[JavaScript知识库]后端返回JSON数据格式，前端根据JSON数据 导出.CSV文件

以下仅供参考~
效果图

/**
 * 前端JSON导出CSV文件
 * @param {Object} dataObj 对象
 * title:["名称"],
 * jsonKey:["Name"],//键值对 key
 * data: JSON数据,
 * fileName: 文件名
 */
function exportCvs(dataObj) {
	var title = dataObj.title;
	var jsonKey = dataObj.jsonKey;
	var data = dataObj.data;
	var str = [];
	str.push(dataObj.title.join(",") + "\n");
	for (var i = 0; i < data.length; i++) {
		var temp = [];
		for (var j = 0; j < jsonKey.length; j++) {
			temp.push(data[i][jsonKey[j]]);
		}
		str.push(temp.join(",") + "\n");
	}
	var uri = 'data:text/csv;charset=utf-8,\ufeff' + encodeURIComponent(str.join(""));
	var downloadLink = document.createElement("a");
	downloadLink.href = uri;
	downloadLink.download = new Date().toISOString().substring(0, 10) + "-" + dataObj.fileName + "数据明细.csv";
	document.body.appendChild(downloadLink);
	downloadLink.click();
	document.body.removeChild(downloadLink);
};

var data = [
	{
		id: "1",
		Name: "张三",
		age: "23"
	},{

		Name: "小明",
		age: "12"
