Question

我试图从另一个js文件中调用一个函数，该文件位于与我的主js脚本和html文件相同的应用程序目录中。我收到一个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，但是我不知道为什么它无法检测到这个函数。我只能假设它与dojo如何解析文件并尝试了dojo / domReady有关！和dojo / ready模块希望强制加载脚本。我觉得这应该比我做到的要简单得多。任何帮助将不胜感激。

html

请求-js.js

require(["dojo/dom","dojo/on","dojo/request","dojo/json","dojo/parser","dojo/ready"


], function(dom,on,request,JSON,parser,ready) {

ready(function() {
    console.log("request start");

    function sendRequest (url,assetCode,fromDate,toDate) {
        console.log("Request innit");
        request(url,{
            method: "POST",
            handleAs: "json",
            headers: {"Content-Type": "application/json"},
            data: JSON.stringify(
                [
                    {
                        "AssetCodes": assetCode,
                        "FromGasDay": fromDate,
                        "ToGasDate": toDate

                    }

                ]
            )


        }).then(function(resp){
            console.log(JSON.stringify(resp));
            var naStorageJSON = resp;
        });
    }

    console.log("request end");

});

});

主js.js

require([
"dojo/dom","dojo/on","dojo/parser","dojo/json","dojo/request","dojo/ready"

], function(dom,on,parser,JSON,request,ready) {


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");


});
});

问题在于范围。通过在js脚本的顶部声明一个空数组（在其连续函数之外），该函数可以被应用程序中的其他脚本访问。

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);

从其他JS文件访问函数 - DOJO
