YII2可有方法实现下拉框联动?
本来想去yiichina问的,但是上面很水,基本只有站长偶尔回复一下!
就是类似于城市三级联动那种,选中一级之后,在后一个下拉框列出下一级的分类,只是我是用于我的分类。其实用html+js+php我是可以弄出来的,只是这样会抛弃yii
自带的表单生成方法,也会失去他的验证!
暂时先用自己会的方法弄了,如果有大神知道,再改成YII
风格的~

Yii2本身没有联动效果插件,都是用其他类拼接起来的,不过你自己可以写插件。yii2的例子没有,之前写过yii1的联动效果。你不想失去本身的验证,只要input的name跟模型中的一样就行了。
<code>//view <div class="form-group row"> <div class="col-md-1"> <?php echo $form->dropDownList($blog,'mid',CHtml::listData(Metas::model()->parents(),'mid','name'), array ( 'class'=>'form-control', 'empty'=>array('0'=>'请选择类别'), 'onchange'=>'ajaxGetArea(this)')); ?> <?php echo $form->error($blog,'mid'); ?> </div> </div> //js Yii::app()->clientScript->registerScript('metas', ' function ajaxGetArea(obj) { //请求地址 var link = "'.Yii::app()->createUrl("/cms/metas/json").'"; //请求数据 $.post( link, { parent : $(obj).val() }, function(data) { //清除子类的select $(obj).parent().nextAll("div").each(function() { $(this).remove(); }); if (data != "-1") { //构造子类select的html var select = null; // 此处注意添加onchange事件 select = "<div class='\"col-md-1\"'><select class='\"form-control\"' name='\"Articles[mid]\"' onchange='\"ajaxGetArea(this)\"'><option value='\"-1\"'>请选择类别</option>"; $.each(data, function(key, item) { select += "<option value="+item.mid+">"+item.name+"</option>"; }); select += "</select></div>"; //插入到右侧,上一级 $(obj).parent().after(select); //触发下一个子类select的动态加载 //$(obj).next("select").trigger("change", function() { //ajaxGetArea($(this)); //}); //更新name的位置 $(obj).removeAttr("id"); $(obj).next("select").attr("id", "Articles_mid"); $(obj).removeAttr("name"); $(obj).next("select").attr("name", "Articles[mid]"); } }, "json" ); } ',CClientScript::POS_END); </code>
