提交表单的几种方法

1.   通过提交按钮控制表单提交

  <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" οnclick="return check(this.form)"> 

</form>   

2. 通过form(或input)的onsubmit事件控制提交 

<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" οnsubmit="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>  

3. 通过form对象提交表单

 <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" οnclick="check(this.form)"> 

</form> 

4. 通过javascirpt控制form传值及提交

//增加的函数 begin

function queryFun(){

  var type = $("#artType").val();

  var hasInputed = "1";//表示输入了要搜索 的信息

  if($("#query").val()=="选手姓名/编号"){

    //表示没有输入要搜索的值

    hasInputed="0";

  }

   document.getElementById("queryForm").action="../news/starList.do?inputData="+hasInputed+"&artType="+type;

  document.getElementById("queryForm").submit();

}

//增加的函数 end
