做项目用到图片上传，遇到一个别人写的不错的插件，插件小，方便，在这写一下保存方便以后再次用到
var u1 = new UploadPic();
??u1.init({
??????selector: ‘#fileImage‘,
??????callback: function(base64,input,u) {
??????????$.ajax({
??????????????url: baseUrl+‘/api/v1/file/uploadBase64File‘,
??????????????data: {imageFile: base64, fileType: ‘0‘, ctype: ‘local‘, ‘base64‘:‘base64‘,‘filename‘:u.fileName},
??????????????type: ‘post‘,
??????????????dataType: ‘json‘,
??????????????success: function(i) {
??????????????????alert(i.data);
??????????????????var textHtml = "<img class=‘imgFile‘ src=‘"+i.data+"‘/>"; ?
???????????$("#showImg").append(textHtml);
??????????????????//input.prev().prev().remove();
??????????????????//input.prev().attr(‘src‘,i.data).css(‘display‘,‘block‘);;
??????????????????//input.next().val(i.key);
??????????????????//jq.show_tip(‘上传成功!‘);
??????????????}
??????????})
??????},
??????loading: function() {
??????????//jq.show_tip(‘上传中!‘);
??????}
??});
