我只是一个小问题.我在网上搜索但我没有找到任何东西.
我经常使用print_r或var_dump经常使用 我正在寻找一种方法来正确地显示具有这些方法的数组,具有正确的格式,对齐等...但不是所有在一行上使得它难以理解.
我怎样才能做到这一点？
我正在使用DOMDocument在HTML页面上检索一个特殊的div.
我只想在没有div标签的情况下检索这个div的内容.
例如 :
$dom = new DOMDocument;
$dom->loadHTML($webtext['content']);
$main = $dom->getElementById('inter');
$dom->saveHTML()
在这里,我有结果:
<div id="inter">
//SOME THINGS IN MY DIV
</div>
我只想拥有:
//SOME THINGS IN MY DIV
想法？谢谢 !
我有一个动态创建的画布,因此宽度和高度总是不同的.
我有一个背景图片我想放在这个画布上,所以我只是添加CSS:
canvas { background:url(/URL/background-canvas.jpg) }
但是,我怎么能自动将图像调整到我画布的大小？谢谢 !
我有一个像以下的HTML代码:
<div class="callcenter" style="" data-id="2">
<select class="entityChange">
<option value=""></option>
<option value="8">callcenter1</option>
</select>
</div>
还有一个事件:
$(document).on('change', '.entityChange', function() {
var ficheId = $(this).prev().attr("data-id");
var type = $(this).prev().attr("data-type");
var newUserId = $(this).val();
console.log($(this).prev());
});
我试图在这个事件中检索我的第一个div的归属但我不能用prev().
有任何想法吗 ？
我是successajax请求的处理程序,如:
$.ajax({
type: "POST",
url: "{{ path('getevents') }}",
data: {start: start, end : end},
success: function (data) {
for ( var i = 0; i < data['rdv'].length; i++ ) {
var divRdv = '<div>My div</div>';
$('myElement').append(divRdv);
$(divRdv).draggable(); // THIS DOESN'T WORK
}
},
error: function (xhr, status, error) {
console.log(xhr.responseText);
}
});
所以,在一个循环中,我需要创建一个div divRdv,将这个div附加到myElement,之后,我希望这个div可拖动.
我能怎么做 ？
我试图逐个添加draggable到每个div,有一种方法可以一次添加draggable到多个元素？

<div id="1" style="display:inline-block">MY DIV 1</div>
<div id="2" style="display:inline-block">MY DIV 2</div>
<div id="3" style="display:inline-block">MY DIV 3</div>
<div id="4" style="display:inline-block">MY DIV 4</div>
<div id="5" style="display:inline-block">MY DIV 5</div>
<div id="6" style="display:inline-block">MY DIV 6</div>
所以有了这个，我有 6 个 div，水平对齐在同一条线上。
我想在第二个 div 之后换行，在第四个 div 之后，我想要：
My DIV 1 My DIV 2
My DIV 3 My DIV 4
My DIV 5 My DIV 6
有任何想法吗 ？
我正在使用Laravel开发一个API,我的json响应有问题,例如我有一个函数:
$company = Company::select('name')
->inRandomOrder()
->limit(1)
->get();
return response()->json([
'company' => $company,
]);
有了这个,我在调用我的函数时得到:
{
"company": [
{
"name": "Company Number 1"
}
]
}
为什么我公司之后有阵列？"company": [有没有办法在$company没有对象之前直接返回(在我的示例中命名为company？)
谢谢 !
