Question

为什么在文本框的中间？这可能真的很简单，但我无法弄清楚

<div class="wrap-input100 bg1">
    <span class="label-input100">Mensagem (Editável)</span>
    <textarea id='mensagem' style="height:200px;" class="input100" type="text" name="mensagem"> 
        <?php 
        $time = date("H");
        $timezone = date("e");
        if ($time < "12") {
            echo "Bom Dia";
        } else if ($time >= "12" && $time < "17") {
            echo "Boa Tarde";
        } else if ($time >= "19") {
            echo "Boa Noite";
        }
        ?> 
    </textarea>
</div>

问题不是出在班上，因为我删除了它，反正它在中间

Answer 1

您的HTML中有空格。这在文本区域中得到说明。一种解决方案是将输出存储在变量中，并删除空白，例如

<?php 
    $time = date("H");
    $timezone = date("e");
    $output = '';
    if ($time < "12") {
        $output = "Bom Dia";
    } else if ($time >= "12" && $time < "17") {
        $output = "Boa Tarde";
    } else if ($time >= "19") {
        $output = "Boa Noite";
    }
?> 
<textarea id='mensagem' style="height:200px;" class="input100" name="mensagem"><?php echo $output; ?></textarea>

<div class="wrap-input100 bg1">
    <span class="label-input100">Mensagem (Editável)</span>
    <?php 
        $time = date("H");
        $timezone = date("e");
        if ($time < "12") {
            $text = "Bom Dia";
        } else if ($time >= "12" && $time < "17") {
            $text = "Boa Tarde";
        } else if ($time >= "19") {
            $text = "Boa Noite";
        }
        ?> 
    <textarea id='mensagem' style="height:200px;" class="input100" name="mensagem"><?= $text ?></textarea>
</div>

尝试一下

Answer 3

您可以尝试以下方法：

DatabaseModel db = new DatabaseModel();

var val = db.Members
            .FirstOrDefault(b => b.Name == "Yordan");
db.Entry(val).State = EntityState.Detached;

var val2 = new Player(val);
val2.Name = "Frank";

db.Members.Update(val2);
db.SaveChanges();

Answer 4

这是由于span标签。使用div代替tag并添加CSS。看到这个

<div class="wrap-input100 bg1">
    <div class="label-input100" style="float:left; margin-right: 5px;">Mensagem (Editável)</div>
    <textarea id='mensagem' class="input100" style="height:200px; width:40% " type="text" name="mensagem"> 
        <?php 
        $time = date("H");
        $timezone = date("e");
        if ($time < "12") {
            echo "Bom Dia";
        } else if ($time >= "12" && $time < "17") {
            echo "Boa Tarde";
        } else if ($time >= "19") {
            echo "Boa Noite";
        }
        ?> 
    </textarea>
</div>

Answer 5

您必须在页面上对其进行检查。右键单击Bom Dia，然后单击检查元素，然后检查其为何居中。可能是因为您输入了100类，还是因为textarea样式。您需要相应地修改它的css。

文字在中间而不是在左边
