有没有办法自动填充/文本填写表单字段,如用户类型,第一个谷歌位置返回值？

Question

编辑2 - 因为我没有得到第一个赏金的解决方案,我愿意给任何能够成功解决这个问题的人给予100分:)

编辑:请阅读问题!我不是问如何DO Google地方查找,所以请不要只是张贴,作为一个答案!

我使用Google Places API在地理位置表单中添加了标准字段.

<div><input class="input_standard fakeWaitlistCity" placeholder="Location" id="autocomplete"></input></div>

在用户输入时,它会显示以下建议.是否有设置也用第一个返回值填写字段？

这是它目前的样子:

这里的目标是用户不能只键入"纽约".如果他们停止打字,整个领域将已经填满"纽约,纽约,美国".

这是用户输入的理想体验:

谢谢!

更新 - 我发现了关于它的名称的讨论.

以下是我正在谈论的上述链接中的图片:

// Bind dollar signs to query selector (IE8+)
var $ = document.querySelector.bind(document);

function preventStandardForm(evt) {
    // prevent standard form from submitting
    evt.preventDefault();
}

function autoCallback(predictions, status) {
    // *Callback from async google places call
    if (status != google.maps.places.PlacesServiceStatus.OK) {
        // show that this address is an error
        pacInput.className = 'error';
        return;
    }

    // Show a successfull return
    pacInput.className = 'success';
    pacInput.value = predictions[0].description;
}


function queryAutocomplete(input) {
    // *Uses Google's autocomplete service to select an address
    var service = new google.maps.places.AutocompleteService();
    service.getPlacePredictions({
        input: input,
        componentRestrictions: {
            country: 'us'
        }
    }, autoCallback);
}

function handleTabbingOnInput(evt) {
    // *Handles Tab event on delivery-location input
    if (evt.target.id == "pac-input") {
        // Remove active class
        evt.target.className = '';

        // Check if a tab was pressed
        if (evt.which == 9 || evt.keyCode == 9) {
            queryAutocomplete(evt.target.value);
        }
    }
}

// ***** Initializations ***** //
// initialize pac search field //
var pacInput = $('#pac-input');
pacInput.focus();

// Initialize Autocomplete
var options = {
    componentRestrictions: {
        country: 'us'
    }
};
var autocomplete = new google.maps.places.Autocomplete(pacInput, options);
// ***** End Initializations ***** //

// ***** Event Listeners ***** //
google.maps.event.addListener(autocomplete, 'place_changed', function () {
    var result = autocomplete.getPlace();
    if (typeof result.address_components == 'undefined') {
        queryAutocomplete(result.name);
    } else {
        console.log(result.address_components);
    }
});

// Tabbing Event Listener
if (document.addEventListener) {
    document.addEventListener('keydown', handleTabbingOnInput, false);
} else if (document.attachEvent) { // IE8 and below
    document.attachEvent("onsubmit", handleTabbingOnInput);
}

// search form listener
var standardForm = $('#search-shop-form');
if (standardForm.addEventListener) {
    standardForm.addEventListener("submit", preventStandardForm, false);
} else if (standardForm.attachEvent) { // IE8 and below
    standardForm.attachEvent("onsubmit", preventStandardForm);
}
// ***** End Event Listeners ***** //

更新:

注意:根据您的要求,Google地方可以选择任何选项.因此,您可以根据需要更改超时秒数.我假设300ms我会得到建议下拉.

$("#find").click(function(){
                  $("#geocomplete").trigger("geocode");
                });
         	
              $(function(){
                $("#geocomplete").geocomplete()        
                
              });
            $('.autoc').bind('keyup', function(e) {	  
            if(e.keyCode==13){
         $('#find').click()
            }else{
         setTimeout(function(){ 
         		var inputVal = $("#geocomplete").val();
         		var inpt = $("#geocomplete");
         		if( inputVal != "" ){
         		
         			var firstRowVal = firstRowValue();
         			if( firstRowVal != "" ){
         				if(firstRowVal.toLowerCase().indexOf(inputVal.toLowerCase()) === 0){
         					inpt.val(firstRowVal);//change the input to the first match
         					inpt[0].selectionStart = inputVal.length; //highlight from end of input
         					inpt[0].selectionEnd = firstRowVal.length;//highlight to the end
         				}
         			}
         		}
         	}, 300);// please change this 300 as per your internet connection speed.
         }
         });
         
         function firstRowValue() {
              var selected = '';
              // Check if any result is selected.
              if ($(".pac-item-selected")[0]) {
                selected = '-selected';
              }
         
              // Get the first suggestion's text.
              var $span1 = $(".pac-container:visible .pac-item" + selected + ":first span:nth-child(2)").text();
              var $span2 = $(".pac-container:visible .pac-item" + selected + ":first span:nth-child(3)").text();
         
              // Adds the additional information, if available.
              var firstResult = $span1;
              if ($span2) {
                firstResult += " - " + $span2;
              }
         
              return firstResult;
            }
