样式三
*可以通过JQ注册change事件以便获取选择的文件或图片,在chang事件里面通过 this.files获取选择的文件等,也可像样式三代码中一样通过JS中onchange事件获取,
*有时text-align:center,并不能使其居中时可以尝试用margin-left:30%;margin-right:30%;
$("#imgFlie").live("change", function () { var data = this.files; //var data = document.getElementById('imgFlie').files;js获取 $(this).clone().replaceAll(file = this); //每次选中都保存旧元素,并使用新的控件替换(解决紧邻的二次不能选择同一图片) $.each(data, function (key, value) { var objUrl = getObjectURL(value); if (objUrl) { var img = new Image(); img.src = objUrl; img.onload = function () { var size = img.width + 'x' + img.height; $("#ImageDiv").append('<figure><div>' + '<a href=' + '"' + objUrl + '"' + 'data-size=' + '"' + size + '"' + '>' + '<img class="WorkOrderimageNew" style="height:90px;90px;" src=' + '"' + img.src + '"' + '>' + '</a>' + '</div>' + '<figcaption style="display:none;">' + '图片' + //'<button style="float:right;" onclick=DeleteImage("' + value + '"' + //',' + //'"' + value + '")>删除图片(手机端需要注册触摸事件)</button> ' + '</figcaption></figure>' ) }; } }); });
function showPicture(files) { // var files = document.getElementById('imgFlie').files; for (var i = 0; i < files.length; i++) { var file = files[i]; if (!/image/w+/.test(file.type)) { return false; } var url = getObjectURL(file) if (url) { var img = new Image(); img.src = url; img.onload = function () { var size = img.width + 'x' + img.height; $("#ImageDiv").append('<figure><div>' + '<a href=' + '"' + img.src + '"' + 'data-size=' + '"' + size + '"' + '>' + '<img class="WorkOrderimageNew" style="height:40px;40px;" src=' + '"' + img.src + '"' + '>' + '</a>' + '</div>' + '<figcaption style="display:none;">' + '这是的图片名' + '"' + file.name + '"' + '</figcaption></figure>' ) } } } }
