问题描述
我正在尝试构建一个使用xhr请求从外部api获取响应的chrome扩展。我已经在扩展文件中设置了扩展的权限,但xhr请求正在网络中被取消。
I am trying to build a chrome extension which uses a xhr request to get response from a external api. I have set the permission for the extension as mention in the chrome extension document still xhr request is getting cancelled in network.
manifest.json
manifest.json
"browser_action": {
"default_icon": "icon.png",
"default_popup": "popup.html",
"default_title": "Chrome extension title"
},
"permissions": [
"activeTab",
"storage",
"https://*/"
]
In popup.js
var xhr = new XMLHttpRequest();
xhr.open("GET", "https://putsreq.com/4z01VNOBPeD144njWNdi", true);
xhr.onreadystatechange = function() {
if (xhr.readyState == 4 && this.status == 200) {
var theValue = "asdfassf";
alert("This is doen");
// chrome.storage.sync.set({'value': theValue}, ()=> {
// // Notify that we saved.
// document.location.href = "timer.html";
// });
}
}
xhr.send();
推荐答案
我错过了添加event.preventDefault()用于取消默认表单提交。当我将event.preventDefault()代码添加到上面的代码中时它就起作用了。
I missed to add event.preventDefault(), that used to cancel the default form submit. When i added event.preventDefault() code to the above code it worked.
