抓取代码在 php 中不起作用以形成控件 [英] Scraping code not working in php to form controls

问题描述

我正在尝试将网页内容抓取到我的表单控件中，没有函数我正在获取输出，但是当我创建函数并分配给按钮单击事件以在文本框中显示输出时，它不起作用，让我知道我在哪里搞砸了.

I am trying to scrape webpage content to my form controls, Without function i am getting output, but when i created function and assigned to button click event to display the output in textbox its not working, let me know where i am messed.

<script type="text/javascript">
function Assign()
{
$html = file_get_contents("http://geoportaal.maaamet.ee/url/xgis-ky.php?ky=79401:006:0812");
preg_match_all('(<li.*?>.*?</li>)', $html, $matches);
$one=$matches[0][0];
document.getElementById("OutputField").value = $one;
}
</script>
<input id="OutputField" type="text" style="width:200px"/>
<input type="button" value="Assign Value" onclick="Assign()"/>

推荐答案

首先，你必须分离你的 html、php、javascript 代码.我更改了您的代码，您可以尝试一下.如果您以正确的方式使用它，它将起作用.

Firstly, you must separate your html, php, javascript code. I changed your code and you can try it. If you use it in right way it will work.

<?php
$html = file_get_contents("http://geoportaal.maaamet.ee/url/xgis-ky.php?ky=79401:006:0812");
preg_match_all('(<li.*?>.*?</li>)', $html, $matches);
$one=$matches[0][0];
?>

<script type="text/javascript">
    function Assign() {
        document.getElementById("OutputField").value = "<?=$one?>";
    }
</script>

<input id="OutputField" type="text" style="width:200px"/>
<input type="button" value="Assign Value" onclick="Assign()"/>
