模糊搜索的实现

要实现模糊搜索的功能，及在模糊搜索框内输入要查询的信息，会在用户基础信息栏显示模糊搜索的结果

以用户名模糊搜索为例

页面上实现点击回车键即可进行搜索的功能

<%@ page language="java" contentType="text/html; charset=UTF-8"%>

        <script type="text/javascript">
        <!--
        //按回车键提交表单信息
        document.onkeydown = function(e){
        if(!e) e = window.event;//火狐中是 window.event
        if((e.keyCode || e.which) == 13){
            var obtnSearch=document.getElementById("xqSelect")
            obtnSearch.focus();//让另一个控件获得焦点就等于让文本输入框失去焦点
          //  obtnSearch.click();
                }
            }
            
            var actionPath = $('#actionPath').val();
            var path = $('#path').val();
            var businessType = $('#businessType').val();
            if(!businessType)
            {
                businessType="userType";
            }
            var jspPath = path+"webPage/sf_tree/infodata.jsp?businessType="+businessType+"&type=";
           // alert(actionPath);
            //alert(path);
            //alert(jspPath);
            userTree(jspPath,actionPath,path);
            
           
            //-->
        </script>

在sf_leftQuery_js里编写模糊搜索的方法

/*
    模糊搜索
    @parm:queryId 点击查询DOM id
*/
function nebulosityQuery(queryId) {
    var cdbh = window.parent.$('#cdbh').val();
    var nebulositySearch = function () {
        
        var cardNo = $("#cardNo").val();
        var codeNebulosity = $("#codeNebulosity").val();
        var nameNebulosity = $("#nameNebulosity").val();
        var addrNebulosity = $("#addrNebulosity").val();
        
        var cardNoNote = $("#cardNo").attr("noteval");
        var codeNote = $("#codeNebulosity").attr("noteval");
        var nameNote = $("#nameNebulosity").attr("noteval");
        var addrNote = $("#addrNebulosity").attr("noteval");
        $("#" + queryId).datagrid({
            queryParams : {
                "queryVo.firstRequest" : false,
                //"queryVo.nebulosity":$("#txtNebulosity").val(),
                "queryVo.codeNebulosity" : codeNebulosity == codeNote ? "" : codeNebulosity,
                "queryVo.nameNebulosity" : nameNebulosity == nameNote ? "" : nameNebulosity,
                "queryVo.addrNebulosity" : addrNebulosity == addrNote ? "" : addrNebulosity,
                "queryVo.yhkh" : cardNo == cardNoNote ? "" : cardNo,
                "treeUtil.fgs" : "",
                "queryVo.cdbh":cdbh,
            }
            
        });
    }
    $("#nebulosity").click(nebulositySearch);
    $('#txtNebulosity').keypress(function (event) {
        onPressEnter(event, nebulositySearch);
    });
}

搜索的实现是依靠准确的sql查询语句来实现，以下为dao层创建查询sql语句的方法
