<input id="search_input" type="text" class="form-control" id="formGroupExampleInput"
                   placeholder="Search Input...">

    $(function () {
       ...
       content = $('#search_input').val();
       type = $('#search_select').val();
       url = "{{ url_for('search',type="+ type +" ,content="+ content +") }}
       ...
    })

@app.route('/search/type/<type>/content/<content>')
def search(type,content):
    return 'ok'

第二点js代码中， url的值并获取不到，请问如何正确传参数给url_for？
