javascript - 将 XMLHttpRequest 转换为 JSONP

Question

帮助，我需要更改此代码以支持远程域访问:

document.write(url);
    var http = getHTTPObject();
      http.open("GET", url, true);
      http.onreadystatechange = function() {
          if (http.readyState == 4) {
              parseData(http.responseText);
          }
      }
      http.send(null);  

Answer 1

在你的 js 中:

function goRemote(url) {
  var script = document.createElement("script");
  script.src=url;
  document.body.appendChild(script);
}
function parseDate(json) {
  // do your fun here.
}

在你返回的 js 中:

parseData({"foo": "bar"});
