批量打印，复杂数据结构的批量打印之解决方案

批量打印，复杂数据结构的批量打印，这个问题曾深深地困扰着我一周多的时间，最终得以解决！解决方案记录如下:

1.window setTimeout异步调用函数［异步get+ Window.print()］;

<script>
    //全选/全不选功能
    $(document).on("click",".all_ckx",function () {
        if ($(this).is(":checked")) {
            $("[name=family_id]:checkbox").prop("checked", true);
        } else {
            $("[name=family_id]:checkbox").prop("checked", false);
        }});
    //批量打印功能按钮    获取到每个选中的复选框的值，用get同步请求拿回页面内容存入隐藏的div后，用该div的内容替换掉body中的所有内容进行打印，打印之后再换回原内容
    $("#print").click(function(){
        setTimeout(()=>{
            //获取每个已选中的复选框的值并调用get同步请求回页面数据后，追加到隐藏的div中
            $("input[name='family_id']:checked").each(function(){
            var family_id = $(this).val();
            var n=family_id.indexOf('&');
            var bid = family_id.substring(0,n);
            var type = family_id.substring(n+1);
            $.ajax({
                    async:false,
                    type:'get',
                    url:'{:url('index/Persondata/createprint')}',
                data:{
                    bid:bid,
                    type:type,
                    bill_jump:1
            },
            success:function(data){
                $("#js_print_content").append('<div style="page-break-after:always;">'+data+'</div>');
            }});
        });
        //获取隐藏div中的内容
        var newstr = $("#js_print_content").html();
        //用隐藏的div中的内容替换掉当前页面上的内容
        var oldstr = $("body").prop("outerHTML");
        $("body").html(newstr);
        setTimeout(()=>{
            //调用打印功能
            window.print();
        //返回之前的内容页面
        location.reload();
        //清空隐藏的div中的内容
        $("#js_print_content").html("");
    });
    });
    });

    function printpage() {
        var lodopprint=$("#lodopprint");
//        LODOP.print();

        LODOP=getLodop();
        LODOP.PRINT_INIT("");
        AddPrintContent(lodopprint);
        LODOP.PRINT();
    }
</script>

2.复杂数据结构采用hereDoc语法结构，function回调函数data回调;

 public  function createprint( ){
        $param=input('get.');
        if($param){
            $membermodel=new Members();
            $areamodel=new Area();
            $family_id=$param['type'];
            $family=model('Family')->where('family_id',$family_id)->find();
            $area_id=$family['area_id'];
            $cunarea=$areamodel->where('id',$area_id)->field('area,pid')->find();
            $village=$cunarea['area'];
            $town=$areamodel->where('id',$cunarea['pid'])->value('area');
            $host =  $membermodel->where('id', $family['host'])->value('fullname');
            $members=$membermodel->where('family_id',$family_id)->select();
            $members=collection($members);
            foreach ($members as $key=>$v){
                $members[$key]['outOfPoverty'] = $area_id=$family['outOfPoverty'];
                $members[$key]['year'] = $area_id=$family['year'];
            }
            $memberstring='';
            foreach ($members as $v){
                $memberstring.=  '<tr><td>'.$v['fullname'].'</td><td>'.$v['sex'].'</td><td>'.$v['identity'].'</td><td>'.$v['relation'].'</td><td>'.$v['outOfPoverty'].'</td><td>'.$v['year'].'</td></tr>';
            }
            $education=model('education')->where('family_id',$family_id)->select();
            if(!empty($education)) {
                foreach ($education as $key => $v){
                    $education[$key]['fullname']=$membermodel->where('id',$education[$key]['member_id'])->value('fullname');
                }
            }
            $edustring='';
            if(!empty($education)){
                foreach ($education as $v){

                }
            }else{
                $edustring.=  '<tr><td colspan="6">没有数据</td></tr>';
            }
            $job=model('job')->where('family_id',$family_id)->select();
            if(!empty($job)) {
                foreach ($job as $key => $v) {

            if(!empty($insure)){
                foreach ($insure as $key => $v){
                    $insure[$key]['fullname']=$membermodel->where('id',$insure[$key]['member_id'])->value('fullname');
                }
            }
            $insurestring='';
            if(!empty($insure)){
                foreach ($insure as $v){

3.jquery清空打印容器，回调数据循环填充打印！
