添加Hummer.loadScriptWithUrl

[chenyulun]

class {
inProgress = {};
loadScriptWithUrl(url, done,key) { // webpack里面有key参数，用于表示是否用户主动加载了js,直接监听，不需要创建添加
if (inProgress[url]) {
        inProgress[url].push(done);
        return;
      }
      let script, needAttach;
      if (key !== undefined) {
        const scripts = document.getElementsByTagName("script");
        for (let i = 0; i < scripts.length; i++) {
          const s = scripts[i];
          if (s.getAttribute("src") == url) {
            script = s;
            break;
          }
        }
      }
      if (!script) {
        needAttach = true;
        script = document.createElement("script");

        script.charset = "utf-8";
        script.timeout = 120;
        // if (__webpack_require__.nc) {
          // script.setAttribute("nonce", __webpack_require__.nc);
       //  }

        script.src = url;
      }
      inProgress[url] = [done];
      const onScriptComplete = (prev, event, error) => {
        // avoid mem leaks in IE.
        script.onerror = script.onload = null;
        clearTimeout(timeout);
        const doneFns = inProgress[url];
        delete inProgress[url];
        script.parentNode && script.parentNode.removeChild(script);
        doneFns && doneFns.forEach((fn) => fn(error));
        if (prev) return prev(event);
      };
      const timeout = setTimeout(
        onScriptComplete.bind(null, undefined, {
          type: "timeout",
          target: script,
        }),
        120000
      );
      script.onerror = onScriptComplete.bind(null, script.onerror, {'errCode': '404', 'errMsg': 'Not Found'});
      script.onload = onScriptComplete.bind(null, script.onload, null);
      needAttach && document.head.appendChild(script);
    };
}
}

代码都是webpack里面的，帮忙添加一下发布，谢谢了
