ajaxfileUpload.js兼容ie7、8、9、10、11、firefox、chrome等浏览器的js代码


因为项目需要,引入了ajaxfileUpload.js的js插件,从开始用 ,就一直问题多多,我当时是结合springmvc使用的。
如1、使用springmvc的@responseBody返回,不可以,需要改成response.getWrite().write()方法解决ie下返回的是json文件的问题。
如2、返回的结果需要eval()处理等。
如3、缺少错误函数的处理等。
如4、在同一页面上传多次,会出现遮罩层重叠,弹出框弹出多次的问题。【需要在代码中做一个计数器。】
如5、handleError方法写的不规范等问题,引起前台总报js错误
等等,使用了这个js插件,有种被坑的感觉,一直在解决各种问题。
目前这个js插件已经解决以上所有问题,网上提供的这个插件都或多或少缺少一些功能
自己痛苦了这么多,希望对使用此控件的人有用,减少一些查找和解决错误的时间。
