/* *作者:周祥 *时间:2014年08月19日 *介绍:图片上传预览插件 兼容浏览器(IE 谷歌 火狐) 不支持safari 当然如果是使用这些内核的浏览器都兼容 *网站:http://jquery.decadework.com http://www.oschina.net/code/snippet_1049351_26784 *QQ:200592114 *版本:1.2 *参数说明: Img:图片ID;Width:预览宽度;Height:预览高度;ImgType:支持文件类型;Callback:选择文件后回调方法; *插件说明: 基于JQUERY扩展,需要引用JQUERY库。 *使用方法: <div> <img id="ImgPr" width="120" height="120" /></div> <input type="file" id="up" /> 把需要进行预览的IMG标签外 套一个DIV 然后给上传控件ID给予uploadPreview事件 $("#up").uploadPreview({ Img: "ImgPr", Width: 120, Height: 120, ImgType: ["gif", "jpeg", "jpg", "bmp", "png"], Callback: function () { }}); 另外注意一下 使用该插件预览图片 选择文件的按钮在IE下不能是隐藏的 你可以换种方式隐藏 比如:top left 负几千像素 v1.2:更新jquery1.9以上版本 插件报错BUG */ jQuery.fn.extend({ uploadPreview: function (opts) { var _self = this , _this = $( this ); opts = jQuery.extend({ Img: "ImgPr" , Width: 100, Height: 100, ImgType: [ "gif" , "jpeg" , "jpg" , "bmp" , "png" ], Callback: function () { } }, opts || {}); _self.getObjectURL = function (file) { var url = null ; if (window.createObjectURL != undefined) { url = window.createObjectURL(file); } else if (window.URL != undefined) { url = window.URL.createObjectURL(file); } else if (window.webkitURL != undefined) { url = window.webkitURL.createObjectURL(file); } return url; } _this.change(function () { if ( this .value) { if (!RegExp( "\.(" + opts.ImgType. join ( "|" ) + ")$" , "i" ).test( this .value.toLowerCase())) { alert( "选择文件错误,图片类型必须是" + opts.ImgType. join ( "," ) + "中的一种" ); this .value = "" ; return false ; } if (navigator.userAgent.indexOf( "MSIE" ) > -1) { try { $( "#" + opts.Img).attr( ‘src‘ , _self.getObjectURL( this .files[0])); } catch (e) { var src = "" ; var obj = $( "#" + opts.Img); var div = obj.parent( "div" )[0]; _self. select (); if (top != self) { window.parent.document.body.focus(); } else { _self.blur(); } src = document.selection.createRange().text; document.selection.empty(); obj.hide(); obj.parent( "div" ).css({ ‘filter‘ : ‘progid:DXImageTransform.Microsoft.AlphaImageLoader(sizingMethod=scale)‘ , ‘width‘ : opts.Width + ‘px‘ , ‘height‘ : opts.Height + ‘px‘ }); div.filters.item( "DXImageTransform.Microsoft.AlphaImageLoader" ).src = src; } } else { $( "#" + opts.Img).attr( ‘src‘ , _self.getObjectURL( this .files[0])); } opts.Callback(); } }); } }); |
