php - 如何隐藏动态生成的输入标签和归档

Question

我正在使用 php mvc。它有一个名为 view create 的文件，它从 mysql 数据库中获取指定的表并为其生成一个表单。

如何隐藏特定字段和标签。

该字段在数据库中被称为 allowed，当生成 html 时，它的 id 是 input_allowed。

提前致谢。

编辑:该字段已使用 #input_allowed{display:none;} 隐藏，但标签(名为 allowed 的文本，实际上不是标签，但显示在 a 内)仍在显示。

这是 view_create.php 文件的代码。

<?

    $class_obj=$_REQUEST['class_obj'];

    echo "<p class='p1'>Create new ".$class_obj."</p>";
    if (isset($_REQUEST['post_create']))
    {
        post_create_message($_REQUEST['post_create'],$class_obj);
    }


    echo "<table class=table1><form id=form_create action=".$current_file_name."?here=".$here."&mode=confirm_create&class_obj=".$class_obj." method=post>";

    $w_columns = MyActiveRecord::Columns($class_obj);
    foreach($w_columns as $wcolumns_key => $wcolumns_value)
    {
        if ($wcolumns_key != "id")
        {
            //if($wcolumns_key == "date")
            if(MyActiveRecord::GetType($class_obj,$wcolumns_key) == 'date')
            {
                echo "<tr><td>".$wcolumns_key."<td><input type=text id='input_".$wcolumns_key."' name='input_".$wcolumns_key."' value=''>";
                echo "<td><input type=button value='Set Date' onclick=displayDatePicker('input_".$wcolumns_key."',false,'ymd','-'); >";

                //echo "<tr id='arow'><td>".$wcolumns_key."<td><input type=text id='input_".$wcolumns_key."' name='input_".$wcolumns_key."' value='' datepicker='true' datepicker_format='DD/MM/YYYY'>";
                //echo "<tr><td>".$wcolumns_key."<td><input type=text id='input_".$wcolumns_key."' name='input_".$wcolumns_key."' value='' datepicker='true' datepicker_format='DD/MM/YYYY'><td><div id='aaa'>&nbsp;</div><script>var b = new free_date_picker('b', 'aaa', 'input_".$wcolumns_key."', 1, true, 'en');</script>";




            }
            else

将文本包裹在一个跨度内，并为跨度和输入指定一个唯一的类名(例如，“hideme”)。这样，您在使用 CSS 时会获得一点灵 active 。如果出于某种原因您不能使用某个类，则将“display:none”添加到 span 中就可以解决问题。
