强制下载.mp3或.zip文件的Ajax成功 [英] Force Download of .mp3 or .zip files on Ajax success

问题描述

在用户填写电子邮件验证表（通过AJAX提交）后，如果AJAX通话响应成功，我想强制下载到当前浏览器窗口中。

After a user fills out an email verification form (which is submitted via AJAX), I want to force a download to start in the current browser window if the AJAX call response is successful.

电子邮件验证表单如下：

The email verification form looks like:

<form id="form_download_email" method="POST" action="music_email_verification.php">
    <input id="download_email" type="text" tabindex="1" /> <br/>
    <a href="javascript:void(0);" id="download_email_button">
        Download!
    </a>
</form>

一旦点击download_email_button，js / jquery就像这样：

The js/jquery once the "download_email_button" is clicked looks like this:

$("#download_email_button").click(function() {

    var action = $("#form_download_email").attr('action');
    var form_data = {email: $("#download_email").val()};

    $.ajax({
        type: "POST",
        url: action,
        data: form_data,
        success: function(response){
            if(response == 'success'){    
                window.location.assign('URL to .mp3 or ZIP');
            }
        }
    });
});

输入响应==成功块，现在是我发现强制的唯一解决方案下载一个文件而不启动弹出窗口（通过window.open - 被Chrome阻止），是使用window.location.assign如上所示。这是正确的方法来强制通过JS的文件下载吗？

The response=='success' block gets entered, and for now the only solution I found to force a download of a file without launching a pop up window (through window.open - which gets blocked by Chrome anyway), is to use window.location.assign as shown above. Is this the correct way of going about forcing a file download through JS??

但是，使用window.location.assign方法我只能下载1个文件，如果我尝试用两个mp3插入两行，但不行。 AKA：

However, using the window.location.assign method I can only download 1 file, and if I try to put in two lines with two mp3s, it doesn't work. AKA:

window.location.assign('http://song1.mp3');
window.location.assign('http://song2.mp3');

我不希望用户在提交表单以下载后必须点击另一个链接.mp3 / .zip，我想尝试在JS / jQuery中做所有这些。

I do not want the user to have to click on another link after submitting the form to have to download the .mp3/.zip, I want to try to do it all in JS/jQuery.

我想到的最终方法是响应==成功浏览器点击文件上的href指向mp3的两个隐藏标签。但是，似乎问题是您无法通过点击触发链接的默认操作，而只是onclick属性。

The final method I thought about was on response=='success' to have the browser click on two hidden tags on the document that had their href pointing to the mp3s. However, it seems that "The issue is that you can't trigger a link's default action via a click" with jquery, just the onclick attribute.

我应该做什么这与js？如果没有办法这样做，我应该尝试像PHP这样的东西吗？

Should I be doing this with js? If there is no way to do this, should I try something like PHP?

有关我现在的方式的任何建议或如何下载多个mp3文件的建议有帮助！

Any suggestions on the current way I do it or recommendations on how to download multiple mp3 files would be helpful!

推荐答案

为每个url创建一个iframe，下载并将iframe的源文件设置为文件url：）

create an iframe for each url to download and set the iframe's source to files url :)

var 
    urls = ['url_1.mp3', 'url_2.mp3', /* ... , */ 'url_N.mp3'],

    doLoad = function(url){
        $("<iframe />")
            .css("display", "none")
            .bind("load", function(e){
                this.src == url && $(this).remove();
            })
            .attr("src", url)
            .appendTo($(document.body));
    };

for( var i=0; i < urls.length; i++ ) {
    doLoad( urls[i] );
}
