jQuery文件上传:是否可以使用“提交"按钮触发上传? [英] jQuery file upload: Is it possible to trigger upload with a submit button?

问题描述

我正在使用jQuery文件上传基于AJAX的上传.选择文件后，它总是开始上载.是否可以使用提交"按钮更改行为?我知道问题#35 ，但是选项beforeSend似乎被删除.

I'm using jQuery file upload for AJAX-based uploads. It always starts uploading after a file is selected. Is it possible to change the behavior to use the "submit"-button? I am aware of Issue #35, but the Option beforeSend seems to have been removed.

我正在使用基本插件，而不是完整版本版本.

I am using the Basic Plugin, not the full version.

也许我应该按照那里的建议切换到基于纯XHR的上传: jQuery上载进度和AJAX文件上载.

Maybe I should just switch to plain-XHR-based uploading as suggested there: jQuery Upload Progress and AJAX file upload.

推荐答案

如果有按钮

<button id="up_btn">Upload</button>

您可以尝试

$('#fileupload').fileupload({
    dataType: 'json',
    add: function (e, data) {            
        $("#up_btn").off('click').on('click', function () {
            data.submit();
        });
    },
});

根据评论，更好的答案是off，以避免重复的请求. (也可以使用unbind，我不检查是否是bind和unbind，但是jquery团队推荐on和off

according to comments a better answer considere off to avoid duplicated requests. (also work unbind, I do not check if is bind and unbind but jquery team recommend on and off link since 1.7)
