我正试图制造一个文字箱,每当一纸空文添加一封信时,就增长。 这是我所尝试的。 它没有工作。 如果是你,请分享!
Java:
function MakeWidth(el) {
el.style.width = parseFloat(el.value.clientWidth) }
HTML:
<input id="Test" type="text" style="width: 10px;" onkeyup="MakeWidth(this)"/>

Try size
&length
und clientWidth
&width
function MakeWidth(el) {
el.size = parseInt(el.value.length);
}
这应适合你们的需要。
使用<代码>size属性可能更为有用。
<input id="Test" type="text" size="1" onkeyup="MakeWidth(this)"/>
<script>
function MakeWidth(el) {
el.size = el.value.length
}
</script>
这是一种bit笑,因为你不一定知道每一种特性的阴.。 想到的一个小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小.,可以试图制造一种隐蔽的四块,使其 s脏,在文字箱中添加,摧毁隐藏的四块。
