添加视频URL，并带有实时预览选项 [英] Add video URL, with live preview option

问题描述

我正在创建一个允许人们输入视频网址的表单.标准输入表单，接受如下网址:

I am creating a form which allows people to enter a video url. Standard input form, to accept a URL like:

http://video.google.com/videoplay?docid=1299927595688205543

我想添加一个按钮(在表单内，它显示[preview video]之类的内容).基本上，该按钮/链接会将在输入字段中输入的链接附加到此代码:

I would like to add a button (within the form, which says something like [preview video]). Basically that button/link appends the link they entered into the input field, to this code:

<a href="http://video.google.com/videoplay?docid=1299927595688205543&lightbox[width]=610&lightbox[height]=360" class="lightbox">google video</a >

在提交表单之前可以使用它.

This is to be available prior to form submission.

推荐答案

<form id="video_upload_form" action="">
    <label for="video_input_box">Video URL</label>
    <input type="text" id="video_input_box" value="" />

    <input type="submit" value="Add Video" />
</form>

<p><a href="#" id="video_preview" class="lightbox">Preview Video</a></p>

<script type="text/javascript">
$().ready(function(){
    $('#video_upload_form').submit(function(){
        var video_url_params = '&lightbox[width]=610&lightbox[height]=360';
        var video_url = $('#video_input_box').val() + video_url_params;
        $('#video_preview').attr('href', video_url);
        return false;
    });
});
</script>

这里也像JSFiddle一样: http://jsfiddle.net/Treffynnon/CEMpT/

Also here it is as a JSFiddle: http://jsfiddle.net/Treffynnon/CEMpT/

在将其放入预览链接之前，您需要对用户提供的URL进行一些验证，但是由于您没有在问题中寻求帮助，因此我将把这部分留给您.

You will need to do some validation on the URL supplied by the user before putting it into the preview link, but I will leave that part up to you as you have not asked for help with it in your question.
