我尝试从另一个 js 文件调用函数，该文件与我的主 js 脚本和 html 文件位于同一应用程序目录中。我收到一条错误，声称引用的函数不存在。我已经按照正确的顺序引用了主 html 文件中的两个脚本，但我无法弄清楚为什么它无法检测到该函数。我只能假设它与 dojo 如何解析文件有关，并且已经尝试了它的 dojo/domReady!和 dojo/ready 模块希望强制加载脚本。我觉得这应该比我想象的要简单得多。任何帮助将不胜感激。

ready(function() {
console.log("request start");
function sendRequest (url,assetCode,fromDate,toDate) {

console.log(JSON.stringify(resp));
var naStorageJSON = resp;

console.log("request end");
});
});
main-js.js
require([

ready(function() {
console.log("Main Start");
var url = "http://*********";
var assetCode = ["**"];
var toDate = "****";
var fromDate ="*****";
on(dom.byId("senecaLakeBtn"),"click", sendRequest(url,assetCode,toDate,fromDate));
console.log("Main End");
});
});
最佳答案
问题的范围在这里。通过在 js 脚本顶部声明一个空数组(在其连续函数之外)，应用程序中的其他脚本可以访问该函数。
var app = [];
require(["dojo/dom","dojo/on","dojo/request","dojo/json","dojo/parser","dojo/ready"
], function(dom,on,request,JSON,parser,ready) {
ready(function(){
app.sendRequest = function sendRequest (url,assetCode,fromDate,toDate) {
...
...
}
}
可以通过引用从其他脚本调用它们
app.sendRequest(arg1,arg2,arg3);
