if(this.form.newPWD!=this.form.confirmPWD){ this.$message.error("两次输入的密码不一致，请重新输入！"); this.form.newP

This code checks if the value of the "newPWD" field in a form is equal to the value of the "confirmPWD" field. If they are not equal, it displays an error message and clears both fields. The "return" statement stops the execution of the function.
