<select id="edit-attributes-1"></select>
<select id="edit-attributes-2"></select>
<select id="edit-attributes-3"></select>
<select id="edit-attributes-4"></select>
这是由cms生成的,我无能为力
JQUERY:
$('select[id^="edit-attributes-"][id!="edit-attributes-12"]').after('<span class="step stepdown step-'+$(this).attr('id')+'">+</span>');
所以我创建了这个,因为尝试jquery.ui.spinner在识别元素方面存在问题.
注意:
$(this).attr('id') here results as unknown.
结果
<select id="edit-attributes-1"></select>
<span class="step stepdown step-**unknown**">+</span>
<select id="edit-attributes-2"></select>
<span class="step stepdown step-**unknown**">+</span>
<select id="edit-attributes-3"></select>
<span class="step stepdown step-**unknown**">+</span>
<select id="edit-attributes-4"></select>
<span class="step stepdown step-**unknown**">+</span>
正如你所看到的那样,$(this).attr(‘id’)的部分是未知的.
期望的结果
<select id="edit-attributes-1"></select>
<span class="step stepdown step-**edit-attributes-1**">+</span>
<select id="edit-attributes-2"></select>
<span class="step stepdown step-**edit-attributes-2**">+</span>
<select id="edit-attributes-3"></select>
<span class="step stepdown step-**edit-attributes-3**">+</span>
<select id="edit-attributes-4"></select>
<span class="step stepdown step-**edit-attributes-4**">+</span>
我不知道如何才能实现这种概念,或者请提供一种如何简化事物的最佳方法.
最佳答案 这在您的代码中没有引用您选择的元素,您可以使用after函数:
$('select[id^="edit-attributes-"][id!="edit-attributes-12"]').after(function(ind){
return '<span class="step stepdown step-'+ this.id +'">+</span>'
});
