jeecg3.8在子表页面中使用WebUploader组件

bcAbout-update.jsp改动如下：

因为默认子表的上传组件不能回显，所以改造成WebUploader

　　1.在更新页面注销掉生成代码

<%--<script type="text/javascript">--%>
 <%--$(document).ready(function(){--%>
<%--$('#tt').tabs({  此段代码会造成子页面重复加载，导致回显异常且验证失效，第一次加载代码的位置未知。--%>
   <%--onSelect:function(title){--%>
       <%--$('#tt .panel-body').css('width','auto');--%>
   <%--}--%>
<%--});--%>
<%--$(".tabs-wrap").css('width','100%');--%>
 <%--});--%>
<%--</script>--%>

<t:tabs id="tt" iframe="false" tabPosition="top" fit="false">
 <t:tab href="bcAboutController.do?bcAboutSubList&id=${bcAboutPage.id}" icon="icon-search" title="***团队" id="bcAboutSub" ></t:tab>
</t:tabs>

2.附表明细 模版 默认组件位置替换为WebUploader组件的模板

<%-- 上传组件模板start --%>
<link rel="stylesheet" type="text/css" href="plug-in/webuploader/custom.css">
<div id="bcAboutSubList_indeximgUrluploader" class="wu-example">
    <div id="bcAboutSubList_indeximgUrlthelist" class="uploader-list">

    </div>
    <div id="bcAboutSubList_indeximgUrl_progress_bar" class="progress-bar-ty " style="display:none">
        <div class="progress-ty">
            <span class="upload-label-ty" style="display:none;">正在加载...<b class="value">79%</b></span>
        </div>
    </div>
    <div class="btns">
        <div id="bcAboutSubList_indeximgUrlpicker" class="webuploader-container">
            选择文件
        </div>
        <%--<input nullmsg="请上传专家图片" datatype="*" type="hidden" id="bcAboutSubList_indeximgUrldataTypeInp">--%>
    </div>
</div>
<div id="tempdiv_bcAboutSubList_indeximgUrl" class="tempIMGdiv"></div>
    <%-- 上传组件模板end --%>

3.添加表单提交前的方法，用于修正新增行的name名称，否则提交报错

<t:formvalid formid="formobj" dialog="true" usePlugin="password" layout="table" tiptype="1" action="bcAboutController.do?doUpdate" beforeSubmit="fixImgData" callback="jeecgFormFileCallBack@Override">

function fixImgData() {
          // 将上传组件图片的name下标修正再提交表单
          resetTrNum('add_bcAboutSub_table');//此方法jeecg自带，用于修正行顺序改变后元素的name属性值
      }

bcAboutSubList.jsp子表页面修改如下：
　　1.定义组件默认js，和计数全局变量（看着长，其实是默认组件生成的，生成后拷贝过来即可，注意js需改一个位置TODO那里）

       "    return rnd;\n" +
       "}";

   var imgId=0;//用于标记子记录上传组件id

　　2，修改添加和减少子表记录的方法

//添加子表记录
$('#addBcAboutSubBtn').bind('click', function(){   
       var tr =  $("#add_bcAboutSub_table_template tr").clone();
    $("#add_bcAboutSub_table").append(tr);
    //修正name的值
       resetTrNum('add_bcAboutSub_table');//jeecg自带
       //处理上传组件WebUploader，id加上“_”前缀，用于区别
       resetTrIdAdd('add_bcAboutSub_table',"_"+(++imgId));//替换模板元素
       var temp = code.replace(/_index/g, "_"+imgId );//替换js
   //添加相应的上传js代码
       loadScriptString(temp,"s"+(imgId));
    return false;
   });

//删除子表记录
$('#delBcAboutSubBtn').bind('click', function(){
    var selectNum=$("#add_bcAboutSub_table").find("input[name$='ck']:checked");
       if(selectNum.length>0){//仅当有选中才操作
           selectNum.parent().parent().remove();//删除对应行

      if(imgId>0){//有添加过
          for(i=0;i<imgId;i++){
                   deleteScriptString("s"+(imgId-i));//删除对应js（文档中）,删除非新增的行时，也会删除新增行对应的js代码，但该代码已经加载至内存中，所以删除动作并无影响。（加载到内存中的js代码无法删除，所以有内存泄漏的风险，单个页面不建议大量使用，或者自行添加限制代码）
         }
      }

      //因tr顺序改变，修正name属性值
           resetTrNum('add_bcAboutSub_table');//jeecg自带
       }

       return false;
   }); 
　　
　　3.增加和删除用到的自定义方法

//增加记录时修改模板中id的值
   function  resetTrIdAdd(tableId,imageId) {

       $("#"+tableId + " tr").each(function(i) {

           $(this).find("div").each(function() {//处理div的id

               var $this = $(this), id = $this.attr('id'), val = $this
                   .val();
               if (id != null && id.indexOf("_index") >= 0) {
                   $this.attr("id", id.replace('_index', imageId));
               }
           });
           $(this).find("input").each(function() {//处理input的id
               var $this = $(this), id = $this.attr('id'), val = $this
                   .val();
               if (id != null && id.indexOf("_index") >= 0) {
                   $this.attr("id", id.replace('_index', imageId));
               }
           });
       });

   }

function loadScriptString(code,idName) {//动态添加js代码，指定id
    var script = document.createElement("script");
    script.type = "text/javascript";
    try {
        script.appendChild(document.createTextNode(code));
    } catch (ex) {//兼容ie
        script.text = code;
    }
    script.id=idName;//指定id
    document.body.appendChild(script);
}

function deleteScriptString(idName) {//根据id动态删除js代码
    var s=document.getElementById(idName);
    if($(s).length>0){//存在才删除，否则报错
        document.body.removeChild(s);
    }
}

总算是能用了，改得超累，有更方便快捷方法的大神还请不吝赐教，写错的地方也希望大家帮忙指出，我会第一时间修改，多谢~
