可以使用jquery里面的ajax中的jsonp的方式来访问就可以了。代码如下：
<span 1</span> <span $.ajax({
</span><span 2</span> url: 'your url'<span ,
</span><span 3</span> data: {'xx' : 'xx', 'xx2' : 'xx2'<span },
</span><span 4</span> success: <span function</span><span (data){
</span><span 5</span> <span //</span><span 成功后执行的</span>
<span 6</span> <span },
</span><span 7</span> type:'GET'<span ,
</span><span 8</span> dataType: 'jsonp',<span //</span><span 重要的是这个</span>
<span 9</span> jsonp: "callback"<span ,
</span><span 10</span> jsonpCallback:"jsonpReturn"
<span 11</span> });
php中可以这样写：
<span 1</span> <span function</span><span login()
</span><span 2</span> <span {
</span><span 3</span> <span return</span> 'jsonpReturn('.jsondecode(<span $array</span>).')'<span ;
</span><span 4</span> }
