Processing line breaks in textarea using regular expressions

When the content in textarea is saved to the database, the carriage return linefeed is automatically filtered into spaces, and multiple spaces are converted into one space, that is, \ n and so on are replaced with "" and saved to the database.

Therefore, in order to read the content from the database and write it to HTML in the original format, you must write the content before the text is inserted into the database.

Linefeed into <br/>

 

In this example:

Contentcontentdomaindomaindoc ument. getelementbyid ('content ');

Subscribedomaindomaindoc ument. getelementsbytagname ('form') [0];

Sub. onsubmit = function () {x = content. value;

Content. value = x. Replace (/\ n/g, "<br/>"); y = content. value;

}

Here content is the ID of textarea;
