Html ("get mailbox registration code"); $("# code_send_btn") .removeAttr ("disabled", "disabled") ClearInterval (codeTime); return;} timeStr = "(" + timeSec+ ") get mailbox registration code"; $("# code_send_btn") .html (timeStr); timeSec--;}, 1000) } Thank you for your reading, the above is the content of "how to achieve timer function in jQuery".
