一百三十八：CMS系统之发布帖子前端js

先补一个功能，根据扥状态显示用户名/退出或者登录/注册

from .views import bp
import config
from flask import session, g
from .models import FrontUser

@bp.before_request
def before_request():
    """ 验证登录 """
    if config.FRONT_USER_ID in session:
        user_id = session.get(config.FRONT_USER_ID)
        user = FrontUser.query.get(user_id)
        if user:
            g.front_user = user

{% if g.front_user %}
  <div class="dropdown">
    <a  href="#" class="dropdown-toggle" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true">
      {{ g.front_user.username }}
      <span class="caret"></span>
    </a>
    <ul class="dropdown-menu" aria-labelledby="dropdownMenu1">
      <li><a href="#">个人中心</a></li>
      <li><a href="#">设置</a></li>
      <li><a href="#">注销</a></li>
    </ul>
  </div>
{% else %}
  <li><a href="{{ url_for('front.signin') }}">登录</a></li>
  <li><a href="{{ url_for('front.signup') }}">注册</a></li>
{% endif %}

发布帖子js

给点击发布按钮寄一个id，方便js绑定事件

js

$(function () {
    //初始化ueditor
    var ue = UE.getEditor('editor', {
        'serverUrl': '/ueditor/upload/'
    });

    $('#submit-btn').click(function (event) {
        event.preventDefault();
        var titleInput = $('input[name="title"]');
        var boardSelect = $('select[name="board_id"]');

        var title = titleInput.val();
        var board_id = boardSelect.val();
        var content = ue.getContent();  //详见ueditor使用说明，获取内容:http://fex.baidu.com/ueditor/#api-common

        ajax.post({
            'url': '/apost/',
            'data': {
                'title': title,
                'content': content,
                'board_id': board_id
            },
            'success': function (data) {
                if(data['code'] == 200){
                    xtalert.alertConfirm({
                        'msg': '发帖成功',
                        'cancelText': '回到首页',
                        'confirmText': '再发一篇',
                        'cancelCallback': function () {
                            // 点回到首页就跳转到首页
                            window.location = '/';
                        },
                        'confirmCallback': function () {
                            // 点再发一篇就清空内容
                            titleInput.val('');
                            ue.setContent('');
                        }
                    });
                }else{
                    xtalert.alertInfo(data['message']);
                }
            }
        });
    });
});
