我认为我掌握了它,但它只是不起作用......我无法弄清楚原因。
清单:
{
"name": "Dummy Extension",
"description": "Dummy Extension Description",
"version": "2.0",
"permissions": [
"activeTab"
],
"background": {
"scripts": ["background.js"],
"persistent": false
},
"browser_action": {
"default_title": "Dummy Extension",
"default_popup": "popup.html"
},
"manifest_version": 2,
"content_scripts": [ {
"js": [ "jquery.min.js", "background.js" ],
"matches": [ "http://*/*", "https://*/*"]
}]
}
背景:
chrome.extension.onMessage.addListener( function(request,sender,sendResponse)
{
if( request.greeting === "GetURL" )
{
var tabURL = "Not set yet";
chrome.tabs.query({active:true},function(tabs){
if(tabs.length === 0) {
sendResponse({});
return;
}
tabURL = tabs[0].url;
sendResponse( {navURL:tabURL} );
});
}
}
Popup.html
<!DOCTYPE html>
<head>
<script src='popup.js'></script>
<script src='jquery.min.js'></script>
</head>
<body>
Hello World!
<br />
<input id="tabURL" type="text" />
<br />
<input value="SEND!" type="button" id="send" />
</body>
</html>
和popup.js
function getURL() {
chrome.extension.sendMessage({greeting: "GetURL"},
function (response) {
tabURL = response.navURL;
$("#tabURL").val(tabURL);
});
}
$("#send").click(getURL());
我只能弄清楚什么是错的,定义了jquery,我没有得到控制台错误。 任何帮助都会很棒!
答案 0 :(得分:2)
$("#send").click(getURL());
被执行。此外,您需要将引用传递给getURL
,而不是执行它。
修复:
$(document).ready(function(){
$("#send").click(getURL);
});
顺便说一下,您可能会在错误的控制台中查找错误。有关弹出窗口,请参阅this debugging tutorial。
