问题描述
我的jphp.php文件包含以下内容：
My jphp.php file contains the following :
<?php
$send_array = array();
$edge_number = array('a','b');
$vertex_a = array('c','d');
$send_array[0] = $edge_number;
$send_array[1] = $vertex_a;
echo json_encode($send_array);
?>
和我的JavaScript文件包含以下内容：
and my javascript file contains the following:
<html>
<head>
<script language="javascript">
function postRequest(strURL)
{
var xmlHttp;
if(window.XMLHttpRequest)
{ // For Mozilla, Safari, ...
var xmlHttp = new XMLHttpRequest();
}
else if(window.ActiveXObject)
{ // For Internet Explorer
var xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlHttp.open('GET', 'jphp.php', true);
xmlHttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
xmlHttp.onreadystatechange = function()
{
if (xmlHttp.readyState == 4)
{
var obj = jQuery.parseJSON('{"name":"John"}');
alert( obj.name === "John" ); updatepage(xmlHttp.responseText);
}
}
xmlHttp.send('jphp.php');
}
function updatepage(str)
{
document.write(str);
}
var vertex_a = new Array();
var edge_number = new Array();
var rec_array = new Array();
rec_array = {"edge_number", "vertex_a"};
//rec_array[1] = names;
for(var i=0;i<1;i++)
{
document.write(rec_array[i]);
}
$.ajax({
url: 'jphp.php'
type: 'post', // post or get method
data: {}, // if you need to pass post/get parameterds you can encode them here in JSON format
dataType: 'json', // the data type you want returned... we will use json
success: function(responseData) {
alert('edge_number='+responseData[0].join(','));
alert('vertex_a='+responseData[1].join(','));
}
});
我有恩code在PHP中的数据的数据....现在我想要的数据这两个阵列发送到JavaScript的.....我不知道正确的命令来使用。我被弄糊涂在谷歌搜索。

推荐答案
简单具体exmple使用jQuery：
Simple specific exmple using jquery:
JavaScript的网页：
The javascript page:
$.ajax({
url: 'url/of/page.php'
type: 'post', // post or get method
data: {}, // if you need to pass post/get parameterds you can encode them here in JSON format
dataType: 'json', // the data type you want returned... we will use json
success: function(responseData) {
var edge_number = responseData.edge_number;
var vertex_a= responseData.vertex_a;
var rec_array = responseData;
}
});
在你的PHP：
$send_array = array(
'edge_number' => array('a','b'),
'vertex_a' => array('c','d')
);
header('Content-type: application/json');
echo json_encode($send_array);
