我有一个 jqGrid我立即从服务器(java)以 JSON 格式获取数据。我想将jqGrid中的数据导出成Excel格式。
直到现在我才看到这个page这让我在 IE 中出现错误 'o.url is null or not an object' grid.import.js
我还看到了this demo在导出按钮的工具提示上显示 Export To Excel 但保存的文件是 xml 格式。
所以我想要任何可以使用 javascript 或 jquery 插件或使用 jqgrid 的内置功能将我的 JSON 字符串转换为 excel 的建议。

最佳答案
您不必使用 Excel 格式导出文件即可将数据导入 Excel。导出为 CSV 通常要容易得多。 CSV 文件应该默认与 Excel 相关联，因此它应该有 Excel 图标和所有内容。我认为 XML 的工作方式相同，但 CSV 格式要轻得多，并且在这种情况下可以完成相同的工作。将 JSON 转换为 CSV 很简单:
var response = JSON.parse(responseJSON).response;
var csv = arrayToCSV(response);
function arrayToCSV(arr) {
var columnNames = [];
var rows = [];
for (var i=0, len=arr.length; i<len; i++) {
// Each obj represents a row in the table
var obj = arr[i];
// row will collect data from obj
var row = [];
for (var key in obj) {
// Don't iterate through prototype stuff
if (!obj.hasOwnProperty(key)) continue;
// Collect the column names only once
if (i === 0) columnNames.push(prepareValueForCSV(key));
// Collect the data
row.push(prepareValueForCSV(obj[key]));
}
// Push each row to the main collection as csv string
rows.push(row.join(','));
}
// Put the columnNames at the beginning of all the rows
rows.unshift(columnNames.join(','));
// Return the csv string
return rows.join('\n');
}
// This function allows us to have commas, line breaks, and double
// quotes in our value without breaking CSV format.
function prepareValueForCSV(val) {
val = '' + val;
// Escape quotes to avoid ending the value prematurely.
val = val.replace(/"/g, '""');
return '"' + val + '"';
}
