小编Chr*_*gos的帖子

我现在真的很困惑,因为每当我创建一个带有空白活动的新Android应用程序时,它总是带有fragment_main.xml ...我只是想创建一个没有片段的空白活动...

在第一张图片中,空白活动附带片段布局.

第二个图像显示了创建的fragment_main

现在我真的很困惑...这只发生在将ADT更新到最新版本之后我已经提到过这个帖子:https://stackoverflow.com/questions/22203862/adt-doesnt-create-default-hello-world-but -command-line-does#=

我只想制作一个没有片段视图的空白活动的Android应用程序...

我已经尝试使用date_diff和date_create来获得已经转换为字符串的两个日期的差异.

这是代码:

$date_1 = date_create();
$date_now = date_format($date_1, 'Y-m-d');


//echo $date_now . "\n";
$date=date_create($date_now);
date_add($date,date_interval_create_from_date_string("3 days"));
$date_return =  date_format($date,"Y-m-d");


$diff = date_diff(date_create($date_now), date_create($date_return));

echo $diff;

我收到此错误:

Object of class DateInterval could not be converted to string

如何使用Bootstrap 3模态拟合并制作高图表图表？看起来图表独立于页面的CSS,但我不确定.

我使用Twitter Bootstrap 3创建了一个使用模式的表.奇怪的是它在Firefox和jsFiddle上运行良好但在Google Chrome上运行不正常.

我正在使用数据表与自定义服务器端过滤,搜索和排序...为什么columnFilter()返回错误"TypeError:$(...).DataTable(...).columnFilter不是一个函数"

这是我如何使用columnFilter:

var table = $('#item-table').DataTable({
    ajax: '<?= site_url("price_update"); ?>',
    serverSide: true,
    processing: true,
    paging: true
}).columnFilter();

没有".columnFilter()"的代码工作正常.

我有一个

A PHP Error was encountered

Severity: Warning

Message: require_once(/../scraper_utilities.php): failed to open stream: No such file or directory

Filename: utility_classes/special_price_process.php

Line Number: 3

我只是通过以下方式包含了一个文件 scraper_utilities.php：

require_once('/../scraper_utilities.php');

这是我目前使用的 codeigniter 的文件系统：

编辑：我也试过

 require_once('../scraper_utilities.php');

和

require_once(__DIR__.'/scraper_ci/application/libraries/scraper_utilities.php');

但也没有奏效。

即时通讯使用HTML画布制作应用程序。我尝试使用jquery的.offset（）方法获取画布的偏移量，而且还可以。我的问题是当我尝试将画布放在模式上时，offset（）返回0 ...我如何在boostrap模式内获取画布的正确偏移量？

canvas = document.getElementById('canvas');
context = canvas.getContext('2d');
canvasOffset=$("#canvas").offset();
offsetX=canvasOffset.left;
offsetY=canvasOffset.top;

canvasOffset返回顶部和左侧为零...

我有一个工作计时器,每秒返回一个值

<?php
$timer = "10:00";
?>

<input type="text" value="<?php echo $timer; ?>" id="timer"/>

<script>
$('.ok').click(function() {
  setInterval(function(){

  var timer=$('#timer').val();
  var time = timer.split(":");
  var timer = (parseInt(time[0])*60) + parseInt(time[1]);
  var remaining= (timer)-1;
  var minutes = parseInt( remaining / 60 ) % 60;
  var seconds = remaining % 60;
  $('#timer').val(minutes+":"+seconds);
}, 1000);
 });
</script>

我希望输出显示mm:ss.比如输出是9分1秒,我希望它看起来像09:01而不是9:1

即使我将设置"严格"设置为false,laravel 5.5 group by on single column也不起作用..我已经在mysql工作台中尝试了原始查询并且它工作正常但是我在laravel上有这个错误:

SQLSTATE[42000]: Syntax error or access violation: 1055 'hammer.vehicle.consignor_id' isn't in GROUP BY (SQL: select `vehicle`.*, `vehicle_brand`.`vehicle_brand_name`, `vehicle_model`.`vehicle_model_name`, `vehicle_variant`.`vehicle_variant_name`, `vehicle_model`.`year`, `vehicle`.`vehicle_id` from `vehicle` left join `vehicle_brand` on `vehicle_brand`.`vehicle_brand_id` = `vehicle`.`vehicle_brand_id` left join `vehicle_model` on `vehicle_model`.`vehicle_brand_id` = `vehicle_brand`.`vehicle_brand_id` left join `vehicle_variant` on `vehicle_variant`.`vehicle_model_id` = `vehicle_model`.`vehicle_model_id` group by `vehicle`.`vehicle_id` limit 10 offset 0)

这是导致错误的laravel代码

\DB::table('vehicle')
                    ->select('vehicle.*', 'vehicle_brand.vehicle_brand_name', 'vehicle_model.vehicle_model_name', 'vehicle_variant.vehicle_variant_name', 'vehicle_model.year', 'vehicle.vehicle_id')
                    ->leftJoin('vehicle_brand', 'vehicle_brand.vehicle_brand_id', '=', 'vehicle.vehicle_brand_id')
                    ->leftJoin('vehicle_model', 'vehicle_model.vehicle_brand_id', '=', 'vehicle_brand.vehicle_brand_id')
                    ->leftJoin('vehicle_variant', 'vehicle_variant.vehicle_model_id', '=', 'vehicle_model.vehicle_model_id')
                    ->where($where)
                    ->groupBy('vehicle.vehicle_id')
                    ->paginate(10); …

我想验证jquery函数接收的某个字符串.

这是我到目前为止所取得的成就

var duration=$('#duration').val();

  if(//string validation?) {
      $('.alert-box').html('Please use the correct format');
   }

我想要的字符串格式是mm:ss(持续时间m表示分钟,s表示秒数)所以如果用户只输入m:ss或mm:s,或者如果用户输入一位数分钟或秒,则应该是前面有一个零,如果它是9:00然后它应该是09:00.

这是我尝试过的最新代码,但仍然无法验证

 $('#btnAddTestCat').click(function () {
        var code = "addTestCat";
        var test_cat=$('#test_cat').val();
        var duration=$('#duration').val();
        var sub_cat=$('#sub_cat').val();
        var e = $('.alert-box');
        e.slideUp(300);

        if(!(/[0-5][0-9]:[0-5][0-9]/g).test(duration)){
          e.html('Please use the correct format!');
          return false;
        }
        var dataString = 'test_cat=' + test_cat + '&duration=' + duration + '&sub_cat=' + sub_cat + '&code=' + code;
        $.ajax({
            type: "POST",
            url: "controller/category_controller.php",
            data: dataString,
            cache: false,
            success: function(result){
                var result = $.trim(result);
                if(result=='success'){                      
                    e.removeClass("alert");
                    e.addClass("info");
                    e.html('Category added!'); …
