2. 改变投入规模和分类
原标题:Change the size of input with jquery

我有以下投入:

<input id="input_2_2" 
       class="medium" 
       type="file" 
       tabindex="4" 
       size="20" 
       value="" 
       name="input_2">

因此,我没有机会使用超文本,因此,我要申请格文将体积改为“60”。

请有人帮助?

问题回答

使用:

$("#input_2_2").attr("size", "60");

我认为,这应当奏效。

$ (“input_2_2”).attr(“size”,“60”);

http://api.jquery.com/attr/“rel=“nofollow”>attr(<>

类似:

<input id=“input_2_2” 类别=“medium” 类型=“file” tabindex=“4” 尺寸=“20” 数值=“名称=“input_2”>

$("#input_2_2").attr("size","60");

或者,在我看来,你只能确定该要素的<代码>width

I used .prop

$( #input_2_2 ).prop( size ,60);

As of jQuery 1.6, the .prop() method provides a way to explicitly retrieve property values, while .attr() retrieves attributes.
