Question

我试图使HTML画布全页。在我的代码中，它警告说画布大小=窗口大小，但未显示正确的输出。

这里的HTML - >

rgba(r,g,b,a)

css->

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width">
    <title>Document</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>

    <canvas></canvas>

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
    <script src="main.js"></script>
</body>
</html>

和jquery->

body
{
    margin: 0;
}
canvas
{
    /*border: 1px solid black;*/
    background: green;
}

我已设法解决您的代码。让我解释。太好了，因为在我看来DECLARE @count INT DECLARE @mgrname VARCHAR(20) SET @count = 3 WITH MGRlist as( SELECT DISTINCT Empmanager FROM HR) **SET @mgrname** = SELECT Empmanager FROM ( SELECT ROW_NUMBER() OVER (ORDER BY mgr ASC) AS RowNumber, * FROM MGRlist ) AS RESULT WHERE RowNumber = @count -- FIND THE CURRENT MANAGER NAME和width()就像是set / get函数，我尝试这样做：

height()

代替（您做了什么）：

canvas.width(windowWidth);
canvas.height(windowHeight);

它奏效了。试试吧！
