javascript - 将弹出窗口中的选定值传递给父窗口输入框

Question

我正在使用PHP和MySQL构建订单。

PHP表单有一个输入框，用户可在其中键入产品代码。如果用户不知道产品代码，我希望他们点击输入框旁边的图像或按钮，这会打开一个包含所有产品代码列表的弹出窗口。然后，他们可以点击他们想要的产品，并将产品代码从弹出窗口传递到该表格行的输入框。

我有下面的代码和它创建的页面图像，这样你就可以了解我想要实现的目标。

再次感谢您的帮助。 问候， 莱恩

Answer 1

如果你想要一个弹出窗口而不是<div />，我会建议采用以下方法。

在您的父页面中，您调用一个小帮助方法来显示弹出窗口：

<input type="button" name="choice" onClick="selectValue('sku1')" value="?">

添加以下JS方法：

function selectValue(id)
{
    // open popup window and pass field id
    window.open('sku.php?id=' + encodeURIComponent(id),'popuppage',
      'width=400,toolbar=1,resizable=1,scrollbars=yes,height=400,top=100,left=100');
}

function updateValue(id, value)
{
    // this gets called from the popup window and updates the field with a new value
    document.getElementById(id).value = value;
}

您的sku.php通过$_GET['id']接收所选字段并使用它来构建父回调函数：

?>
<script type="text/javascript">
function sendValue(value)
{
    var parentId = <?php echo json_encode($_GET['id']); ?>;
    window.opener.updateValue(parentId, value);
    window.close();
}
</script>

对于弹出窗口中的每一行，请将代码更改为：

<td><input type=button value="Select" onClick="sendValue('<?php echo $rows['packcode']; ?>')" /></td>

按照这种方法，弹出窗口不需要知道如何更新父表单中的字段。

Answer 2

（父窗口）

<html> 
<script language="javascript"> 
function openWindow() { 
  window.open("target.html","_blank","height=200,width=400, status=yes,toolbar=no,menubar=no,location=no"); 
} 
</script> 
<body> 
<form name=frm> 
<input id=text1 type=text> 
<input type=button onclick="javascript:openWindow()" value="Open window.."> 
</form> 
</body> 
</html>

（子窗口）

<html> 
<script language="javascript"> 
function changeParent() { 
  window.opener.document.getElementById('text1').value="Value changed..";
  window.close();
} 
</script> 
<body> 
<form> 
<input type=button onclick="javascript:changeParent()" value="Change opener's textbox's value.."> 
</form> 
</body> 
</html>

Answer 3

我的方法：使用div而不是弹出窗口。

在这里查看jsfiddle：http://jsfiddle.net/6RE7w/2/

或者将以下代码保存为 test.html 并在本地尝试。

<html>

<head>
    <script type="text/javascript" src="http://code.jquery.com/jquery.min.js"></script>
    <script type="text/javascript">
        $(window).load(function(){
            $('.btnChoice').on('click', function(){
                $('#divChoices').show()
                thefield = $(this).prev()
                $('.btnselect').on('click', function(){
                    theselected = $(this).prev()
                    thefield.val( theselected.val() )
                    $('#divChoices').hide()
                })
            })

            $('#divChoices').css({
                'border':'2px solid red',
                'position':'fixed',
                'top':'100',
                'left':'200',
                'display':'none'
            })
        });
    </script>
</head>

<body>

<div class="divform">
    <input type="checkbox" name="kvi1" id="kvi1" value="1">
    <label>Field 1: </label>
    <input size="10" type="number" id="sku1" name="sku1">
    <button id="choice1" class="btnChoice">?</button>
    <br>
    <input type="checkbox" name="kvi2" id="kvi2" value="2">
    <label>Field 2: </label>
    <input size="10"  type="number" id="sku2" name="sku2">
    <button id="choice2" class="btnChoice">?</button>
</div>

<div id="divChoices">
    Select something: 
    <br>
    <input size="10" type="number" id="ch1" name="ch1" value="11">
    <button id="btnsel1" class="btnselect">Select</button>
    <label for="ch1">bla bla bla</label>
    <br>
    <input size="10" type="number" id="ch2" name="ch2" value="22">
    <button id="btnsel2" class="btnselect">Select</button>
    <label for="ch2">ble ble ble</label>
</div>

</body>

</html>

简洁明了。

Answer 4

从您的代码中

<input type=button value="Select" onClick="sendValue(this.form.details);"

我不确定您的this.form.details是否有效。

如果它有效，请查看window.opener.document.getElementById('details').value = selvalue;

我找不到输入的ID包含details我只发现id=sku1（建议你添加" id="sku1"。

从你的身份证明它是硬编码。让我们看看当一个孩子有回调来更新父母的一些文本框时如何处理动态 Take a look at here.

第一页。

<html>
<head>
<script>
    function callFromDialog(id,data){ //for callback from the dialog
        document.getElementById(id).value = data;
        // do some thing other if you want
    }

    function choose(id){
        var URL = "secondPage.html?id=" + id + "&dummy=avoid#";
        window.open(URL,"mywindow","menubar=1,resizable=1,width=350,height=250")
    }
</script>
</head>
<body>
<input id="tbFirst" type="text" /> <button onclick="choose('tbFirst')">choose</button>
<input id="tbSecond" type="text" /> <button onclick="choose('tbSecond')">choose</button>
</body>
</html>

查看function choose我向弹出窗口发送了一个文本框ID（不要忘记在最后一个URL参数中添加虚拟数据，如&dummy=avoid#）

弹出页面

<html>
<head>
<script>
    function goSelect(data){
        var idFromCallPage = getUrlVars()["id"];
        window.opener.callFromDialog(idFromCallPage,data); //or use //window.opener.document.getElementById(idFromCallPage).value = data;
        window.close();
    }


    function getUrlVars(){
        var vars = [], hash;
        var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
        for(var i = 0; i < hashes.length; i++)
        {
            hash = hashes[i].split('=');
            vars.push(hash[0]);
            vars[hash[0]] = hash[1];
        }
        return vars;
    }
</script>
</head>
<body>
<a href="#" onclick="goSelect('Car')">Car</a> <br />
<a href="#" onclick="goSelect('Food')">Food</a> <br />
</body>
</html>

我已为父项已传递给子级的get URL param添加函数getUrlVars。

好的，当在弹出窗口中选择数据时，对于这种情况，它会调用function goSelect

在该函数中将获得发回的URL参数。

当您需要发送回父母时，只需使用 window.opener 和功能的名称，例如 window.opener.callFromDialog

完全是window.opener.callFromDialog(idFromCallPage,data);

或者如果您想使用window.opener.document.getElementById(idFromCallPage).value = data;也可以。

Answer 5

使用： opener.document.<id of document>.innerHTML = xmlhttp.responseText;
