Question

我正在尝试使用Knockout JS创建一个主细节页面，如下图所示 enter image description here

我有一个问题是从详细信息中获取bootstrap模态的值。例如，在辅助客户端列单击“浏览”按钮后，将在引导模式中显示辅助客户端列表。 enter image description here

单击选择链接后，我无法将值（SubsidiaryClientID，SubsidiaryClientNo和Name）返回到父页面。如何获取这些值并设置为父页面？

以下是代码：

抱歉Willy，我已经在asp .net上工作了，所以我只提供了一个敲门和html的示例代码。希望这可以帮助你

<强> HTML

// Parent Page Code
<!-- ko foreach: ClientList -->
<!-- ko if: isActive -->
<div class="col-xs-12">
    <div class="col-xs-4" data-bind="text: SubsidiaryClientID"></div>
    <div class="col-xs-4" data-bind="text: SubsidiaryClientNo"></div>
    <div class="col-xs-4" data-bind="text: SubsidiaryClientName"></div>
</div>
<!-- ko -->

您可以在每一行定义自己的属性，并将该ro分配给js函数。

像这样：

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:cs1="https://defaultnamespace/abc" xmlns:cs2="https://defaultnamespace1/abc" exclude-result-prefixes="cs1 cs2">
  <xsl:template match="/">
      <xsl:apply-templates/>
  </xsl:template>

  <xsl:template match="cs1:Report">
    <xsl:for-each select="cs1:Conversion/cs1:Type">
      <xsl:element name="Converting">
        <xsl:value-of select="."/>
      </xsl:element>
    </xsl:for-each>
    <xsl:element name="LastOne">
