JSON结果从address_components获取国家 [英] JSON result get country from address_components
问题描述
您是JSON的新手，我想知道是否可以从此API的JSON结果中调用国家/地区":
Hi new to JSON and I was wondering if I can call the "country" from this API's JSON result: http://maps.google.com/maps/api/js?sensor=true&libraries=places
我尝试使用一个获取JSON结果address_components的最后一部分的循环，但我意识到国家/地区"的位置因用户输入而异
I tried to use a loop that gets the last part of the JSON result address_components but I realized that the location of the "country" varies from the user's input
详细说明:
方案1:
用户输入:
736 Lockhart Court，Harristown QLD 4350，澳大利亚
To elaborate:
Scenario 1:
USER's INPUT:
736 Lockhart Court, Harristown QLD 4350, Australia
结果:
澳大利亚//这是正确的
Result:
Australia //this is correct
方案2:
用户输入:
美国弗吉尼亚州汉普顿的兰利空军基地
Scenario 2:
USER's INPUT:
Langley Air Force Base, Hampton, VA, United States
结果:
弗吉尼亚////不正确
Result:
Virginia //not correct
我当前的代码获取了address_components数组的最后一个索引，我想知道是否可以做这样的事情 * data.results [0] .address_components [country] .long_name; * ，但我只是不知道正确的方法.
My current code gets the last index of the array address_components and I am wondering if I can just do something like this *data.results[0].address_components[country].long_name;*, but I just don't know the proper way.
代码:
<html>
<head></head>
<title></title>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true&libraries=places"></script>
<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#btn1 ").click(function() {
var address=encodeURI($('#userInput').val());
var url='https://maps.googleapis.com/maps/api/geocode/json?address='+address+'&sensor=true';
$.getJSON(url, function(data){
for(var row=0; row<data.results.length;row++){
document.getElementById('res').value = (data.results[row].address_components[data.results[row].address_components.length-2].long_name);
}
});
});
});
</script>
<body>
<input type="text" id="res">
<input type="text" name="userInput" id="userInput" />
<input type="button" id="btn1" value="Load Data" />
</body>
</html>
如何在不依赖address_components索引的情况下获取特定的(国家/地区，街道编号等)元素?
How can I get a specific(country,street number etc) element without relying on the address_components index?
推荐答案
在您的情况下，您将必须手动迭代数组并检查types数组是否包含'country'.您可以将 array.indexof 用于这个.
in your case you will have to manually iterate the array and check that the types array contains 'country'. You can use array.indexof for this.
for(var row=0; row<data.results.length;row++){
var item = data.results[row];
for( var i = 0; i< item.address_components.length; i++) {
var component = item.address_components[i];
if( component.types.indexof('country') != -1) {
document.getElementById('res').value = component.long_name;
}
}
}
