datagrid里的js这么写

//点击添加按钮触发

function superadd(title,addurl,gname,width,height) {
    gridname=gname;
    createwindow(title, addurl,width,height);

}
//点击修改按钮触发
function superupdate(title,url, id,width,height,isRestful) {
    gridname=id;
    var rowsData = $('#'+id).datagrid('getSelections');
    if (!rowsData || rowsData.length==0) {
        tip('请选择编辑项目');
        return;
    }
    if (rowsData.length>1) {
        tip('请选择一条记录再编辑');
        return;
    }
    if(isRestful!='undefined'&&isRestful){
        url += '/'+rowsData[0].id;
    }else{
        url += '&id='+rowsData[0].id;
    }
    createwindow(title,url,width,height);
}
//写一个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：弹出bug修改,设置了zindex()函数
