如果你的项目需要接入文件预览项目，达到对docx、excel、ppt、jpg等文件的预览效果，那么通过在你的项目中加入下面的代码就可以
|
||||
成功实现：
|
||||
<pre style="background-color: #2f332a;color: #cccccc">
|
||||
$scope.openWin = function (fileUrl) {
|
||||
var url = configuration.previewUrl + encodeURIComponent(fileUrl);
|
||||
var winHeight = window.document.documentElement.clientHeight-10;
|
||||
$window.open(url, "_blank", "height=" + winHeight
|
||||
+ ",top=80,left=80,toolbar=no, menubar=no, scrollbars=yes, resizable=yes");
|
||||
};
|
||||
</pre>
|
||||
<b>说明:</b>
|
||||
<p>1.这里的fileUrl即是需要预览的服务器文件，一般是ufile文件</p>
|
||||
<p>2.只所以使用encodeURIComponent转码是因为ufile文件中可能会存在&等特殊字符，那么如果不转码会被浏览器处理成多参数
|
||||
这样后台获取的就不是需要预览的文件的全路径了。</p>
|
||||
<p>3.configuration.previewUrl是需要接入项目中配置文件预览项目的地址的配置
|
||||
现在开发和测试地址都是：
|
||||
http://106.75.31.215:8012/onlinePreview?url=服务器(ufile)文件路径</p>
