點擊datagrid彈出ldhdialog，點擊彈出框的按鈕，關閉且刷新datagrid

datagrid里的js這么寫

//點擊添加按鈕觸發

function superadd(title,addurl,gname,width,height) {
    gridname=gname;
    createwindow(title, addurl,width,height);
    
}
//點擊修改按鈕觸發
function superupdate(title,url, id,width,height,isRestful) {
    gridname=id;
    var rowsData = $('#'+id).datagrid('getSelections');
    if (!rowsData || rowsData.length==0) {
        tip('請選擇編輯項目');
        return;
    }
    if (rowsData.length>1) {
        tip('請選擇一條記錄再編輯');
        return;
    }
    if(isRestful!='undefined'&&isRestful){
        url += '/'+rowsData[0].id;
    }else{
        url += '&id='+rowsData[0].id;
    }
    createwindow(title,url,width,height);
}
//寫一個ldhdialog
function createwindow(title, addurl,width,height) {
    width = width?width:700;
    height = height?height:400;
    if(width=="100%" || height=="100%"){
        width = window.top.document.body.offsetWidth;
        height =window.top.document.body.offsetHeight-100;
    }
    //--author：JueYue---------date：20140427---------for：彈出bug修改,設置了zindex()函數
    if(typeof(windowapi) == 'undefined'){
        $.dialog({

function faqi() {
    $('#faqi', iframe.document).click(); //faqi 是個在添加和編輯頁面的一個<a>的id；會觸發編輯頁面中的onclick（）
    window.f_load();//刷新父頁面datagrid
}

function f_load(){
 $('#tPdmisExceptionList').datagrid('reload');
}

編輯頁面jsp

        },
        success: function(result) {
            frameElement.api.reload(frameElement.lhgDG); //回到datagrid頁面的js中的faqi（）
            alert(result.msg);
            frameElement.api.close(); //關閉彈出框dialog
        },
        dataType:'json'
