The form is automatically submitted after the validation returns true before the form is submitted

只有在submit按钮加onreturn 才可

<form:form action="save.do" method="post">
                <table class="table1 mTBLR_10_40" >
                    <tr>
     
                  <th colspan="4" class="fbk_th">用户信息</th>
                    </tr>
<div class="searchBtns">
                    <!--   <input type="submit" class="btn btn_green" value="提 交" /> -->
                    <input type="hidden" name="id" value="${roledetl.id}"/>
                    <input type="submit"  class="btn" value="提 交" onclick="return check()"/>
                    <input type="button"  class="btn" value="返 回" onclick="window.history.go(-1);"/>
               </div>
        </form:form>
