## **To be myself, forever** ##

**获取src后面的参数**

function getURLParameter(name) { 
       var param = decodeURIComponent((new RegExp('[?|&]' + name +          '=' + '([^&;]+?) (&|#|;|$)').exec(location.search) || [ , "" ])[1]
                    .replace(/\+/g, '%20'))
                    || null;
            return param == "undefined" ? "--" : param;
        }
        alert(getURLParameter("ZD_WorkBillID"));

**重载iframe**

window.frames["Main"].location.reload();

**将undefined转换成”“**

**显示iframe里面的元素**

var ifr = document.getElementById("left");
    ifr.contentWindow.$("#customplan").show();

**取字符串前10个**

var LG_LoanDate=rptdata.data[i].LG_LoanDate.substr(0,10);

**在src后拼参数**

$("#daizhangyuanyin_a").attr("href","../../view/zcgl/daizhangyuanyin.jsp?ZI_ApplyBillID="+ZI_ApplyBillID+"&"+"checktype="+checktype+"&"+"ZI_WriteOffBillID="+ZI_WriteOffBillID);

**下拉框**

$("#selectbutton1r").find("option:selected").val();

**还原下拉框**

mytable=$("#new_dataCustom")[0];
    numone=obj.parentNode.parentNode.rowIndex;
    
    var select=document.getElementById("sex");
    var index=select.selectedIndex//当前坐标
    var option=select.options[index];
    if(mytable.rows[numone].cells[2].innerHTML==""){
       select.options[0].selected=true;
    }else{
       option.text=mytable.rows[numone].cells[2].innerHTML;
    }

**导航（head）**

$(obj).addClass("changePage");
    $(obj).siblings("li").each(function() { 
                $(this).removeClass();
            });

**返回**

function onback(){ 
        history.back();
        }

**拼id**

id='"+rptdata.data[i].ZI_ApplyBillID+"_"+rptdata.data[i].ZI_WriteOffBillID+"'
    ZI_WriteOffBillID_str=this.id.split("_")[1];
    id='remark_"+(i+1)+"' 
    var SD_Remak=$("#remark_"+id).val();

**清除a标签的焦点**

a.hidefocus {outline: none;}
    <a class="hidefocus" hidefocus href="../../view/bbgl/baseinfo.jsp" id="baseinfo2" target="infoInput">
