使用 Google Closure 进行 Ajax 调用
我是 Google Closure 库的新手，我正在尝试模拟类似于 Jquery 的 $.ajax 函数的东西。这是我尝试过的以及得到的回应。
触发器来自 Chrome 扩展 右键单击
chrome.contextMenus.create({"title": "sample_closure", "onclick": samp.myProject.fun1,"contexts":['selection']});
这会触发 fun1 函数，其定义如下：
samp.myProject.fun1 = function(info,tab) {
var string_url = info.selectionText;
//String_url works fine and passed to the function below.
samp.myProject.getAjaxData(string_url);
}
getAjaxData 函数如下。
goog.require("goog.net.XhrIo");
samp.myProject.getAjaxData = function(url) {
goog.net.XhrIo.send(url, function(event) {
alert(event.target.getResponseText());
});
}
但是当我调用 getAjaxData 函数时出现此错误。
Error in event handler for 'contextMenus': TypeError: Cannot read property 'XhrIo' of undefined
谁能告诉我哪里出错了。我检查了 xhrio.send 函数需要传递的参数类型，它具有字符串类型。
I am new to Google Closure library, and I am trying to simulate something similar to that of Jquery's $.ajax function. Here is what I tried and what I got in response.
The trigger is from Chrome Extensions Right click
chrome.contextMenus.create({"title": "sample_closure", "onclick": samp.myProject.fun1,"contexts":['selection']});
This triggers the fun1 function which is defined as below:
samp.myProject.fun1 = function(info,tab) {
var string_url = info.selectionText;
//String_url works fine and passed to the function below.
samp.myProject.getAjaxData(string_url);
}
The getAjaxData function is as below.
goog.require("goog.net.XhrIo");
samp.myProject.getAjaxData = function(url) {
goog.net.XhrIo.send(url, function(event) {
alert(event.target.getResponseText());
});
}
But I get this error when I call the getAjaxData function.
Error in event handler for 'contextMenus': TypeError: Cannot read property 'XhrIo' of undefined
Can anyone tell me where I am going wrong.. I checked the Argument type that need to be passed for xhrio.send function and it has string type.

解决了这个问题。base.js 的路径导致了这个问题。
不删除这个问题，因为你们中的一些人可能会面临同样的问题并留给他们。 因此，请检查您的closure-library的base.js路径以解决此问题
Solved this issue.. The path to base.js is causing this problem.
