The third project to be speaking with jeecg (Custom Import Export)

1. Import

The front page and jump js

 < T: dgToolBar title = "single template Import" icon = "icon-PUT"     funname = "Importonlyone" > </ T: dgToolBar >

function Importonlyone(title,url,gname) {
    gridname=gname;
    var ids = [];
    var rows = $("#"+gname).datagrid('getSelections'); 
   　if(rows.length==1){
        openuploadwin('Excel导入', 'decMainController.do?upload&num=1&ids='+rows[0].id, "decMainList");
    } 

}

<t:formvalid formid="formobj" layout="div" dialog="true" beforeSubmit="upload">
    <fieldset class="step">
    <div class="form"><t:upload name="fiels" buttonText="选择要导入的文件" uploader="${controller_name}.do?${empty method_name?'importExcel':method_name }" extend="*.xls;*.xlsx" id="file_upload" formData="documentTitle"></t:upload></div>
    <div class="form" id="filediv" style="height: 50px"></div>
    </fieldset>
</t:formvalid>

Import and analytical background jump method
