我怎样才能在 j获得投入要素的价值?
如果是<条码>文本箱:
<input type="text" id="mytextBox" value="" />
您将使用文本箱ID=mytextBox。
var value = $("#mytextBox").val()
$("#elementId").val()
使用<代码>val()功能的最佳方式如下:
$( #someInput ).val();
你们也可以利用权宜之计,找到某些领域的价值。
$( #someInput ).attr( value );
<代码>val功能得到或确定了投入领域的价值。
3. 为“世界”确定投入价值:
$( #myInput ).val( Hello world );
获取投入价值:
$( #myInput ).val();
利用j Query(投入Element ).val()获取投入(格式)要素的价值
