如何将js中的值传到后台action中

通过form 表单和隐藏域传值
<script>
var fjmc=window.parent.document.all.fjmctext.value;
document.getElementByIdx_x_x_x("aaa").value = fjmc;

myForm.action="collectionSendToExcel.action";
  myForm.submit();
</scritp>
<form  action="#" id="myFormToExcel" name="myFormToExcel">

<input type="hidden" name="fjmc" id="aaa" />
<input type="text" name="action" />
<input type="submit" value="提交'>
</form>

 

 

通过Ajax传递：

function commit(){
  var myMask = new Ext.LoadMask(Ext.getBody(), {msg: '正在提交数据，请稍后...'});
  myMask.show();
  Ext.Ajax.request({
                form: 'myForm',
                method: 'post',
                success: function(response, option){
                 myMask.hide();
                 var results = Ext.util.JSON.decode(response.responseText);
        var msgs = '【承兑保证操作成功!】'
       
        switch(results.type){
             case '1':
               msgs = '【保证人账号不能为空，操作失败】';
               break;
             case '2':
               msgs = '【访问数据库发生异常，操作失败】';
               break;
         }
                 Ext.Msg.show({
      title:'信息提示',
      modal:false,
      msg: msgs,
      buttons: Ext.Msg.OK,
      fn:function(btn,text){
        if(btn == 'ok'){
          if(results.success){
            comBack(g('SBillType').value);//返回列表
          }
          }
      },
      animEl: 'elId',
      icon: Ext.MessageBox.INFO
     });             
    },
    failure: function(response,option){
       myMask.hide();
       Ext.MessageBox.alert("信息提示","【提交数据超时，请稍候再试...】");
    }
      }); 

}

还有就通过jquery 的ajax
var fjmc=window.parent.document.all.fjmctext.value;
  Ext.Ajax.request({
       url : 'messageReport.action?' + param ,
       method : 'post' ,
       success :　function(response){
       var result = Ext.util.JSON.decode(response.responseText); 
        if(result.flag == 'success'){
         Ext.Msg.alert('系统提示',result.msg,function(){
          Ext.getCmp('requisitionGridId').getStore().reload();
         });
        }else{
         Ext.MessageBox.alert('系统提示',result.msg,function(){
          Ext.getCmp('requisitionGridId').getStore().reload();
         });
        }
       }
      });  

});

第四种方式：

<script type="text/javascript">
function collectionSendToExcel(){
 var billNo=document . getElementById('billNo').value;
 var SOrgCode=document.getElementByIdx_x("SOrgCode").value;
 var account=document . getElementById('account').value;
 var SCustBankCode=document . getElementById('SCustBankCode').value;
 var operType=document . getElementById('operType').value;
 
 
 
  location.href="collectionSendToExcel.action?querybean.billNo=" + billNo+"&customer.SOrgCode"+SOrgCode+"&account.SAccountNo"+account+"&account.SCustBankCode"+SCustBankCode;
       
 

}
</script>
