哪些网站可以做seo网络营销的现状及问题
一、监听单选按钮事件
点击资源类型单选按钮时，请求后台接口，把接口返回的内容追加到选择资源下拉框内
HTML
<div class="layui-form-item"><label class="layui-form-label">资源类型：</label><div class="layui-input-inline" style="width: 50%"><input type="radio" name="kind" lay-filter="kindradio" value="1" title="课件"><input type="radio" name="kind" lay-filter="kindradio" value="2" title="视频"></div>
</div><div class="layui-form-item"><label class="layui-form-label">选择资源：</label><div class="layui-input-inline" style="width: 50%"><select name="public_kejian_id" lay-search="" lay-filter="source" lay-verify="required" id="kejian_opt"></select></div>
</div>JQ
// 监听
form.on('radio(kindradio)',function (data) {// 清空下拉框内容$('#kejian_opt').empty();var section_id = $('[name="section_id"]').val()console.log(data) $.ajax({url:'getKejianVideo',type:'POST',dataType:'JSON',data:{kind:data.value,section_id:section_id},success:function (res) {console.log(res)if (res.code == '200') {if (data.value == '1') {var tag = '课件';}else if (data.value == '2') {var tag = '视频';}var html = "<option value=''>--直接选择或搜索选择--</option>"; $(res.data).each(function (v, k) { html += "<option value='" + k.id + "'>【"+tag+"】"+k.filename+"</option>"; }); //把遍历的数据放到select里面 $("#kejian_opt").append(html);}else{layer.msg(res.message)} //重新刷新了一下下拉框 form.render('select'); }})
})二、监听下拉框事件
HTML
<select name="public_kejian_id" lay-search="" lay-filter="source" lay-verify="required" id="kejian_opt"></select>JQ 获取当前选中的value值和对应的文本
// 监听下拉框
form.on('select(source)',function (data) {console.log('选中的id：'+data.value)var selectedText = data.elem[data.elem.selectedIndex].text;console.log('选中的文字：' + selectedText);
