1、亂碼截圖
我是用的Ajax請求，附上解決辦法：
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="' . $name . '.xlsx"');
header('Cache-Control: max-age=0');
$writer = new Xlsx($spreadsheet);
ob_start(); //打開緩衝區
$writer->save('php://output'); //這裏就是亂碼
// 接收並處理
$xlsData = ob_get_contents();
ob_end_clean(); // 清除緩衝
$response = array(
'code' => '1',
'file' => "data:application/vnd.ms-excel;base64,".base64_encode($xlsData),
'msg'=>'導出成功'
);
return json_encode($response);
附上全部代碼：
1、html部分：
<div class="center mb10">
<form class="layui-form " method="post">
<div class="layui-input-inline w150">
<select name="status" id="sel">
<option value="">選擇狀態</option>
<option value="0" {if condition="$param['status'] eq '0'"}selected {/if}>未審覈</option>
<option value="1" {if condition="$param['status'] eq '1'"}selected {/if}>已審覈</option>
</select>
</div>
<div class="layui-input-inline w150">
<select name="group" id="group">
<option value="">選擇會員組</option>
{volist name="group_list" id="vo"}
<option value="{$vo.group_id}" {if condition="$param['group'] eq $vo.group_id"}selected {/if}>{$vo.group_name}</option>
{/volist}
</select>
</div>
<div class="layui-input-inline">
<input type="text" autocomplete="off" value="{$start_time}" id="datetimeStart" readonly class="form_datetime layui-input" name="start_time" placeholder="請選擇開始時間" />
</div>
-
<div class="layui-input-inline">
<input type="text" autocomplete="off" value="{$end_time}" id="datetimeEnd" readonly class="form_datetime layui-input" name="end_time" placeholder="請選擇結束時間" />
</div>
<div class="layui-input-inline">
<input type="text" autocomplete="off" placeholder="請輸入搜索條件" class="layui-input" name="wd" value="{$param['wd']}">
</div>
<button class="layui-btn mgl-20 j-search" >查詢</button>
<button class="layui-btn mgl-20" type="button" id="btnExport" onclick="excel()">導出</button>
</form>
</div>
2、JS部分：
//Excel導出事件
function excel()
{
var status = $("#sel option:selected").val();
var group = $("#group option:selected").val();
var start_time = $('#datetimeStart').val();
var end_time = $('#datetimeEnd').val();
$.ajax({
url: "{:url('admin/user/export')}",
data: {
status:status,
group:group,
start_time:start_time,
end_time:end_time
},
type: 'post',
dataType: 'json',
success: function (ret) {
var $a = $("<a>");
$a.attr("href",ret.file);
$("body").append($a);
$a.attr("download","file.xls");
$a[0].click();
$a.remove();
if (ret.code == -1) {
alert(ret.msg);
} else if (ret.code == 1) {
window.location.href = "{:url('admin/user/data')}";
}
},
error: function () {
alert('請求失敗，請刷新重試！');
}
})
}
3、封裝部分Excel導出：
<?php

$data[] = $arr;
}
$result = $this->exportExcel($name,$data,$head,$key);
die($result);
}else{
die(json_encode(array('code'=>-1,'msg'=>'導出失敗，請刷新重試')));
}
}

public function exportExcel($name, $data=[], $head=[], $keys=[]){
$count = count($head); //計算表頭數量
$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
for ($i = 65; $i < $count + 65; $i++) { //數字轉字母從65開始，循環設置表頭：
