jQuery textarea用纯文本替换回车

Question

I have an input with text that user paste in it. And I have to find all carriage returns chars and replace it with plain text "\\n" . "\\n" should be visible in output textarea. Example

I wrote the code, but output area display my "\\n" as HTML tag and make it carriage returns again. But if I use text func I can't carriage returns chars. Please help.

$("#convert").click( function () {
    var txtValue = $('#input').val();
    $('#output').html(txtValue.replace(/\r?\n/g, "\n"));
});

#input and #output are textfields.

Answer 1

只需转义反斜杠即可：

$('#output').html(txtValue.replace(/\n|\r/g, "\\n"));

Answer 2

you have to use additional slash to put a "\\n" in the string, like this:

$("#convert").click( function () {
    var txtValue = $('#input').val().replace(/\n/g, "\\n");
    $('#output').html(txtValue);
});
