标签: php jquery ajax

我正在使用来自PHP Letter的ajax文件上传插件并且正在使用jQuery 1.6.2。文件正确上传,但我无法使用从php脚本返回的JSON数据,当我检查javascript错误consolse我遇到这个错误,

  

“Uncaught TypeError:Object function(a,b){return new   e.fn.init(a,b,h)}没有方法'handleError'“

在chrome和

  

“jQuery.handleError不是函数”

在Firefox中

有没有人有类似的经历?

当你尝试使用最新版本的jQuery时。 handleError函数从库上限到V 1.5折旧。 我只需在我的ajaxfileupload.js文件中添加此函数即可解决此问题。

handleError: function( s, xhr, status, e ) {
    // If a local callback was specified, fire it
    if ( s.error ) {
        s.error.call( s.context || window, xhr, status, e );
    }

    // Fire the global callback
    if ( s.global ) {
        (s.context ? jQuery(s.context) : jQuery.event).trigger( "ajaxError", [xhr, s, e] );
    }
}

它对我来说很好。 此外,如果您尝试在同一页面上使用任何ajaxSubmit()它将无法工作,所以我使用正常的表单提交与ajxfileupload。如果有人能以同样的方式提供帮助,请告诉我。

现代jQuery没有 jQuery.handleError(s,xml,status,e)方法。

因此,如果出现错误,文件上传程序会挂起所有javascripts。

这个上传程序脚本小巧,优雅,漂亮。然而,它相当古老,jQuery从那时起就完全重新设计了ajax。下次,我将尝试使用带有进度条和拖放支持的现代复杂脚本:http://valums.com/ajax-upload/

否则,出于遗留代码或简单原因,您会发现 ajaxfileupload.js (版本2.1)的此修复程序非常有用: 请注意,不支持全局“ajaxError”事件。

我也使用这个插件,并且新版本的jQuery有些不兼容。 我在我的项目中使用了jquery-1.9.1.js。

该插件与jquery-1.2.1.js一起使用。

我在中文网站上找到了解决方案:http://chen-h.iteye.com/blog/1769457 我测试了这个版本,它的工作原理。 回调现在没问题。

我不会说中文,但我想开发人员已经为新版本的Jquery转换了这个插件。

该示例使用jQuery 1.2.1;

jQuery.handleError()被删除了一会儿,我不知道什么时候。

您需要使用较旧的jQuery版本,自行更新脚本或尝试查找最新的脚本。试试http://valums.com/ajax-upload/或搜索一些但只记得检查他们的上次更新日期!

我找到了一个类似的插件并对其进行了修改,以满足我的需求,感谢您提醒我们删除$ .handleError()

答案 5 :(得分:0)

本文很好地应用了AJAX上传,并解释了它的codeigniter。它确实对我有用,除了我必须替换

dataType:'json'

通过

dataType:'html'

似乎与json有一些问题

也相对url对我没用,所以我放了一个绝对的网址。

 url         :'http://localhost/satyam/LifeBook/places/upload_file',

并且不要忘记你需要在ajaxupload.js文件中写入handlError函数到最后。 http://www.kovloq.com/2011/10/23/ajax-upload-using-codeigniter/
