上传及修改
首先是前端部分：
我是用iframe层打开的上传界面然后在进行添加或修改图集主要代码：
add.html:
<input type="button" class="button bg-blue margin-left" id="image1" value="+ 浏览上传" οnclick="zpss();">
<input type="hidden" id="imgarr" value="" name="imgarr" /> 图片路径隐藏域
//打开上传页面
function zpss(){
//iframe层
layer.open({
type: 2,
title: '多图上传',
shadeClose: true,
shade: 0.1,
area: ['40%', '70%'],
content:"{:U('Product/duotu')}" //iframe的url
});
}
//上传页面接收iframe层传递回来的图片路径赋给隐藏域添加
function callbacks(imgarr){
if(imgarr != ''){
$("#imgarr").val(imgarr);
$("#yishang").css("display","block");
layer.closeAll(); //添加完成关闭上传层
}
}
iframe页面html：
