替换textarea换行符以将文本保存到Mysql

Question

I need to replace the newlines in a textarea with the string ", " for storing it in a database. For example, the following string, taken from the textarea:

hi!
line break!

Would be replaced with:

hi!, line break!

Answer 1

Try .value.replace(/ /g, ''). This will replace all occurrences of new line in the text area with empty string.

var textWithoutLineBreak = document.getElementById('txtArea').value.replace(/
/g,'');
console.log(textWithoutLineBreak);

<textarea id="txtArea">hi!
line break!
</textarea>

</div>
