Question

我试图了解其他开发人员在尝试使用javascript和coldfusion将变量从一个iframe传递到另一个iframe时正在做什么。

发生了什么：而不是在底部框架中显示图像是强制下载的。并且if语句的第一部分显示为好像CurrentImage是=＆＃34;＆＃34;。

会发生什么：在网址中找到的CurrentImage的值应传递到底部的iFrame，该变量将是一个图像名称，它会在底部窗口中显示该图像。

HTML主页

<FRAMESET ROWS="120,407*" FRAMEBORDER="YES" BORDER="1" FRAMESPACING="1" COLS="*"> 
    <FRAME NAME="selectFrame" SCROLLING="NO" SRC="selectframe.cfm">
    <FRAME ONFOCUS="selectFrame.reassignFocus();" NAME="imageFrame" SRC="imageframe.cfm">
</FRAMESET>

在selectframe.cfm中找到：

<HTML>
        <HEAD>
            <TITLE>Link Fax Image</TITLE>

            <SCRIPT LANGUAGE="JavaScript">
            <!--
            <CFIF SubAction IS "ImageLinked" OR SubAction IS "" OR SubAction IS "ErrNoImages" OR SubAction IS "ErrImageDeleted" OR SubAction IS "NoOverwrite">
            parent.imageFrame.location.href="imageframe.cfm?CurrentImage=<CFOUTPUT>#CurrentImage#</CFOUTPUT>";

            </CFIF>
//-->
            </SCRIPT>

imageframe.cfm代码：

 <CFPARAM NAME="CurrentImage" DEFAULT=""> 

<!--- If CurrentImage is blank, display the following message --->
<CFIF #CurrentImage# IS "">
<HTML>
    <HEAD>
        <TITLE>No images to link at this time.</TITLE>
    </HEAD>
    <BODY>
    <CENTER><H2>No images to link at this time.</H2></CENTER>
    <CENTER><A HREF="/admin/imagelink/" TARGET="_parent">Refresh Page</A></CENTER>
</HTML>

<CFELSE>
<h3>Yes there is a Current Image</h3>
    <CFIF #CurrentImage# NEQ "NULL">
        <CFIF FileExists("#FaxImageTempDir##CurrentImage#")>
            <CFIF CurrentImage CONTAINS ".PDF">
                <CFCONTENT TYPE="application/pdf" FILE="#FaxImageTempDir##CurrentImage#" DELETEFILE="No">
            <CFELSE>
                <CFCONTENT TYPE="image/tiff" FILE="#FaxImageTempDir##CurrentImage#" DELETEFILE="No">
            </CFIF>
        <CFELSE>
        File not found, please contact support.
        </CFIF>
    </CFIF>
</CFIF>

我遇到了同样的问题，却忘了这么简单。

在CFOUTPUT中包装框架集

因此，如果您转到页面：page.cfm？var = ABC123

      <cfoutput>

      <FRAMESET ROWS="120,407*" FRAMEBORDER="YES" BORDER="1" FRAMESPACING="1" COLS="*"> 
      <FRAME NAME="selectFrame" SCROLLING="NO" SRC="selectframe.cfm?var=#var#">
      <FRAME ONFOCUS="selectFrame.reassignFocus();" NAME="imageFrame" SRC="imageframe.cfm">
      </FRAMESET>

      </cfoutput>

ABC123将传递到框架集中。

下面是通过RaspberryPi设置电视留言板的示例。我可以使用相同的代码创建多个留言板。

      <HTML>

      <cfoutput>

      <frameset rows="0%,15%,69%,16%" framespacing="0">

      <frame src="force.cfm?said=#said#" name="force" frameborder="0" hspace="0" vspace="0" marginheight="0" scrolling="no">

      <frame src="pit.cfm?said=#said#" name="pit" frameborder="0" hspace="0" vspace="0" marginheight="0" scrolling="no">

      <frameset cols="65%,35%" hspace="0" vspace="0" marginheight="0" framespacing="0">

      <FRAME src="_schedule.cfm?said=#said#" name="sch" hspace="0" vspace="0" marginheight="0" frameborder="0" scrolling="no">
      <FRAME src="_advert.cfm?said=#said#" name="banner" hspace="0" vspace="0" marginheight="0" frameborder="0" scrolling="no">

      </frameset>

      <frame src="pib.cfm?said=#said#" hspace="0" vspace="0" marginheight="0" frameborder="0" scrolling="no" name="bot">

      </frameset>
      </cfoutput>
      </HTML>
