我正在尝试让我的Chrome扩展程序注入一些javascript content_scripts,使用此前一个答案作为参考.

的manifest.json

"name": "My Chrome Extension",
"version": "1.0",
"manifest_version": 2,
"content_scripts": [{
    "matches": ["http://pagetoinject/script/into/*"],
    "js": ["contentscript.js"]
}]  

contenscript.js:

var s = document.createElement('script');
s.src = chrome.extension.getURL("script.js");
(document.head||document.documentElement).appendChild(s);
s.parentNode.removeChild(s);

(也尝试过 这个方法没有成功.)

var s = document.createElement('script');
s.src = chrome.extension.getURL("script.js");
s.onload = function() {
    this.parentNode.removeChild(this);
};
(document.head||document.documentElement).appendChild(s);

我一直收到这个javascript错误.这是一个截图.

GET chrome-extension://invalid/ (anonymous function)

所以我基本上要完成的是mysql查询中的foreach行,它打印出来自该行数据的html.这就是我所拥有的,它不断给我一个错误的foreach.

<?php

$shots = mysql_query("SELECT * FROM shots") or die(mysql_error());

while($row=mysql_fetch_array($shots))
$data[]=$row;


foreach($shots as $data)

  if (!empty($data)){

  $id = $data["id"];
  $shotby = $data["shot"];
  $passby = $data["pass"];
  $time = $data["time"];
?>


<div class="feedbody">

    <div class="title"><?php echo $shotby; ?></div>
    <div class="feed-data">: gets a pass from <span><?php echo $passby; ?</span> and he takes a shot!</div>
    <img class="dot" src="images/dot.png" />

</div>
<?php
}

}
?>

或类似的东西.任何人都可以帮助我指出正确的方向.我一直试图找到答案.

编辑:根据要求添加错误.

Warning: Invalid argument supplied for foreach() in /home/content/93/7527593/html/fusionboard/includes/feed.php on line 7

我一直在搜索所有的SO并通过谷歌文档阅读,但我似乎无法找到解决方案.

我的Chrome扩展程序是注入内容脚本,我想设置一个onRequest.listenersendRequests到内容脚本.这是我以前用过的脚本onRequest.listener.问题是我出于某种未知原因不断收到此错误.

错误信息:

Uncaught TypeError: Cannot ready property 'onRequest' of undefined

contentscript.js line 1;

这是相关代码......

的manifest.json
