Question

我有以下代码，当我选中复选框时，该值不会反映在dtWebVo.cpdCourseInfo [??]。chkSelect中。因为我想在db中获取值并进行更新。我该怎么办？

NSUInteger audioDurationSeconds = (long)CMTimeGetSeconds(audioDuration);
NSUInteger minutes = floor(audioDurationSeconds % 3600 / 60);
NSUInteger seconds = floor(audioDurationSeconds % 3600 % 60);
NSString *time = [NSString stringWithFormat:@"%02ld:%02ld", minutes, seconds];

Answer 1

<p:dataTable var="cpdCourseInfoDetail" tableStyle="width:auto" 
    value="#{dtWebVo.cpdCourseInfo}"
    rowKey="#{cpdCourseInfoDetail.selfInputCourseID}"
    rowIndexVar="index" selection="#{dtWebVo.selectedCPDCourseInfo}"
    id="gridCourseInfo"  styleClass="ui-edb-td-wrap-table ui-edb-header-style table-no-select-all" >
   <p:column id="x_checkbox" selectionMode="multiple" onload="disableCheckBox(this.id,#{cpdCourseInfoDetail.cpdStatusAction})"></p:column>
