[PHP知识库]php 生成txt文件的两种方式 ajax获取数据和 a 标签请求

a标签请求

html代码：

<a href="地址" ></a>

php代码：

$filename = rawurlencode($filename);
header('Content-Type: "application/octet-stream"');
header('Content-Disposition: attachment; filename="' . $filename . '"');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header("Content-Transfer-Encoding: binary");
header('Pragma: public');
header("Content-Length: " . strlen($text));

echo $text;

ajax请求

php页面就不写了就是给ajax传数据

<button type="button"  class="layui-btn layui-btn-sm layui-btn-primary " onclick="exportTXT()" >导出TXT文件</button>

function exportTXT() {
        var tid = '{$tid}';
        $.get('url',参数,function (res) {
            if (res.code == 0){
                var text = '';
                $.each(res.data,function (index,value) {
                    text += value + '\n';
                })
                console.log(text);
                var element = document.createElement('a');
                element.setAttribute('href', 'data:text/plain;charset=utf-8,' + encodeURIComponent(text));//内容
                element.setAttribute('download', 'HS'+tid+'.txt');//文件名
                element.style.display = 'none';
                document.body.appendChild(element);
                element.click();
                document.body.removeChild(element);

            }else{
                layer.msg(res.msg,{icon:5});
            }

        });
    }
