为什么它没有从WeathermapAPI提醒我的信息

Question

$(document).ready(function(){

    var api="http://api.openweathermap.org/data/2.5/weather?q=dehradun,india&           APPID=ab399c2f90228bbdabc65d72b81a1b4d";

    $.getJSON(api,function(data){

        alert(data.coord.lat);

    });

});

Answer 1

There is lot of spaces in the URL query strings. Remove the blank spaces before APPID

Note: To make the below code snippet to work, I used https in the API URL because StackOverflow uses https protocol.

 $(document).ready(function(){ var api="https://api.openweathermap.org/data/2.5/weather?q=dehradun,india&APPID=ab399c2f90228bbdabc65d72b81a1b4d";; $.getJSON(api,function(data){ alert(data.coord.lat); }); });

Answer 2

Change this piece of code:

var api="http://api.openweathermap.org/data/2.5/weather?q=dehradun,india&           APPID=ab399c2f90228bbdabc65d72b81a1b4d";

to:

var api="http://api.openweathermap.org/data/2.5/weather?q=dehradun,india&APPID=ab399c2f90228bbdabc65d72b81a1b4d";

Please add the jquery cdn to your html if you haven't added it. Try this piece of code:

<script
  src="https://code.jquery.com/jquery-3.3.0.min.js"
  integrity="sha256-RTQy8VOmNlT6b2PIRur37p6JEBZUE7o8wPgMvu18MC4="
  crossorigin="anonymous"></script>
<script>

$(document).ready(function(){

    var api="http://api.openweathermap.org/data/2.5/weather?q=dehradun,india&APPID=ab399c2f90228bbdabc65d72b81a1b4d";

    $.getJSON(api,function(data){

       alert(data.coord.lat);

    });

});
</script>
