【问题描述】：

我有一个带有复选框列的报告查询，在这里，当我们检查了一些值并总结时，它将在下一页移动，在第二页有一个返回选项，当我单击返回按钮时，它必须检查先前已检查并显示为已检查的值。

如何在 apex 中处理这个问题

我的报告查询：

SELECT DISTINCT APEX_ITEM.checkbox (1, ASSOCIATED_PARTY_ID) Select_Checkbox,
                FIRST_NAME || LAST_NAME AS Associated_Party,
                EMAIL AS Associated_Party_Email,
                associated_party_id,
                EMPLOYMENT_STATUS,
                LOCATION AS Current_Location,
                CITY || STATE_PROVISION AS City_State_Provision,
                MANAGER
  FROM ASSOCIATED_PARTIES
 WHERE associated_party_id IN (SELECT associated_party_id
                                 FROM matters_associated_parties
                                WHERE matter_id = :P10_MATTER_ID);

【问题讨论】：

如果复选框已提交（如您所说），那么当您返回该页面时，它应该保持选中，所以......您不必做任何事情.

【解决方案1】：

您可以在前进时将选中的复选框 (ASSOCIATED_PARTY_ID) 保存在 Apex_collection 中。

如果用户返回，您可以从集合中加载所选的。

【解决方案2】：

如果您转到另一个页面并返回旧页面，则选择将在那里。 p_checked_values =>:p604_blc_id 它是一个顶点项目，它将存储accociated_party_id

【解决方案3】：

        <pre>
        apex_item.checkbox2(p_idx => 1,
        p_value => blc.blc_id,
        p_attributes => 'class="blc_id" id="f01_'|| rownum|| '"',
        p_checked_values =>:p604_blc_id,
        p_checked_values_delimiter => ',')"Select All",


        <input type="checkbox" onclick="$f_CheckFirstColumn(this)" id="check_all"/>

        var
        //Checkbox that was changed
        $checkBox = $(this.triggeringElement),
        //DOM object for APEX Item that holds list.
        apexItemIDList = apex.item(this.affectedElements.get(0)),
        //Convert comma list into an array or blank array
        //Note: Not sure about the "?" syntax see: http://www.talkapex.com/2009/07/javascript-if-else.html
        ids = apexItemIDList.getValue().length === 0 ? [] : apexItemIDList.getValue().split(','),
        //Index of current ID. If it's not in array, value will be -1
        idIndex = ids.indexOf($checkBox.val())
        ;

        //If box is checked and it doesn't already exist in list
        if ($checkBox.is(':checked') && idIndex < 0) {
        ids.push($checkBox.val());
        }
        //If box is unchecked and it exists in list
        else if (!$checkBox.is(':checked') && idIndex >= 0){
        ids.splice(idIndex, 1);
        }

        //Convert array back to comma delimited list
        apexItemIDList.setValue(ids.join(','));

        </pre>
