我使用的是组合框，而且我没有像ReadOnly这样的价值。
如何阻止在此组件中输入任何标志的可能性。
我尝试了类似OnKeyPress
if Key in ['a'..'z', 'A'..'Z'] then
Key := #0
答案 0 :(得分：6)
将组合框的<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="style.css">
<script src="script.js"></script>
<style>
/* this will be applied to the images */
.smallicon {
width: 16px;
padding: 5px;
}
</style>
</head>
<body>
<p>
Problem exists in Internet Explorer only
<br> This is fine:
</p>
<object class="smallicon icon-white" data="http://konradpapala.beep.pl/test/040__file_delete.svg" type="image/svg+xml"></object>
<table>
<thead>
<tr>
<th>This is not OK, unless we add style = 'width:20px;height:20px' to the td tag, BTW "normal" images, like .png work fine</th>
<th>This doesn't work either:</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<img class='smallicon' src='http://konradpapala.beep.pl/test/040__file_delete.svg'>
</td>
<td>
<object class='smallicon' data = 'http://konradpapala.beep.pl/test/040__file_delete.svg' type="image/svg+xml"></object>
</td>
</tr>
</tbody>
</table>
</body>
</html>
属性更改为Style。然后用户无法在其中键入任何内容。
