我有一个页面可以将大约 150 多个图像加载到一个页面中。图像的结构是这样的:
代码
<table class="form-table">
<input type="hidden" name="bgtype" id="bgtype" value="pattern"/>
<tr class="wpbp-field-patternbg">
<th style="width:20%"><label for="patternbg">Pattern</label></th>
<td><div id="wpbp-pattern-select">
<div class="description">Select a pattern you would like to be applied as the background. Click on a pattern to select it.<br>
</div>
<input class="radio" type="radio" name="patternbg" id="patternbg2" value="45degreee_fabric.png" checked='checked'>
<label for="patternbg2" class="is-loading"><a class="pattern_preview" data-img="45degreee_fabric.png" data-content="45degreee fabric"><img src="45degreee_fabric.png" alt="" class="wpbp-pattern-img "/></a></label>
<input class="radio" type="radio" name="patternbg" id="patternbg3" value="patterns/60degree_gray.png" >
<label for="patternbg3" class="is-loading"><a class="pattern_preview" data-img="60degree_gray.png" data-content="60degree gray"><img src="60degree_gray.png" alt="" class="wpbp-pattern-img "/></a></label>
<input class="radio" type="radio" name="patternbg" id="patternbg4" value="always_grey.png" >
<label for="patternbg4" class="is-loading"><a class="pattern_preview" data-img="always_grey.png" data-content="always grey"><img src="always_grey.png" alt="" class="wpbp-pattern-img "/></a></label>
</div></td>
</tr>
</table>
(我已经删除了图像的完整路径,以至少使上面的代码)
CSS 代码
#wpbp-pattern-select.is-loading {
background-image: url('../images/loading.gif');
}
#wpbp-pattern-select .is-loading img {
opacity: 0;
}
查询
var $container = $('#wpbp-pattern-select');
$imgs = $container.find('img'),
// use ImagesLoaded
$container.imagesLoaded()
.progress( onProgress )
// reset progress counter
imageCount = $container.find('img').length;
console.log( imageCount + ' properly loaded images' );
// triggered after each item is loaded
function onProgress( imgLoad, image ) {
var $item = $container.find('img');
$item.removeClass('is-loading');
}
我想要实现的是在每个单独的图像上显示一个预加载微调器(.is-loading),直到加载了某个图像。加载完成后,微调器将删除显示原始图像。
我尝试过使用 jQuery imagesLoaded 库来让它工作,但我做不到。这可以做到吗?
任何帮助将不胜感激,谢谢
