我已经将jqGrid设置为DataTables的替代品,但我遗漏的一个重要部分是导出到Excel的能力。 DataTables使用html5处理这个问题,并使用Flash作为备份方法(我根本不想使用闪存)。
当使用jqGrid搜索一种方法时,我看到几篇很老的帖子,但最近没什么。我正在使用php服务器后端,其中包含来自JSON文件的数据。我看到jqGrid的付费版本有一个php版本。是否有一个与jqGrid的免费版本兼容的方法,我可以用它来导出真正的Excel文件(而不是csv)?

jqGrid的按钮
$grid.jqGrid("navButtonAdd", {
caption: "Export<br />To Excel",
buttonicon: "ui-pg-button-text ui-pg-button-icon-over-text fa-file-excel-o",
title: "Export to Excel",
onClickButton: function () {
exportExcel();
}
});
表单输入的HTML
<form id='_export' method="post" action="jqGrid/export_excel.php">
<input type="hidden" name="csvBuffer" id="csvBuffer" value="" />
</form>
用于导出到Excel功能的JAVASCRIPT
function exportExcel()
{
var keys=[], ii=0, rows="";
var ids=$("#list").getDataIDs();
var row=$("#list").getRowData(ids[0]);
var p = $("#list").jqGrid("getGridParam");
var rows="<table><thead><tr>";
for (var k in row) {
keys[ii++]=k;
rows=rows+'<th>'+p.colNames[ii+1]+'</th>';
}
rows=rows+"</tr></thead><tbody>";
for(i=0;i<ids.length;i++) {
row=$("#list").getRowData(ids[i]);
rows=rows+"<tr>";
for(j=0;j<keys.length;j++){
rows=rows+'<td>'+row[keys[j]]+'</td>';
}
rows=rows+"</tr></tbody>";
}
rows=rows+"</table>";
document.getElementById('csvBuffer').value=rows;
document.getElementById('_export').submit();
}
用于下载XLS文件的PHP
$buffer = $_POST['csvBuffer'];
// file name for download
$filename = "baplie_" . date('Ymd') . ".xls";
header("Content-Disposition: attachment; filename=\"$filename\"");
header("Content-Type: application/vnd.ms-excel");
try{
echo $buffer;
}catch(Exception $e){
}

我正在为我创建的内部网站使用DataTables。我使用这个脚本将表格数据下载到CSV文件,效果很好。您可能需要更改一些内容,以便ID和类与您的表匹配,但请尝试一下。
// export data function
$('#exportDataTable').click(function() {
var titles = [];
var data = [];
/* * Get the table headers, this will be CSV headers
* The count of headers will be CSV string separator */
$('.dataTable th').each(function() {
titles.push($(this).text());
});
/* * Get the actual data, this will contain all the data, in 1 array */
$('.dataTable td').each(function() {
data.push($(this).text());
});
/* * Convert our data to CSV string */
var CSVString = prepCSVRow(titles, titles.length, '');
CSVString = prepCSVRow(data, titles.length, CSVString);
/* * Make CSV downloadable*/
var downloadLink = document.createElement("a");
var blob = new Blob(["\ufeff", CSVString]);
var url = URL.createObjectURL(blob);
downloadLink.href = url;
downloadLink.download = "data.csv";
/** Actually download CSV */
document.body.appendChild(downloadLink);
downloadLink.click();
document.body.removeChild(downloadLink);
});
/** Convert data array to CSV string
* @param arr {Array} - the actual data
* @param columnCount {Number} - the amount to split the data into columns
* @param initial {String} - initial string to append to CSV string
* return {String} - ready CSV string */
function prepCSVRow(arr, columnCount, initial) {
var row = ''; // this will hold data
var delimeter = ','; // data slice separator, in excel it's `;`, in usual CSv it's `,`
var newLine = '\r\n'; // newline separator for CSV row
/* * Convert [1,2,3,4] into [[1,2], [3,4]] while count is 2
* @param _arr {Array} - the actual array to split
* @param _count {Number} - the amount to split
* return {Array} - splitted array */
function splitArray(_arr, _count) {
var splitted = [];
var result = [];
_arr.forEach(function(item, idx) {
if ((idx + 1) % _count === 0) {
splitted.push('"' + item + '"');
result.push(splitted);
splitted = [];
} else {
splitted.push('"' + item + '"');
}
});
return result;
}
var plainArr = splitArray(arr, columnCount);
// don't know how to explain this
// you just have to like follow the code
// and you understand, it's pretty simple
// it converts `['a', 'b', 'c']` to `a,b,c` string
plainArr.forEach(function(arrItem) {
arrItem.forEach(function(item, idx) {
row += item + ((idx + 1) === arrItem.length ? '' : delimeter);
});
row += newLine;
});
return initial + row;
}
// end export to CSV file
