在Chrome 19.0.1084.1中进行测试，这对我很有帮助....
popup.html
<！doctype html>

< script src =popup.js>< / script>
< / head>

< div id =header>
< p id =intro> ; / p>
< / div><！ - END header - > $ p
< / div>按钮>按钮> ;
< div id =content>
< / div><！ - END content - >
< / div>
< / body>

popup.js
$（document） .ready（function（）{
$（＃button）。click（function（）{
$（＃intro）。text（Hello，im added）;
alert（点击）;
}）;
}）;
可能的错误
我认为可能是什么你的问题是你的清单中有manifest_version：2，并且你的popup.html看起来像这样....
<！doctype html>
< html>
< head>
< script src =jquery-1.7.1.min.js>< / script>
<！ - script src =popup.js>< / script - >
< script>
$（document）.ready（function（）{
$（＃button）。click（function（）{
$（＃intro）。text（Hello， im添加）;
alert（Clicked）;
}）;
}）;
< / script>
< / head>
< body>
< div id =extension_container>
< div id =header>
< p id =intro>结果在这里< / p>
< button type =buttonid =button> Click Me！< / button>
< / div> <！ - END标题 - >
< div id =content>
< / div> <！ - END内容 - >
< / div>
< / body>
< / html>
...这不起作用，因为内联脚本不允许在清单版本2中使用。
Im new on Google Chrome Extensions coding, and i have some basic questions.
I want to make a Chrome Extension, and the scheme is the following:
-a popup window, containing buttons and result fields (popup.html)
-when a button is clicked, i want to trigger an event, this event should connect to a webserver (i make the servlet too), and gather information from the server. (XMLHttpRequest())
-after that, i want my extension to load the gathered information into one of the result fields.
Simple, isn't it? But i have several problems, right at the beginning:( I started developing with reading tutorials, but i have fog on the main structure of an extension. Now, i started an app, containing a popup.html, manifest.json ... In popup.html theres a result field, and a button
<div id="extension_container">
<div id="header">
<p id="intro">Result here</p>
<button type="button" id="button">Click Me!</button>
</div> <!-- END header -->
<div id="content">
</div> <!-- END content -->
When button is clicked, i trigger an event, handeled with jquery, code here:
<script>
$(document).ready(function(){
$("#button").click(function(){
$("#intro").text("Hello, im added");
alert("Clicked");
});
});
</script>
And here comes the problem, in popup.html this doesnt work, if i load it to Chrome, nothing happens. Otherwise, if i open popup.html in browser, not as an extension, everything works fine. So, i think i have basic misunderstandings on extension structures, starting with background pages, background javascript and so on.. :( Could anyone help me?
Testing in Chrome 19.0.1084.1 this worked for me....
popup.html
<!doctype html>
<html>
<head>
<script src="jquery-1.7.1.min.js"></script>
<script src="popup.js"></script>
</head>
<body>
<div id="extension_container">
<div id="header">
<p id="intro">Result here</p>
<button type="button" id="button">Click Me!</button>
</div> <!-- END header -->
<div id="content">
</div> <!-- END content -->
</div>
</body>
</html>
popup.js
$(document).ready(function() {
$("#button").click(function() {
$("#intro").text("Hello, im added");
alert("Clicked");
});
});
Possible Error
I think what MIGHT be your problem is that you have "manifest_version" : 2 in your manifest and your popup.html looks something like this....
<!doctype html>
<html>
<head>
<script src="jquery-1.7.1.min.js"></script>
<!--script src="popup.js"></script-->
<script>
$(document).ready(function() {
$("#button").click(function() {
$("#intro").text("Hello, im added");
alert("Clicked");
});
});
</script>
</head>
<body>
<div id="extension_container">
<div id="header">
<p id="intro">Result here</p>
<button type="button" id="button">Click Me!</button>
</div> <!-- END header -->
<div id="content">
</div> <!-- END content -->
</div>
</body>
</html>
...this wouldnt work because inline scripts arent allowed in manifest version 2.
