问题描述
我正在尝试从弹出页面获取链接值或href,并在文本框中将内容添加到父页面。我根本不知道javascript,并且不明白为什么两个链接都不起作用....可以列出2个项目或者可以有500个所以我需要这个与动态列表一起工作任何帮助都会很棒!谢谢!!!!
I am trying to get the link value or href from a popup page and add the content to the parent page in a text box. I don't knwo javascript well at all and dont understand why both links are not working.... There can be 2 items listed or there can be 500 so i need this to work with a dynamic list any help would be great! Thank you!!!!
这就是我所拥有的。
弹出页面....
<a href="#item1" id="ddlNames" name="ddlNames"><img src="link to item 1 image"> </a>
<a href="#item2" id="ddlNames" name="ddlNames"> <img src="link to item 2 image"> </a>
<input type="button" value="Select" onclick="SetName();" />
<script type="text/javascript">
function SetName() {
if (window.opener != null && !window.opener.closed) {
var txtName = window.opener.document.getElementById("txtName");
txtName.value = document.getElementById("ddlNames").href;
}
window.close();
}
</script>
以下是主页上的代码。
<script type="text/javascript">
var popup;
function SelectName() {
popup = window.open("img_sel.php", "Popup", "width=300,height=100");
popup.focus();
}
</script>
<input type="text" name="image" id="txtName" />
<input type="button" value="Select Name" onclick="SelectName()" />
这就是我现在拥有的......
<?php
$colors = array("red","green","blue","yellow");
foreach ($colors as $value)
{
echo "<a href=\"#$value\" id=\"$value\" name=\"$value\"> $value </a>";
}
?>
<input type="button" value="Select" onclick="SetName();" />
<script type="text/javascript">
cars=<?php echo json_encode($colors); ?>;
function SetName() {
if (window.opener != null && !window.opener.closed) {
var txtName = window.opener.document.getElementById("txtName");
for (var i=0;i<cars.length;i++)
{
txtName.value = document.getElementById((cars[i])).href;
}
}
window.close();
}
</script>
推荐答案
同样的ids不是个好主意,所以你可以做这样,就没有必要使用id。
这是完整的代码
Same ids are not the good idea so you can do it this way, there is no need to use id.
Here is full code
