How do I replace all line breaks in a string with <br /> tags?
How can I read the line break from a value with Javascript and replace all the line breaks with br tags?
Example:
A variable passed from PHP as below:
"This is man.
Man like dog.
Man like to drink.
Man is the king."
I would like my result to look something like this after the Javascript converts it:
"This is man<br /><br />Man like dog.<br />Man like to drink.<br /><br />Man is the king."
这将把所有返回转换为html。
str = str.replace(/(?:rn|r|n)/g, '<br>');
If your concern is just displaying linebreaks, you could do this with CSS.
HTML
<div class="white-space-pre">Some test
with linebreaks</div>
CSS
.white-space-pre {
white-space: pre-wrap;
}
jsfiddle https://jsfiddle.net/yk1angkz/125/
Note : Pay attention to code formatting and indenting, since white-space: pre-wrap will display all whitespaces (except for the last newline after the text, see fiddle).
没有正则表达式：
str = str.split("n").join("<br />");
