使用字符串中的\\ n值存储文本区域输入

Question

Hello I am trying to use textarea input.

I am taking the value using $('textarea').val();

When I add multi line input, for example like

    line1
    line2

I want to get the value as line1\\nline2 instead of the default.

Answer 1

Use $("textarea").val().replace(/\\r?\\n/g,"\\\\n")
