javascript - 将选定的值从弹出窗口传递到父窗口输入框

javascript - pass selected value from popup window to parent window input box

提问by Smudger

I am building an order form with PHP and MySQL.

我正在用 PHP 和 MySQL 构建一个订单。

The PHP Form has an input box where the user types in a product code. In the event that the user does not know the product code, I want them to click on an image or button next to the input box, which opens a popup with a list of all product codes. they can then click on the product they want and the product code is passed from the popup to the input box on that table row.

PHP 表单有一个输入框，用户可以在其中输入产品代码。如果用户不知道产品代码，我希望他们单击​​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，产品代码从弹出窗口传递到表格行上的输入框。

I have the code of my page below and the image of the page it creates so you can get a feel for what I am wanting to acheive.

我在下面有我的页面的代码和它创建的页面的图像，因此您可以了解我想要实现的目标。

If you want a popup window rather than a <div />, I would suggest the following approach.

如果你想要一个弹出窗口而不是一个<div />，我建议使用以下方法。

In your parent page, you call a small helper method to show the popup window:

在您的父页面中，您调用一个小的辅助方法来显示弹出窗口：

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

Add the following JS methods:

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;
}

Your sku.phpreceives the selected field via $_GET['id']and uses it to construct the parent callback function:

您sku.php通过接收所选字段$_GET['id']并使用它来构造父回调函数：

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

For each row in your popup, change code to this:

对于弹出窗口中的每一行，将代码更改为：

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

Following this approach, the popup window doesn't need to know how to update fields in the parent form.

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。

My approach: use a divinstead of a pop-up window.

我的方法：使用一个div而不是一个弹出窗口。

See it working in the jsfiddle here: http://jsfiddle.net/6RE7w/2/

在这里查看它在 jsfiddle 中的工作：http: //jsfiddle.net/6RE7w/2/

Or save the code below as test.htmland try it locally.

From your code

从你的代码

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

Im not sure that your this.form.detailsvalid or not.

我不确定您是否this.form.details有效。

IF it's valid, have a look in window.opener.document.getElementById('details').value = selvalue;

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

I can't found an input's id contain detailsI'm just found only id=sku1(recommend you to add "like id="sku1").

我找不到输入的 id 包含detailsI'm just found only id=sku1(建议您添加"like id="sku1")。

And from your id it's hardcode. Let's see how to do with dynamic when a child has callback to update some textbox on the parent Take a look at here.

从你的 id 来看，它是硬编码。让我们看看当孩子有回调来更新父母上的一些文本框时如何处理动态 看看这里。

First page.

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>

Look in function chooseI'm sent an id of textbox to the popup window (don't forget to add dummy data at last of URL param like &dummy=avoid#)

查看function choose我已将文本框的 id 发送到弹出窗口（不要忘记在 URL 参数的最后添加虚拟数据，例如&dummy=avoid#）

Popup Page

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>

I have add function getUrlVars for get URL paramthat the parent has pass to child.

我添加了函数 getUrlVars 来获取父级传递给子级的URL 参数。

Okay, when select datain the popup, for this case it's will call function goSelect

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

In that function will get URL param to sent back.

在该函数中，将获取要发回的 URL 参数。

And when you need to sent back to the parent just use window.openerand the name of functionlike window.opener.callFromDialog

当您需要发送回父级时，只需使用window.opener和函数名称，如window.opener.callFromDialog

By fully is window.opener.callFromDialog(idFromCallPage,data);

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

Or if you want to use window.opener.document.getElementById(idFromCallPage).value = data;It's ok too.

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