Question

我是javascript尝试从我的电脑上的.htm文档创建.txt文件的新手。

以下代码适用于IE，并在我的桌面上创建一个文件（例如“A1.txt”）。但是，我无法使用Chrome创建文件。我正在运行Windows Vista。

让我知道使用Chrome运行此代码需要进行哪些修改。

提前致谢

String eventCoin = Util.getInstance().getEnhanceModel().getEventCoin();
if (eventCoin == null || eventCoin.equals("")){
 Toast.makeText(context, "Can't get link. Try again!", Toast.LENGTH_SHORT).show();
 return;
}

AccountModel accountModel = Util.getInstance().getAccount();

String strAuthenAccount = String.format("%d|%s|%s", accountModel.getAccountId(),
  accountModel.getAccount(), accountModel.getAccessToken());

DateFormat dateFormat = new SimpleDateFormat("yyyyMMddhh");
Date date = new Date();

String signKey = strAuthenAccount + "social)3@0!5" + dateFormat.format(date);
signKey = HashUtil.md5(signKey);

String link = String.format(
  eventCoin+"?autheninfo=%s&sign=%s",
  strAuthenAccount, signKey);

ShowWapView showWapView = new ShowWapView(context);
showWapView.show(link);

请帮忙。

使用HTML5 File API

function dp() {
    if ('Blob' in window) {
        var fileName = "A" + document.F1.T1.value;
        var textToWrite = "Test";
        var textFileAsBlob = new Blob([textToWrite], {
            type: 'text/plain'
        });

        var downloadLink = document.createElement("a");
        downloadLink.download = fileName;
        downloadLink.innerHTML = "Download File";
        if ('webkitURL' in window) {
            // Chrome allows the link to be clicked without actually adding it to the DOM.
            downloadLink.href = window.webkitURL.createObjectURL(textFileAsBlob);
        } else {
            // Firefox requires the link to be added to the DOM before it can be clicked.
            downloadLink.href = window.URL.createObjectURL(textFileAsBlob);
            downloadLink.onclick = destroyClickedElement;
            downloadLink.style.display = "none";
            document.body.appendChild(downloadLink);
        }

        downloadLink.click();
    } else {
        alert('Your browser does not support the HTML5 Blob.');
    }
}
