【问题描述】:
我有 4 个输入表单元素,我想从输入同级元素中选择一个元素,其值已更改(准备上传)。但我的语法不起作用:
HTML:
<div style="overflow:hidden; position: relative; display: inline-block;" class="fileinput-wrapper">
<div style="background:url(http://localhost/project/assets/images/ajax-loader.gif) no-repeat center center" data-provides="fileinput" class="fileinput fileinput-new">
<div style="width: 200px; height: 130px;background:url(http://localhost/project/assets/images/upload_a_photo.png) no-repeat center center" data-trigger="fileinput" class="fileinput-preview thumbnail">
</div>
</div>
<input type="file" name="photos[]" tabindex="-1" style="opacity: 0; position: absolute; z-index: -1; left: -367.5px; top: 80.9333px;">
</div>
JS:
$("input[type=file]").on('change',function(){
$(this).siblings('.fileinput-preview').css('background','');
});
