iOS上的Ajax内部500错误 [英] ajax internal 500 error on iOS

问题描述

我正在尝试使用Ajax读取文本文件，但是在ios上不起作用:仅在iOS上的proDB.txt文件上出现错误500(内部服务器错误).

I am trying to read a text file using ajax, but it doesn't work on ios : I get an error 500 (Internal Server Error) on the proDB.txt file on iOS only.

var prodata=[];
ajaxreadfile();

function ajaxreadfile() {
    return $.ajax({
            url: "proDB.txt",
            type: 'GET',
            dataType: 'text',
            headers: { "cache-control": "no-cache" },
            success: function(data){
                readfile(data);
            },
            async: false
        });
}  

function readfile(data){
    var lines=data.split(/\n/);
    var i;
    prodata.push(0);
    var fieldnames=lines[0].split(/\t/);
    for (i = 1; i < lines.length-1; ++i) {
        var fields=lines[i].split(/\t/);
        prodata.push(i);            
        var j;
        prodata[i]={};
        prodata[i]['id']=i; //auto id, there is no more 'id' column in the DB file.
        for (j = 0; j < fields.length; ++j) {
            var str=fieldnames[j];
            prodata[i][str]=fields[j];  
        }
    }

    prodata.sort(SortByName);

    resetLists(prodata);

    prodata.sort(SortById);
}

你能告诉我怎么了吗?

推荐答案

要解决此问题，我使用iOS的文件的完整路径是这样的:

To solve the problem, I use the full path to the file for iOS like this :

var request = $.ajax({
        url: dbUrl(),
        type: 'get',
        dataType: 'text',
        success: successCallback
    });

function dbUrl(){
    if(isIOS()){
        return "http://www.mysite.com/proDB.txt";
    }else{
        return "proDB.txt";
    }
}
function isIOS(){
    return (
       (navigator.userAgent.indexOf("iPhone") != -1) ||
       (navigator.userAgent.indexOf("iPod") != -1) ||
       (navigator.userAgent.indexOf("iPad") != -1)
    );
}
