我使用AJAX异步调用返回的JSON对象的序列化大阵(约75kbs或80K字)的PHP脚本。每次我尝试并返回它击中一个3000个字符的限制。是否有设置在服务器上或在jQuery的Ajax实现随时随地的最大尺寸是多少?
编辑:3'000限制是一个浏览器限制,FF拥有10000个字符的限制和Safari没有限制。我猜有这个没有修好除了改变我的code分裂/减少返回的数据。
解决方案您可以分割你的JSON和部分用$阿贾克斯部分
我做了一个例子,你
HTML端:
<!DOCTYPE HTML>
< HTML LANG =EN>
< HEAD>
<元的charset =UTF-8>
<冠军>文件< /标题>
<脚本SRC =jquery.js和>< / SCRIPT>
<脚本>
$(文件)。就绪(函数(){
window.result_json = {};
$获得(x.php?部分=尺寸功能(数据){
VAR数=数据;
对于(VAR I = 0; I< =计数;我++){
$阿贾克斯({
数据类型:JSON,
网址:x.php
异步:假的,
数据:部分=+ I,
成功:功能(数据){
$ .extend(window.result_json,数据);
}
});
};
执行console.log(window.result_json);
});
});
< / SCRIPT>
< /头>
<身体GT;
< /身体GT;
< / HTML>
PHP端(文件名是x.php):
< PHP
如果(使用isset($ _ GET ['部分'])){
功能send_part_of_array($数组,$部分,$哞){
回声json_en code(array_slice($数组,$部分* $哞,哞$,真正的),JSON_FORCE_OBJECT);
}
$ max_of_one = 3;
$ =一个阵列(一,B,C,D,E,F,G,H,I,J);
如果($ _ GET ['部分'] =='大小'){
回声轮(计数($ A)/ $ max_of_one);
}其他{
send_part_of_array($ A $ _ GET ['一部分'],$ max_of_one);
}
}
?>
首先使用 $。获得
(部分=大小),检查有多少片。
其次与 $。阿贾克斯
(部分=(INT)PART-NUMBER),在for循环中得到JSON之一的部分由一个
最后以 $。延长
在for循环玛吉新获得的JSON和 window.result_json
注意: $ max_of_one
变量确定多少片发布
I am using AJAX to asynchronously call a PHP script that returns a large serialized array of JSON objects (about 75kbs or 80k characters). Every time I try and return it it hits a 3000 character limit. Is there a maximum size set anywhere on servers or within jQuery's ajax implementation?
EDIT: the 3'000 limit is a Chrome limit, FF has a 10'000 character limit and Safari has no limit. I'm guessing there is no fix for this apart from changing my code to split/lessen the return data.
解决方案You can split your JSON and get with $.ajax part by part
I made an example for you
Html side :
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<script src="jquery.js"></script>
<script>
$(document).ready(function() {
window.result_json = {};
$.get("x.php?part=size",function(data){
var count = data;
for (var i = 0; i <= count; i++) {
$.ajax({
dataType: "json",
url: "x.php",
async: false,
data: "part="+i,
success: function(data){
$.extend(window.result_json,data);
}
});
};
console.log(window.result_json);
});
});
</script>
</head>
<body>
</body>
</html>
PHP side (file name is x.php) :
<?php
if(isset($_GET['part'])){
function send_part_of_array($array,$part,$moo){
echo json_encode(array_slice($array, $part * $moo,$moo,true),JSON_FORCE_OBJECT);
}
$max_of_one = 3;
$a = array("a","b","c","d","e","f","g","h","i","j");
if($_GET['part'] == 'size'){
echo round(count($a) / $max_of_one);
}else{
send_part_of_array($a,$_GET['part'],$max_of_one);
}
}
?>
Firstly with $.get
(part=size), check how many slices.
Secondly with $.ajax
(part=(int)PART-NUMBER) , in for loop get the parts of JSON one by one
Lastly with $.extend
in for loop marge new getting JSON and old JSON elements in window.result_json
NOTE: $max_of_one
variable determine how many slices to post.
