我尝试过：

I need to add a Javascript file from the server to the LocalStorage and site header. i try this code but some things wrong??


i have external script , i want only One time download script file to speed up site load. title attribute download script file for each load page

What I have tried:

var s = document.createElement("script");
s.type = "text/javascript";
s.src = localStorage.theImage;
s.title = "myJavaScript";
$("head").append(s);

function addScript() {

    var csvRequest = new Request({
        url: "splitNumber.js",
        onSuccess: function (response) {
            var responseFile = response;
            var file = responseFile;
            var reader = new FileReader();

            reader.onload = function (e) {
                var s = document.createElement("script");
                s.type = "text/javascript";
                s.src = reader.result;
                localStorage.theImage = reader.result;
                $("head").append(s);
            }

            reader.readAsDataURL(file);//attempts to read the file in question.
        });
    }
}

推荐答案

（head）。append（s）;

函数addScript（）{

var csvRequest = new Request（{
url：splitNumber.js，
onSuccess：function（response） {
var responseFile = response;
var file = responseFile;
var reader = new FileReader（）;

reader.onload = function（e）{
var s = document.createElement（script）;
s.type =text / javascript;
s.src = reader.result;
localStorage.theImage = reader。结果;

("head").append(s); function addScript() { var csvRequest = new Request({ url: "splitNumber.js", onSuccess: function (response) { var responseFile = response; var file = responseFile; var reader = new FileReader(); reader.onload = function (e) { var s = document.createElement("script"); s.type = "text/javascript"; s.src = reader.result; localStorage.theImage = reader.result;

（head）。append（s）;
}

reader.readAsDataURL（file）; //尝试读取有问题的文件。
}）;
}
}

("head").append(s); } reader.readAsDataURL(file);//attempts to read the file in question. }); } }
