jquery – 谷歌地图初始化不与标签一起使用

我正在尝试在标签点击事件上初始化Google地图,因为目前我正在获取这样的地图：

我的代码：

(function($) {

/*
*  render_map
*
*  This function will render a Google Map onto the selected jQuery element
*
*  @type    function
*  @date    8/11/2013
*  @since   4.3.0
*
*  @param   $el (jQuery element)
*  @return  n/a
*/

function render_map( $el ) {

    // var
    var $markers = $el.find('.marker');

    // vars
    var args = {
        zoom        : 16,center      : new google.maps.LatLng(0,0),mapTypeId   : google.maps.MapTypeId.ROADMAP
    };

    // create map               
    var map = new google.maps.Map( $el[0],args);

    // add a markers reference
    map.markers = [];

    // add markers
    $markers.each(function(){

        add_marker( $(this),map );

    });

    // center map
    center_map( map );

}

/*
*  add_marker
*
*  This function will add a marker to the selected Google Map
*
*  @type    function
*  @date    8/11/2013
*  @since   4.3.0
*
*  @param   $marker (jQuery element)
*  @param   map (Google Map object)
*  @return  n/a
*/

function add_marker( $marker,map ) {

    // var
    var latlng = new google.maps.LatLng( $marker.attr('data-lat'),$marker.attr('data-lng') );

    // create marker
    var marker = new google.maps.Marker({
        position    : latlng,map         : map
    });

    // add to array
    map.markers.push( marker );

    // if marker contains HTML,add it to an infoWindow
    if( $marker.html() )
    {
        // create info window
        var infowindow = new google.maps.InfoWindow({
            content     : $marker.html()
        });

        // show info window when marker is clicked
        google.maps.event.addListener(marker,'click',function() {

            infowindow.open( map,marker );

        });
    }

}

/*
*  center_map
*
*  This function will center the map,showing all markers attached to this map
*
*  @type    function
*  @date    8/11/2013
*  @since   4.3.0
*
*  @param   map (Google Map object)
*  @return  n/a
*/

function center_map( map ) {

    // vars
    var bounds = new google.maps.LatLngBounds();

    // loop through all markers and create bounds
    $.each( map.markers,function( i,marker ){

        var latlng = new google.maps.LatLng( marker.position.lat(),marker.position.lng() );

        bounds.extend( latlng );

    });

    // only 1 marker?
    if( map.markers.length == 1 )
    {
        // set center of map
        map.setCenter( bounds.getCenter() );
        map.setZoom( 16 );
    }
    else
    {
        // fit to bounds
        map.fitBounds( bounds );
    }

}

/*
*  document ready
*
*  This function will render each map when the document is ready (page has loaded)
*
*  @type    function
*  @date    8/11/2013
*  @since   5.0.0
*
*  @param   n/a
*  @return  n/a
*/

$(document).ready(function(){

    $('.acf-map').each(function(){

        render_map( $(this) );

    });

});

})(jQuery);

我尝试过这段代码但没有用过：

$( ".map" ).click(function() {

    google.maps.event.trigger(map,'resize');
    map.setCenter(center);

});

解决方法

var map = new google.maps.Map( $el[0],args); //locally scoped in render_map($el)

1)map变量未全局声明.

因此,当您尝试执行以下代码时,您将遇到错误.

$( ".map" ).click(function() {
    google.maps.event.trigger(map,'resize');
    map.setCenter(center);
});

试试#1

尝试将地图更改为全局变量.

试试#2

将其作为委托事件处理程序,并将以下代码添加到render_map($el)方法.

$(document).on('click','.map',function() {
    google.maps.event.trigger(map,'resize');
    map.setCenter(center);
});
