Question

我在class Signature { constructor() { this.color = "#000000"; this.sign = false; this.begin_sign = false; this.width_line = 5; this.canvas = document.getElementById('canvas'); this.offsetLeft = this.canvas.offsetLeft; this.offsetTop = this.canvas.offsetTop; this.context = canvas.getContext('2d'); this.context.lineJoin = 'round'; this.context.lineCap = 'round'; this.whenMouseDown(); this.whenMouseUp(); this.whenMouseMove(); this.createSignature(); this.clearCanvas(); this.resetCanvas(); } updateMousePosition(mX, mY) { let rect = this.canvas.getBoundingClientRect(); let scaleX = this.canvas.width / rect.width; let scaleY = this.canvas.height / rect.height; this.cursorX = (mX - rect.left) * scaleX; this.cursorY = (mY - rect.top) * scaleY; }中有多个弹出窗口，其中每个弹出窗口都有许多复选框。我试图获取test.blade.php框的值并将其显示在名为checked的新view中。但是brief没有显示该值。

注意此行：

brief.blade.php

我是laravel / php的新手，对如何传递数据感到困惑。我不清楚。

我看到了这些1 2的答案，但没有帮助。

test.blade.php

<form method="POST" action="{{ url('test/showBrief') }}">

TestController.php

Answer 1

例如，您可以发送数据

return view('brief', ['data' => $data]);

或可以使用紧凑方法（如果名称相同）

return view('brief', compact('data');

然后在刀片中可以像这样使用

{{$data['service']}}

Answer 2

我做错了MATCH (u:USER {name: "John"}) MATCH (a:AGE {name: "28"}) CREATE (u)-[:IS]->(a)方法。

post

这里应该是

<button type="button" onclick="window.location='{{ route("brief") }}'">Close </button>

在button type="submit"中，它将是web.php方法，而不是post。
