Posted 2020-06-26

一、针对My97日历控件的绑定

普通绑定和特殊格式绑定（红色部分）

<!-- ko foreach: items -->
<td class="ruyeeTableTDLable"> <span>批准专业日期</span></td>
<td class="ruyeeTableDataCell">
    <div class="input-group">
        <input data-validation-engine="validate[maxSize[10]],validate[required],custom[date],"
               data-bind="attr: { id: ‘A7615‘ +$index(),value:A7615} " type="text" class="form-control">
        <div class="input-group-addon ">
            <span class="glyphicon glyphicon-calendar"
                  data-bind="attr: { onclick: ‘WdatePicker({ el:A7615‘ + $index() + ‘})‘ }">

            </span>
        </div>
    </div>
