我想为<span>标签显示以下文本。如何转义以下单引号？
$("#spn_err").text($('#txt1').attr('value')+" is not valid");
I want to display the message as 'ZZZ' is not valid. Here $('#txt1').attr('value')is a dynamic value. It may have abc, bcc, ddd, zzz. How can I do this?

Like this:
像这样：
$("#spn_err").text("'" + $('#txt1').val() + "' is not valid");
Inside double quotes, single quotes are normal characters and vice versa. Otherwise you can escape them by prepending a backslash: "\""or '\''.
在双引号内，单引号是普通字符，反之亦然。否则，您可以通过在前面加上反斜杠来转义它们："\""或'\''。
