由于缺乏数据库知识,所以图片只能上传到页面上进行预览功能。同样的,没有进行美化,只是实现了基础功能,后期会处理美化功能,然后将数据传到数据库进行储存,把这一块做成小插件,push到github上。
var imageElem = document.getElementById('imageElem'),
selectImages = document.getElementById('selectImages'),
imagesList = document.getElementById('imagesList');
loadList = [];
selectImages.addEventListener('click',function (e) {
if(imageElem)
imageElem.click();
},false);
function handles(files) {
if(!files.length) {
imagesList.innerHTML = "<p>未选择图片</p>";
} else {
imagesList.innerHTML = "";
var list = document.createElement('ul');
list.classList.add('row');
imagesList.appendChild(list);
for(var i = 0; i < files.length; i++) {
var li = document.createElement('li');
li.style.marginTop = "10px";
li.classList.add('col-md-4');
list.appendChild(li);
var info = document.createElement('img');
info.src = "img/删除筛选项.png";
info.alt = "删除";
//li.appendChild(info);
info.style.cursor = "pointer";
info.addEventListener('click',function () {
var parent = this.parentNode;
parent = parent.parentNode;
parent.removeChild(this.parentNode);
});
var img = document.createElement('img');
img.src = window.URL.createObjectURL(files[i]);
img.onload = function () {
loadList.push(this.src);
}
//li.appendChild(img);
img.setAttribute('width','200'); //
img.setAttribute('height','150');
img.style.position = 'absolute';
img.style.zIndex = '-1';
var imageWidth = Math.floor(parseInt(img.getAttribute('width')));
var infoSize = imageWidth * 0.10;
info.setAttribute('width',infoSize + '');
info.setAttribute('height','auto');
info.style.marginBottom = infoSize * 1 + 'px';
info.style.marginLeft = imageWidth * 0.9 + 'px';
li.style.width = img.getAttribute('width') * 1.1 + 'px';
li.style.height = img.getAttribute('width') * 1.1 + 'px';
li.appendChild(img);
li.appendChild(info);
}
}
}
效果如下:
