Google Maps API - 将 php 变量设置为 javascript 变量
我正在使用 Google Maps API 和 W3C 标准来获取用户的地理位置。我将其设置为基础 - 使用 [Google 文档][1] 中的代码。
现在我正在将其集成到我的网站中,并需要将其输入到我的 mysql 数据库中。我想将 PHP 变量设置为 JavaScript 变量(基本上将 PHP 变量设置为纬度和经度)。但我没有成功做到这一点。
编辑:
基本上我想使 $phpvar
= $jsvar
。创建一个 php 变量 = 我的 javascript 变量。
这是代码:
var initialLocation;
var siberia = new google.maps.LatLng(60, 105);
var newyork = new google.maps.LatLng(40.69847032728747, -73.9514422416687);
var browserSupportFlag = new Boolean();
function initialize() {
var myOptions = {
zoom: 6,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
// Try W3C Geolocation (Preferred)
if(navigator.geolocation) {
browserSupportFlag = true;
navigator.geolocation.getCurrentPosition(function(position) {
initialLocation = new google.maps.LatLng(position.coords.latitude,position.coords.longitude);
map.setCenter(initialLocation);
}, function() {
handleNoGeolocation(browserSupportFlag);
});
// Try Google Gears Geolocation
} else if (google.gears) {
browserSupportFlag = true;
var geo = google.gears.factory.create('beta.geolocation');
geo.getCurrentPosition(function(position) {
initialLocation = new google.maps.LatLng(position.latitude,position.longitude);
map.setCenter(initialLocation);
}, function() {
handleNoGeoLocation(browserSupportFlag);
});
// Browser doesn't support Geolocation
} else {
browserSupportFlag = false;
handleNoGeolocation(browserSupportFlag);
}
function handleNoGeolocation(errorFlag) {
if (errorFlag == true) {
alert("Geolocation service failed.");
initialLocation = newyork;
} else {
alert("Your browser doesn't support geolocation. We've placed you in Siberia.");
initialLocation = siberia;
}
map.setCenter(initialLocation);
} 任何
帮助都会很棒!请具体说明,因为我是这个 Google 地图 API 的新手。
谢谢! :)
I am using the Google Maps API and the W3C Standard to get a user's geolocation. I have it set up as basics - using the code from [Google's documentation][1].
Now I'm integrating this into my website and need it imputed into my mysql database. I want to set a PHP variable as a JavaScript variable (basically setting a PHP variable as the latitude and longitude). But I'm having no success of doing this.
EDIT:
Basically I want to make $phpvar
= $jsvar
. Making a php variable = my javascript variable.
Here's the code:
var initialLocation;
var siberia = new google.maps.LatLng(60, 105);
var newyork = new google.maps.LatLng(40.69847032728747, -73.9514422416687);
var browserSupportFlag = new Boolean();
function initialize() {
var myOptions = {
zoom: 6,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
// Try W3C Geolocation (Preferred)
if(navigator.geolocation) {
browserSupportFlag = true;
navigator.geolocation.getCurrentPosition(function(position) {
initialLocation = new google.maps.LatLng(position.coords.latitude,position.coords.longitude);
map.setCenter(initialLocation);
}, function() {
handleNoGeolocation(browserSupportFlag);
});
// Try Google Gears Geolocation
} else if (google.gears) {
browserSupportFlag = true;
var geo = google.gears.factory.create('beta.geolocation');
geo.getCurrentPosition(function(position) {
initialLocation = new google.maps.LatLng(position.latitude,position.longitude);
map.setCenter(initialLocation);
}, function() {
handleNoGeoLocation(browserSupportFlag);
});
// Browser doesn't support Geolocation
} else {
browserSupportFlag = false;
handleNoGeolocation(browserSupportFlag);
}
function handleNoGeolocation(errorFlag) {
if (errorFlag == true) {
alert("Geolocation service failed.");
initialLocation = newyork;
} else {
alert("Your browser doesn't support geolocation. We've placed you in Siberia.");
initialLocation = siberia;
}
map.setCenter(initialLocation);
}
}
Any help would be great! Please be specific with me because I'm new to this Google Map API.
Thanks! :)

您可以将 PHP 变量存储为 Javascript 变量,如下所示:
然后您可以根据需要使用该变量。如果您可以提供示例代码,我会尽力让您更准确地了解。
You can store a PHP variable as a Javascript variable like this:
You can then use this variable as required. If you can give an example code, I would try to let you know more accurately.
“想要将 PHP 变量设置为 Javascript 变量”。这还不太清楚吗?
如果您想要 PHP->Javascript,那么很简单:
对于 Javascript->PHP,则有点复杂。您必须执行一些 DOM 黑客操作才能将值插入表单值/提交表单,或者执行一些 AJAX 工作。
"want to set a PHP variable as a Javascript variable". This isn't quite clear?
If you want to go PHP->Javascript, then it's simple:
For Javascript->PHP, it's a bit more complicated. You'd have to do some DOM hacking to insert the value into a form value/submit form, or do some AJAX work.
这就是我目前为 Lat 和 Lng 设置 php 变量,然后使用 Javascript 调用它们的方式:
我正在使用 parseFloat() 函数
parseFloat
这有助于解决 Lat/Lng有些人可能会遇到 VS Code 中的对象字面量错误消息和标记/lint 错误。我希望这对您和其他人有所帮助。
This is how I currently set the php variables for Lat and Lng and then call them with Javascript:
I'm using the parseFloat() function
parseFloat
This helped solve the Lat/Lng Object Literal error messages and markup / lint errors in VS Code that some may be experiencing. I hope this helps you and others.
