依据特性投入的扩大案文箱
原标题:Growing text box based on width of characters input

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)"/>
最佳回答

Try size &length und clientWidth &width

rel=“noretinger”>http://jsfiddle.net/eVd9b/5/

function MakeWidth(el) {
    el.size = parseInt(el.value.length);
}

这应适合你们的需要。

问题回答

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。
