form表单中去掉默认的enter键提交并绑定js方法

function dosearch(){       var keywords=$("#s").val();       keywords=encodeURI(keywords);          keywords=encodeURI(keywords);       // window.open("${ctx}/DispatchAction.do?serviceName=SearchWeb&efFormEname=FS01&methodName=query&i-0-page=0&i-0-keywords="+keywords+"&i-0-moduleId=bmoa_badc");         location.href="${ctx}/DispatchAction.do?serviceName=SearchWeb&efFormEname=FS01&methodName=query&i-0-page=0&i-0-keywords="+keywords;     }
