--------------------------------js校验表单后提交表单的三种方法----------------------------------
第一种:
<script type="text/javascript"> function check(form) { if(form.userId.value=='') { alert("请输入用户帐号!"); form.userId.focus(); return false; } if(form.password.value==''){ alert("请输入登录密码!"); form.password.focus(); return false; } return true; } </script> <form action="login.do?act=login" method="post"> 用户帐号 <input type=text name="userId" size="18" value="" > <br> 登录密码 <input type="password" name="password" size="19" value=""/> <input type=submit name="submit1" value="登陆" onclick="return check(this.form)"> </form>
第二种:
<script type="text/javascript"> function check(form) { if(form.userId.value=='') { alert("请输入用户帐号!"); form.userId.focus(); return false; } if(form.password.value==''){ alert("请输入登录密码!"); form.password.focus(); return false; } return true; } </script> <form action="login.do?act=login" method="post" onsubmit="return check(this)"> 用户帐号 <input type=text name="userId" size="18" value="" > <br> 登录密码 <input type="password" name="password" size="19" value=""/> <input type=submit name="submit1" value="登陆"> </form>
第三种:
<script type="text/javascript"> function check(form) { if(form.userId.value=='') { alert("请输入用户帐号!"); form.userId.focus(); return false; } if(form.password.value==''){ alert("请输入登录密码!"); form.password.focus(); return false; } document.myform.submit(); } </script> <form action="login.do?act=login" name="myform" method="post"> 用户帐号 <input type=text name="userId" size="18" value="" > <br> 登录密码 <input type="password" name="password" size="19" value=""/> <input type=button name="submit1" value="登陆" onclick="check(this.form)"> </form>
表单验证:
<script type="text/javascript" src="${path}/js/custom/validator.js"></script>
三种结合:
<script type="text/javascript" src="${path}/js/custom/validator.js"></script>
<script language="javascript"> function check(form) { //alert(form.open_date.value); var beginTime = form.open_date.value; var endTime = form.bid_date.value; var beginTimes = beginTime.substring(0, 10).split('-'); var endTimes = endTime.substring(0, 10).split('-'); beginTime = beginTimes[1] + '-' + beginTimes[2] + '-' + beginTimes[0] + ' ' + beginTime.substring(10, 19); endTime = endTimes[1] + '-' + endTimes[2] + '-' + endTimes[0] + ' ' + endTime.substring(10, 19); //alert(beginTime + "aaa" + endTime); // alert(Date.parse(endTime)); // alert(Date.parse(beginTime)); var a = (Date.parse(endTime) - Date.parse(beginTime)) / 3600 / 1000; if (a < 0) { alert("评标时间必须晚于开标时间!"); return false; } else if (a > 0) { //alert("endTime大!"); //document.myform.submit(); } else if (a == 0) { alert("评标时间必须晚于开标时间!"); return false; } else { return false; } return true; } </script>
------------------表单----------------
<form action="${path}/AmAppliaction_add.do" method="post" id="myform" name="myform" onSubmit="return Validator.Validate(this,3)"> <table class="table" cellspacing="0" cellpadding="2" width="99%" align="center" border="0">
<input label="开标时间" id="open_date" name="open_date" value="${open_date}" dataType="Require" msg="开标时间不能为空" class="Wdate" size="10" readonly="readonly" style="height:15px;width: 184px;" onfocus="WdatePicker({dateFmt:'yyyy-MM-dd HH:mm:ss'})" />
<td class="td_bg" align="left" colspan="2"> <input type="submit" name="submit1" value="提交" onclick="check(this.form)"> <s:reset value="重置" cssClass="btn"></s:reset> </td>
</form>
--------------------------验证会先比较时间-------------------然后FORM提交触发JS表单验证------------------------
js日期/时间比较函数,以及js校验表单后提交表单的三种方法,表单验证,以及三种结合
