Vue里面的v-for绑定数据改成Javascript的for循环

源：

<div id="item-news-head" class="mui-control-content mui-active">
	<ul class="mui-table-view " id="newsHead" v-for="head in heads">
			<li class="mui-table-view-cell mui-media">
				<div v-on:click="newsDetail(head)">
					<img class="mui-media-object mui-pull-left" :src="head.newsUrlImg ? head.newsUrlImg : 'images/news.jpg'">
					<div class="mui-media-body">
						<span v-text="head.newsTitle"></span>
						<p class="mui-ellipsis" v-text="head.newsSummary"></p>
					</div>
				</div>
			</li>
		</ul> 
	<!--加载更多按钮-->
	<div class="js-load-more">加载更多</div>
</div>

改：

/*使用for循环模拟SQL里的limit(offset,size)*/
for (var i = offset; i < (offset + size); i++) {
	//var imgurl = data[i].newsUrlImg ? data[i].newsUrlImg : 'images/news.jpg'
	if (data[i].newsUrlImg) {
		imgurl = data[i].newsUrlImg;
		console.log(imgurl)
	} else {
		imgurl = 'images/news.jpg'
		console.log(imgurl)
	}
	result += '<ul class="mui-table-view "  id="newsHead" >' +
				'<li class="mui-table-view-cell mui-media">' +
					'<div >' +											
						'<img class="mui-media-object mui-pull-left" src="'+imgurl+'" >' +
						'<div class="mui-media-body">' +
							'<span >' + data[i].newsTitle + '</span>' +
							'<p class="mui-ellipsis">' + data[i].newsSummary + '</p>' +
						'</div>' +
					'</div>' +
				'</li>' +
			  '</ul>'
}
