我有一个过滤器返回一个 youtube 嵌入,它有一个链接到模块的包装器。我的问题是过滤器返回模块永远不会应用于返回的 html,想知道如何强制它观看/重新编译。
筛选:
angular
.module( "filters" )
.filter( "youtubeFilter", [ "$filter", "$sce",
function ( $filter, $sce )
{
"use strict";
return function( message )
{
var re = /https?:\/\/(?:[0-9A-Z-]+\.)?(?:youtu\.be\/|youtube(?:-nocookie)?\.com\S*[^\w\s-])([\w-]{11})(?=[^\w-]|$)(?![?=&+%\w.-]*(?:['"][^<>]*>|<\/a>))[?=&+%\w.-]*/ig;
message = message.replace(re, "<div fitvids><iframe width='640' height='360' src='//www.youtube.com/embed/$1' frameborder='0' allowfullscreen></iframe></div>");
// message = "";
return $sce.trustAsHtml( message );
} ;
}
] );
模块:
angular.module('fitVids', []).directive('fitVids', [function() {
'use strict';
if (!document.getElementById('fit-vids-style')) {
var div = document.createElement('div');
var ref = document.getElementsByTagName('base')[0] || document.getElementsByTagName('script')[0];
var cssStyles = '­<style>.fluid-width-video-wrapper{width:100%;position:relative;padding:0;}.fluid-width-video-wrapper iframe,.fluid-width-video-wrapper object,.fluid-width-video-wrapper embed {position:absolute;top:0;left:0;width:100%;height:100%;}</style>';
div.className = 'fit-vids-style';
div.id = 'fit-vids-style';
div.style.display = 'none';
div.innerHTML = cssStyles;
ref.parentNode.insertBefore(div, ref);
}
return {
restrict: 'A',
link: function (scope, element, attr) {
var selectors = [
"iframe[src*='player.vimeo.com']",
"iframe[src*='youtube.com']",
"iframe[src*='youtube-nocookie.com']",
"iframe[src*='kickstarter.com'][src*='video.html']",
"object",
"embed"
];
var videos;
if (attr.customSelector) {
selectors.push(attr.customSelector);
}
videos = element[0].querySelectorAll(selectors.join(','));
angular.forEach(videos, function (item) {
var $item = angular.element(item);
var height, width, aspectRatio;
if (item.tagName.toLowerCase() === 'embed' &&
($item.parent().tagName === 'object' && $item.parent().length) ||
$item.parent().hasClass('.fluid-width-video-wrapper')) {
return;
}
height = (item.tagName.toLowerCase() === 'object' || $item.attr('height')) ? parseInt($item.attr('height'), 10) : $item.height();
width = !isNaN(parseInt($item.attr('width'), 10)) ? parseInt($item.attr('width'), 10) : $item.width();
aspectRatio = height / width;
if (!$item.attr('id')) {
var videoID = 'fitvid' + Math.floor(Math.random()*999999);
$item.attr('id', videoID);
}
$item.wrap('<div class="fluid-width-video-wrapper" />').parent().css('padding-top', (aspectRatio * 100) + "%");
$item.removeAttr('height').removeAttr('width');
});
}
};
}]);
