jQuery和Google地图自动完成 [英] jQuery and google maps auto complete

问题描述

我让Google Maps自动完成功能像这样处理几个input标记:

I have Google Maps Autocomplete working on severalinput tags like this:

 <input class="controls pac-input" id="pac-input" type="text" onfocus="geolocate()" placeholder="Type custom address" />

要启用Google Maps自动完成功能，我需要以下代码:

To enable Google Maps auto-complete, I have the following code:

//https://developers.google.com/maps/documentation/javascript/examples/places-autocomplete-addressform
$(document).ready(function () {

    autocomplete = new google.maps.places.Autocomplete((document.getElementById('pac-input')), { types: ['geocode'] });

    google.maps.event.addListener(autocomplete, 'place_changed', function () {
        MyFunc();
    });

});

然后，在MyFunc()函数中，我需要执行以下操作:

And then, in the MyFunc() function I do what I need:

function MyFunc() {
    var fullAddress = autocomplete.getPlace().formatted_address;
    var input = $(this);
    //stuff that uses input
}

但是此代码有两个问题:

This code however, has two problems:

• 首先是我正在使用一个ID来影响多个输入框(我有很多输入字段).我尝试按类别选择，但失败，并显示错误未定义".如何将该功能应用于输入字段的集合?
• 我如何知道要单击哪个字段?我尝试使用jquery $(this)，但它不能正常工作. jQuery如何帮助我?

• The first is that i am using an Id, to affect multiple input boxes (I have many input fields). I tried selecting by class but it fails with error ´undefined´. How can I apply that function to a collection of input fields?
• How do I know which field is being clicked? I tried using the jquery $(this) but it aint working. How can jQuery help me ?

提前谢谢！

推荐答案

您实际上不需要jQuery.这是一个仅使用javascript的工作示例:

You don't really need jQuery for this. Here is a working example using only javascript:

HTML:

<input class="autocomplete" id="ac1" placeholder="Enter your address" type="text"></input>
<input class="autocomplete" id="ac2" placeholder="Enter your address" type="text"></input>
<input class="autocomplete" id="ac3" placeholder="Enter your address" type="text"></input>

JavaScript:

JavaScript:

var acInputs = document.getElementsByClassName("autocomplete");

for (var i = 0; i < acInputs.length; i++) {

    var autocomplete = new google.maps.places.Autocomplete(acInputs[i]);
    autocomplete.inputId = acInputs[i].id;

    google.maps.event.addListener(autocomplete, 'place_changed', function () {
        console.log('You used input with id ' + this.inputId);
    });
}

JSFiddle演示

如果要使用jQuery，可以尝试以下方法:

If you want to do it with jQuery then you can try this way:

$('.autocomplete').each(function() {

    var autocomplete = new google.maps.places.Autocomplete($(this)[0]);
    autocomplete.inputId = $(this).attr('id');

    google.maps.event.addListener(autocomplete, 'place_changed', function () {
        console.log('You used input with id ' + this.inputId);
    });
});
