• 关于移动手机端富文本编辑器qeditor图片上传改造


      日前项目需要在移动端增加富文本编辑,上网找了下,大多数都是针对pc版的,不太兼容手机,当然由于手机屏幕小等原因也限制富文本编辑器的众多强大功能,所以要找的编辑器功能必须是精简的。

      找了好久,发现qeditor比较精简,操作简单,唯一缺点是上传图片时只能填写url,不能直接从手机上传。

      针对这点,自己决定动手修改。

      修改思路:

        1、创建文件上传输入框

        2、点击编辑器上传图片按钮时,触发文件输入框点击事件

        3、选择图片后异步上传至服务器,返回图片路径

        4、编辑器插入img标签,显示图片

      

      以下是修改过程:

      上图了解下原来是怎么样的,这个是qeditor的界面,qeditor的样式可以自己修改:

      

      点击上传图片按钮后是弹框要求输入图片url的 :

      

      以下是改造后的效果,点击图片上传按钮显示的是现在手机相册图片 :

      选择后上传图片:

      qeditor的代码只有200多行,相当简洁,以下是原始代码:

        $("textarea").qeditor();
    
    and then you need filt the html tags,attributes in you content page.
    In Rails application, you can use like this:

    View Code

      在这里我就不解读其它的代码功能了,主要讲解下修改部分:

      1、在window.QEditor的action方法中有一处判断是否点击图片上传按钮的

    else if (a === "insertimage") {
          p = prompt("Image URL:");
          if (p.trim().length === 0) {
            return false;
          }
        }

      从这里入手,根据思路进行相应改造

    else if (a === "insertimage") {
            //p = prompt("Image URL:");
            var input;
            if(document.getElementById('inImgId')){
                input = document.getElementById('inImgId');
            }else{
                input = document.createElement('input');
                input.setAttribute('id', 'inImgId');
                input.setAttribute('type', 'file');
                input.setAttribute('name', 'file');
                input.setAttribute('accept', 'image/gif, image/jpeg, image/jpg, image/png');
                document.body.appendChild(input);
                input.style.display = 'none';
            }
            input.click();
            input.onchange = function(){
                if(!input.value){return;}
                var fd = new FormData();
                var file;
                file = input.files[0];
                fd.append('file', file);
                $.ajax({
                        url : window.location.protocol + '//' + window.location.host + '/weixin/uploadArticlePic',
                        data : fd,
                        processData : false,
                        contentType : false,
                        enctype : 'multipart/form-data',
                        type : 'POST',
                        success : function(data) {
                            var json = JSON.parse(data);
                            if (json.success) {
                                QEditor.imageChange(json.data);
                            } else {
                                alert(json.message);
                            }
                        }
                    });
            }
          if (p == null || p.trim().length === 0) {
            return false;
          }
        }

    注意到代码中上传图片成功后执行的 QEditor.imageChange(json.data)方法。

     这是我加上去的,目的是使编辑器插入图片,并改变编辑器的值(注意qeditor是由textarea和预览div组成,插入图片是插入到预览div中,并不存在textarea中,而取值却是从textarea中取,所以原作者以增加change()方法解决此问题,本人加入的QEditor.imageChange(json.data)同样是为解决这个问题)

    imageChange: function(imgUrl) {
        var editor = $(".qeditor_preview", $(".qeditor_border"));
        editor.focus();
        document.execCommand("insertimage", false, imgUrl);
        QEditor.checkSectionState(editor);
        editor.change();
      }

    至此修改完毕。

    经测试。。。。

    出现各种各样问题。。。。。图片旋转的、ip4拍照闪退、图片过大等。。。

    后续优化:

      1、加入图片压缩,减少服务器带宽压力

      2、解决图片旋转问题

      3、加入进度条

      4、等
