javascript - 在 cfm 中将文本框值从父页面传递到子窗口

Question

我正在将文本字段值从父 cfm 页面传递到我在单击按钮或链接后打开的子窗口。

<form name="parentForm" action="">
    <input type="text" id="parentValue" value="" /> 
    <input type="button" value="Open Popup"  onclick ="javascript:LaunchPopup('openP.cfm');"/> 
</form>
<script type="text/javascript"> 
    function LaunchPopup(page) {
         OpenWin = window.open(page, "myWindow", "width=400,height=200"); 
    }
</script>


<!--- Child page : openp.cfm --->
<script>
    if (opener.document){
        mother = opener.document;
        document.form1.popupValue.value = mother.parentForm.parentValue.value;
    }
</script>
<form id="form1">
    Value from the calling page: <input type="text" id="popupValue" value="" />
</form>

但出于某种原因，我无法传递我在父页面中输入的值。单击按钮后，我想查看我在父页面中输入的值。

Answer 1

父页面

<input 
    type="button" value="Open Popup"  
    onclick ="javascript:LaunchPopup('openP.cfm?parent=' + document.parentForm.parentValue.value);"
/> 

openp.cfm

<cfparam name="url.parent" default="">
<form id="form1">
    Value from the calling page: 
    <input type="text" id="popupValue" value="<cfoutput>#url.parent#</cfoutput>" />
</form>
