Question

我将网格数据导出到excel表格，一切都很棒。唯一的问题是我只想包含某些列。仅限以下内容：id，name，assign date，check date，due date，notes。这该怎么做？以下是我到目前为止的情况：

的jqGrid：

$(function(){ 
  $("#list").jqGrid({
    url:'request.php',
    editurl: "jqGridCrud.php",
    datatype: 'xml',
    mtype: 'GET',
    height: 530,
    width: 850,
        scrollOffset:0,



    colNames:['id','Project', 'Assigned To','Assign Date','Check Date','Due Date','Attached','Notes',''],
    colModel :[ 

      {name:'id', index:'id', width:25}, 
      {name:'name', index:'name', width:235, align:'left',editable:true, editoptions:{
            size:60} }, 
      {name:'Assigned to', index:'id_continent', width:55, align:'right',editable:true,edittype:'select', 
      editoptions:{value: "Henry:Henry; Ramon:Ramon; Paul:Paul" },mtype:'POST'  }, 

      {name:'assign date', index:'lastvisit', width:70, align:'right',formatter: 'date',srcformat:'yyyy-mm-dd',newformat: 'm/dd/yy',editable:true, edittype: 'text',mtype:'POST' ,editoptions:{size:10, dataInit:function(elem){$(elem).datepicker({dateFormat:'m/dd/yy'});}}} ,


      {name:'check date', index:'cdate', width:70, align:'right',formatter: 'date',srcformat:'yyyy-mm-dd',newformat: 'm/dd/yy', edittype: 'text',editable:true ,mtype:'POST' ,editoptions:{size:10, dataInit:function(elem){$(elem).datepicker({dateFormat:'m/dd/yy'});}}} ,

      {name:'due date', index:'ddate', width:70, align:'right',formatter: 'date',srcformat:'yyyy-mm-dd',newformat: 'm/dd/yy',editable:true, edittype: 'text',editoptions:{size:10, dataInit:function(elem){$(elem).datepicker({dateFormat:'m/dd/yy'});}}} ,


      {name:'files', index:'email', width:40,align:'center',sortable:false,mtype:'POST', formatter:function(cellvalue, options, rowObject){
            return '<a href="' + cellvalue + '" target="_blank">FILES </a> '
        } },
        {name:'notes', index:'notes', width:100, align:'left',editable:true,edittype:'textarea', editoptions:{
            rows:5,cols:60,maxlength:200} },
        {name:'act',index:'act',width:25 ,align:'left', sortable:false,formatter: "actions",cellattr: function () { return ' title="Delete Project"'; },
formatoptions: {
    keys: true,
    delbutton: true,
    editbutton:false,


    delOptions: {
        url: 'jqGridCrud.php',
        afterShowForm: function ($form) {
    $("#dData", $form.parent()).click();
},
        beforeShowForm: function ($form) {
    $("td.delmsg", $form[0]).html("Do you really want delete the row with <b>id=" +
         $("#list").jqGrid('getGridParam','selrow') + "</b>?");
},
        msg: "Remove Selected Project?",
        bSubmit: "Remove",
        bCancel: "Cancel"
    } 
}}, 


    ],
    pager: '#pager',


    rowNum:20,
    rowList:[20,40,80],
    sortname: 'id',
    sortorder: 'desc',
    viewrecords: true,
    gridview: true,
    caption: 'Pending Assignments',



    ondblClickRow: function(rowid) {

    $(this).jqGrid('viewGridRow', rowid,
                        {width:550,Height:550,recreateForm:true,
                         closeOnEscape:true,reloadAfterSubmit:true, modal:true,mtype:'post',top:350,left: 30});}


            });

$.extend($.jgrid.nav, {delicon: "ui-icon-circle-check", deltext: "Project Complete", 
});

 $("#list").jqGrid("navGrid", "#pager", { add: false, search: false, edit:false, refresh:false }) .navButtonAdd('#pager',{


                                caption:"Export to Excel", 
                                buttonicon:"ui-icon-save", 
                                onClickButton: function(){ 
                                  exportExcel();
                                }, 
                                position:"last"
                            });
  // setup grid print capability. 
    setPrintGrid('list','pager','Print');
    });

Excel导出功能：

  function exportExcel()
    {
        var mya=new Array();
        mya=$("#list").getDataIDs();  // Get All IDs
        var data=$("#list").getRowData(mya[0]);     // Get First row to get the labels
        var colNames=new Array(); 
        var ii=0;
        for (var i in data){colNames[ii++]=i;}    // capture col names
        var html="";
        var filtered = [ 6, 8];
            for(k=0;k<colNames.length;k++)
            { 
            if (filtered.indexOf(k) >= 0)
            {
            html=html+colNames[k]+"\t";     // output each Column as tab delimited
            }
            html=html+"\n"; 
            }                   // Output header with end of line
        for(i=0;i<mya.length;i++)
            {
            data=$("#list").getRowData(mya[i]); // get each row
            for(j=0;j<colNames.length;j++)
                { 
                if (filtered.indexOf(j) >= 0){
             html=html+data[colNames[j]]+"\t"; // output each Row as tab delimited
                }
            html=html+"\n";  // output each row with end of line

            }}
        html=html+"\n";  // end of line at the end
        document.forms[0].csvBuffer.value=html;
        document.forms[0].method='POST';
        document.forms[0].action='csvExport.php';  // send it to server which will open this contents in excel file
        document.forms[0].target='_blank';
        document.forms[0].submit();
    }

服务器上的PHP：

<?php 

header('Content-type: application/vnd.ms-excel');
header("Content-Disposition: attachment; filename=current-projects.xls");
header("Pragma: no-cache");

$buffer = $_POST['csvBuffer'];

try{
    echo $buffer;
}catch(Exception $e){

}

?>

根据您的代码，您只需修改exportExcel即可过滤掉您不想要的列。它可以像您想要从输出中过滤的索引数组一样简单。如果过滤了j或k的当前值，则不要在标头或数据输出中包含该列。

例如，使用indexOf数组函数过滤标题行：

var filtered = [2, 6, 8];
...
for(k=0;k<colNames.length;k++) {
    if (filtered.indexOf(k) >= 0){
        html=html+colNames[k]+"\t";     // output each Column as tab delimited
    }
    html=html+"\n"; 
}

您可以使用相同类型的代码来过滤数据本身。

这有帮助吗？
