CSS:
.imgBox,.imgBox1 { float: left; margin-right: 20px; margin-top: 20px; position: relative; width: 182px; height: 142px; border: 1px solid red; overflow: hidden; } .imgBox1{border: 1px solid blue; } .imgnum{ left: 0px; top: 0px; margin: 0px; padding: 0px; } .imgnum input,.imgnum1 input { position: absolute; width: 182px; height: 142px; opacity: 0; } .imgnum img,.imgnum1 img { width: 100%; height: 142px; } .close,.close1 { color: red; position: absolute; left: 170px; top: 0px; display: none;}
JS:
$(document).ready(function () { $(".filepath").on("change",function() { alert($('.imgBox').length); var srcs = getObjectURL(this.files[0]); //获取路径 $(this).nextAll(".img1").hide(); //this指的是input $(this).nextAll(".img2").show(); //fireBUg查看第二次换图片不起做用 $(this).nextAll('.close').show(); //this指的是input $(this).nextAll(".img2").attr("src",srcs); //this指的是input $(this).val(''); //必须制空 $(".close").on("click",function() { $(this).hide(); //this指的是span $(this).nextAll(".img2").hide(); $(this).nextAll(".img1").show(); }) }) }) function getObjectURL(file) { var url = null; if (window.createObjectURL != undefined) { url = window.createObjectURL(file) } else if (window.URL != undefined) { url = window.URL.createObjectURL(file) } else if (window.webkitURL != undefined) { url = window.webkitURL.createObjectURL(file) } return url }; $(function() { $("#img").on("change",".filepath1",function() { //alert($('.imgBox1').length); var srcs = getObjectURL(this.files[0]); //获取路径 alert(srcs); //this指的是input /* $(this).nextAll(".img22").attr("src",srcs); //this指的是input $(this).nextAll(".img22").show(); //fireBUg查看第二次换图片不起做用*/ var htmlImg='<div class="imgBox1">'+ '<div class="imgnum1">'+ '<input type="file" class="filepath1" />'+ '<span class="close1">X</span>'+ '<img src="btn.png" class="img11" />'+ '<img src="'+srcs+'" class="img22" />'+ '</div>'+ '</div>'; $(this).parent().parent().before(htmlImg); $(this).val(''); //必须制空 $(this).parent().parent().prev().find(".img11").hide(); //this指的是input $(this).parent().parent().prev().find('.close1').show(); $(".close1").on("click",function() { $(this).hide(); //this指的是span $(this).nextAll(".img22").hide(); $(this).nextAll(".img11").show(); if($('.imgBox1').length>1){ $(this).parent().parent().remove(); } }) }) })扩展:这里用到了许多jQuery选择器和属性设置
