javascript导出csv

只是记录一下 没啥好说的！ 直接上代码吧！

var csvApp = {
        exportCsv: function(data, name) {
            var uri = 'data:text/csv;charset=utf-8,\ufeff' + encodeURIComponent(data);
            var downloadLink = document.createElement("a");
            downloadLink.href = uri;
            downloadLink.download = (name+".csv")||"temp.csv";
            document.body.appendChild(downloadLink);
            downloadLink.click();
            document.body.removeChild(downloadLink);
        },
        exportTable: function(selector, name) {
            if (document.querySelectorAll(selector).length == 0) {
                alert('Selector "'+selector+'" not exists!');
                return false;
            }
            this.exportCsv(this.tableData(selector), name);
        },
        tableData: function(selector) {
            var data = "";
            var tmp = [];
            document.querySelectorAll(selector+' tr').forEach(function(t) {
                tmp = [];
                t.querySelectorAll('th,td').forEach(function(e){
                    tmp.push(e.innerText.replace("\n", ""));
                });
                data += tmp.join(",") + "\n";
            });
            return data;
        }
    };
// 直接导出数据
    csvApp.exportCsv("wgc,123456,456789,126345","test");
// 导出表格
    csvApp.exportTable("#table_id", "test_1");
// 脚本生成
	var tmp = [];
	var data = "姓名,性别,电话\n";
	for(var i=0;i<10000;i++){
		tmp = [];
		tmp.push('我是'+i+"号");
		tmp.push("男");
		tmp.push('182252'+i);
		data += tmp.join(",") + "\n";
	}
	csvApp.exportCsv(data,'test');
