这是一个让我们有点疯狂的事情。我们从 jQuery UI 页面http://jqueryui.com/autocomplete/#remote-jsonp实现了 JSONP 的示例脚本,然后就在它旁边,我们编写了一个最小修改的版本。

这是踢球者。jQuery ui 的脚本可以在 IE 中运行,而我们的脚本只能在 Firefox、Chrome 等中运行

唯一的区别是我们的数据源。

当我们将数据发送给客户端时,我们需要对数据做一些神奇的事情吗?我们已经尝试将它包装在命名函数等中。

对于傻笑,这是工作 json 服务的输出

{"totalResultsCount":12958,"geonames":[{"countryName":"Russia","adminCode1":"33","fclName":"city, village,...","countryCode":"RU","lng":51.4913,"fcodeName":"seat of a second-order administrative division","toponymName":"Uni","fcl":"P","name":"Uni","fcode":"PPLA2","geonameId":478996,"lat":57.751,"adminName1":"Kirov","population":4767},{"countryName":"Russia","adminCode1":"54","fclName":"city, village,...","countryCode":"RU","lng":72.622724,"fcodeName":"populated place","toponymName":"Uki","fcl":"P","name":"Uni","fcode":"PPL","geonameId":1488608,"lat":56.991135,"adminName1":"Omsk","population":0},{"countryName":"Philippines","adminCode1":"07","fclName":"city, village,...","countryCode":"PH","lng":124.3252,"fcodeName":"populated place","toponymName":"Union","fcl":"P","name":"Union","fcode":"PPL","geonameId":1680262,"lat":10.6695,"adminName1":"Central Visayas","population":4581},{"countryName":"Philippines","adminCode1":"13","fclName":"city, village,...","countryCode":"PH","lng":126.1102778,"fcodeName":"populated place","toponymName":"Union","fcl":"P","name":"Union","fcode":"PPL","geonameId":1680267,"lat":9.7566667,"adminName1":"Caraga","population":2368}]}

这是我们服务器的输出

{"addresses":[{"address":"3666 LACEY WOODS PARK"},{"address":"3666 LACON RD"},{"address":"3666 LAKESTONE CIR"},{"address":"3666 E LINKS CIR"}]}

console.log除非您打开开发人员工具或实施解决方法,否则在 IE 中不起作用:

IE8 中的 console.log 发生了什么?

取出或注释掉所有console.log引用或按 F12 或使用解决方法并在 IE 中重试。

IE 中的 F12 将显示任何 js 错误,并且对于解决此类问题非常有用,即使它不是console.log导致问题的语句。

JSONP 协议是一个跨站点脚本即席协议。当您查询的域和用于下载页面的域是 2 个不同的域时,需要它。我猜你的问题是浏览器不允许你直接请求 192.168.50.78 ,因为你原来的域是别的东西。注意你使用 json 的区别,remote-jsonp 使用 jsonp。
