我在基于php的CMS系统的范围内工作，该系统定义了在制作新页面时可以使用的自定义表单字段。
我的数据库中有两个表，一个名为people，有三个字段，firstname，middlename和lastname，第二个表名为orders，它们还有firstname，middlename和lastname字段，以及产品，数量和成本。
我正在使用其中一个自定义字段inputSmartSearch，其工作方式有点像google建议。当我输入字母时，执行SQl查询返回匹配的结果，连接在一起。
例如，如果我将'ba'作为输入，一个结果可能是'banner，david，bruce'，在我选择它'banner，david，bruce'之后现在是inputSmartSearch字段中的文本内容。
人员表中的，david位于firstname字段中，bruce位于middlename字段中，banner位于lastname字段中。
我想要做的是找出如何访问输入智能搜索字段中存在的文本（即用户选择的任何内容），并再次将其分解为3个部分，这样我就可以将第一个名称插入到订单中。 firstname，middlename into orders.middlename和lastname into orders.lastname，以及从网站上其他更简单的字段输入到orders表中的相关字段。
可能有一个更简单的解决方案，例如使用唯一的主要猜测并将其插入到订单表中，但即便如此，我当前的问题仍然是相同的。
如何在inputmartsearch字段填满后访问该内容？
搜索生成的HTML如下：
<div id="searchBox-chooseguests" class="smartSearchBox" style="top: 199px; left: 42px; width: 190px;">
<div id="SBHeader-chooseguests" class="SBHeader">
<button tabindex="4000" class="graphicButtons buttonX" id="SBCloseButton-chooseguests" type="button">
<span>close</span>
</button></div>
<div id="SBResults-chooseguests" class="SBResults">
<a tabindex="4000" id="SB-:08490ea8-d654-1c91-cb82-00d44a4b093b" class="SBSearchItems SBSI-chooseguests " href="#">
<span class="SBMain">Sherlock Homes</span>
<span class="SBExtra">333333334</span>
</a>
</div>
<div id="SBFooter">
</div>
</div>
由于生成的HTML是动态的，我不知道它会有多大用处。
生成的实际字段的HTML永远不会更改，即使填充了值...所以我不知道如何访问它所拥有的内容。
如下：
<p class="big"><label for="ds-chooseguests">Choose Guest</label>
<br>
<input type="hidden" value=":08490ea8-d654-1c91-cb82-00d44a4b093b" id="chooseguests" name="chooseguests">
<input type="hidden" value="1" id="sff-chooseguests">
<input type="hidden" value="17" id="sdbid-chooseguests">
<input type="text" value="" class="inputSmartSearch important" title="Use % for wildcard searches." id="ds-chooseguests" name="ds-chooseguests" autocomplete="off"></p>
我受限于我可以使用的javascript（我认为），并且必须使用CMS系统定义的字段（我认为......但不确定......也许没有要求这样做......）< / p>
这里总体方向的一些指示将是惊人的。
编辑：
这是发送的_POST数据：
数组（[chooseguests] =＆gt;：08490ea8-d654-1c91-cb82-00d44a4b093b [ds-chooseguests] =＆gt; Holmes，Sherlock [chooseproducts] =＆gt; 75c72a6a-83d9-11df-951a-fa9c1ec271f2 [ds-选择产品] =＆gt;电晕[数量] =＆gt; 2 [类型] =＆gt;现金[receiptno] =＆gt; 7 [createdby] =＆gt; [creationdate] =＆gt; [command] =＆gt;保存[modifiedby] = ＆gt; [cancelclick] =＆gt; 0 [modifieddate] =＆gt; [uuid] =＆gt;：4402add3-b884-43e6-04ad-c76d92ee465b [id] =＆gt;）

我尽可能地修剪它，并且只留下那些我认为可能对问题/问题有用的评论。
答案 0 :(得分：0)
因此，如果没有看到所有正常工作的代码并知道你有什么限制，我会用这样的方法来处理它。看起来您只需从输入文本字段中读取值即可获取选择内容。
var selection = document.getElementById("ds-chooseguests").value
我想这会有选择的内容。
然后你可以对值进行拆分：
var selection_parts = selection.split(',');
现在您可以使用索引访问每个部分
selectionParts[0] = "banner ";
selectionParts[1] = "david ";
selectionParts[2] = "bruce ";
我尝试使用没有外部库的基本javascript来保持它。希望这是你的想法。
