我正在开发一个简单的书签应用程序来学习Google App Engine。此时,我将网址复制并粘贴到http://ting-1.appspot.com/submit,其中包含一个包含网址字段的表单。由于这很麻烦,我想添加镀铬扩展。我刚刚更改了hello world example,现在我使用此代码(as explained here)获取标签的网址:
<script>
window.addEventListener("load", windowLoaded, false);
function windowLoaded() {
chrome.tabs.getSelected(null, function(tab) {
document.getElementById('currentLink').innerHTML = tab.url;
tabUrl = tab.url;
});
}
document.write(tabUrl)
</script>
如何将tabUrl
传递给http://ting-1.appspot.com/submit?
谢谢!
更新
background.html
我改编自Mohamed Mansour's answer:
<script>
//React when a browser action's icon is clicked.
chrome.browserAction.onClicked.addListener(function(tab) {
//this gets the url and the title
chrome.tabs.getSelected(null, function(tab) {
tabUrl = tab.url
tabTitle = tab.title
//this posts the data to the bookmarking app
var formData = new FormData();
formData.append("url", tabUrl);
formData.append("title", tabTitle);
formData.append("pitch", "this is a note");
formData.append("user_tag_list", "tag1, tag2");
var xhr = new XMLHttpRequest();
xhr.open("POST", "http://ting-1.appspot.com/submithandlertest");
xhr.send(formData);
});
});
</script>

您使用普通的XHR(XMLHttpRequest)请求。我会把它放在你的background page中。按照此处的示例https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/Using_XMLHttpRequest。我相信你也想提交数据,所以不要忘记。我想你也想要一个POST请求。从MDC上的示例中,您可以通过以下方式联系它:
var formData = new FormData();
formData.append("username", "Groucho");
formData.append("accountnum", 123456);
var xhr = new XMLHttpRequest();
xhr.open("POST", "http://ting-1.appspot.com/submit");
xhr.send(formData);
确保您拥有manifest中的网址,以获取执行该请求的权限。
"permissions": [
"tabs",
" http://ting-1.appspot.com/submit"
],
