【问题描述】:
我试图从 SELECT 输入中的 OPTION 中获取两个值...
这是我得到的:
jQuery:
$(document).ready(function() {
$( "#embed-layout-options" ).change(function () {
var widthval = $(this).attr('data-width');
var heightval = $(this).attr('data-height');
var urlcode = "<iframe src='http://videos.enteratenorte.com/embed/"+widthval+"-"+heightval+"/6NExpBjXme' width='"+widthval+"' height='"+heightval+"' frameborder=0 webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe>";
$("#codeemb").val(urlcode);
})
});
HTML:
<input type="text" id="codeemb" style="font-size:18px; width:710px" value="<iframe src='http://videos.enteratenorte.com/embed/720-405/6NExpBjXme' width='720' height='405' frameborder=0 webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe>">
Size:<select id="embed-layout-options">
<option value="0" data-width="560" data-height="315">560 × 315</option>
<option value="1" data-width="640" data-height="360">640 × 360</option>
<option value="2" data-width="720" data-height="405" selected="selected">720 × 405</option>
<option value="3" data-width="853" data-height="480">853 × 480</option>
<option value="4" data-width="1280" data-height="720">1280 × 720</option>
</select>
它确实发生了变化,但不是数字,而是未定义
你可以在这里测试它: http://jsfiddle.net/EnterateNorte/foc085jc/
谢谢!
