按下按钮后,在弹出窗口中打开新标签时出现问题。到目前为止,我的测试表明,按下按钮后我可以打开一个新选项卡,但是一旦我在exec "$JAVACMD" \
$MAVEN_OPTS \
$MAVEN_DEBUG_OPTS \
-classpath "${M2_HOME}"/boot/plexus-classworlds-*.jar \
"-Dclassworlds.conf=${M2_HOME}/bin/m2.conf" \
"-Dmaven.home=${M2_HOME}" "-Dmaven.multiModuleProjectDirectory=${MAVEN_PROJECTBASEDIR}" \
${CLASSWORLDS_LAUNCHER} "$@"
调用.then()
的{{1}}内尝试这样做,相同的代码就不再有效了。
这是相关代码部分的一个亮点(来自下面的 popup / menu.js ):
browser.tabs.query()
最终我计划获取当前活动标签的URL,这将改变打开的新标签的目的地。该计划最终用于可以在具有相同内容的镜像网站之间切换的插件,即使当前网站已关闭(由于高流量)。
的manifest.json :
// Getting the currently active tab
var gettingActiveTab = browser.tabs.query({active: true, currentWindow: true});
gettingActiveTab.then((tabs) => {
// Open desired tab. This fails for some reason?
var creating = browser.tabs.create({
url:"https://stackoverflow.com/users/641534/antonchanning"
});
creating.then(onCreated, onError);
});
//test to show we can actually open a tab successfully. This works...
var creating = browser.tabs.create({
url:"https://stackexchange.com/users/322227/antonchanning"
});
creating.then(onCreated, onError);

要下载测试用例的完整代码(包括图标),请从this GitHub repository下载ZIP,然后通过function onCreated(tab) {
console.log(`Created new tab: ${tab.id}`)
}
function onError(error) {
console.log(`Error: ${error}`);
}
document.addEventListener("click", (e) => {
if (e.target.classList.contains("opennewtab")) {
var gettingActiveTab = browser.tabs.query({active: true, currentWindow: true});
gettingActiveTab.then((tabs) => {
// Open desired tab. This fails for some reason?
var creating = browser.tabs.create({
url:"https://stackoverflow.com/users/641534/antonchanning"
});
creating.then(onCreated, onError);
});
//test to show we can actually open a tab successfully
var creating = browser.tabs.create({

});
creating.then(onCreated, onError);
}
window.close();
});
标签添加为临时插件。
答案 0 :(得分:1)
在window.close()
browser.tabs.create()
执行.then()
之前,您browser.tabs.query()
弹出窗口是不可行的。 browser.tabs.query()
是异步的。 .then()
不会立即执行。关闭弹出窗口时,上下文将被销毁,执行将停止。因此,.then()
不存在被调用。
如果您想在创建选项卡后关闭弹出窗口,则{/ 1}}需要在打开选项卡后执行。
这就像是:
window.close()
