从javascript中的csv文件中的坐标使用GoogleMaps API [英] Use GoogleMaps API from coordinates in a csv file in javascript
本文介绍了从javascript中的csv文件中的坐标使用GoogleMaps API的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在csv中的数据是这样的。
latitude1，longitude1，latitude2，longitude2，latitude3，longitude3等。
latitude1，longitude1，latitude2，longitude2，latitude3，longitude3等。
latitude1，longitude1，latitude2，longitude2，latitude3，longitude3等。
..........等等。
其中每行代表一条路线，latitude-x和longitude-x代表一个位置。我希望你能得到我的观点。
我混合了我从w3school，google官方网站，stackoverflow等许多代码，然后我修改它的代码。到目前为止，我得到的是以下内容。
<！DOCTYPE html>< html>< head& < script src =http://maps.googleapis.com/maps/api/js> < / script> < / head>< body> < input type =filename =fileid =file> < div id =googleMapstyle =width：800px; height：580px;>< / div> < script type =text / javascript> var coordinates = []; document.getElementById（'file'）。onload = function（）{var file = this.files [0]; var reader = new FileReader（）; reader.onchange = function（progressEvent）{//整个文件//console.log(this.result）; var lines = this.result.split（'\\\
'）; for（var line = 0; line< lines.length; line ++）{var point = this.result.split（'，'）; varcount = 0; for（var dua = 0; dua< point.length; dua ++）{if（dua％2 == 0）{var latitude = point [dua]; } else {var longitude = point [dua]; coordinates [count] = new google.maps.LatLng（latitude +，+ longitude）; console.log（coordinates [count]）; count ++; }}}}; reader.readAsText（文件）; }; function getCoor（）{return coordinates; } function initialize（）{var mapProp = {center：new google.maps.LatLng（8.611911,41.146056），zoom：6，mapTypeId：google.maps.MapTypeId.ROADMAP}; var map = new google.maps.Map（document.getElementById（googleMap），mapProp）; var myTrip = []; var coordinates = getCoor（）; for（var c = 0; c >
正如你所看到的，我将从csv文件到每个行的坐标存储到数组坐标[count]。现在我想要每一行坐标传递到initialize（）函数，所以它可以通过API处理。但是我很困惑，在这一点上，特别是看到如何通过自己的函数读取文件，我不能把它传出来。我希望你得到我的意思，只是下降一个意见，如果你不明白的东西。非常感谢。
解决方案
- 您需要等待DOM呈现搜索它的元素（在initialize函数中使用document.getElementById移动任何内容）。
- 您的代码处理文件内容有问题，一个
count] = new google.maps.LatLng（latitude +，+ longitude）;无效，google.maps.LatLng使用两个数字作为参数，而不是以逗号分隔的字符串。
代码段：
; function getCoor（）{return coordinates;} function handle_files（files）{for（i = 0; i< files.length; i ++）{file = files [i]; console.log（file）; var reader = new FileReader（）; ret = []; reader.onload = function（e）{console.log（e.target.result）; var lines = e.target.result.split（'\\\
'）; var bounds = new google.maps.LatLngBounds（）; for（var line = 0; line< lines.length; line ++）{var point = lines [line] .split（'，'）; var count = 0; var coordinates = []; for（var dua = 0; dua< point.length; dua ++）{if（dua％2 == 0）{var latitude = point [dua]; } else {var longitude = point [dua]; coordinates [count] = new google.maps.LatLng（latitude，longitude）; console.log（coordinates [count]）; count ++; }} var myTrip = []; for（var c = 0; c
html，body，＃googleMap {height：100％; width：100％; margin：0px; padding：0px}
< script src = //maps.googleapis.com/maps/api/js\"></script><input type =filename =fileid =fileonchange =handle_files（this.files）/ < div id =googleMap>< / div>
用2个条目测试文件内容：

To be honest, I am not very familiar with JavaScript. But now I really need to use it to map a set of coordinates stored in my csv file, so I'll need JavaScript and GoogleMaps API.
The data I have in my csv is like this.
latitude1, longitude1, latitude2, longitude2, latitude3, longitude3, so on.
latitude1, longitude1, latitude2, longitude2, latitude3, longitude3, so on.
latitude1, longitude1, latitude2, longitude2, latitude3, longitude3, so on.
.......... so on.
Where each line represents a route and latitude-x and longitude-x represent a location. I hope you get my point.
I kind of mixed the code I got from w3school, google official site, stackoverflow and many others, then I modified it. And what I got so far is the following.
<!DOCTYPE html>

As you can see, I store the coordinates I got per line from my csv file to array coordinate[count]. Now I want every line of coordinate to be passed to the initialize() function so it can be processed through the API. But I am confused at this point, especially seeing how the file is read through its own function, and I can't pass it out. I hope you get what I mean, just drop a comment if you don't understand something. Thank you very much.

Using the file reader code from the answer to Chrome FileReader
- you need to wait for the DOM to be rendered before searching it for elements (move anything using document.getElementById inside the initialize function).
- You have issues with your code for processing the file contents, for one
coordinates[count] = new google.maps.LatLng(latitude+","+longitude);is not valid, the google.maps.LatLng takes two numbers as arguments, not a comma separated string.
code snippet:
var map;
function getCoor() {
return coordinates;
}
function handle_files(files) {
for (i = 0; i < files.length; i++) {
file = files[i];
console.log(file);
var reader = new FileReader();
ret = [];
reader.onload = function(e) {
console.log(e.target.result);
var lines = e.target.result.split('\n');
var bounds = new google.maps.LatLngBounds();
for (var line = 0; line < lines.length; line++) {
var point = lines[line].split(',');
var count = 0;
var coordinates = [];
for (var dua = 0; dua < point.length; dua++) {
if (dua % 2 == 0) {
var latitude = point[dua];
} else {
var longitude = point[dua];
coordinates[count] = new google.maps.LatLng(latitude, longitude);
console.log(coordinates[count]);
count++;
}
}
var myTrip = [];
for (var c = 0; c < coordinates.length; c++) {
myTrip.push(coordinates[c]);
bounds.extend(coordinates[c]);
}
map.fitBounds(bounds);
//console.log(myTrip);
var flightPath = new google.maps.Polyline({
path: myTrip,
strokeColor: "#0000FF",
strokeOpacity: 0.8,
strokeWeight: 8
});
flightPath.setMap(map);
}
}
reader.onerror = function(stuff) {
console.log("error", stuff);
console.log(stuff.getMessage());
}
reader.readAsText(file); //readAsdataURL
}
}
function initialize() {
var mapProp = {
