chrome.extension. untrequest 听者达到原始内容
原标题:chrome.extension.onRequest listener reach original content

I m using JSONP in a google chrome extension. In order to make it work, i had to add

chrome.extension.onRequest.addListener(onRequest);

然后提出这样的请求:

var jsonpURL;
$(document).ready(function(){
   /* i make the "someurl" here from a div s content */
   jsonpURL="someurl";
   chrome.extension.sendRequest({action: getJSON ,url:jsonpURL});
});

在收听器里我喜欢在页面上隐藏一些 div 。

function onRequest(request, sender, callback) {
    if (request.action ==  getJSON ) {
        $.getJSON(request.url, function(data){
                // HIDE SOME DIV
        });
    }    
}

问题:

how can i reach the original page s content in the onRequest function? or if i cant at all, how can i hide some divs depending on the result of request? i tried jquery selectors and figured out that i reach the bg.htlm, and not the original page.

最佳回答

您需要添加 < a href= > http://code.google.com/ chrome/ extensions/ content_ scripts. html" rel=“ nofolt” >content 脚本 到您想要在 JSONP 请求返回后修改的页面。 此脚本可以修改被注入的页面的 DOM 。 在内容脚本到位后, 您可以使用信件在背景页面和内容脚本之间进行沟通 。 所以基本上, 您需要做的是 < a href=" http://code.google.com/chrome/ extensions/ messsage. html" rel=“ nofol=nofoltreduled! 只要背景事件听众 < code> uncord < uncord 被启动, 您可以修改 DOM 。

更简单的选择(但更有限)是使用 programmatic 注射 在某些页面上使用javascript 。
