我有一个index.php，我从那里访问noun_phreph.php以返回一个变量。现在，我必须将返回的变量从non_phrase.php传递到另一个php文件placeapi.php以执行特定任务。
index.php
if(dialog.indexOf("restaurant")!=-1 ){
$.ajaxSetup({async: false});
showText="";
sayText="";
$.ajax({
url: "noun_phrase.php",
data: {text: dialog},
success: function(data) {
nlp = data;
findPlace(nlp);
}
});
}
function findPlace(x){
name = x;
$.ajax({
url: "placeapi.php",
data: {text: name},
success: function (data){
}
});
}
placeapi.php

我想将从noun_phase.php检索到的数据传递到placeapi.php的javaScript函数，并获取位置，以便我可以在某个地方显示
您只需在构造函数google.maps.LatLng中回显该值
function initialize() {
var city = new google.maps.LatLng(<?php echo $_POST['latitude'] ?>,<?php echo $_POST['latitude'] ?>);
// longitude and latitude are part of `npl`
map = new google.maps.Map(document.getElementById('map-canvas'), {
center: city,
zoom: 15
});
var request = {
location: city,
radius: 500,
types: ['hotel']
};
确保在ajax 中添加method:POST
如果您想通过javascript访问，请向noun_phrase.php发送get请求。并回显或返回noun_phrase.php的响应并从placeapi.php获得此响应
