br/>
\n
<\r
,都没有结果。
var str;
str+="text" + data[0];
str+= //Here need new line
str+="text" + data[1];
var p=document.getElementById("paragraph");
p.textContent = str;
A couple options you have are:您有几个选择:
<br/>
in the string and set the p.innerHTML = str
instead of setting textContent<br/>
并设置p.innerHTML = str
而不是设置 textContent let myEl = document.getElementById('myelement'); let data = 'test 1'; data += '<br/>'; data += 'test 2'; myEl.innerHTML = data;
<div id="myelement"></div>
OR或者
\n
character in the string and then use a white-space: pre
in the CSS of your element\n
字符,然后在元素的 CSS 中使用white-space: pre
let myEl = document.getElementById('myelement'); let data = 'test 1'; data += '\n'; data += 'test 2'; myEl.textContent = data;
#myelement { white-space: pre; }
<div id="myelement"></div>
It might be easier to use a template string , and then use innerText
rather than textContent
as they are different .使用模板字符串可能更容易,然后使用
innerText
而不是textContent
,因为它们是不同的。
const arr = ['Bob', 'Jane']; const str = ` text: ${arr[0]} text: ${arr[1]} `; document.body.innerText = str;
If you need a string that can be displayed/downloaded as a file and displayed in html at the same time, i would use \n
and innerText
:如果您需要一个可以作为文件显示/下载并同时显示在 html 中的字符串,我会使用
\n
和innerText
:
var str;
str+="text" + data[0];
str+= '\n';
str+="text" + data[1];
var p=document.getElementById("paragraph");
p.innerText = str;
the \n
will be replaced by <br/>
automatically when using innerText, and you wont need to style it with whitespace
, and you could use the resulting string, to perhaps start a file download在使用 innerText 时,
\n
将被自动替换为<br/>
,您不需要使用whitespace
来设置它的样式,并且您可以使用生成的字符串,也许可以开始文件下载
