HomeBackend DevelopmentPHP Tutorial输入相同的JSON串为啥jquery处理结果不一样

function getOrderDishArea(){
$("#orderDishList").text('');
//var area;
//if(getItem("areaName")==null){
// area='hefei';
//}else{
// area=getItem("areaName")
//}
    document.getElementById('order_dish_info_panel').style.display = 'none';
$.jsonP({
url:'http://shegoushop.com/app/ceshi.php?m=ClientApp&a=getArea&city_domain=hefei',
url:'http://public.6tie.com/index.php?m=ClientApp&a=getArea&city_domain=hefei',

success:function(data){
alert("OK!");
if(data['msg']=="success" && data['data']!=null){

$('#order_dish_area_info_loading').hide();

var orderDishStr='';
var jsondata=data['data'];

for(var i=0;i var sum=i+1;
/*orderDishStr+='输入相同的JSON串为啥jquery处理结果不一样';*/
orderDishStr+="

';
}
$("#orderDishList").append(orderDishStr);
}else{
alert("加载区域没有数据!");
}
}
});
}

如以上所示,执行两个不同的URL,返回相同的JSON串,但是第一个URL不执行,第二个URL可以执行。


回复讨论(解决方案)

url:'http://shegoushop.com/app/ceshi.php?m=ClientApp&a=getArea&city_domain=hefei',
url:'http://public.6tie.com/index.php?m=ClientApp&a=getArea&city_domain=hefei',
success:function(data){}
这是什么用法
jsonP({})这个方法的参数是json格式吧,json格式可以给一个键名url赋值2次吗?

url:'http://shegoushop.com/app/ceshi.php?m=ClientApp&a=getArea&city_domain=hefei',

两个URL是测试的,这两个URL执行后输出相同的JSON字符串,但是只有一个URL是可以执行成功的,不知道为什么?测试时注释掉一个URL

键名(url)相同,后者把前者覆盖了,当然只会执行一个

不好意思理解错了,
js你这个是跨域的问题
叫给你提供接口的人在服务端加段跨域代码
header("Access-Control-Allow-Origin: *");

你这个页面的域名和接口域名相同就能获得数据,不同的话需要加跨域的代码,我写的这个只是一种, 网上很多的

键名(url)相同,后者把前者覆盖了,当然只会执行一个



可能我表达错了,执行时不是执行俩,是分别执行。执行一个时注释掉另一个,但是两个URL只有一个能够执行,应该是跨域问题,不知道怎么处理的,只有一个URL能够执行成功,但是俩URL抛出的json串是一样的。

这个好像只能服务端配合吧,只是js单方好像处理不了
叫服务端给加个header

如果不是自己的服务端,就只有在自己的服务端做个file_get_content();了

不好意思理解错了,
js你这个是跨域的问题
叫给你提供接口的人在服务端加段跨域代码
header("Access-Control-Allow-Origin: *");



测试了,php服务器端加上header("Access-Control-Allow-Origin: *"); 也不行。不知道url:'http://public.6tie.com/index.php?m=ClientApp&a=getArea&city_domain=hefei'为啥可以执行,测试的php文件抛出一样的JSON也不执行。应该是跨域问题,但是加这个header声明不管用。

执行第二个URL:

执行第一个URL:

<?phpheader("Access-Control-Allow-Origin: *");?><script src=scripts/jquery-1.8.3.min.js></script><script>$(function() {  $.get('http://shegoushop.com/app/ceshi.php?m=ClientApp&a=getArea&city_domain=hefei', function(d) { $('#a').html('a'+d); });  $.get('http://public.6tie.com/index.php?m=ClientApp&a=getArea&city_domain=hefei', function(d) { $('#b').html('b'+d); });});</script><div id='a'>A</div><div id='b'>B</div>

<?phpheader("Access-Control-Allow-Origin: *");?><script src=scripts/jquery-1.8.3.min.js></script><script>$(function() {  $.get('http://shegoushop.com/app/ceshi.php?m=ClientApp&a=getArea&city_domain=hefei', function(d) { $('#a').html('a'+d); });  $.get('http://public.6tie.com/index.php?m=ClientApp&a=getArea&city_domain=hefei', function(d) { $('#b').html('b'+d); });});</script><div id='a'>A</div><div id='b'>B</div>

Access-Control-Allow-Origin: *
需要每个页面都有

<?phpheader("Access-Control-Allow-Origin: *");?><script src=scripts/jquery-1.8.3.min.js></script><script>$(function() {  $.get('http://shegoushop.com/app/ceshi.php?m=ClientApp&a=getArea&city_domain=hefei', function(d) { $('#a').html('a'+d); });  $.get('http://public.6tie.com/index.php?m=ClientApp&a=getArea&city_domain=hefei', function(d) { $('#b').html('b'+d); });});</script><div id='a'>A</div><div id='b'>B</div>




已经顺利解决,这个jqmobi的JSON跨域,服务器端回调即可。服务器端直接输出JSON是不行的,要回调JS回调函数。

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Best Practices for Dependency Injection in PHPBest Practices for Dependency Injection in PHPMay 08, 2025 am 12:21 AM

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
